"Oregon Short Line's Stations Completed -- Ogden, April 4. -- J. L. Eckert, manager, and J. H. Marshall, superintendent of construction for the Eckert Construction company, were in the city today, having just completed three new railroad stations between Salt Lake and Ogden, for the Oregon Short Line, at Roy, Clearfield and Layton. The stations, which cost $8,000 each, will not be used, however, until the completion of the double track between Farmington and Ogden. The work of ballasting the twenty-one mile strip will be started next Monday and rushed to completion. The curves in the track have been reduced, making it possible for the railroad to cut down its present forty-five minute schedule between Ogden and Salt Lake." (Salt Lake Herald Republican, April 5, 1912)

June 11, 1912
"The new double track of the Oregon Short Line north of Farmington was placed in service Tuesday night [June 11], as far as to a point within three-quarters of a mile south of Layton, and is now in regular use.

The track north of Clearfield is to be surfaced and ballasted, but soon that portion that work will be finished also." (Deseret Evening News, August 1, 1912)

August 10, 1912
The following comes from the August 10, 1912 issue of te Ogden Standrd newspaper.

Short Line's Double Track -- Thc Oregon Short Line's new double track between Ogden and Layton will be formally turned over to the traffic department tomorrow by the construction department, this being the connecting link of double-track between this city and Salt Lake.

The entire distance is thirty-six and three-tenths miles and about nine months have been consumed in actual construction. The work was begun about a year ago but cold weather stopped a portion of the work for two or three months.

Not only is this the longest continuous piece of double-tracking on the Oregon Short Line, but in the entire state, and, according to competent judges of construction, is an exceptionally fine piece of work. It will add much to the general efficiency of the road as well as added safety to the traveling public.

February 1, 1913

February 6, 1923
ICC authorized SP control of CP, including provisions of previous agreement for preferential treatment with UP through Ogden.

This was the start of the Ogden gateway case because it allowed (forced) SP to solicit traffic for interchange with UP at Ogden that originated on SP north of Santa Margarita and Caliente, California, and south of Kirk, Oregon. This was essentially the same lines of separation line as an earlier internal agreement between UP and SP under Harriman control that decided which gateway would be used, Ogden for UP traffic or El Paso for SP traffic.

February 27, 1923
UP management in New York City approved the construction of what was called the Ontario Branch Extension. According to the accompanying documentation for the authorization, the branch was built to secure a greater portion of the ore traffic (about 65,000 tons per year) from Park City mines that used the Ontario Drain Tunnel. Most of the traffic was going by way of the D&RGW. (Union Pacific AFE 19, approved February 27, 1923)

March 29, 1923
Union Pacific Railroad organized Utah Parks Company as a subsidiary of the railroad. The company was incorporated in Utah.

Union Pacific changed the crew districts in Wyoming and Utah. Freight and passenger trains would operate between Green River, Wyoming, and Ogden, Utah, without changing crews at Evanston, Wyoming, effective at midnight on Thursday March 11, 1926. As a result of the change, 150 families were set to move from Evanston to Ogden. "Further changes affecting Evanston are anticipated when the double-tracking between Gateway and Echo is completed this summer. This change will cut the running time between Ogden and Green River during the summer and fall months when thousands of cars of perishable goods are shipped to eastern markets from coast points. More than 85,000 cars were handled last season, and this number is expected to be increased to 100,000 in 1926. Local Pacific Fruit Express officials say that in the future shipments will save between 30 and 45 minutes in operating time." (Ogden Standard Examiner, March 12, 1926)

November 10, 1926
"Roundhouse Plans Expected Soon. Ogden, Nov. 10. Blueprints of the proposed Union Pacific system roundhouse here are expected to arrive soon, according to word received by Ogden contractors Tuesday from Omaha. Until the plans arrive there is no definite information concerning the new building. The Union Pacific has opened its shops in Evanston, Wyo. They have been closed since last spring." (Salt Lake Telegram, November 10, 1926)

(Read more about the UP roundhouse in Ogden, completed in 1927)

Union Pacific's Utah Parks Company began operating the facilities at Grand Canyon National Park, and took over the interests of Utah & Grand Canyon Transportation Company, the bus company that was operating the bus service between Union Pacific's passenger trains at Cedar City and Cedar Breaks National Monument, Bryce Canyon National Monument, Zion's Canyon National Park, and Grand Canyon National Park. The bus company had begun the service in 1923. (Poor's, 1929, p. 1052)

(Union Pacific changed the name of the bus company to Union Pacific Stages.)

June 30, 1927
New roundhouse in Ogden. The following comes from the June 30, 1927 Ogden Standard Examiner newspaper:

Union Pacific Forming Crews. Hires Several Men From Force Displaced In S. P. Shops. Organization of Union Pacific roundhouse and machine shop crews was started this morning by William Parry, terminal general foreman, who announced that 64 men will be employed in these portions of the railroad's new Ogden activities. Twenty-five of the employees are being shifted from the Southern Pacific shops, others coming largely from Evanston, Wyo.

Besides the roundhouse and machine shop forces, divided into three shifts, there will be the employees of the storehouse, making a total of considerably over 125 men, according to present indications. At the present time nearly 100 men are employed in completing the building and grading work at the roundhouse grounds.

Although coaling of Union Pacific locomotives was started to some extent today at the new yards, the official change of machine and roundhouse work will not take place until midnight. Then 114 employees of the Southern Pacific railroad, including many experienced men, will lose their positions as far as the Southern Pacific shops are concerned. The expectation is that some of these will be re-employed here as business increases while others may seek positions in shops elsewhere.

The coaling station at Carp, Nevada, was demolished in 1928. (Walter R. Averett, Through The Rainbow Canyon, page 53, with photo)

Union Pacific leased Los Angeles & Salt Lake, Oregon Short Line, and Oregon-Washington Railway & Navigation for operation. ("Union Pacific Unification", ICC Finance Docket 9422, dated July 26, 1935, in 207 ICC 543.)

"Lease Of Properties Of Subsidiary Railroad Companies — For many years the properties of the Union Pacific Railroad Company and those of the Oregon Short Line Railroad Company, Oregon-Washington Railroad & Navigation Company, Los Angeles & Salt Lake Railroad Company and The St. Joseph and Grand Island Railway Company have been operated under one control and management but the operations of the properties of each company were for its account and it was necessary to keep accounts and statistics and make separate reports to regulatory commissions and others for each company. Effective January 1, 1936, the properties of the other companies were leased to and are being operated by the Union Pacific Railroad This made possible the centralization at Omaha of all accounting and treasury work in connection with the railroad operations and the discontinuance of the separate Accounting and Treasury Departments which had been maintained by the lessor companies at Salt Lake City, Portland, Los Angeles and St. Joseph, with a resultant saving in expense (after the first year) estimated at $472,000 annually." (Union Pacific Annual Report for 1936)

"Meets Train In Echo Race" -- "Miss Helen Keating, purchasing agent for the Utah Idaho Central railroad, tied the Union Pacific's fast Pony Express train in an auto race from Ogden to Echo in Weber canyon last week. Miss Keating had reservations for Denver, but decided to drive with a friend as far as Echo. The train crew didn't think she'd make it, but her auto pulled to a stop just as the train did." (Ogden Standard Examiner, May 30, 1937)

... found while researching the history of UP's Pony Express train. This would have been before the road was paved. Must have been quite a trip. Pacing the train the last couple miles into Echo would have been great fun.

October 7, 1937
LA&SL completed removal of the seven-mile Newhouse Extension, Mile Post 16.5 (Frisco) to Mile Post 23.5 (Newhouse, end of branch) of the Frisco Branch. The removal was done under Work Order 934. The Newhouse Extension had been completed in September 1904 to connect with Samuel Newhouse's Newhouse Mines & Smelting mill railroad, the Newhouse, Copper Gulch & Sevier Lake Railroad, which shut down in 1927.

The Newhouse Extension was an extension of the Frisco Branch. Regular service on the Frisco Branch had ended in 1931 with the shutdown of the old Horn Silver mine by the Tintic Lead Company, which had bought the property in 1928. The Newhouse Extension was washed out in several places during 1934 and 1935. Passenger service to Newhouse had ended in 1928.

In 1937 Union Pacific's depot was the only structure remaining in Newhouse and at Frisco there was only the railroad's depot and two houses. Work on removal of the Newhouse Extension was begun on September 10, 1937.

The railroad had applied to abandon the entire Frisco Branch, along with the Newhouse Extension. But the ICC imposed a two year test period, at the suggestion of the Utah State Industrial Development Board, to allow development of potential mine traffic, from Frisco to Milford. (Abandonment approved by the ICC in Finance Docket 10623, effective May 22, 1937, in 221 ICC 309)

"Refrigerator Traffic" "Pacific Fruit Express reports about 300 refrigerator cars of fruit moving into Ogden on the Southern Pacific daily. This figure, 10 per cent above the similar period last year, is expected to continue into the last of September, when it will increase to around 500 per day." "At present, about 50 of the daily 300 are grapes. Idaho potatoes make up 100 cars, and onions, green peas, and other products bring the Idaho movements to 135 cars daily." (Ogden Standard Examiner, August 21, 1938)

September 28, 1938
"Fruit Traffic Running High" "California Sending Large Amounts Eastward Through Ogden" "California fruit and vegetable shipments through Ogden are near their seasonal peak -- 400 to 500 carloads each day -- said the Pacific Fruit Express Co. today." "About half the movement consists of grapes, which are moving from California in huge quantities." "In addition, about 200 carloads of potatoes and apples are being shipped from Idaho each day." "Very few refrigerator cars are iced at Ogden at present, said officials. Most of the cars are iced before loading, with one re-icing either at Kansas City or Council Bluffs." (Ogden Standard Examiner, September 28, 1938)

September 30, 1938
Union Pacific (LA&SL) completed removal of 6.56-mile portion of Fairfield Branch, from Mile Post 23.6 (Five Mile Pass) to Mile Post 30.16 (Topliff, end of branch), including 7.03 miles of spur tracks extending from Topliff, southeasterly to the limestone quarries of American Smelting & Refining Company and United States Smelting, Refining & Mining Company.

The limestone quarries had been opened in 1906 and their operation was abandoned in November 1937. (ICC Finance Docket 11983, 228 ICC 223, approved June 3, 1938; removal date from "Return to Questionnaire" for ICC Finance Docket 13762)

August 1, 1939

Western Pacific's diamond crossing of the LA&SL freight line at 1400 West on Salt Lake City's west side, was changed from mandatory stop of all trains on both railroads, and proceed after determining a safe crossing (in accordance with Utah state law), to an automatic interlocking. (Western Pacific Eastern Division timetable #33, June 17, 1940)

The WP timetable included the following rule.

"U. P. CROSSING -- M.P. 926.3, Automatic Interlocked.
Home signals 300 feet east and west of crossing two-position color-light type, approach lighted indications, red (stop) and yellow (proceed with caution). Normal position red.
Fixed distant signals, semaphore type, 2020 feet west and 1750 feet east of home signals.
Approach lighting circuits start at distant signals. If no train or engine within interlocking limits, yellow indication will show in home signal after engine passes distant signal.
When home signal indicates "stop", and no train movement is evident on intersecting track, trainman will proceed to crossing and operate time release marked "WP" in iron box marked "Release" at crossing (Instructions in box). If signal does not change to "proceed with caution" after two minutes, be governed by Rule 663.
If a train or engine is standing between home signals on intersecting track, thorough understanding must be had with its crew before proceeding."

The associated LA&SL Los Angeles Division Special Rules #3, dated August 1, 1940 included the following, with no additional instruction.

"Salt Lake City. (M.P. 781.3 Freight Line) W.P. U.P. Automatic Interlocking Signals."

September 6, 1940
Union Pacific, LA&SL, and D&RGW received federal ICC approval for UP to access the Spanish Fork sugar factory of the Utah-Idaho-Sugar company. The ICC approved an agreement dated October 11, 1939 and signed by the railroads and the sugar company, and would allow Union Pacific trackage rights over the following: (1) after leaving its own Provo Subdivision mainline, approximately 1.038 miles over the sugar company's private Lake Shore Spur to its connection and crossing of the D&RGW Tintic Branch; (2) approximately 0.345 mile over the D&RGW Tintic Branch; (3) approximately 1.593 miles of D&RGW sidings and spurs from its Tintic Branch to the sugar factory, including an additional 0.505 mile over the Salt Lake & Utah spur that served the sugar factory. D&RGW and Salt Lake & Utah had jointly served the sugar factory under an agreement signed on October 1, 1918. Construction was to begin by November 1, 1940, and be completed by March 1, 1941. (242 ICC 55; ICC Finance Docket 12812, decided September 6, 1940)

Although the USGS topographic map for Spanish Fork in 1948 shows a connection, research suggests the connection between UP and D&RGW, by way of the private Utah-Idaho Lake Shore Spur was never completed. Mark Hemphill wrote on June 2, 2019, reporting that "the 1951 edition of D&RGW General Traffic Circular 36-E, which shows who served each industry at each competitive point, shows Utah-Idaho Sugar at Spanish Fork as Rio Grande track served by Rio Grande only -- not a reciprocal switch and not with UP access."

OSL received Utah Public Utilities Commission approval to close the agency at Hyrum, on the Cache Valley Branch. (Public Service Commission of Utah, case 2478)

March 15, 1942
The joint depot at Mammoth, Utah, was destroyed by fire. The depot measured 20 feet by 76 feet. (LA&SL Work Order 2272; Retire Mammoth depot; Work order closed on October 22, 1942)

On March 15, 1942 the Mammoth depot building was completely destroyed by fire. In the insurance claim documents, the superintendent stated that the fire had likely been caused by children playing around the unmanned structure, and that it would be replaced. However, on November 7th, the 20 feet by 76 feet building, or rather what was left of it, was formally retired. Prior to 1933, the depot building had been used as the location of a joint agency station for both D&RGW and LA&SL. In October 1933, LA&SL removed its agent, who had been serving as the joint agent for both D&RGW and LA&SL. After 1933, the agent at Eureka was responsible for car orders and the paper work associated with car shipments.

In May 1942, Union Pacific retired and removed the western 1.15-mile portion of the Evona Branch, between the connection with the OSL main line (branch Mile Post 3.77), and the crossing with the Roy-Hot Springs Road (Highway 91), branch Mile Post 2.62. (Work Order 89) The Evona Branch was built as the original Utah Central main line in 1869 and became a secondary main line in 1906 after OSL completed its six-mile Sand Ridge Cut Off into Ogden. (Public Service Commission of Utah, case 2544, approved March 30, 1944)

The portion of the branch to be abandoned had only been used for the storage of cars since 1912 when OSL completed the second track on the new main line. (Public Service Commission of Utah, case 2544) In July 1930 the state began improving Highway 91 by building a new "modern" concrete bridge over the 1906/1912 built OSL main line. (Public Service Commission of Utah, case 1176)

(Abandonment for the portion of the Evona Branch west of the highway crossing was requested because the state wanted to pave the entire route of Highway 91 between Roy and Hot Springs and Union Pacific did not want to pay for a highway crossing for the branch.)


June 30, 1942
LA&SL received Utah Public Utilities Commission approval to close the agency at Sandy. (Public Service Commission of Utah, case 2593)

July 21, 1942
OSL received Utah Public Utilities Commission approval to close the agency at Farmington. The last business for the agency had been to accept materials for the construction of the Mountain States Telephone & Telegraph transcontinental cable. Woods Cross is the next station to the south and Kaysville is the next station to the north. Approval to remove the Farmington depot building was given on July 26, 1948. (Public Service Commission of Utah, case 2599)

August 1942
Ogden Union Railway & Depot expanded the Ogden East Yard, also called Speedway or Riverdale Yard. On August 5, the Utah Public Utilities Commission approved OUR&D's request to add two tracks to the 33rd Street crossing as part of the expansion, which included construction of the car repair track. (Public Service Commission of Utah, case 2608)

In 1942, OUR&D built its new East Yard, which later became known as Riverdale Yard. The yard was greatly expanded in 1954.

September 11, 1942
Interstate Commerce Commission dismissed, rather than postponed, LA&SL's application to abandon the Fillmore Branch. The railroad had made application based on projected losses from wartime restrictions on petroleum products and to provide relay rail and other scrap materials for the war effort. The branch was not being operated at a loss. The application was denied because of protests of shippers. Union Pacific had requested an indefinite postponement due to new traffic of crushed volcanic stone, as cinder ash, for use on manufacture of cinder block needed in the war effort. (ICC Finance Docket 13771)

September 11, 1942
ICC dismissed LA&SL's application to abandon the Fairfield Branch, from Mile Post 0.8 (Cutler) to Mile Post 23.6 (Five Mile Pass, end of branch). The application was made on May 23, 1942. (ICC Finance Docket 13762)

On August 24, 1942 Union Pacific withdrew the application because new traffic developed which required that the branch remain in service. The operation of the new Geneva Steel plant at Orem required a special type of clay for use in the mortar of the fire bricking in the blast furnaces. The closest source for the clay was in a quarry which was located on the Union Pacific's Fairfield Branch. The clay was required in quantities that could not be furnished by trucks from the quarry. (Minutes of ICC hearing, Salt Lake City, August 24, 1942)

In November 1942 Union Pacific was operating two trains per week over the Fairfield Branch. (Public Service Commission of Utah, case 2631)

November 1942
OSL retired and removed the western 2.9-mile portion of the Benson Branch from Mile Post 0 at Ballard Junction on the Cache Valley Branch, to Mile Post 2.9 at Benson. (OSL work order 428; Abandonment approved by the ICC on October 26, 1942, Financial Docket 13927, 254 ICC 810) The 8.17-mile Benson Branch was completed in October 1912, between Ballard Junction (Mile Post 3.53 on the Cache Valley Branch) and Benson Junction, in Logan, as a direct route (11.7 miles) for through traffic between Cache Junction and Logan, by-passing the Cache Valley Branch (15.3 miles) and the Wellsville Branch (23.9 miles). The branch was used seasonally for 90 days each year for the movement of sugar beets to the Logan sugar factory. The Logan sugar factory operated until 1926 and was dismantled in 1936. In the twenty-five years that the sugar factory was in operation, from 1901 to 1926, it processed 1.5 million tons of beets and produced 3.5 million hundred pound bags of sugar; in its peak year of 1920 the factory processed 100,000 tons of sugar beets. (Arrington: Eccles, p. 243)

December 1942
OSL retired and removed about a half-mile of track at the end of the Bear River Branch, from Mile Post 9.9 to Mile Post 10.6, at Bear River City. (OSL work order 439) The remaining portion of the branch was in service at least until 1951. The branch paralleled U. S. Highway 30, between Bear River City and Tremonton, from about Mile Post 3 to about Mile Post 7.

January 1943
OSL retired and removed the 1.24-mile portion of the Thatcher Branch from Thatcher at Mile Post 6.25 to Nelson at Mile Post 7.3. (OSL work order 461) The 7.3-mile Thatcher Branch was built in 1903 for the Utah Idaho Sugar Company to transport sugar beets from the region west of Tremonton to the sugar company's sugar factory at Garland. OSL purchased the line in 1922. (Public Service Commission of Utah, case 2621, approved October 19, 1942)

August 28, 1943
LA&SL completed removal of 15.29 miles of the Frisco Branch, from Mile Post 1.21 to Mile Post 16.5 (Frisco, end of track). The branch was retired on June 22, 1943, after abandonment was approved by the ICC on July 24, 1942. (Work order 2528; ICC Finance Docket 13611, effective September 24, 1942)

The federal ICC had approved the abandonment of the Frisco Branch on July 24, 1942. (252 ICC 803, Finance Docket 13611; Decided July 24, 1942, "Cases Disposed Of Without Printed Report")

October 8, 1943
Union Pacific issued Work Order and Authority For Expenditure to build a spur 194 feet long, and an engine house (16 feet by 60 feet) at Iron Mountain, Utah. The engine house was specifically needed to protect a recently assigned diesel switcher, which was to be used to switch rail cars at the three nearby iron ore mine plants. The project was funded by UP's own special "National Defense Project," which was funding set aside by the railroad specifically to support the war effort. There were three mining plants loading iron ore, and a diesel switcher was needed to expedite the timely movement of trains. The engine house was to be constructed with a wooden frame, covered with corrugated steel, and was to be equipped with an inspection and service pit, and necessary heat, water and lights. About 200 cars per day of iron ore was being moved to the Columbia Steel plant at Geneva, Utah, and to the Colorado Fuel & iron plant at Pueblo, Colorado. The use of a diesel switcher would be more efficient and economical than the use a steam locomotive with its associated coaling and water facilities. (Union Pacific internal communications dated October 8 and 21, 1943)

(Read more about iron mining at Iron Mountain, Utah)

Union Pacific built a new powerhouse at the Salt Lake shops. The new brick and concrete structure replaced an earlier powerhouse built in 1918. The new powerhouse used three large water-tube boilers to produce all of the steam needed for UP's entire Salt Lake City terminal. (The powerhouse was torn down in 1999, after UP closed the shops in 1998.)

February 11, 1944
The construction of the Grant Tower automatic interlocking in Salt Lake City was approved by D&RGW. The documentation to support the project shows that there was a 17-lever mechanical interlocking at the combined WP/D&RGW and LA&SL/D&RGW crossing along 700 West and South Temple streets. The formal completion date for the line change was December 20, 1952, and for the tower building itself, the formal completion date is shown as May 20, 1950. (D&RGW AFE records on file at Colorado Railroad Museum)

March 16, 1945
Union Pacific, in the name of Oregon Short Line, leased, with right to purchase, all of the trackage, facilities, and right of way of Southern Pacific's line from Corinne Junction to Corinne. OSL purchased the property, buildings and tracks on October 16, 1947. Southern Pacific had removed their remaining tracks from Corinne Junction to Ogden in 1942, except for a 962 foot stub at Corinne Junction, which they sold to Utah Idaho Sugar Co., for use as a beet loading station. OSL bought the spur from the sugar company on April 21, 1950. (Union Pacific engineering department records)

SP had been running their Promontory Branch trains over OSL between Ogden and Corinne since about 1903. In an unsuccessful 1936 request for abandonment of the Promontory Branch SP stated that most of their trackage between those two points was "gone, removed by parties unknown". (ICC Finance Docket 9791, 212 ICC 402)

October 1945
OSL retired and removed the 1.03-mile portion of the Evona Branch between the western end at Mile Post 2.62 (the end of the branch at the Roy-Hot Springs highway, U. S. 91) and the spur to the Ogden sugar factory, at Mile Post 1.59. (Work Order 1332)

(The remaining portion of the branch is still in service during 2003, serving the Farmer's Co-op and the former Pillsbury grain elevators.)

October 1945
OSL retired and removed a portion of the Thatcher Branch, from Mile Post 5.63 to Mile Post 6.25, at Thatcher. (Work order 1429) The siding for Thatcher was moved to the new end of track in November.

October 13, 1945
"The Union Pacific will receive from Fairbanks, Morse & Co., on November 1 a three-unit, 6,000-hp. Diesel-electric locomotive, which has been designed for a maximum operation of 65 m.p.h. This locomotive will be tested on a run from south of Salt Lake City, Utah, to Los Angeles, Cal., in freight hauling and possibly in passenger service. The Union Pacific will also receive a four-unit, 6,000-hp. Diesel-electric locomotive from the Electro-Motive division of the General Motors Corporation, which is to be tested between Green River, Wyo., and Ogden, Utah, under exact loads and conditions to determine comparison of performance of this unit with the Union Pacific's "Big Boys," or 4000 class, 4-8-8-4 type, locomotives. Later tests of the new locomotive will also be conducted between Salt Lake City and Los Angeles." (Railway Age, October 13, 1945, page 622)

February 28, 1946
UP retired and removed the 86-feet by 33 feet, double track engine house at Malad, Idaho, at the north end of the Malad Branch. The engine house was located just south of the wye tracks at Malad, on the west side of the tracks. A total of 200 feet of track in and near the engine house were retired and removed at the same time. (UP CE Drawing 1504, dated February 28, 1946)

Union Pacific completed its new dispatcher's office in Salt Lake City. The all-brick building was located at the southwest corner of North Temple and 3rd West (400 West). (Sanborn Fire Insurance Map, Salt Lake City, 1950, sheet 052)

June 3, 1947
Union Pacific's first diesel-powered freight train to operate between Salt Lake City and Los Angeles, departed Salt Lake City on the morning of Tuesday June 3, 1947. A second diesel-powered freight was scheduled to depart Salt Lake City in the afternoon of the same day. There were already 14 diesel switching locomotives assigned to Salt Lake City and vicinity, and UP had ordered 13 additional switching locomotives for the same service. (Deseret News, June 3, 1947, with photo of UP 1401A)

August 26, 1947
The first depot at Uintah, a Common Standard design, was burned on the morning of August 26, 1947. (Ogden Standard Examiner, August 26, 1947)

September 9, 1047
As part of Union Pacific's installation of Centralized Traffic Control between Salt Lake City and Caliente, Nevada, the railroad was building a new CTC building on land north of the Salt Lake City, on the southeast corner of the intersection of 3rd (400) West and North temple streets.

The new Salt Lake City-Caliente installation of 329 miles will increase Union Pacific CTC mileage to 967 miles (629 miles from Salt Lake City to Daggett, Cal.). Cost of installations in operation and under construction is $13,394,000.

Control of the new territory from Salt Lake City to Caliente will be effected from a centralized traffic control building now under construction on Union Pacific property on the southwest corner of 3rd West and North Temple streets. This one-story, fireproof, air conditioned building is being constructed by the Paulsen Construction Co. The building and installation of equipment will cost $130,000. It will house chiif dispatchers' offices, machine room and other offices. (Salt Lake Tribune, September 9, 1947)

November 3, 1947
OSL received ICC approval to abandon the 2.98-mile College Branch, between College Junction, on the Cache Valley Branch south of Logan, to College. The line had originally been constructed in 1873 as the main line of the narrow-gauge Utah Northern Railway between Ogden and Franklin, Idaho. It became the Cache Valley Branch in 1890, upon construction of a new standard-gauge line between Ogden and Pocatello, and in 1906 the line became a secondary line, with the completion of the Wellsville Loop through Wellsville and Hyrum, further south in the Cache Valley. The 2.78-mile western portion of the College Branch between Mendon and College was abandoned in 1932. In 1945 the only traffic on the College Branch had been 23 carloads of beets and four carloads of potatoes. In 1946 there had only been 25 carloads of beets. (ICC Financial Docket 15790, in 267 ICC 640)

By October 1948, Union Pacific had sold all of the property between the junction and College. (Cache County Recorder's office)

November 14, 1947
OSL took possession of the 1.55-mile portion of the SP Promontory Branch (originally the 1869 Central Pacific main line) between Corinne Junction and Corinne. Union Pacific had used the line under trackage rights since July 1903 as part of the operations of the Malad Branch. SP had abandoned their Promontory Branch in 1944. (Union Pacific internal communications dated March 14, 1956 and June 26, 1956; Union Pacific Work Order 4902, approved on August 14, 1956, completed on September 20, 1956)

Southern Pacific sold the following structures on the dates shown, but the buildings remained on railroad property:

No property taxes were paid by SP, or the new owners after the "sales" in 1942. After an assessment in 1956 by the Utah State Tax Commission, Union Pacific internal communications indicate that although information from SP specifically referenced "sales" in 1942, additional documents furnished by SP in 1956 indicated leases rather than sales, with the leases (at $10 per year) assigned to UP by SP at the time of the sale of the Corrine properties in 1947. In 1956, UP proposed raising the leases to $25 per month to cover annual property taxes of $276.21 assessed in 1955, but was refused, and after an on-the-ground field inspection by Union Pacific personnel, UP canceled the leases and ordered that any and all buildings be removed from railroad property. These non-railroad-owned buildings included the following: 30 feet by 80 feet passenger and freight depot; 24 feet by 50 feet agent's dwelling; three bunk houses; two tool sheds; two chicken sheds; a cook house; two wood sheds; two scrap bins; five miscellaneous outbuildings; 708 feet of 1-inch water line, and a gasoline storage tank with pump and filler pipe.

Union Pacific installed Centralized Traffic Control between Salt Lake City and Caliente, Nevada. Included was a new dispatchers building located north of the Salt Lake City passenger depot, to house the communications equipment, and personnel needed to operate the new control system and control the train movements. This building later became the South-Central District train dispatching center. (Union Pacific annual reports for 1947 and 1948)

Union Pacific (LA&SL) completed installation of Centralized Traffic Control (CTC) between Salt Lake City and Caliente, Nevada. 329 miles, begun in 1947. (Moody's, 1959 p. 848)

Union Pacific purchased the western end, 1.9 miles in length, of the D&RGW San Pete Valley Branch after it was abandoned in December 1947. The line connected with UP's LA&SL subsidiary at Nephi and served the plaster mill at the mouth of Salt Creek Canyon, east of Nephi. The line became LA&SL's Nephi Plaster Mill Spur. the spur ran down the middle of Nephi's main east-west thoroughfare, First North Street, which was also designated as Utah Highway 132. The spur was retired and removed in October 1953 at the request of the state highway department, which wanted the tracks removed to allow improvements along the state highway.

January 6, 1948
"Union Pacific ran its last regularly scheduled steam locomotive out of Los Angeles Union Station on January 6. It was at the head end of the second section of the Pony Express. UP now uses diesels on all through passenger trains between Los Angeles and Salt Lake City." (Trains magazine, March 1938, page 62)

March 24-26, 1948
The American Freedom Train came to Salt Lake City via Western Pacific. It was displayed at Salt Lake City on March 24th, at Provo on March 25th and at Ogden on March 26th, before going to Pocatello, Idaho, via UP.

March 1948
The following comes from the online ICC Reports, Standard Time Zone Investigation No. 10122, decided March 31, 1948 (270 ICC 15) 

Two important dates come from this ICC report: February 29, 1948, when the railroad was rearranged and division end-points were changed; and April 11, 1948, when new operating agreements went into effect.

The rearranged railroad was covered in the issue of new employee timetables for the entire UPRR and its subsidiaries. These new timetables were compiled into a single book and are still available from Union Pacific Historical Society.

Quoting portions of the ICC report... 

[Under an order decided in 1928...] The boundary line between the United States standard Mountain and Pacific time zones was defined so as to run from Salt Lake City, Utah, in a southwesterly direction immediately north of and parallel with the Los Angeles & Salt Lake Railroad to the boundary line between Utah and Nevada near Uvada, Utah. The effect was to provide Mountain time for all points in Utah on and south of the line referred to. [The Mountain time also was extended along certain lines of the LA&SL from the Utah-Nevada state line to Caliente, Nevada.]

The main line which petitioner would have us except from the Mountain zone extends from the Utah-Nevada State line near Uvada to Salt Lake City, via Tintic, Utah, a distance of 282.8 miles. There is also an alternate route between Lynndyl, Utah, and Salt Lake City via Provo, Utah, used principally for freight, 134.1 miles in length; and there are seven branch lines in Utah aggregating 110.6 miles, a total mileage of 527.5 miles, all of which would be included in the exception. While this is a very substantial mileage to be operated under an operating exception, the zone line actually runs along the main line of petitioner from Salt Lake City to the Utah-Nevada boundary, so that, as to the greater portion of the mileage, the practical effect of the operating exception requested would be to transfer the zone boundary, for operating purposes only, from one side of the main line to the other.

The reasons for the modification sought by the petitioner are, essentially, changes in the flow of its traffic and an improvement and modernization program, including the substitution of Diesel for steam power and the installation of centralized traffic control. The petitioner is comprised of five corporate properties, one of which is the Los Angeles & Salt Lake Railroad Company. These properties have been and are now operated as three districts [Eastern, Northwestern, South-Central]. Operating divisions were established and restricted to conform to the limits of these corporate properties, but with the continuous development of traffic within and through the West, these district lines and operating divisions have become an impediment to the movement of through traffic. The petition states that to meet this changed situation petitioner has been and now is engaged in a system-wide program of modernizing its facilities and streamlining its operations.

In pursuance of this improvement program, effective February 29, 1948, the portion of petitioner's line between Los Angeles and Salt Lake City was established as a single division [California Division] in lieu of the two previous divisions, one extending from Los Angeles to Caliente, and the other from Caliente to Salt Lake City. To expedite train movements and save time previously lost at terminal points in changing engines, Diesel engines for both passenger and freight trains are now operated through, without change, over the entire distance between Salt Lake City and Los Angeles. Heretofore, between Los Angeles and Salt Lake City, all train and engine crews changed at Caliente, the present time-breaking point. Under the rearrangement, freight-train crews and both passenger- and freight -engine crews will change at Las Vegas, Nev., and at Milford, Utah. Passenger-train crews will operate from Las Vegas all the way into Salt Lake City. Under the operating rearrangements, train and engine crews will run in both directions through Caliente, and will have to change the time of their watches en route unless a change in the operating exception is made.

Petitioner now operates daily in each direction, 7 freight trains and 4 passenger trains, a total of 22 trains, through the present time-break point at Caliente and the zone boundary at the Utah-Nevada State line. The proposed exception will avoid hazards resulting from time changes in the middle of train movements.

After extended negotiations, an agreement covering the proposed changes has been reached by petitioner with its operating employees, under which Caliente and Lynndyl will be eliminated as operating terminals, effective April 11, 1948.

May 1948
UP Lynndyl Roundhouse -- LA&SL retired and removed the roundhouse at Lynndyl, leaving just two stalls along the east side that were connected to the machine shop. (UP drawing prepared on May 25, 1948, showing 685 feet of track to be constructed as a result of the retirement of yard tracks and various shop ground facilities.)

(Read letters from 1939-1943, concerning proposed retirement of portions of UP's Lynndyl roundhouse.) (PDF; 18 pages; 11.3MB)

(View a drawing showing what was later retired in May 1948.)

May 1948
OSL retired and removed the entire 4.93-mile Urban Branch, between Bakers (OSL Mile Post 25.3) and Urban. (Work Order 2162) The branch was completed in 1918 and was used to move sugar beets to the Garland sugar factory, on the Malad Branch. Beet dumps were located at Natal, Teal, and Urban.

In the six year period from 1941 to 1946, the traffic on the Urban Branch amounted to only 105, 79, 72, 75, 49, and 36 carloads, respectively, all of which were loaded at the beet dumps at Teal, at Mile Post 2.6, and at the end of the branch at Urban. The only trains on the branch were operated about one per day, for the duration of the thirty day beet harvesting season.

The decline in traffic was attributed to the steady decrease in the number of acres that have been planted in sugar beets in the region east of the Bear River. (Abandonment approved by the ICC in Financial Docket 15740, dated November 3, 1947, in 267 ICC 634) The siding at Bakers, Mile Post 25.6, was retired in 1949 (Work Order 2168), while Bakers Spur, at Mile Post 25.3 on the east side of the main line, was retired in December 1947 (Work Order 2162).

July 28, 1948
Union Pacific received Utah Public Service Commission approval to remove the depot building at Farmington. Approval to close the agency was given on July 21, 1942. (Public Service Commission of Utah, case 2599)

August 13, 1948
Union Pacific received Utah Public Service Commission approval to abandon its Weber Mine Spur at Coalville, Utah. The spur had been built in 1917-1918, and was 2.57 miles in length, in a general northeasterly direction from Coalville. Trains had been operating at irregular intervals, and there had been no regularly scheduled trains. The Weber mine was operated by the Park Utah Consolidated Mines Company, and active mining had stopped on May 16, 1944 due to a fire in the underground working areas. The working areas in the mine where the fire had occurred had been sealed off by concrete bulkheads. There was 'considerable" amounts of old "slack" coal located on the surface at the mine, and during 1946 a total of 21 car loads of this slack coal had been shipped. But during 1947, only 12 car loads of slack coal had been shipped. Continued operation over the spur track, and projected traffic on the spur, did not justify the cost to maintain the spur. Any future shipments can be handled by motor truck to a loading site in Coalville, adjacent to the Union Pacific Park City Branch. Revenue from the spur during 1947 had been $1,764.00, and expenses to provide the service had been $2,540.00, for a net loss of $766.00. The application had been submitted on July 10, 1948. (Utah Public Service Commission Case 3292)

December 5, 1948
The new dispatchers building in Salt Lake City. From the December 5, 1948 issue of the Salt Lake Tribune newspaper: "At the corner of 3rd West and North Temple, a little red brick building stands in a grove of trees. Inside this structure, men responsible for the smooth flow of Union Pacific trains spend their working day literally flipping switches. The building is home to some 35 dispatchers, whose U. P. line of authority extends from Salt Lake City to Caliente, Nev., and to McCammon. Ida." "Since the initial Salt Lake installation of C T C (centralized traffic control) last February..." (Salt Lake Tribune, December 5, 1948)

Union Pacific completed removal of the 2.6-mile Weber Mine Spur, from Coalville to the Weber Mine in Chalk Creek canyon. (Work Order 6926, UP Drawing 19564, UP Drawing 36268, Park City Branch)

January 1949
OSL retired and removed the 1.57 portion of the Logan Sugar Factory Branch between Logan Junction and the branch's crossing of the Logan River at Mile Post 0.9. (Work order 2617) Included in the abandonment was the one-mile portion of the original branch, from the river to College Junction, along with the 0. 58-mile portion of the College Branch from Logan Junction to College Junction that remained after the College Branch was removed in November 1947. The remaining 0.9 portion of the Logan Sugar Factory Branch is in service today as the Sugar Factory Spur, from Sugar Factory Junction to the river.

February 1, 1949
Union Pacific received Utah Public Service Commission approval to discontinue Trains 559 and 560 between Ogden, Utah and Malad, Idaho. The two passenger trains provided service by using two "motor passenger coaches" (McKeen or other motor cars). One motor car was designated as Train 559 northbound, departing Ogden at 8:15 a.m. and arriving Malad at 11:00 a.m. The other motor car was designated as Train 560 southbound and departed Malad at 3:15 p.m. and arriving at Ogden at 5:45 p.m. (Utah Public Service Commission case 3291)

Union Pacific had initially applied to discontinue the two trains during 1941, and the Commission had denied the application on January 23, 1942. Union Pacific appealed the Commission's decision to the Utah Supreme Court, which found in favor of the railroad, reversing the Commission's denial on December 12, 1942. On January 27, 1943, the Commission issued its order allowing Union Pacific to discontinue Trains 559 and 560. But the trains' discontinuance was blocked by the Public Utilities Commission of Idaho due to the war emergency. Following the war, patronage of the two trains had declined considerably. The Utah Supreme Court's denial had been based in part on the lack of parallel motor bus route, but following the war, there were now two parallel bus routes, providing morning and evening service on both directions, on schedules that were faster than the train service. With these considerations, Union Pacific applied to the Public Utilities Commission of Idaho to discontinue the two passenger trains, and the Idaho commission held a hearing on September 21, 1948. The Idaho commission approved the application to discontinue the Idaho portion of the service on December 21, 1948. Union Pacific was allowed to replace the two passenger trains with Mixed Train service, with service for passengers and their baggage, as well as providing express service.

Most of the roundhouse and associated tracks at Caliente, Nevada were retired and removed. Also retired and removed were the seven yard tracks that paralleled the main line. This change essentially shut Caliente down as a division point on the LA&SL. A few tracks were trained, including the turntable (126 feet in length), seven turntable tracks, the five southern-most roundhouse stalls and two of the approach tracks to the south of the turntable. the wye tracks north and south remained in place, and were used by the Pioche Branch. (Union Pacific Work Order 4249, approved January 21, 1949; completed March 28, 1950; the associated drawing for the proposed changes was dated November 18, 1948)

April 6, 1950
Union Pacific received Utah Public Service Commission approval "to discontinue its station at Stockton, Utah, as an agency station and reporting station." The building was to remain as a non-agency station. Because labor agreements would not allow one full-time agent to be responsible for two stations, the agent at Bauer could not fulfill the responsibilities of delivery and handling of express or L.C.L. freight at Stockton. Therefore, Union Pacific was "to appoint some responsible person at Stockton to be caretaker at Stockton depot," and the caretaker would be given a key to the Stockton freight house to allow shippers and customers to ship and receive shipments to and from Stockton, and to allow access to the telephone at the Stockton depot. The application had been submitted on August 9, 1949. (Utah Public Service Commission, Case 3436)

Union Pacific completed its new laundry building in Ogden. (Ogden Standard Examiner, July 27, 1952)

Union Pacific constructed what it called the "Post Office Annex" for lease to U. S. government. (Union Pacific 1951 annual report)

November 16, 1951
The U.S. Post Office began using its new parcel post sorting facility, located in the Union Pacific-owned Postal Annex building, located just south of UP's Salt Lake City depot. Work began in January 1951 and was completed in time for the Christmas rush. The building measured 125 feet by 225 feet. It was built by Union Pacific and leased to United States Post Office Department upon completion. (Deseret News, January 27, 1951; November 13, 1951; December 12, 1951)

3rd West Industrial Lead -- Union Pacific received federal ICC approval to build an industrial lead along 3rd (400) West, south from 9th South, to 21st South, a distance of 1.7 miles. The industrial lead was built to serve several existing and potential businesses and industrial companies that had requested the spur. The industrial lead crossed D&RGW's former Salt Lake & Utah line at about 1550 South, for which D&RGW protested and lost. Operation of the industrial lead was within Salt Lake City terminal limits, and was switched similar to the industries all along 3rd (400) West between 2nd South and 9th South. The line remained in place after the construction of Interstate 15, and the connecting access ramp to 9th South, with the access ramp including an overhead viaduct. The industrial lead was removed in 1999 when UP abandoned the entire line along 400 West as part of the I-15 upgrades, and as part of the gateway Project, but the overhead viaduct for 400 West remains in place. (282 ICC 741; ICC Finance Docket 17480, decided April 10, 1953)

The crews that worked along UP's 3rd West Industrial Lead, including the part of the Provo Subdivision north of 900 South, also provided service to the companies and industries along the 1.7 miles of the 3rd West Industrial Lead. The informal name for this job was the "Long Street Local," due to its length from 200 South in downtown Salt Lake City, south almost to 21st South.

"Completion Seen. -- Salt Lake City. -- The Union Pacific Railroad said yesterday construction of its new $100,000 north yard offices here will be completed by June 1. The 36 by 181-foot brick and reinforced concrete structure will house offices and clerical workers for the terminal master and train master." (Ogden Standard Examiner, January 25, 1953)

(View an architectural drawing of this yard office building.)

(These yard offices in Salt Lake City, located at about 700 North, were demolished in February and March 2019.)

The following comes from Railway Age:

$4 Million Expansion Planned at Ogden, Utah -- "To handle the heavy volume of traffic arising from the national defense effort and the rapidly expanding industrialization of the west," the Union Pacific and the Southern Pacific, through their jointly owned Ogden Union Railway & Depot Co., and Pacific Fruit Express, will spend $4 million on new and enlarged yard facilities at Ogden, Utah.

One of the major features of the project is expansion of the Ogden Union's East yard to permit handling all eastbound traffic. The present main yard will be used for westbound traffic. Plans call for 111,900 feet of new yard trackage; an overhead viaduct for the Bamberger Railroad; an overhead viaduct for highway traffic at 31st street; two yard office buildings; a diesel fueling station; two control towers; floodlights for both East and Main yards; a pneumatic tube system; radio and paging communication facilities; and a 15,0-ton track scale.

Parallel improvements planned by P. F. E. call for construction of an island-type icing platform with a capacity of 220 cars. Of two present island-type icing platforms, one of 70-car capacity will be retired while one of 66-car capacity will be retained for service.

Plans also call for three mechanical icing machines; a public address system; and a 500-ton ice storage facility with an ice conveyor system connecting it with the platform.

At the same time the UP will construct a four-track car repair yard with an auxiliary shop, office, locker room and storehouse building. (Railway Age, July 20, 1953, courtesy of Thorton Waite, photocopied article received on March 26, 2011)

October 1953
Union Pacific retired and removed the Nephi Plaster Mill Spur. UP had purchased the spur in 1948. The spur served the plaster mill of U. S. Gypsum Company and was the western portion, 1.9 miles in length, of the former D&RGW San Pete Valley Branch, abandoned by D&RGW in December 1947. The spur ran down the middle of Nephi's main east-west thoroughfare, First North Street, which was also designated as Utah Highway 132. The spur was retired and removed in October 1953 at the request of the state highway department, which wanted the tracks removed to allow improvements along the state highway. (Work Order 5272; end of track was at engineering station 108+39)

Union Pacific began offering trailer-on-flat-car service. The following comes from Model Railroader magazine, May 2016:

Q -- When did the Union Pacific get into the trailer-on-flatcar business?

A -- Though some railroads explored trailer-on-flatcar (TOFC) service as early as the 1920s, federal regulations limited the practice to short lines, short runs, and intra-state service. But an Interstate Commerce Commission ruling in 1954 clarified the legality of intermodal shipping, opening the doors to railroads nationwide. Quick to jump on the bandwagon that year were the Atchison, Topeka & Santa Fe; Baltimore & Ohio; Chicago & North Western; Great Northern; New York Central; Nickel Plate; Pennsylvania; and Wabash, among others. A year later, in 1955, Norfolk & Western, Pennsylvania, and Rail-Trailer Corp. combined forces to form Trailer Train.

The UP was among those that started experimenting with TOFC fairly early. Union Pacific flatcars outfitted exclusively for handling trailers first appeared in the Official Railway Equipment Register of January 1954. The 43'-3" flats pictured above appeared in the 1956 equipment register.

You could also run Trailer Train cars in interchange service anytime after 1955, though the UP didn't join Trailer Train until 1960.

The entire F-50-10 class in the 53000-53084 series were converted from 56000-series cars in July 1953, November 1953 through June 1954, and in November 1958. The entire F-50-10 class was built as 56000-series cars in September to December 1939.

(Color photos of UP Fruehauf and Trailmobile trailers, including two loaded on UP F-50-10 53008, are on the back cover of The Streamliner, Volume 18, Number 3, Summer 2004)

UP F-50-10 flat car 53019 was converted to TOFC service in December 1953, from its previous number of UP 56794, and is shown in the UP Equipment Record as "test car Pullman-Standard Trailmobile." Pullman-Standard bought control of Trailmobile in 1951, keeping the company as a separate business unit, known as Pullman-Trailmobile, Trailmobile Inc. Division of Pullman, Inc., until 1989.

June 1954
OSL retired and removed the remaining 5.2-mile portion of the Benson Branch from Benson, at the end of track, to Benson Junction in Logan. (Work order 4203)

(The wye at Benson Junction, along with about 1,000 feet of the branch, remains today as part of the Cache Valley Branch.)

July 16, 1954
UP retired and removed the 65,000-gallon water tank and two 12-inch Poage water standpipes at Farmingtom, Utah. One standpipe, and drain box was located on the north end of the station platform, east of the double track main line, and the second standpipe and drain box was located at the south end of the platform, on the west side of the double tracks. The water tank was located just east of the former site of the Farmington depot. (UP Utah Division CE Drawing 2171, dated July 16, 1954)

January 1955
"Now that all of its routes are protected by fast, non-extra-fare streamliners, Union Pacific is dropping two familiar names from its timetable -- the Denver-Los Angeles Pony Express, and the Chicago-San Francisco Gold Coast. Incidentally, removal of the Coast will be somewhat simultaneous with the complete streamlining of the San Francisco Overland on the same route for the first time in its 67-year life." (Trains magazine, January 1955, page 12)

August 2, 1955
Union Pacific formally opened the Diesel Locomotive Maintenance and Repair Shop in Salt Lake City. Announced to be built in October 1951. Construction started in December 1951. (July 20, 1955 "72055" Union Pacific news release; Salt Lake Tribune, August 3, 1955, p. 16; Railway Age, October 3, 1955, p. 34)

OSL closed the agency station at Trenton, and the work of the depot agent was moved to Cache Junction. The building was sold on May 18, 1956 to the Cache Valley Turkey Growers Association for $600 and was to be moved by January 1957. (Work order 4781; Public Service Commission of Utah, case 3248)

Under work order 4781, approved on May 3, 1956, the 24 feet by 99 feet depot was retired, along with the train order signal and a nearby 8 feet by 16 feet outbuilding. The depot consisted of a 24 feet by 64 feet combination freight and passenger depot, with a 24 feet by 35 feet extension added in 1917. The outbuilding was a combination coal storage and out house. The train order signal was a "No. 150 Assembly B, with Electric Light" with steel mast. The work order included the installation of a 8 feet by 10.7 feet prefabricated metal shelter building for passengers waiting for their train to arrive. The work order was commenced on July 13, 1956, and was completed on March 28, 1957. The foundation for the prefabricated building was completed on December 27, 1956. The depot building was actually moved on January 2, 1957.

GM's Aerotrain stopped in Salt Lake City (Salt Lake Tribune, March 12, 1956)

"9,500 Utahns See 'Aerotrain' On U.P. Swing Into State -- After being admired and examined by more than 9,500 Utahns, a forerunner of tomorrows passenger trains was on its way Sunday to other points on the Union Pacific Railroad.

"Aerotrain," a General Motors conception of modern rail transportation, was viewed Saturday and Sunday during stops at stations in Salt Lake City and Ogden.

"The 400-passenger prototype was lent to U.P. so the railroad's engineers could exhibit it and try it on the company's lines.

"Main difference in the 102-mile-an-hour train from present units, is that each 40-passenger, 32-ton car is cushioned by air-filled bellows rather than steel springs as the older 80-passenger, 65-ton models now being used.

"U.P. has no similar lightweight trains in operation, but is merely trying out the new design, officials said.

"Other stops are planned at Boise, Idaho, March 16 from 8 to 11 a.m. and at Pocatello, Idaho, March 16, between 7 and 9 p.m."

August 1957
"When it fills in an intermediate gap in 1958, Union Pacific will have C.T.C. all the way from Granger, Wyo., to Hinkle, Ore., 756 miles. Also, UP will then boast 2030 miles of C.T.C. systemwide -- more, it claims, than any other U.S. road." (Trains magazine, August 1957, page 12)

Union Pacific began using computers for its payroll and car movement data. Previously, car movement data had been by use of IBM punch cards.

Union Pacific donated the Honeyville depot to the National Society of the Sons of Utah Pioneers, at no charge. The depot was to be moved for display at Pioneer Village at Corinne, Utah. The depot was to be moved at the society's own expense by May 9, 1959, and placed on property leased by the society at Corinne, Utah. (Union Pacific Purchasing Department Sale Order No. 337, Omaha, dated March 30, 1959, with accompanying internal communications dated April 1, 1959)

UP joined Trailer Train, the national trailer-on-flat-car (TOFC) pool. UP's connecting road at Ogden, SP, also joined Trailer Train in 1960. Competing road WP started TOFC service, better known as "piggyback" service, in 1959 between Salt Lake City and Oakland. D&RGW joined in 1963. (The Tioga Group, Intermodal Timeline, 1954 to 1966)

January 1960
"NEW HOME FOR THE HYBRID: Union Pacific, a railroad known for variety in motive power, has picked up an odd one: Bamberger Railroad diesel 570, now UP 1270. Bamberger (which folded last year ) got the early road-switcher from Alco-GE in 1943. Although the few units built up to that time had been partly requisitioned for wartime use in Iran, the Utah electric rated One complete with heating boiler (and a trolley pole to throw signals ) for its troop trains. The Alco's silhouette became truly unforgettable in 1951, when upgrading at La Grange gave it an EMD hood." (Trains magazine, January 1960, page 14)

April 27, 1960
UP retired the small passenger shelter (10 feet by 12 feet) and gravel loading platform at Washakie, Utah, located on the Malad Branch near Portage, Utah. The shelter was served by the daily Malad Local mixed train. (UP Work Order 5761, completed April 27, 1960)

June 11, 1960
With the retirement of the last of UP's steam locomotives in late 1959, and steam locomotives no longer needing to be serviced at Ogden, the large coaling station was demolished and removed. A photo dated June 11, 1960 shows that the large coaling station was being removed at that time. The large and extensive overhead structure was already gone, with only the trackside vertical steel beams and minimal horizontal steel beams still in place.

September 25, 1960
UP combined its City of San Francisco and City of Los Angeles trains between Omaha and Ogden, as Train 103/104. At Ogden the train was split, with Oakland-bound passengers going by way of SP, and Los Angeles-bound passengers remaining on UP. (part from The Streamliners, Kratville, page 517)

Union Pacific Coal Company was dissolved and all properties transferred to the railroad, as part of the natural resources division. (Moody's, 1973 p. 511; Klein Volume 2, The Rebirth, page 484)

December 7, 1962
Union Pacific received approval from the Public Service Commission of Utah to discontinue the agency station at Wahsatch, Utah. The Commission allowed the agency station to be closed, and the depot building to be removed. The depot was to be replaced by a telephone and drop box for use by customers to leave and receive waybills and livestock contracts, and to communicate with the full-time agents at either Echo, Utah (25 miles west of Wahsatch), or Evanston, Wyoming (10-1/2 miles east of Wahsatch). The then-current agent at Wahsatch resided in Echo, and commuted each morning and evening to Wahsatch to perform his duties. (Public Service Commission of Utah case 5170)

"There have been no express shipments at the station of Wahsatch, Utah, either inbound or outbound, and no ticket sales or revenue of any kind from passenger service; and there have been no shipments of incidental items such as baggage and milk or cream from said Wahsatch station for several years. That for several years there have been no LCL shipments moving out from the station of Wahsatch, and in recent years there have been only one or two incidental shipments of LCL freight into Wahsatch, most of such shipments having been made by the applicant railroad itself or by construction contractors at times when there has been construction in the area."

"Over some years past there have been shipments of wool moving out from the station of Wahsatch in the spring, but the sheep men who range their sheep in the vicinity of Wahsatch in the summer have now discontinued shearing at Wahsatch and have sheared their sheep before leaving the desert in the spring, and there is now no wool being shipped out from the station at Wahsatch."

During 1959, 286 cars (253 sheep; 26 cattle) had been shipped from Wahsatch, and 229 cars (201 sheep; 13 cattle) had been received, along with a 1,000-pound LCL shipment. During 1960, 288 cars (256 sheep; 24 cattle) had been shipped, and 297 cars (263 sheep; 30 cattle) had been received, along with a 100-pound LCL shipment. During 1961, 204 cars (185 sheep; 13 cattle) had been shipped, and 214 cars (170 sheep; 14 cattle) had been received., along with a 200-pound LCL shipment.

The former Clearfield Naval Supply Depot was turned over to private ownership under the name of Freeport Center, Inc., a Utah corporation controlled by Russell W. Schmacher of Danville, California. Schumacher had purchased the surplus facility from the federal General Services Administration for $5,752,877. Freeport Center, Inc., took title to the supply depot on June 1, 1963. The concept of a freeport center was to take advantage of a recently passed law from the Utah state legislature to eliminate inventory taxes, and certain taxes on certain types of manufacturing. The former Naval Supply Depot had been the largest Naval supply depot in the western United States, and as a privately owned warehouse center, represented five percent of the public warehouse space available in the continental Unites States. The purchase included three miles of railroad line and a locomotive roundhouse. The earliest tenants included Whirlpool-Sears, Westinghouse Electric, and California Packing Corporation (Del Monte), along with Roger Brothers, an Idaho company that stored diced, sliced, mashed and dehydrated potatoes.

WP-UP Junction (WP M.P. 926.6), first shown in WP timetable System #2, dated June 1, 1967.

WP-UP Junction (UP M.P. 781.7), first shown in UP Utah Division #42, dated September 24, 1967.

WP-UP Junction, a double crossover at about 1100 West in Salt Lake City, was added in 1967 to replace the diamond-crossing at 1400 West. As noted above, Jeff Asay wrote that the change was to put the WP and UP(LA&SL) lines west from Salt Lake City, on a common alignment in preparation for what today is I-80, and the new superhighway's crossing over the two rail lines at Cheyenne Street (about 1550 West).

(In 1983, with the common ownership of both UP and WP lines after their merger, the need went away to crossover to WP-owned tracks before the ownership changed at the Jordan River, and the double crossover was moved 1-1/4 miles west to Orange Street, west of Redwood Road between 300 and 400 South.)

February-March 1967
Sometime in either February of March 1967, the local Promontory Chapter of National Railway Historical Society arranged for a group trip to ride the last UP mixed train providing passenger service between Provo and Salt Lake City. The group traveled from Salt Lake City to Provo by way of D&RGW's Prospector train. At Provo, UP provided a UP combination mail-baggage-passenger car, and a 500-series coach for the group to return to Salt Lake City. This was the last Union Pacific passenger train between Provo and Salt Lake City. (as recalled by Dave England)

October 11-12-13, 1967
The U. S. Post Office discontinued Railway Post Office service between Omaha, Ogden and San Francisco. RPO service was discontinued specifically on SP mail trains 21 and 22 between Ogden and San Francisco, and UP mail trains 5 and 6 between Omaha and Ogden, along with trains 101 and 102 (City of San Francisco) and trains 103 and 104 (City of Los Angeles). (U. S. Post Office letter dated September 21, 1967, from Postmaster in Ogden, Utah, to all affected employees, courtesy of Bob McKeen)

The last trip of RPO "Mobile Unit" service was on the following dates, on the following trains:

In 1968 D&RGW and UP began operation of a unit coal train between Sunnyside, Utah, and the Kaiser steel mill in Fontana, California. The train used dedicated full trains of high-sided gondola cars that were loaded at Sunnyside and unloaded at Fontana. The trains also used dedicated sets of SD45 locomotives from both Union Pacific (12 locomotives) and D&RGW (six locomotives).

(Read more about the operation of the Kaiser coal trains)

In 1968, Union Pacific completed its first automatic classification yard, named Edd H. Bailey Yard in honor of the railroad's president. Located at North Platte, Nebraska, it was built along side an existing classification yard that was completed in 1948. It became Bailey East in 1980 when the original yard, completed in 1948, was replaced by a new more modern automatic classification yard, which took the name Bailey West.

March-June 1968
On a date in the three-month period between March 10, 1968, and June 30, 1968 (the dates of the appliable Union Pacific public timetables), the three mixed train locals in northern Utah were discontinued. The Malad mixed train [Ogden to Malad] was UP Trains 311 and 312. The Cache Valley mixed train [Cache Jct to Preston] was UP Trains 303 and 304. The Provo mixed train [Provo to Salt Lake City] was UP Trains 305 and 306. All three were shown in the March 10, 1968 public timetable, but not in the June 30, 1968 public timetable.

September 18, 1968
St. John Station -- The Utah Public Service Commission held a public hearing for the closure of St. John as an agency station on Union Pacific. "Applicant alleges that inasmuch as there have been no passenger tickets sold at St. John for many years, and now Western Union business for over three years and no REA express business remaining, it is no longer necessary from the standpoint of convenience and necessity to maintain an agent at the St. John Station; and that incidental and miscellaneous service such as demurrage, sanding and bedding or similar items can be handled through the Agent at the station of Warner some 12 miles northerly from St. John; also that railroad billings and collections of freight are handled through the Agent at Warner rather than through the Agent at St. John; and there has come to be little or no business which would require the presence of an Agent at St. John." (Utah Public Service Commission case No. 5975, dated August 15, 1968; public notice in Salt Lake Tribune, September 2, 1968; article with photos in Tooele Transcript, October 18, 1968)

October 24, 1968
On October 24, 1968, in Case #6009, the Utah Public Service Commission approved UP's request to close the agency station at Devils Slide. The agent assigned was Glenn S. Ridge, and he apparently retired on January 30, 1969, after 57 years service. He had been Devils Slide station agent since 1956. (Utah Public Service Commission case index cards, Case 6009, Utah State Archives; Park Record, February 29, 1968; January 30, 1969)

Together with Salt Lake City, UP developed its Centennial Business Park on Salt Lake City's west side. (Read more about UP's west side business parks)

November 22, 1969
Santa Fe's Super Chief passenger train was detoured between Barstow, California, and Denver, Colorado, by way of Union Pacific's route through Las Vegas and Salt Lake City. It was reported that the detour was most likely because of the November 1969 derailment near Maine, Arizona. A westbound potash train with remote control mid-train helpers derailed when the helpers failed to stop pushing and jackknifed the train. Unfortunately, a eastbound high priority freight was passing it at the time and got derailed itself. The scene of the derailment was reported as being "spectacular, with debris everywhere." (Date and detour route from a Union Pacific internal "Telegram" dated November 22, 1969, advising of the details of the detour.)

During the 1960s and very early 1970s Union Pacific operated what was called the Sandy Local along the Provo Subdivision between Salt Lake City and Sandy. Most of the time of the local was taken by switching the two large smelters at Murray and Midvale.

Don Strack wrote on July 26, 2018: "Back in the early 1970s, myself and another local railfan were chasing UP's Sandy Local. I took a few photos (which are now lost), as we followed the train south from 900 South all the way to Pallas (5300 South). It was unique because it had two SW9s as motive power. They were MU'ed with cab-end facing MU plugs that had been installed the previous week in Salt Lake shops. I had been involved because as part of my boilermaker apprenticeship, I had been asked to draft the engineering drawing for the placement of the MU boxes. Sad to say, I do not recall the locomotive numbers. At Pallas something caused the train to big hole (go into emergency), so we went for lunch. After lunch, the train was gone from Pallas, and we found it tied up for lunch over by the smelter office in Midvale. I did not know that UP actually had a building in Midvale until James Belmont posted the a photo of the building."

Also during the 1970s there was a spur that from the east side of UP's North Yard, at the north end, at about 1300 North. The spur climbed a steep grade to the northeast and curved across Back Street to the Monroc quarry, at about 1700 North. The first 2,000 feet or so was still in place in early 2020, but is connected to UTA's Frontrunner track. The Beck Street crossing was three-tracks by 1970, but was gone by the time the first Google Earth image was taken in 1993.

Union Pacific moved its Salt Lake City freight offices from the freight depot at 5th West and 1st South, north to its North Yard freight office at 701 North 4th West. (Deseret News, May 7, 1970)

September 1970
The following comes from the September 1970 issue of Railroad magazine, through the courtesy of Thornton Waite:

Ogden, Utah, once a famous railroad center, no longer has a redcap employed in its Union Depot. The last two porters there have retired. This community is less than 75 miles from where the nation's first transcontinental railroad was joined. Twenty-five passenger trains once stopped at Union Depot daily, enough to keep 12 redcaps busy.

Today only one train--Union Pacific's City of Los Angeles, which runs between the West Coast and Chicago--brings passengers through on a daily basis. Three other trains, six if you count the round trips, pass through on a tri-weekly basis.


April-May 1971
The following comes from the April-May 1971 issue of Union Pacific's INFO magazine (UP Info magazine, Volume 3, Numbers 6 and 7, April-May 1971):

Amtrak (Railpax) -- As of April 16, 1971, Union Pacific has entered into a contract with the National Railroad Passenger Corporation as a result of which, effective May 1, 1971; Union Pacific has discontinued all intercity rail passenger service.

However, UP operates an NRPC train for that corporation between Denver and Ogden on a triweekly basis. This train, operated between Chicago and San Francisco, is routed over Burlington Northern between Chicago and Denver and over Southern Pacific between Ogden and the San Francisco area.

Utah Improvements -- A total of $4.8 million will be spent on the Utah Division, including the replacement of 63.83 miles of main line with continuous welded rail. Strings of the new rail are being installed between Cruz and Champlin.

New 133-pound rail will be installed in .88 miles between Curvo and Gateway. Rail of this weight has already been installed on .75 miles of curves between Pehrson and Lofgreen.

Resurfacing and lining between Ogden and Brigham City and between Wahsatch and Echo will use 29,100 cubic yards of ballast while tie gangs will replace 22,100 ties.

May 1, 1971
The following comes from Union Pacific's 1971 annual report:

Amtrak Takes Over Intercity Passenger Service -- On May 1, 1971 , the National Railroad Passenger Corporation (Amtrak) assumed from participating railroads responsibility for providing intercity passenger service. As a participating carrier, Union Pacific consequently discontinued all regularly scheduled passenger service. However, Amtrak contracted with the Railroad for operation of a regularly scheduled train running three times weekly between Denver, Colorado and Ogden, Utah, and for the right to call upon the Railroad to provide additional intercity passenger service desired by Amtrak. To date, Amtrak has called upon the Railroad to operate a few special passenger trains; some between Los Angeles, California and Las Vegas, Nevada and others between Los Angeles and Sun Valley, Idaho. For the first six months of operation, according to the Associated Press, Amtrak's best on-time performance was provided by Union Pacific which ran 94.2 percent of its trains on time.

Most of Union Pacific's former passenger car fleet, one of the best in the industry, has been sold. About 65 cars are being held for conversion to various types of company service cars.

Relief from the passenger train deficits had a favorable effect on net income in 1971 and is expected to have greater impact in future years. As reported to the ICC, losses solely related to Union Pacific's passenger service in 1970 aggregated $21 .2 million and on a fully distributed cost basis, $32.8 million. Establishment of a reserve to recognize the cost of joining Amtrak is discussed in the Financial Review on page 21.

May and June 1971
After most of the roundhouse work force in Ogden was either laid off or transferred to the Salt Lake shops in 1969, the roundhouse itself was used only to house and service the local switcher fleet. A series of dated photos furnished by Dean Gray show the demolition starting in May 1971, and continuing through June 1971.

All non-railroad properties transferred to Union Pacific Corporation. (Moody's, 1973 p. 511)

September 1971
Union Pacific formally completed its Little Mountain Branch, northwest of Ogden, serving the new industrial development complex northwest of Ogden, Utah, on the east shore of Great Salt Lake.

"Property Improvements - During the summer of 1971, construction was completed on the 13-mile Little Mountain branch line in Utah to serve new industries that will be locating at the Bear River Bay area of the Great Salt Lake. The Railroad was assisted in acquiring right of way property by Upland Industries. Service from Hot Springs, Utah was inaugurated in September to a large chemical processing plant, the first of several installations expected in the area." (Union Pacific 1971 Annual Report)

In May 1967, Great Salt Lake Minerals and Chemicals Corp. had begun building a large plant for commercial extraction of potassium sulfate, sodium sulfate, and magnesium chloride, along with common salt. The plant included 17,000 acres of evaporation ponds just north of Little Mountain, west of Ogden on the lake's eastern shore. (Peter Behrens, "Industrial Processing of Great Salt Lake Brines by Great Salt Lake Minerals & Chemicals Corporation", Great Salt Lake, a Scientific, Historical and Economic Overview, p. 223)

September 27, 1971
Little Mountain Branch Opened -- On September 27, the Little Mountain branch was opened for service. Approximately 13 miles in length, the trackage serves the Great Salt Lake Minerals & Chemical Corporation located on the shores of Utah's Great Salt Lake. (UP Info, November 1971; December 1971, with coverage of John Kenefick's visit to Utah)

October 1, 1971
John Kenefick became president of Union Pacific Railroad. He had returned to Union Pacific on May 1, 1968 as the railroads Vice President of Operations. He had previously worked for Union Pacific from 1947 to 1954, when he left for a position with D&RGW, then with New York Central until 1968.

December 1971
The following comes from the December 1971 issue of Pacific News:

New Unit Train -- In addition to Southern Pacific's ore trains from Eagle Mountain and Union Pacific's unit coal train from Utah, the U.P. has begun bringing in iron ore from the Standard Slag Company's mine at Beck, Ca. The ore is mostly magnetite with some hematite and will be sold to the Tonan Trading Company of Tokyo who are the agents for different Japanese steel mills. The 15-hour, 280-mile rail haul originates at Cima, California, where the ore is loaded into the train known as the "CUW" (Cima Unit West). The current schedule includes 8 hours for loading, 24 hours for unloading and four hours for servicing at Union Pacific's East Los Angeles Yard. Currently gondolas are in used with 55 new ore cars on special order for the service at a cost of about $900,000. Consist of the train on November 9th was SD24 #421, SD24B's 418B, 425B, 440B and GP9 #322. There are a planned 100 5000-ton shipments per year, to be unloaded at Berth 49 in San Pedro. (reported by Leon Callaway, Pacific News, December 1971, page 15)

Union Pacific removed the train sheds for the west side of the Salt Lake City depot. (Historic American Building Survey, by Utah State Division of History)

The Union Pacific depot at Layton was moved from the station grounds just south of the Gentile Street crossing, south about one-third mile to a new location. The building was turned 180 degrees so that the station agent's bay window faced east instead of west. Improvements were made and the building opened as Doug and Emmy's Restaurant.

The Layton depot building was originally located approximately 500 feet south of Gentile Street, on the east side of the tracks, as part of a large depot grounds, which included a local "team track" where railroad customers could load and unload freight shipments, as well as board and depart from passenger trains. The site is at 175 West Gentile Street and is still owned by Union Pacific Railroad. Layton City Parks and Recreation maintains the park at the site. First known as "Railroad Park" after the depot was moved, the site was special because of four large trees planted on Arbor Day, April 15, 1921, in honor of four Layton men who died in the Army during World War I. The site was dedicated as Veterans Park on Veterans Day (Nov.11th) 1991.

April 27, 1972
The North Temple Street viaduct in Salt Lake City opened for traffic, two months ahead of schedule. The viaduct took street traffic over Union Pacific and D&RGW tracks. Weyher Construction Company served as general contractor for the $3.5 million project that replaced a "narrow and dilapidated structure". Construction was said to have taken only five months. (Deseret News, April 27, 1972)

June 18, 1972
"Union Pacific Railroad has hit a public relations gold mine. The railroad which is taking delivery of 20 General Electric locomotives (U30C, 2810-2829) was named Customer of the Month of May by GE. The GE units are used to pull UP's "hot trains,' those that run on tight schedules to the West Coast. William J. Fox, UP's vice president of operations, sees the new locomotives as significant additions to the railroad's "We Can Handle It" program. The locomotives will be pulling primarily grain, fruit, automobile, containerized freight and piggybacks." (Pocatello Idaho State Journal, June 18, 1972)

July 1972
Union Pacific installed 7,843 feet of rock slide protection fences along its mainline in Weber Canyon, between Devil's Slide and Gateway. (UP INFO, July 1972)

July 15, 1972
Union Pacific, along with Burlington Northern and Southern Pacific, began operating a new train, called The Overland Mail to improve mail delivery by the U. S. Postal Service. (UP INFO, August 1972) (The new trains were symboled as OME and OMW, for Overland Mail East and Overland Mail West)

The following comes from the August 1972 issue of the UP INFO employees magazine.

It is 7:15 p.m. and the Overland Mail departs Council Bluffs on its run from Chicago to Oakland, California. The date? It's July 15, 1972, and one of the most illustrious names in rail-postal history is being revived.

The new fast mail train, running daily, eastbound and westbound, over the 2,000-mile route, promises up to three days earlier delivery of parcel post and bulk mail.

Officials of the U.S. Postal Service and the three railroads sharing in the operation of the train said that the new service will reduce westbound transit time from 58 to 50 hours and eastbound time from 71 to 50 hours.

The Overland Mail will carry approximately 15 per cent of the Postal Service's bulk mail volume. It runs over the Burlington Northern from Chicago to Council Bluffs, over Union Pacific from Council Bluffs to Ogden, and over Southern Pacific from Ogden to Oakland. Intermediate stops are made at Omaha, Cheyenne, Ogden, and Sacramento.

At these exchange points, other rail and truck routes will provide connecting service to six other mail distributing areas. They are Milwaukee, Minneapolis, Denver, Salt Lake City, Portland, and Los Angeles.

The new train is part of the U.S. Postal Service's program to improve its transportation network involving the utilization of trains, trucks and planes.

July 16, 1972
Union Pacific and Western Pacific started a new train serving the San Francisco Bay Area. "Designated AWPF (Advance Western Pacific Forwarder) and WPF (Western Pacific Forwarder), the trains operate from North Platte to the Western Pacific connection at Salt Lake City." (UP INFO, August 1972)

August 18, 1972
"Ogden By-Pass In Service -- On August 18, through South Central District trains began using the new by-pass trackage to move around Ogden's yard. The trackage is designed to help relieve congestion in the Ogden area." (UP INFO, September 1972)

The Ogden By-Pass track was reported as being 38 percent complete in July 1972, and was completed in late July 1972. The by-pass allowed South-Central District trains from California to by-pass the Ogden yard using a new track added along the west side of Riverdale Yard between Bridge Junction and East Riverdale, at the south end of Riverdale yard. This by-pass track did away with the congestion of mainline trains needing to cross the west (compass north) end of Riverdale to get to the double track mainline that was along the east side of the yard. The construction of the Riverdale By-Pass track, and the addition of CTC from East Riverdale to Strawberry in 1974, was an extension of the CTC territory that was already in place between Salt Lake City and Ogden at Bridge Junction. (UP INFO, July 1972)

The Ogden By-Pass track was shown in employee timetables for the first time in the Utah Division Employee Timetable No. 48, dated September 16, 1973. The by-pass track was not shown in timetable No. 47, dated May 1, 1972.

October 1972
Union Pacific rebuilt its tracks along Fourth West, between Second South and Ninth South, in Salt Lake City. The tracks were completely removed and new sub-roadbed was installed. New ballast, ties and heavier rail, including 6,000 feet of track and 23 new switches, were installed. The major feature was separating the track structure from the street structure with a curbing. Many of the original, but unused spurs were removed at the same time. The project cost $650,000, all at Union Pacific's expense, and was expected to be complete by the end of November. UP had 60 customers along the line. About six trains per day used the track, including the southbound iron ore train to Geneva Steel. The line was previously all double track. The new line included double track only between Fifth and Sixth South. (Deseret News, October 19, 1972)

October 25, 1972
Union Pacific formally donated 4-8-4 steam locomotive no. 833 to Salt Lake City in a ceremony in front of the locomotive's new home in Salt Lake City's Pioneer Park. The locomotive had been moved into place using a series of temporary panel tracks laid end-to-end from the railroad's line along 400 West. The move had taken place on October 23rd and 24th. The locomotive had been stored in Cheyenne, Wyoming since its retirement in 1962, and was offered as a donation to Salt Lake City in August 1972. (Deseret News, October 24, 1972, with a photo of UP 833 on 400 West; Union Pacific INFO, December 1972, page 13, with photos of the donation ceremony)

December 1972
Union Pacific completed the "one-spot" car repair facility in Salt Lake City. Construction was begun in July. The facility was the latest of many one-spot car shops being built all over the Union Pacific system, the first was at Council Bluffs, opened in early 1972. Total cost was reported as being $640,000. (Union Pacific 072772r news release; UP INFO, July 1972)

January 16, 1973
"Growth At Clearfield-Freeport -- A new railroad office building at Clearfield Freeport Center was opened on January 16, 1973. The new building combined the offices of UP, D&RGW, and the Western Weighing and Inspection Bureau. UP's offices had formerly been in UP's Clearfield depot. The offices of the other organizations had been in smaller buildings at the Freeport Center." (UP INFO magazine, February 1973)

March 2, 1973
"Salt Lake City One-Spot Opens -- March 2nd saw the opening of the new Salt Lake City one-spot car repair facility. The $640,000 installation is the second of seven planned one-spot plants to be placed in operation." (UP INFO magazine, March 1973)

The following comes from the April 1973 issue of Union Pacific's INFO magazine (UP INFO magazine, Volume 5, Number 5, April 1973).

New Era Of Freight Car Repairs, Salt Lake -- Maintenance of locomotives and cars has been undergoing dramatic changes on Union Pacific in recent years. The opening of another new one-spot gives us a good opportunity to make a comparison between the new and the old. Salt Lake City's one-spot will, as in Council Bluffs, replace the old rip track operation.

The opening of the Council Bluffs one-spot marked the beginning of UP's new era of freight car repair. The new Salt Lake City facility is the second such plant to be opened on Union Pacific property. Others are either planned or under construction at several locations on the system.

Traditionally, repairs to freight cars were performed by spotting the bad order cars on repair tracks. The car men would then take the necessary tools and materials to each car and then make the repairs. This system, at best, was inefficient.

In the "one-spot" operation, the cars are moved through well-tooled, well-stocked repair stations-in effect reversing the sequence of events by bringing the car to the repairman, his tools and materials. The new system is designed to achieve substantially increased efficiency and productivity and at the same time provide vastly improved work areas for the employees.

The Salt Lake City "one-spot" car repair facility consists of a 114 x 22-foot car repair service canopy with three tracks running the length of the structure. Two of the tracks are equipped with built-in jacking systems, jib cranes, air, lubricating oil, grease, gas for cutting torches and power for arc welding. All of these utilities are piped to each repair station.

A 30 x 170-foot shop building adjoins one side of the car repair service canopy, in which are offices, a carpenter shop, blacksmith shop, locker and washroom facilities.

October 9, 1973
There was a wreck involving a southbound freight train, on the curve in Draper, Utah. Motive power on the train was SD40-2 3190 in lead position, with the following units trailing: SD24B booster units UP 438B, 428B, 407B, 402B, and SD24 cab unit 424. (Extra 2200 South, Issue 41, July-August 1973, page 13, reported by Don Strack)

"UP -- At 7:30 a.m. 10/9/73, at Draper, Utah, SE of Salt Lake City, a northbound consist of 3190 SD40; 438B, 428B, 407B, 402B, all SD24B's and 424 SD24, all derailed except 3190."

November 1973
The following comes from the November 1973 issue of UP INFO magazine for employees.

Catenary Tests For Utah And Wyoming -- Two half-mile sections of electric catenary structures will be built in Utah and Wyoming to test the feasibility of electrifying part of UP's main line. (The catenary is the overhead structures and cables which supply power to electric locomotives.)

The first section will be built near Farmington, Utah, and will utilize a design developed in Europe. The second section of catenary scheduled for construction next spring, will be located at Emkay, Wyoming and will use American designed materials.

Although neither of the sections will be electrified for train operation, the Farmington site will be energized for interference tests. These tests will explore possible interference from the high voltage lines with other signal and communication lines.

UP has conducted extensive studies on the possible electrification of main line trackage from North Platte to Salt Lake City and Pocatello.


December 1973
Weber Industrial Park -- The following comes from the December 1973 issue of Union Pacific's INFO magazine for employees.

W.I.P. -- Newest On Line Station -- The newest station on the UP system was officially dedicated recently just outside Ogden, Utah.

Beneath a bright new sign which designates the station as "WIP," for Weber Industrial Park, railroad and Weber County officials shared in a traditional groundbreaking ceremony, using a plated and engraved shovel presented by UP traffic manager Bill Whalen to the Weber County Industrial Development Bureau for use in future groundbreakings for new industry in the industrial park.

The 475-acre industrial area was established by Weber County to attract new industry into the area. Upland Industries and UP railroad personnel worked closely with the county from initial planning sessions right through to final establishment of the park.

Buildings for one industry have been completed and three others are now under construction in the industrial park, as are roads, curb and gutters, water sewer lines, storm drains and other facilities. Spot tracks will be built as needed to serve industries that will require rail transportation. Officials expect traffic will eventually amount to 1,000 or more cars from industries in the park.

The Strawberry to Riverdale CTC territory was added in 1974 as a continuation of CTC control of the Riverdale By-Pass track, completed in September 1973. The addition of CTC through to Strawberry was an extension of the CTC territory that was already in place between Salt Lake City and Ogden at Bridge Junction, and the Riverdale By-Pass between Bridge Junction and East Riverdale.

January 1974
The balloon track at Ogden was removed. "Trackage is being rearranged and constructed in the Ogden area to facilitate movement of traffic between Pocatello and Salt Lake City. North-South traffic has previously moved around the Ogden Balloon Track when going through that terminal." (UP INFO magazine, January 1974, page 4)

February 1974
UP began using its eight unique SD40X locomotives, numbered UP 3040-3047, on the Atlantic City, Wyoming, to Geneva, Utah, iron ore unit train for U. S. Steel. The eight units replaced similar sets of SD24s and SD24Bs. (Extra 2200 South, Issue 43, November-December 1973, page 12, reported by Don Strack)

February 18, 1974
Union Pacific announced plans to demolish the wooden depot building at Cache Junction. The 1300 square-foot building was to be replaced by a easy-to-heat metal trailer. The adjacent cafe had received a notice that its lease was to expire on April 1, 1974. (Deseret News, February 18, 1974)

Late 1974
Union Pacific completed expansion of Salt Lake City diesel shop, including construction of the new locomotive servicing facility. Construction was begun in March 1973. (Union Pacific news release, dated March 27, 1973) The construction of the locomotive servicing facility and the "one-spot" car repair facility required removal of the old rip track and old coach yard.

The TOFC piggyback ramp at Salt Lake City was of the drive-on type until 1975, when they received their first "Piggy-Packer."

Union Pacific reopened the Aspen tunnel in Wyoming. The tunnel had been closed for 18 months as UP completed a $6,000,000 project to enlarge the tunnel to allow oversize loads. (UP INFO magazine, Volume 8, Number 2, January 1976)

The Aspen tunnel had been completed in 1901 as part of a line change that replaced the steep and twisting Piedmont Hill, built in 1868. Work on the Aspen tunnel had begun in November 1899. Work on the Aspen tunnel's companion tunnel, the Altamont tunnel, as Union Pacific's longest tunnel was begun in spring 1947 and was completed in November 1949. Prior to the opening of the Altamont tunnel in 1949, the Aspen tunnel had been a single-track choke point for an otherwise double-track railroad.

"When part of the mountain fell into a valley at about 7 a.m. on March 19 at Uintah, Utah, it buried both east and westbound main lines. In at least one area, though, fortune was on the side of UP. It occurred near a place where a contractor was working with large earth moving equipment. Using this equipment to clear the way, the westbound main was back in service by 12:30 p.m. The eastbound line opened to traffic again by 11:30 that same night."

Union Pacific received Utah Public Utilities Commission approval to abandon portions of the Ironton Branch. (Public Service Commission of Utah, case 77-400-06)

During late 1977 Union Pacific received ICC approval to abandon the loop track at Cedar City. With the abandonment and removal of the loop track, the Cedar City depot building was sold to a local developer. Passenger service to Cedar City ended in 1960, but UP still provided freight service to Cedar City, and would move its team track and freight tracks north to Third West street. (Salt Lake Tribune, July 23, 1977, "by the end of the year")

UP sold the Cedar City depot and surrounding property "last fall." The new owners removed the rail and ties during February 1978. (The St. George Daily Spectrum, February 26, 1978)

A westbound freight train carrying hogs to Los Angeles, collided at Lakepoint with a set of two locomotives and a caboose that had gotten away from Warner, Utah.

UP 3336, 3375, and 3353, along with UP 3071 and 3146, were all involved in a wreck at Lakepoint , Utah, on August 19, 1977. UP 3336, 3375, and 3353 were the power on the westbound CLS, when it was hit head-on by a light set of road power, with caboose, that were rolling east as a runaway that started at Warner. The runaway power was UP 3071 and UP 3146, along with UP caboose 25652. UP 3071, 3146, and 3336 were destroyed, along with the caboose. UP 3375 and 3353 were sent to Omaha for repair. Estimated loss of $1.3 million to company property was $1.3 million, along with $700,000 loss to cargo (hogs). (CTC Board, September 1977, page 7)

UP 3353 and 3375 were returned to service after repairs at Omaha. (Pacific News, October 1977, page 20)

A later report shows that the three destroyed units (UP 3071, 3146, 3336) were not scrapped on site, but were instead sent to Omaha in gondolas for damage assessment and possible removal of usable parts. (Pacific News, November 1977, page 17)

October 29, 1977
Utah Department of Transportation invited bids to relocate the Salt Lake Garfield and Western to a route adjacent to the UP and WP between 9th West and approximately 40th West. This would move the SLG&W tracks away from the proposed alignment of Interstate 80. (Salt Lake Tribune, October 29, 1977)

"New Salt Lake Offices -- Union Pacific Railroad has obtained a one-story brick building from Upland in Salt Lake City. The building, located next to the UP depot, formerly housed a Post Office annex. The building will be converted into office space for railroad personnel presently housed in a downtown building and for some now in the depot. Bids for remodeling are expected to be obtained in January, with construction probably starting in early spring of next year." (UP INFO, December 1977)

During mid October 1978, Union Pacific operated its 1944-built 4-8-4 steam locomotive, numbered UP 8444, from Cheyenne to Salt Lake City. The occasion was UP's donating Ogden Union Station to the City of Ogden. A special dedication ceremony was held in Ogden on October 21, 1978, and the locomotive returned to Cheyenne. The actual sale of Ogden Union Station to Ogden City took place in early 1977, with renovation by the city taking place over the following time period prior to the October 1978 dedication.

March 1979
UP's "Project K" was a proposal for a 200 mile rail line from the coal rich Kaiparowits Plateau in southern Utah, to the UP mainline in southwestern Utah. A proposed northern route was from the UP at Cedar City, south into Arizona, then northeast to the Plateau. Estimated cost ranges from $316.7 Million to 349.8 Million and would be the largest project of its type in the U.S. in fifty years. Sponsor for the coal field development was Southern Utah Coal Resource Group, a consortium of coal, utility, and transportation companies. To meet the proposed schedule, construction on the railroad portion must start early in 1983. Development was being sought for three major reasons: first, in anticipation of coal fired power plants in Southern California, replacing oil and natural gas installations that depend on energy resources that were becoming scarce; second, for possible exports to Japan; and third, to ease pressures on existing Utah, Colorado, and Wyoming resources.

Union Pacific began the demolition of the Milford depot. The following comes from the June 4, 1981 issue of the Beaver County News of Milford, with photo:

There were a lot of old weathered Railroaders around when the huge backhoe of A .J. Mackay Co. began biting into Union Pacific Depot at Milford. It was almost anticlimax, since the announcement on Friday, March 13th that the historic old Spanish architecture would be demolished. Milford came to arms. Milford City and the Milford Historical Society took measures to try to save the building. A restraining order was obtained, but alas, there was no solution. Having exhausted every legitimate recourse, the city dropped their charges, rather than to delay, just for the sake of delay. But still the building didn't come down.

The Union Pacific presented a plan for the new office building to replace the old Depot, using the Spanish architecture. The Friday the 13tn nightmare became a reality Tuesday, June 2nd, when A.J. Mackay Co. started knocking it down. It should be leveled in 24 hours at the rate of demolition. Then the cleanup begins. It is expected to be completed within two weeks. Then hopefully the new construction will get underway as soon as possible.

[photo caption, June 11th issue] Demolition of the Milford Depot started Tuesday, June 2nd and by June 3rd it was just a heap of rubble. Cleanup is progressing at a rapid pace, and all the rubble should be hauled and buried in another week. Picture shows huge backhoe poised over the final wall before it came crumbling down. Spectators lined the street all through the demolition, watching as the majestic Spanish structure came down bit by bit. The Union Pacific plans to build a new office building in its place, using similar architecture.

[photo caption, June 11th issue] The last thing to fall was the smoke stack, over seventy feet tall. After notching one side, the big backhoe just nudged it, and down it came. Milford has lost its most beautiful landmark.

Milford Depot Demilition. The following comes from Arden Fowles, Milford City Secretary:

The Beaver County News followed the demolition of the Milford Depot during the first week of June 1981. The demolition was started on the 2nd of June and took just a few days to complete. The newspaper had a page of demolition photos in its June 11th issue. (Arden Fowles, Milford City, email dated January 16, 2003)

Milford Depot Demolition. The following comes from John Bromley, Director of the Union Pacific Museum, Council Bluffs, Iowa:

The old Milford depot was torn down in 1981 and replaced with a new "Spanish style" depot amid great ceremony. The towns people had raised hell about their beloved station being razed and the railroad went to extensive effort to smooth feathers with a modern replacement. I think it was the last "new" depot for UP, although basically it was a yard office. I was there as the regional PR representative for UP the ribbon-cutting on October 1, 1982. (John Bromley, Trainorders.com, March 15, 2008; with photo of new depot)

"Coal to Valmy -- Unit coal trains handled by Union Pacific and Western Pacific began making deliveries July 2 to a new power plant located in north-central Nevada which will begin generating power this fall for northern Nevada and southern Idaho. Coal for the North Valmy Generating Station comes from the Sharp, Utah area via UP to Salt Lake City where it is handed off to WP for final delivery. A 65-car train which UP handed off to WP July 2 was the first unit coal train ever handled by WP. Three-time weekly deliveries now are building up the coal supply at the Valmy station which will always have a 90-day supply on hand." (UP INFO, July-August 1981)

Union Pacific tore down the Provo "Joint Shop Facility" that was shared with Utah Railway. The building was a large two-track steel structure with numerous windows, an interior overhead crane, and large jacks that could raise a locomotive. It was the last remaining structure of the former joint locomotive facility owned by UP and Utah Railway that had included a roundhouse, turntable and coaling station, all built in 1917. The backshop, 75 feet by 240 feet, was built in 1920, with a formal completion date of January 25, 1921.

Salt Lake City became the 1,000-mile inspection point for Union Pacific. "What year did we go from a 500 mile inspection to the 1000 mile?"

The FRA rule that called for 500-mile inspections was 49 CFR 232.12(b).

According to a very long Federal Register web page from September 1994, the rule was changed in 1982 to allow 1000-mile inspections. "In the 1982 revisions to the power brake rules, FRA extended the distance between these inspections from 500 miles to 1,000 miles."

Here is the rule as it currently reads...

"Trains must receive an intermediate inspection at points not more than 1,000 miles apart. It is the carriers responsibility to designate the points where the 1,000 mile inspection will be made and provide this information to FRA personnel upon request. All mileage accumulated from the point of the initial terminal air brake test will count toward the 1,000-mile requirements in Section 232.12(b). It should be noted that mileage accrued in Canada and Mexico will count toward the 1,000-mile requirements. When cars are received in interchange, the receiving railroad is responsible for knowing the distance that all of the cars have traveled since their last inspection."

Union Pacific announced the installation of Centralized Traffic Control (CTC) on the Provo Subdivision south from Provo to Lynndyl. (Union Pacific press release dated September 8, 1982)

UP announced that work is well under way on installation of a Centralized Traffic Control (CTC) system on UP's coal line from Provo south to Lynndyl. The 87-mile connection from Provo to UP's main line at Lynndyl will then have an electronic signal system similar to the system already in use on the Ogden-Salt Lake City- Los Angeles main line. Because of the remote location of much of the Provo line, solar energy will be used to power many of the signals where commercial electricity isn't available. The CTC system is expected to be operational early in 1983. The $6.1 million CTC system will give the Provo line extra capacity and will increase train operating flexibility by providing remote control of switches and trackside signals from a CTC panel to be located in the Salt Lake City dispatching center.

(The new CTC went into service in time for the Union Pacific employee timetable No. 7, dated June 12, 1983.)

October 1982
Salt Lake City CTC Building. The following comes from the October 1982 issue of UP INFO for employees.

CTC building underway -- Construction on Union Pacific's new $3.7 million dispatching and communications center began in late September in Salt Lake City.

Being built adjacent to the existing dispatchers' office, the new building will house equipment and provide work space for dispatchers who will operate the new Centralized Traffic Control system now being installed on the railroad's Provo Subdivision.

The existing dispatchers' office will be expanded and remodeled.

Located a short distance north of the UP Depot, the new dispatching- communications structure will have the same exterior appearance as the existing district office building immediately south of the depot.

South Central District General Manager R. E. Irion said the construction will give visual balance to the entire UP complex.

Installation of Centralized Traffic Control (CTC) on UP's coal line from Provo south to Lynndyl is well underway.

The 87-mile connection from Provo to UP's main line at Lynndyl soon will have an electronic signal system similar to the system already in use on the Ogden-Salt Lake City- Los Angeles main line.

Because of the remote location of much of the Provo line, solar energy will be used to power many of the signals where commercial electricity is not available.

The new communications building is scheduled for completion in March of 1983 while the CTC system is expected to be operational in early 1983.

The $6.1 million CTC system will give the Provo line extra capacity and will increase train operating flexibility by providing remote control of switches and trackside signals from a CTC panel to be located in the new Salt Lake City dispatching center.

December 1982
Morgan Depot Donated. The following comes from the December 1982 issue of UP INFO for employees.

Depot donation -- Union Pacific Railroad donated its 54-year-old Spanish style depot at Morgan, Utah, to the City of Morgan December 1. The building, a local landmark, was built in 1926 by Ryberg-Sorenson, Inc. of Salt Lake City at a cost then of $13,601. It has hollow tile walls on a concrete foundation, exterior walls of stucco with a brick trim and a roof of mission tile. The interior waiting room features exposed wood beams and Douglas fir trim.

A safety fence will be installed between the station and Union Pacific's nearby main line tracks.

Due to computerization of sales functions at regional centers, Morgan area shippers now deal directly with UP representatives in Ogden, 24 miles west of Morgan. The city plans to use the building for various city functions.

January 1, 1983
Union Pacific control of Western Pacific Railroad took effect. UP had received federal ICC approval for its control of WP and MP on December 22, 1982.

(Read more about WP in Utah prior to January 1983)

In 1983, after their recent merger, and with the common ownership of both UP and WP lines west of Salt Lake City, the need no longer existed for WP-UP Junction at 1100 West in Salt Lake City. The junction had been put in place in 1967 as part of the 15 miles of joint operations between Salt Lake City and Smelter (15 miles to the west), to allow WP trains to crossover to WP-owned tracks before the ownership changed at the Jordan River. WP-UP Junction was removed and the double crossover was moved several miles west to Orange Street, about a mile west of Redwood Road.

January 18, 1983
Provo to Lynndyl Microwave System. The following comes from the January 18, 1983 issue of the Provo Daily Herald newspaper.

Union Pacific Installs Advanced Microwave System -- A $9.8 million Union Pacific Railroad project to install microwave, signals and build a new communications center is 85 to 90 percent complete, according to a company spokesman. Begun last fall, the project includes installation of a microwave linked signal system from Provo to Lynndyl along an 87-mile stretch of track south of Provo.

Union Pacific expects the new microwave system to increase line capacity to meet the projected growth in export coal traffic. A $3 7 million communications center, which will handle train dispatching from Salt Lake City to Los Angeles, is being constructed in Salt Lake City.

The Centralized Traffic Control (CTC) and automatic block signals being installed on the line south of Provo will give the single-track route about 80 percent of the capacity of a double-track railroad, Union Pacific officials say. Additional sidings and a centralized switching center will allow trains running in opposite directions to safely use the single track, according to Union Pacific.

Switching will be done by microwave from the new communications center. Dispatchers will follow train movements through lights on a schematic display map indicating their progress. By pushing buttons on the console panel, dispatchers can send coded signals along the route.

Electric motors on track switches will then switch trains in and out of sidings without them having to stop. Color signals along the track will alert train engineers to the dispatcher's actions.

Some locations in remote areas will have signals powered by panels and batteries.

The CTC and the communications center are expected to allow faster and more flexible train operations, permitting more trains to be operated on the line in a given time period.

February 1983
Salt Lake City CTC Building. The following comes from the February 1983 issue of UP INFO for employees.

CTC building rises -- Construction of UP's new Centralized Traffic Control Building in Salt Lake City, Utah, is well underway. Workers began building the roof during the first week of February following completion of footings and foundations and the laying of concrete block walls. Underground plumbing and electrical work also are underway.

The building, which will require $2.2 million in 1983 funds, will house dispatchers who will direct CTC on the South Central District, including new CTC being installed on the Provo Subdivision.

Dispatchers are scheduled to be moved to the new building in July, but some phases of the new CTC installation will not be completed until 1984.

WP UPgrades. "...raising the north track adjacent to the Great Salt Lake in Utah, from Mile Post 899 to 910, and the south track from Mile Post 895 to 912, will be completed this month. As of September 28, 833,824 cubic yards of material had been dumped to raise the track, protecting it from the ever-growing Great Salt Lake, bloated by heavy rains and runoff from the mountains. Work to raise the flooded former WP track above water in the usually dry Bonneville Salt Flats in Western Utah has been completed." (UP InfoNews, September 1983)

October 1983
Western Pacific Upgrade. The following comes from the October 1983 issue of UP InfoNews for employees.

Western District track work update -- As of September 1, 580,000 cubic yards of fill were in place to protect the Western District track from Mile Post 899 and Mile Post 910, where washouts were occurring from wave action from the bloated Great Salt Lake.

In the first phase of the work, a 35-foot beach is being built along the 11-mile stretch of track, to be completed in early September.

Phase two will begin shortly thereafter, and will include raising and surfacing the track, as much as 39 inches in places. This work is scheduled to be complete by the end of this month.

Also by the end of the month, the main line rail relay program from Sacramento to Marysville will be finished. The 12-mile relay program in the Feather River Canyon was completed in late August.

Curve relays on the Western District were about one-third done in early September and work to install 57 miles of new sidings between Garfield, Utah, and Hayward, California, is scheduled to begin October 1.

UP removed the short test installations of catenary at Farmington, Utah, and Emkay, Wyoming. These had been installed during the early 1970s to test the two most feasible designs of catenary for electrified locomotive operations. (Extra 2200 South, Issue 81, July-August-September 1984, page 15)

WP Repairs. The following comes from the May 1984 issue of UP InfoNews, for employees.

On the rise -- As of late April, the saga to keep UP track above water at the Great Salt Lake continued. Between March 15 and April 16, the water level rose 10.2 inches, as much in 30 days as in any period in recorded history.

The lake level April 16 was 4,207.75 feet above mean sea level, the highest since 1879. In late April, the area was still receiving snowstorms.

Three phases of the work to keep UP track out of water's reach by building a beach were completed in April and the track was still being raised. The Engineering Department is studying four more phases, each designed to raise the track another foot.

With local experts predicting the water level to be 4,212 feet by April of 1985, engineering studies recommend raising the beach to an elevation of 4,216 and the track to 4,218 feet. This would require an additional 1.6 million cubic yards of material.

June 11, 1984
Union Pacific (LA&SL) received ICC approval to abandon the Fillmore Branch from Delta (Mile Post 0.5) to Fillmore (Mile Post 32.26).

The coal was to in 84-car trains originating in Utah County, where it was to be interchanged from D&RGW and Utah Railway from mines in Carbon and Emery counties. IPA had signed six contracts with coal suppliers in Utah to furnish the cola needed when the power plant goes on-line in late 1986. (Salt Lake Tribune, June 26, 1984)

Salt Lake Peaks -- The Great Salt Lake berm project is nearing completion, at least for now. The UP track, from Smelter at Mile Post 897, has been raised eight feet, to 4216 above sea level, since January, 1984.

Water continued to rise throughout the spring, caused by record snowmelt and rain. According to Paul Armstrong, engineer of track, the lake's level peaked June 30 at 4209.25 above mean sea level. However, the lake now has begun its evaporation stage, which normally occurs between June and September.

As of August 1, the lake fell to 4209.05, the first decline in nearly a year. Armstrong said the lake could decline another six to 12 inches, because the Southern Pacific causeway was breached August 1. A trestle will span a 300-foot hole in the causeway.

More than 55,000 carloads of material have been dumped on either side of the track since July 1983. A 35-foot beach on the lake side will protect the track from future wave action.

Wave action between Interstate 80 and UP track on the south side prompted the construction of a 13- foot shoulder, said Armstrong.

Crews should complete the $16 million project by mid-August.


October 7, 1984
Union Pacific's first official cabooseless train left westbound out of Salt Lake, City, Utah. The train was a double-stack container train for American President, Lines. The substitution of an end-of-train device for the caboose was the beginning of the end of caboose operations on UP. Within a week, cabooseless operations began in all directions from Salt Lake City, and within a month, cabooseless operations began in all directions from Cheyenne. Cabooses were required on trains in the Northwest until September 1985, when the State of Oregon allowed the operation of cabooseless trains. Down on the former Missouri Pacific lines in Texas, cabooses were required on all trains until November 1989. There were still 740 cabooses in use by Union Pacific when that first cabooseless doublestack train went west out of Salt Lake City. 

December 1984
High Water on the WP. The following comes from the December 1984 issue of UP InfoNews for employees.

Water everywhere -- The Great Salt Lake is on the rise again and water experts predict that by mid-1985 it might exceed last July's 106-year record level.

The development is of interest to UP System construction engineers who have successfully kept 15 miles of endangered trackage high and dry, despite the lake rising almost steadily for more than two years.

Following a July 1 peak of 4,209.25 feet above mean sea level, the Salt Lake fell due to evaporation and the breaching of a Southern Pacific Transportation Company causeway. But the lake began its annual wet season rise October 7.

State and national water experts said the summer evaporation was considerably less than usual, fueling predictions of much higher levels this winter and during next spring's mountain run-off.

The July 1 peak was the highest since 1878 and the experts say it's possible the 1985 level will exceed that as well as the lake's highest level in recorded history—4211.5 feet in 1873.

Such levels would threaten two interstate highways, several salt companies, a sewer improvement district, a Utah Power & Light Company transmission line and an industrial waste lagoon.

Early 1985
Union Pacific placed a "Piggy-Packer" in service at the intermodal ramp in Salt Lake City. The new machine included weigh-in-motion capability. Trailer-On-Flat-Car (TOFC) traffic for UP at Salt Lake City had doubled since 1982. (Pacific RailNews, Issue 257, April 1985, page 5, from Railway Age)

Spring 1985
U.S. Steel's Iron Mountain mine on UP's Cedar City/Iron Mountain Branch was closed in 1983, along with the Atlantic City, Wyoming, mine. U.S. Steel's Geneva Works were furnished with taconite from Minnesota. The Iron Mountain mine reopened in spring 1985 to furnish the new Geneva Works, with about two unit trains running per week. (CTC Board, July 1985, page 14)

April 21, 1985
The former Union Pacific depot in Park City was heavily damaged by an arson-set fire. (Deseret News, April 22, 1985)

May 1, 1985
Union Pacific closed it sales office in Salt Lake City. The office was located in the north end of the UP depot at 400 West South Temple. (Deseret News, April 2, 1985)

October 22, 1985
Union Pacific and D&RGW exchange trackage rights on each others lines between Ogden and Salt Lake City (D&RGW operating on UP), and between Salt Lake City and Provo (UP operating on D&RGW). (CTC Board, December 1985, page 43, reported by Ryan Ballard)

At the same time, UP and D&RGW removed the angled crossing at Lakota Junction, near Orem, and replaced it with a switch that allowed UP trains direct access to the D&RGW mainline to Salt Lake City. (James Belmont, March 19, 2005 email to Trainorders.com)

(Read more about the Lakota Crossing; on the D&RGW 1908-1988 page)

November 1985
Mines in Iron Mountain region were independent. By summer 1984 all machinery at the mines had been sold to various gold mines developing in Nevada. In January 1985 UP was considering total abandonment of the 31-mile Cedar City Branch, along with the connecting 14-mile Iron Mountain Branch. In April 1985, just after UP had informed U.S. Steel of its intention to abandon the branches, U.S. Steel let UP know that they were considering reopening the mines to furnish ore to the Geneva Works. By June 1985, one mine had reopened and was furnishing ore to the Geneva Works. Mine owned and operated by Gilbert Construction Co. of Cedar City, Utah. Trains being operated were the SUW (Steel Unit West) empties and the SUE (Steel Unit East) loads; on a one train per week schedule. A summary of operations included information that Gilbert Construction Company (of Cedar City, Utah) was the new operator of the Iron Mountain iron mines, plus operational notes that Union Pacific picked up loaded iron ore cars on Thursdays at 4 p.m. The main iron mine was at Comstock. Other iron ore loading facilities were at Iron Springs, Deseret, Mound, and Iron Mountain. (CTC Board, November 1985, pages 49-50)

January 1986
Union Pacific announced that all customers along the Wyoming-Ogden main line in Utah, together with customers on the Park City Branch and Ontario Branch, will be served by a toll-free customer service number in Salt Lake City. The stations served include Ogden, Baskin, Castle Rock, Devils Slide, Echo, Emory, Henefer, Morgan, Peterson, Strawberry and Uintah on the main line and Calgas, Coalville, Keetley Junction, Park City, Wanship, and Phoston on the branches. (Union Pacific news release, dated January 1, 1986)

January 13, 1986
Union Pacific (OSL) received Utah Public Utilities Commission approval to close the agency at Logan, on the Cache Valley Branch. (Public Service Commission of Utah, case 85-400-02)

January 13, 1986
Union Pacific (OSL) received Utah Public Utilities Commission approval to close the agency at Brigham City. (Public Service Commission of Utah, case 85-400-02)

April 29, 1986
The Utah Division was eliminated. The new Western Region covered everything west of Green River, Wyoming, and was made up of the new California Division, Idaho Division, and Oregon Division.

May 5, 1986
Grant tower in Salt Lake City was closed. The facility controlled the crossing of D&RGW's double track mainline between Roper (Salt Lake City) and Ogden, and UP's ex LA&SL mainline, and WP's line to Oakland. There were at times up to 80 movements per day through the tower trackage. Control was taken over by two screens on the D&RGW dispatcher's station in Denver. (CTC Board, May 1986, page 12)

(See CTC Board, June 1986, page 6, for information about UP's battle against the Great Salt Lake during the spring of 1986.)


December 29, 1987
The Des Chutes Railroad in Oregon and the Oregon-Washington Railroad & Navigation Company were both merged into the Oregon Short Line Railroad.

December 30, 1987
The Oregon Short Line Railroad was merged into the Union Pacific Railroad.

December 31, 1987
The Los Angeles & Salt Lake Railroad was merged into the Union Pacific Railroad. The one day delay was necessary because the LA&SL was owned by both the OSL and the Union Pacific. The OSL was merged into the Union Pacific on December 30. Also on December 31, the Spokane International Railroad was merged into the Union Pacific Railroad.

June 1, 1989
The new Harriman Dispatching Center in Omaha began operations by taking control of the Seattle to Hinkle portion of the railroad. Control of the remaining parts was to take place over the following 15 months. (Pacific RailNews, Issue 308, July 1989, page 7)

The following was part of the online timeline at UP150.com, for Union Pacific's 150-year anniversary, celebrated throughout the summer of 2012:

Harriman Dispatching Center Opens -- Originally a freight depot, and the site where Union Pacific was sold out of receivership in 1897, the Harriman Center is the heart of train operations. Each day, it coordinates movement of more than 800 trains over more than 32,000 route miles. More than 750 people are employed at the facility, including those in “The Bunker” who monitor every switch and signal track on UP’s lines. The 1989 opening effectively centralized operations for the railroad, bringing together 10 regional dispatching centers from around the country.

July 27, 1989
The new Harriman Dispatching Center in Omaha was officially dedicated. (Pacific RailNews, Issue 311, October 1989, page 13)

After the Harriman Center opened in mid 1989, the Salt Lake City dispatching center was closed. The building was located just to the north of UP's passenger station, on the southwest corner of North Temple street and 400 West. The entire LA&SL, that part of Union Pacific between Salt Lake City and Los Angeles, including all of the LA basin, was dispatched from Salt Lake City, until June 1989 when the new Harriman Center opened in Omaha.

October 18, 1989
Union Pacific donated its Salt Lake City depot to the State of Utah, at a ceremony and dinner attended by Michael Walsh, Union Pacific president; Drew Lewis, Union Pacific chairman, and Utah governor, Norm H. Bangerter. (Deseret News, October 19, 1989)

May 1991
Union Pacific demolished the turntable that was part of the Provo Joint Shop, shared with Utah Railway. James Belmont wrote, "By 1991, it was difficult if not impossible for the railroad to find parts to repair it, and the decision was made to scrap it."

October 9, 1991
Union Pacific's depot in Salt Lake City became a landmark for many additional residents of the city and county with the formal dedication of the Delta Center, a new 20,000-seat arena that was located across the street from the depot.

December 31, 1992
ICC approved UTA's acquisition of UP's Provo Sub between 900 South in Salt Lake City, and Mount, at the line between Salt Lake County and Utah County. (ICC Finance Docket 32186)

March 31, 1993
Union Pacific sold a portion of its right-of-way between Salt Lake City and Provo to the Utah Transit Authority as part of its planned operation of light rail along the Wasatch Front. The actual trackage and railroad right-of-way involved includes the former Union Pacific route from 900 South in Salt Lake City south to the county line between Salt Lake County and Utah County. UTA also purchased the rights to first refusal on the UP line from the county line south to Lindon, Utah, in Utah County. Also included in the sale to UTA was the Dahl Spur, which runs west from the former UP tracks, under the Southern Pacific (former D&RGW) tracks and Interstate 15, to the west side of Midvale, at the former location of the abandoned smelter of the United States Smelting, Refining & Mining Company, later known as Sharon Steel Company. UTA acquired this trackage because of the existing access under the Interstate, saving them from having to fund such an underpass in the future. There was also some existing rail business at the end of the spur. To ensure continuous and seamless freight service to those customers, UTA negotiated an operating lease for its new rail property with Railtex Corporation, an operator of small, shortline railroads nationwide. The Railtex operating lease went into effect concurrent with the March 31, 1993 sale of the UP line to UTA. (Telephone conversation with Bruce Barnes at Utah Transit Authority, August 1994.)

May 1993
UP set up a concrete tie facility in Ogden. Quoting Pacific RailNews, issue 356, July 1993, page 49:

A major manufacturer of concrete ties, CXT Inc. of Spokane, Washington, announced the signing of a six-year contract with UP. During this period, 50 percent of CXT's annual production will go to UP. Approximately one-third of this total will be used in the UP track expansion programs on the Marysville Subdivision in Kansas and Nebraska plus the Blue Mountain project in Oregon. CXT will establish a shipping depot in Ogden, Utah, where the concrete ties will be stockpiled for delivery.



August 3, 1995
UP and SP announced on August 3, 1995 that they intended to consolidate their operations and merge. In Utah, both Geneva Steel and Kennecott Utah Copper were concerned that the new rail-monopoly in the state would result in increased rates. Geneva shipped about 70 percent of its finished products by rail, using either UP or SP. UP has agreed to allow a second railroad to have access to serve companies that were once served by both railroads, but following the merger, would be only served by the new merged company. At the time of the proposed merger, SP operated 564 miles of route in Utah, with 300 employees, and UP operated 859 miles of track in Utah, with 1,500 employees. (Ogden Standard Examiner, August 21, 1995, p. 4A)

The following comes from the October 1995 issue of CTC Board, page 10:

The Octopus Gets Swallowed UP ... For avid followers of the SP, the unthinkable was announced on August 3, 1995 when the Union Pacific announced that it was going to acquire the Southern Pacific. Even as late as a year or two ago, such a union would have been unthinkable, but with the recent acquisition of the C&NW by the UP and the BN/SF merger approved recently, it seems anything is possible now.

The merger would save the two railroads approximately $500 million a year through reduced costs, much of which will come through reduced employee ranks. While about 20 percent larger in track miles than the SP, the UP has about 35 percent more employees than the SP. The UP announced that it will spend about $500 million upgrading the SP with new track and equipment.

Some of the areas where this money may be spent are replacing the double track on the Overland the SP has been pulling up in the last two years; Double-tracking the Sunset Route from Los Angeles to at least El Paso; expansion of the West Colton Yard and the closure of the UP yard at Yermo; putting in a connecting track from the eastbound SP to the southbound Santa Fe track at Colton; double-tracking the Tehachapis; and building a central locomotive repair shop somewhere in the Los Angeles area. It will be interesting to watch and see in what priority these things will come about with the UP.

The UP would achieve great savings in transit time by combining certain SP routes with the business they already have. The SP route from Portland to the San Francisco Bay Area and to Los Angeles is much shorter, likewise from Los Angeles to all points in Texas, and the SP's Overland Route from Ogden to the Bay Area is faster. The SP would benefit by combing UP trackage with its own between Los Angeles and Sierra Blanca, Texas for Dallas and Memphis traffic, and traffic rights the SP will receive from the BNSF merger between Texas and the Wyoming coal fields will certainly see stiff competition.


September 11, 1996
Union Pacific received federal Surface Transportation Board approval to control Southern Pacific Rail Corporation (formerly Rio Grande Industries), including its Southern Pacific and Denver & Rio Grande Western subsidiaries.
