Chicago & North Western Railway

Union Pacific was granted control of Chicago & North Western on March 9, 1995 (other sources show April 12, 1995 as the date of control).

UP bought majority control of C&NW on April 25, 1995. The effective date of the approval for control was May 1, 1995. UP had purchased minority control of C&NW on December 13, 1994.

On August 1, 1995, UP merged with the former C&NW subsidiary Western Railroad Properties (WPRI) which C&NW had organized to build into the Wyoming Powder River Basin.

On October 1, 1995 C&NW was formally merged with UP.


May 6, 1994
C&NW's parent company's name was changed from Chicago and North Western Holdings Corporation to Chicago and North Western Transportation Company, effective May 6, 1994. The company's stockholders approved the change on May 3, 1994. The company's wholly-owned railroad subsidiary, Chicago and North Western Transportation Company was re-named Chicago and North Western Railway Company. During February of 1994, the Company's intermediate holding company subsidiaries, Chicago and North Western Acquisition Corporation and CNW Corporation, were eliminated by merger. (SEC, C&NW Form 10-Q, dated May 13, 1994)

March 7, 1995
The federal ICC approved Union Pacific control of C&NW. The decision became effective on April 6, 1995.

March 9, 1995
Chicago and North Western Transportation Company agreed to be acquired by UP Rail, Inc., a subsidiary of Union Pacific Corporation, in a transaction in which UP Rail would acquire 100% of Chicago and North Western Transportation Company outstanding shares of common stock not already owned by Union Pacific Corporation. (SEC, C&NW Form 10-Q, dated May 16, 1995)

March 16, 1995
The respective boards of directors of Chicago and North Western Transportation Company and Union Pacific Corporation unanimously approved and executed a definitive merger agreement. (SEC, C&NW Form 10-Q, dated May 16, 1995)

March 23, 1995
UP Rail initiated an offer to acquire the entire equity interest in Chicago and North Western Transportation Company. (SEC, C&NW Form 10-Q, dated May 16, 1995)

April 25, 1995
The sale of C&NW to UP was finalized, which resulted in Union Pacific owning approximately 99.5% of the shares. Trading of Chicago and North Western Transportation Company's common stock on the New York Stock Exchange was suspended on the same date. (SEC, C&NW Form 10-Q, dated May 16, 1995)

Total purchase price of control was shown as $1,103,544,610.00 for a total of 31,529,846 shares, which together with another 12,835,304 shares that UP Corp., already owned, gave UP a full 99.47 percent of outstanding C&NW stock. (SEC, C&NW Form 8-K, dated April 26, 1996)

CNW (formerly the nation's eighth largest railroad) was located in the central transcontinental corridor, consists of more than 5,300 road miles, employs more than 6,100 people and is a major transporter of coal, grain and intermodal freight. For the year ended December 31, 1994, CNW had operating revenues of $1.13 billion, net income of $84 million and assets of $2.22 billion. (SEC, Union Pacific Form 10-Q, dated August 14, 1995)

May 1, 1995
CNW's financial results were consolidated into Union Pacific Corporation effective May 1, 1995. C&NW employees started answering the phone as Union Pacific, and the cut-over of C&NW lading and billing information to UP's TCS was started. (part from SEC, Union Pacific Form 10-Q, dated August 14, 1995)

The first C&NW locomotive was renumbered to its new UP number on June 16, 1995, when C&NW 8699, a GE C44-9W, was renumbered to UP 9668. Others followed soon after on June 23 and June 24, 1995. (Union Pacific, Mechanical Department records)

July 5, 1995
UP and former C&NW operating departments were realigned and consolidated, creating three new service units on former C&NW territory. These three new service units were: Twin Cities Service Unit, headquartered in Minneapolis; Iowa Service Unit, headquartered at Proviso in Chicago; and Proviso Service Unit, headquartered at Proviso. C&NW facilities at Cudahy, Wisconsin, and at Marshalltown, Clinton, and Council Bluffs, Iowa, were closed at the same time. (UPRR Info magazine, July-August 1995, page 6)

August 1, 1995
UP merged with Western Railroad Properties (WRPI), a C&NW subsidiary organized to build its line into the Wyoming Powder River Basin. (Union Pacific, Law Department records)

October 1, 1995
C&NW was formally merged into UP. (Railroad Retirement Employer Status Determination) (another, unrecorded source showed June 23, 1995 as the formal merger date; more research is needed)

Referring to effective dates for the UP-C&NW merger, Matt Holman wrote on June 19, 2006:

In the memos my father received at UP (as a National Equipment Manager) in 1995 was an itemized letter detailing the UP's planned and subsequent CNW purchase (since he would be "inheriting" all of CNW's plain boxcar fleet in the deal to his management responsibilities).

The first memo showed up in March after the federal government approved UP's takeover proposal (March 7, 1995) after much deliberation since mid-1994. As I recall it was about a 4-page document on UP stationary.

March 16, 1995 was the date UP announced via merger agreement the CNW stock purchase, to be culminated by April 25, 1995. The buyout would take place incrementally over that period (March 23, 1995 remaining shares being bought out via cash tender at $35 a share), and the official merger/buyout date was noted as April 25, 1995 effective end of the business day.

By UP's consideration, CNW's last day was April 25. Full corporate immersion by UP of CNW took place on May 1, 1995- although the UP then made the corporate merger retroactive to January 1, 1995 to reflect CNW's earnings for the partial year on UP's 8-K filings for 1996 because the merger was filed as a "purchase". This was when CNW folks started answering the phone as UP, and CNW lading and billing info cut-over to UP's TCS was started -that first night required my father to be downtown to help initiate the transfer starting at 1201 AM, later that year they finally fully cut over CNW's system to TCS - even though in court, federal arguments were being heard challenging the merger. (I have a slide of the CNW Division offices at South Pekin, IL flying the UP flag on May 15, 1995.)

Corporate lawsuits were finalized and settled June 26, 1995 in Delaware courts, fully clearing UP/MP corporations control of the CNW corporation.

The whole mess of the problem is the distinction between the rail entity and corporate side of things, since my father did work with both UP Corporation as an auditor and UP railroad as a management type I did get to see both sides of the business. It is important at this CNW/UP juncture because while the UP rail assets were acquiring CNW, UP Corporate was divesting itself of it's natural resources assets and courting SP.

Missouri Kansas Texas was merged with MP on December 1, 1989.

Missouri Pacific was merged into UP on January 1, 1997.


January 8, 1980
UP announced its intended merger with Missouri Pacific Railroad and Western Pacific Railway. (INFO, April 1980, page 4; Extra 2200 South, Issue 70, October-November-December 1979, page 20; Extra 2200 South, Issue 71, January-February-March 1980, page 18)

February 25, 1980
The boards of directors of Union Pacific Corporation and Missouri Pacific Corporation (the parent companies of their repsective railroads) sgned an agreement to merge. (INFO, April 1980, page 4)

September 12, 1980
The formal application for UP to control MP and WP was filed with the ICC.

October 20, 1982
The ICC approved UP's control and merger of Missouri Pacific and Western Pacific. (INFO, November 1982, page 7)

December 7, 1982
U. S. Court of Appeals rejected pleas from three competing railroads to stop the proposed UP-MP-WP merger. The decision allowed ten days for protestants to seek a stay from the U. S. Supreme Court to consider the appeals. (Pacific News, January 1983, page 3)

December 22, 1982
UP control and merger of WP was cleared by the U. S. Supreme Court, "At 2:25 p. m., December 22, 1982, the consolidation of the Union Pacific, Missouri Pacific and Western Pacific railroads became a fact." (INFO, January 1983, page 3) (Notice of the approved control of MP and WP was issued over the Union Pacific teletype system just after 10:00 p. m. on the evening of December 22, 1982.)

SP was given trackage rights between Kansas City and St. Louis over Missouri Pacific. D&RGW was given trackage rights between Pueblo, Colorado and Kansas City over Missouri Pacific.

January 1, 1983
UP control of Missouri Pacific Railroad took effect. (Union Pacific law department records)

January 1, 1986
The operating departments of Missouri Pacific and Union Pacific were conslidated into a single organization, with headquarters at Omaha. (Pacific RailNews, February 1986, page 5)

January 1, 1997
Missouri Pacific Railroad was formally merged into Union Pacific Railroad. (SEC, Union Pacific Form 10-K, dated March 18, 1998; Railroad Retirement Employer Status Determination)

January 1, 1997
"Railroad historians should take note of the following fact, as of January 1, 1997, the Missouri Pacific Railroad Company, offspring of the Missouri Pacific Railway Company of 1909 and the St. Louis, Iron Mountain and Southern Railway Company, ceased to exist when it was officially merged into Union Pacific. Union Pacific acquired Missouri Pacific in December of 1982." (Update Line, Union Pacific Communications Department, January 3, 1997; according to information on file in the Law Department, the last day for any Missouri Pacific business was January 7, 1997.)

February 1, 1997
"The Missouri Pacific Railroad became fully consolidated into Union Pacific Railroad Saturday, February 1, 1997. All MP stations became UP stations, all MP contracts were adapted as UP contracts and all MP interchanges became UP interchanges. All customers and the rail industry were officially notified about this consolidation and its effective date." (Update Line, Union Pacific Communications Department, February 4, 1997)

Missouri Kansas Texas Railroad

May 22, 1985
Union Pacific Corporation, through its Missouri Pacific subsidiary, announced that they had offered $108 million in cash and securities to purchase control of the Missouri Kansas Texas Railroad, known as the Katy. (Pacific News, August 1985, page 4; CTC Board, December 1985, page 18; CTC Board, June 1986, page 3; CTC Board, August 1986, page 8)

Before UP could either control, or merge with MKT, MKT's parent company Katy Industries was to purchase and retire 60 percent of 667,005 $110 income certificates, issued in 1958. These certificates had a total face value of over $73.3 million and had to be retired before MKT, or any successor, could pay dividends on its stock. Upon announcement of the proposed merger, a group of investors purchased, through brokerage houses, nearly half of the long forgotten certificates for $24, hoping to sell them back to Katy at their face value of $110. Katy Industries' first offer for $25 was unsuccessful and UP called off the merger talks in October 1985. Katy raised their bid to $33.50, with a deadline of November 20, 1985, which was extended to January 10, 1986.

Katy was unable to buy back its certificates and UP again withdrew their offer, after the final deadline of January 10, 1986. During summer 1986, UP made another offer, and Katy again made an offer to the certificate holders, raising the price from $33.50 to $39.50. They raised the offer to $39.75 for each $110 certificate on 9 July 1986, and apparently the offer was accepted.

November 14, 1986
UP and MKT applied for merger to the Interstate commerce Commission. Katy Industries owned and controlled both the MKT and the Oklahoma Kansas Texas (which Katy Industries had organized to purchase former CRI&P lines in Oklahoma and Texas). Both roads would be merged with Katy Industries as part of the UP-MKT merger. Final filing for the UP-MKT merger was on July 13, 1987, with hearings to begin on August 3, 1987. (Pacific RailNews, February 1987, page 5; CTC Board, August 1987, page 32)

The Katy Railroad Employees Association began making plans in January 1986 to purchase the MKT Railroad from Katy Industries if the UP-MKT merger failed. The Employees Association was opposed to the proposed UP-MKT merger but was unable to obtain financing. The Association was dissolved on 30 July 1987, because of both financing problems, and problems with the actual employee ownership plan.

May 16, 1988
UP's control of MKT was approved by the ICC. Other railroads were given 60 days to file any appeals to the merger. Missouri Kansas Texas Railroad would be leased to the Missouri Pacific Railroad until all operations were combined, then MKT would be sold to MP. (The Mixed Train, April 1988, page 10; CTC Board, June 1988, page 12; The Mixed Train, June 1988, page 16; Pacific Rail News, August 1988, page 5; The Mixed Train, August 1988, page 4)

August 12, 1988
Union Pacific was granted control of Missouri Kansas Texas. The final announced price was $110 million, to bring the 3,100-mile MKT system into UP's 21,500-mile system. (The Mixed Train, December 1988, page 9)

MKT was leased to UP-controlled Missouri Pacific until all of MKT's legal matters could be settled.

The following comes from the August 1988 issue of Pacific RailNews, page 4:

UP Purchase of Katy Approved by ICC -- One more independent Western railroad exits the scene as a result of the ICC's blessing of the acquisition of the Missouri-Kansas-Texas (Katy) Railroad by Union Pacific and Missouri Pacific railroads.

The decision, announced on May 16, indicates few conditions (mainly trackage rights to maintain competition) were attached to the sale.

UP announced plans to acquire the M-K-T Railroad from owner Katy Industries back in May 1985. An August deadline passed with Katy unable to gather at least 60 percent of 667,000 registered shares, a necessity to complete the UP deal. After a Jan. 10, 1986, deadline passed, by which time Katy was only able to acquire $12.5 million worth of shares (60 percent would have been worth $30.1 million) the UP-Katy merger was called off.

In summer 1986, the proposed M-K-T purchase by UP was on again. UP would pay $110 million for controlling interest. Katy was to purchase 60 percent of the shares, as before, but this time the offering per-share price was raised from $33.50 to $39.50; by July 18 more than 40 percent of the shares had been purchased. It looked hopeful for a petition to the ICC before year's end.

On Nov. 14, 1986, UP applied to the ICC to purchase the Missouri-KansasTexas Railroad. Katy subsidiary Oklahoma, Kansas & Texas would be merged into the Katy just before the sale to UP took place and many line duplications would be eliminated (a later filing before the ICC would abandon 213 miles of Katy and Missouri Pacific lines when the UP-Katy combination took place). Other casualties of folding the Katy into the UP system would by Katy's Parsons, Kansas, yard and its Denison, Texas, car shops.

In its decision, the ICC required UP to negotiate a trackage rights agreement between Kansas City and Omaha with either the Santa Fe, Southern Pacific or Kansas City Southern. An agreement with one of these railroads would have to be completed and submitted to the commission for approval within 90 days. The ICC will also monitor the effect of the merger on Rio Grande's interchange at Herington, Kansas, via trackage rights over the ex-MP Line gained in 1983 in the UP-MP merger. This would be reviewed one year after the UP acquisition of Katy is completed. The effect of this might also be a factor in D&RGW's application to buy SP.

UP agreed to give SP trackage rights at several Texas points, including the right to serve the Georgetown Railroad (near Austin) and the Great Southwest Industrial Park between Dallas and Fort Worth. SP also will gain trackage rights over the Galveston, Henderson & Houston Railroad (now jointly owned by UP and Katy), and in San Antonio and Houston.

The ICC also authorized AT&SF to purchase a one-sixth interest in the Texas City Terminal Railroad; this would allow SP to own the same portion of the railroad as UP and Katy.

Labor protection conditions were also attached. They mainly mandate negotiating agreements with UP and Katy before the purchase is completed, to protect workers whose jobs were abolished.

No announcement had been made at press time as to the proposed merger date.

January 1, 1989
All MKT and OKT employees were subject to UP rules. (Pacific Rail News, April 1989, page 10; The Mixed Train, July 1989, page 12)

November 30, 1989
MKT subsidiaries, San Antonio Belt & Terminal, and the Oklahoma, Kansas, & Texas were merged with MKT. (MKT had organized the OK&T to purchase former CRI&P lines in Oklahoma and Texas.)

December 1, 1989
MKT was merged into Missouri Pacific.

October 8, 2012
The original MKT lease of the former Chicago, Rock Island & Pacific Railroad mainline in Oklahoma was signed on November 1, 1982. To prevent the loss of this vital rail link within the state, Oklahoma had purchased the entire portion of Rock Island lines within the state's boundaries, which were then leased to Missouri-Kansas-Texas Railroad (known as MKT, or Katy) under the name of a new subsidiary called Oklahoma-Kansas-Texas Railroad, or OKT. As noted above, the OKT subsidiary was merged into MKT in November 1989, and the MKT was merged into MP the next day. MP was in turn merged into UP on January 1, 1997. But the lease of the Oklahoma lines remained in place for the entire 30-year period of the original lease dating from 1982. Just three weeks before the lease was set to end, allowing for the State of Oklahoma to offer a new competitive lease for the state-owned 312 miles of former Rock Island trackage, the Oklahoma and Union Pacific completed a purchase agreement for Union Pacific ownership of the trackage on October 8, 2012. (Union Pacific press release dated October 8, 2012)

Nevada Pacific Railway

Nevada Pacific Railway was incorporated on May 13, 1889, and was projected in competition with Central Pacific, to connect California with UP-controlled companies in Utah. Included as part of OSL&UN consolidation in July 1889.

OSL&UN completed grading and tunneling work in 1890-1891 along the line projected by Nevada Pacific, south of Milford and into Nevada to Caliente (Culverwell) along the route that was later completed by LA&SL. The work by OSL&UN was stopped due to the financial difficulties of Union Pacific that ended with UP's bankruptcy in October 1893.

Controlled by UP from March 18, 1890 to October 13, 1893

Consolidation in March 1890 of 11 Colorado and Wyoming railroads:

From Wikipedia, citing "Transcontinental railway strategy, 1869-1893: a study of businessmen" by Julius Grodinsky (Beard Books, 1962; ISBN 1-58798-003-7) pages 385-386:

Creation of the company resulted from Charles Francis Adams, Jr.'s desire to operate in the Texas Panhandle area, which would give Union Pacific control over the shipping of cargoes from the Gulf of Mexico seaports to the North. In May 1889 Union Pacific and Denver, Texas and Fort Worth Railroad signed an "offensive and defensive union". Union Pacific received access to the panhandle routes in exchange for letting DTFWR to operate on Union Pacific lines as far as New York. However, in November 1889 Union Pacific changed their tactics and instead directly purchased controlling stock of the smaller railways in Panhandle area. These assets were pooled together into a new entity named Union Pacific, Denver and Gulf Railway. It lasted until 1898 when it was merged with other companies to become the Colorado and Southern Railway.
