General Notes:

a. UP 31-53 were built using reconditioned truck and bolster assemblies from UP's retired 4500 GTEL gas turbine locomotives.
b. UP 52 was delivered rated at 5,600 horsepower as a field test of a Cummins PT improved fuel system. The modification was removed and the unit de-rated to 5000 horsepower in October 1966.
c. During 1969 a plan was devised to equip UP's U50 units with two GE 2800 horsepower engines (total rating of 5,600 horsepower) and renumber them to the 5600 class. Another proposal, also in 1969, was to strip all mechanical components from the locomotives, except the traction motors, equip them with large fuel tanks above the walkways, and use them as powered fuel tenders. Neither of these proposals went beyond the drawing board stage.

General Notes:

a. Built as UP 3601-3649, 3600; renumbered to UP 1-50 between September 1978 and March 1979 to avoid conflict with new SD40-2s.
b. By July 1981, 30 of the 48 remaining SD45s were in long term storage. Between August 1981 and June 1982, five more were retired and rebuilt to Sulzer-powered SD45Ms, joining UP 34 rebuilt to UP 60 in August 1980, leaving an SD45 fleet of 43 units. By May 1982, 35 of those 43 units were in storage, with the remaining eight units being placed in storage within six months.
c. Of the 50 units, one (UP 43) was wrecked in 1981, and six were rebuilt as Sulzer units in 1980-1982; the remaining 43 units were stored after 1982, and retired and sold for scrap in 1985-1988.
d. Six units were rebuilt to Sulzer-powered SD45M in 1981, retired in 1983, and sold to Precision National in late 1987; these six units remained in storage at Presion's Mount Vernon, Illinois, shop when NRE bought all of Precision's assets in late 1997; rebuilt to SD40-2 specifications and leased to UP as 4700-class units.
e. In January 1988, the last two SD45s, UP 4 and UP 41, were sold to Precision; these two units remained in storage at Presion's Mount Vernon, Illinois, shop when NRE bought all of Precision's assets in late 1997; UP 41 was rebuilt to SD40-2 specifications and leased to UP as 4700-class units. The last unit, UP 4, is unaccounted for after being seen at NRE in 2000.
f. The noses from scrapped UP 21, 27, and 31 were sold in August 1994 by VMV Enterprises, Paducah, Kentucky; shipped loaded on a flat car.
g. UP 1-21, 50 were built on EMD order number 7975, UP 22 was built on EMD order number 7107; UP 23 was built on EMD order number 7108; UP 24-49 were built on EMD order number 7077.

UP 20 Aug 1992 492 J300 12 Apr 1993 Lease ended on November 17, 1993; returned to Republic Locomotive Works.

General Notes:

a. Built by Republic Locomotive Works as the prototype for a new switcher design; construction begun in July 1992; the RD20 was displayed (not yet fully operational) at the Railway Supply Association show in October 1992.
b. Equipped with EMD Blomberg trucks, Detroit 16-149TI diesel engine, and 62:15 gear ratio
c.

The Republic RD20 locomotive was built by Republic Locomotive Works in August 1992, on the frame of an EMD GP35. Leased to Union Pacific from April to November 1993. Sold to Georgetown Railroad; sold to LeTourneau Drive Systems (LETX) as their number 20 as early as June 2003. Sold in mid 2007 by David Kramer/Diesel Locomotive Co. (DLCX); moved in 2009 for storage to Burlington, Iowa, on Burlington Junction Railway; moved in 2011 to Independent Locomotive Services at Bethel, Minnesota; still there as of July 2014. (Photos at RailroadPicturesArchive)

The following comes from Railfan & Railroad magazine, June 1993:

The RD20 -- In mid-March 1993, Republic Locomotive announced it had successfully field tested its new RD20 model locomotive. Developed in conjuction with Detroit Diesel Corporation, the four-axle RD20 prototype features a 2000-hp Detroit Diesel 16V-149TI DDEC engine, an 8000 amp a.c. alternator and d.c. traction motors. Republic says "the RD20 is the first diesel locomotive produced in North America to utilize a totally solid state Silicon Controlled Rectifier control system" which "eliminates all electromechanical switchgear, contactors and relays while permitting individual axel control for improved wheel slip control." The RD20 can be operated with a cruise control-style feature which automatically maintains a set speed regardless of changes in track curvature and gradient. A cellular communications package transmits locomotive diagnostic information which can be monitored remotely by maintenance personnel at any location with access to a computer, modem and phone line. Republic's RD20 design can be modified for any horsepower rating up to 2500 h.p. and is available in four- and six-axle configurations in most track gauges. An optional Head End Power generator is also available.

d. Built on the frame of an GP35, possibly from Louisville & Nashville 1111 (EMD number 29476; May 1964; frame number 7743-1), which was renumbered to Seaboard System 1111; to SBD 4308; to CSX 4308.
e. Leased to UP for six-month evaluation period, from April 12, 1993 to November 17, 1993; used by UP at Kansas City; delivered to SP (SSW) on 11 December 1993.

UP 50 GE 101 Nov 1948 30159 Jul 1949 Apr 1951 Returned to GE in April 1951.

General Notes:

a. Built as GE 101, a double-cab 4500 horsepower gas turbine locomotive, painted dark green with yellow stripes; tested on Nickel Plate and Pennsylvania railroads from November 1948 until June 1949.
b. GE 101 was repainted and renumbered to UP 50 in late July 1949 (never actually owned or leased by UP); the locomotive tested on UP from late July 1949 to late April 1951.
c. Tested on the SP during May and June 1951, then returned to GE; scrapped by GE in 1953.
d. "This unit was strictly a GE demonstrator. It never left GE ownership, but was painted in UP colors from 6/49 to 3/51 when it was returned to GE for retirement. Steinbrenner notes that the ALCO-GE lettering on the nose of #101 was there because of the joint agreement between ALCO and GE, and that ALCO did not participate in the design and building of this unit. See The American Locomotive Company A Centennial Remembrance p. 341. (Ed Cooper, email to LocoNotes discussion group, dated November 22, 2006)

General Notes:

a. UP 51-60 single-cab 4500 horsepower gas turbine locomotives were delivered without tenders; the tenders were added later by UP, after being rebuilt from FEF-1 class 4-8-4 (800-819) steam locomotive tenders.
b. UP 51-60 were nicknamed "Standard Turbines", and were equipped with fully enclosed car bodies.
c. In May 1953, UP 57 was equipped to burn propane, which required the addition of a pressurized tender; road tests were run between Los Angeles and Las Vegas; the test was considered a success, although it was decided not to convert the rest of the fleet; the locomotive was converted back to burn residual fuel in January 1954. This was the first use of aluminum-colored trucks on UP locomotives.
c. UP 58-60 were equipped for multiple-unit operation with diesels.
d. The truck assemblies from UP 51-56 were reconditioned by UP at Omaha in 1962 and shipped to GE-Erie for use on U25Bs; the car bodies were scrapped by UP at Omaha and Cheyenne.
e. The truck and bolster assemblies from UP 57-60 were reconditioned by UP at Omaha in 1963 and 1964 and shipped to GE-Erie for use on the U50s; the car bodies were scrapped by UP at Omaha and Cheyenne.

General Notes:

a. UP 60-65 were rebuilt from standard EMD SD45s by Morrison Knudsen at Boise, Idaho, during 1980 to 1982 as a test program using Sulzer diesel engines from Switzerland. Included in the program along with these six UP units were four ATSF SD45s, road numbers 5405-5408. The ATSF units were completed by Morrison Knudsen during mid 1981 and rebuilt back to standard SD45s, road numbers 5496-5499, by ATSF during 1984 and 1985.
b. The rebuild effort required extensive modification of the car body to accommodate the new engine. The most visible changes were an additional two inches of car body width along the hood sides, and a screen intake at the rear of the car body on the left (fireman's) side. Morrison Knudsen did the car body modifications on the first UP unit (UP 60/34). UP did the carbody modifications on the other five units in its own Omaha, Nebraska, shops prior to the units' moving to Morrison Knudsen at Boise.
c. All six units were worked east to North Platte with their original SD45-series numbers. Upon painting at North Platte, each unit was renumbered to its 60-series number.
d. Equipped with Sulzer 16ASV25R-30 engine and 62:15 gear ratio.
e. Union Pacific called these units SD45Ms; Morrison Knudsen used TE83-6S (Tractive Effort, 83,000 pounds, 6 axle, Sulzer).

Note:

1. All six units were retired on 21 December 1983, while stored at Council Bluffs, Iowa; sold to Precision National Corp., Mount Vernon, Illinois, 29 October 1987; all six units were still at the Precision facility 10 years later when National Railway Equipment in November 1997 bought the assets of the bankrupt Precision National Corp; all six units were sold by NRE to CIT Group, Inc., rebuilt by NRE to SD40-2s (still in their modified SD45 carbodies) and leased to UP with the following new UP numbers:

General Notes:

a. UP 70-83 were built using reconditioned GE 752 traction motors (with 74:18 gear ratio) from trade-in Alco FA and FB cab units. EMD used the designation 752E20A for these reconditioned traction motors. UP 84 was built using the reconditioned EMD D67B1 traction motors from wrecked trade-in UP GP9 159 and was equipped with 62:15 gearing.
b. UP 71, 73, 74, 80, and 81 were originally equipped with 79:24 high speed gear ratio; later changed to 74:18 gear ratio.
c. UP 82 was equipped for Radio Control (RC) operation in May 1968, serving as the control unit, matching UP 82B which served as the remote. All radio control equipment was removed from both units during July 1973 at Salt Lake City, Utah.
d. Five additional DDA35 units were ordered by UP for delivery during 1966. The units were to be numbered UP 85-89. EMD assigned builder's numbers 29999-30003 to these five units. The order was canceled in lieu of SD40s. EMD did not use the builder's numbers for other locomotives.
e. UP 70 was the first DDA35 to receive UP's "We Can Handle It" slogan, in late April 1972.
f. During 1977 and 1978, UP began removing the sand boxes from the ends of both the DDA35s and the DD35s, replacing them with side sand boxes that were fabricated by UP's Omaha Shops, similar to factory-built sand boxes applied to the 6900 class DDA40Xs. The end sand boxes were removed to get dust and grit associated with the sand boxes out of the end control cabinets.
g. UP 70-83 were built on EMD order number 7797.
h. UP 84 was built on EMD order number 7798.
e.

Terry Kolenc reviewed his slides, and found that the following 9 units were in service during August and September of 1979: UP 71, 72, 75, 77, 78, 79, 80, 82, 83

General Notes:

a. During 1977, UP began removing the sand boxes from the ends of the DDA35s and the DD35s, replacing them with side sand boxes that were fabricated by UP's Omaha Shops, similar to the factory-built sand boxes applied to the 6900 class DDA40Xs. The end sand boxes were removed to get dust and grit associated with the sand boxes out of the end control cabinets.
b. As part of a reliability test program for the DD35 locomotives, three DD35s received modified electrical cabinets on the following dates. The modification forced the sand boxes from the ends, to the sides, similar to the sand box configuration used for the DDA40X Centennial units.
  • April 1975 - UP 91B received GE electrical gear, inside sealed electrical cabinets, completed at UP's Omaha shops.
  • February 1973 - UP 93B received a solid state control electrical cabinet on just its No. 2 end. At the same time, UP 93B was equipped with a Genisco transition programmer.
  • February 1973 - UP 98B received solid state control electrical cabinets on both ends.
c. UP 82B was equipped for Radio Control (RC) operation in May 1968, serving as the remote unit, matching UP 82 which served as the control unit. All radio control equipment was removed from both units during July 1973 at Salt Lake City, Utah.
d. UP 97B was set-up at by UP at Omaha, Nebraska, on 22 September 1964.
e.
