UP 99 UP 423 UP 3100 UP 3200 UP 3399 UP 3999 Aug 1968 18 Mar 1985 UP 99 was sold for scrap to St. Louis Auto Shredding, East St. Louis, Illinois, 12 November 1985.

General Notes:

  1. UP 3100 was rebuilt from UP SD24 423 (EMD 25381, Sep 1959) in August 1968 as a prototype for a possible rebuild program for the SD24s, making them similar to the SD40s. The rebuild effort included a constant speed EMD 16-645 3000 horsepower engine (with speed control taking place by changing the level of excitation of the main generator) and traction motors permanently connected in parallel. UP tried many other features, including a variable dynamic braking feature, first used on the small 51-75 single unit turbines. UP 3100 was also the first unit on UP to have the capability of a self-load test, rather than being connected to an external load box. This self load feature was first delivered on UP's DDA40Xs, and on almost all production units from EMD after 1971. The more troublesome test features were soon removed; the constant speed engine only lasted about two years, the traction motors were also connected in a normal fashion at that time. When built, the unit was equipped with fiberglass hood doors, with magnetic latches. The latches were changed to the EMD standard "knuckle buster" design in March 1974 when the unit (as UP 3399) received a new generator in Salt Lake City.
  2. UP 3100 (SD24M) rebuilt from UP 423 (SD24) in August 1968; renumbered to UP 3200 in December 1970; renumbered to UP 3399 in March 1972; renumbered to UP 3999 in November 1976; renumbered to UP 99 in October 1978; retired and scrapped in November 1985.

General Notes:

  1. All units are at least the second (2nd) instance of UP using each number on an EMD SD40-2.
  2. Most units were renumbered from units in UP's 3700, 3800, and 3900 series in 2002-2004 to clear those number series for use by new SD70M units.
  3. Other units renumbered from UP's 7800 and 7900 series numbers to clear those number series for use on new GE C45C-CTE units to be delivered in 2007 and 2008.

Notes:

  1. UP 3105 was donated (along with caboose UP 24567) to Railway & Locomotive Historical Society, Southern California Chapter, and moved to Los Angeles County Fairplex in Pomona, California, to replace UP steam 4-8-8-4 4014 as part of the railroad display; the actual move to exchange UP 4014 for UP 3105 and caboose 24567, took place in January 2014.
  2. UP 3118 (2nd) was wrecked (sideswipe) during May 2008 in switch service at West Colton, California; scrapped by UP at West Colton, California during mid January 2009.
  3. UP 3503 was sold to CIT Equipment Finance Group (CITX) on 27 May 2005 to replace CITX SD40-2 2807, destroyed while in lease service on UP on 3 May 2004 at San Antonio, Texas.
