Description
Railroad Short Name: UP
The SD40-2 was introduced in January 1972 as part of EMD’s Dash 2 series, responding to competing products from GE and ALCO. Reliability and versatility of the 3,000-horsepower SD40-2 made it the best-selling model in EMD’s history and the standard of the industry for several decades after its introduction. The SD40-2 was an improvement over the SD40, with modular electronic control systems like those of the experimental SD45X and DDA40X. The last SD40-2 delivered to a United States railroad was built in July 1984, with production continuing for railroads in Canada until 1988.

This release represents “standard” Union Pacific SD40-2s as they appeared in the mid-1980s, with two major spotting features:
20-inch high cab side numbers (the numbers having been moved there from their location on the long hood, starting in November 1980). This was done to improve the visibility of the numbers when being viewed by the low-resolution video cameras then in use by UP at major yards and terminals.
Grey-colored trucks. These replaced aluminum paint which had been in use since 1953. This change was implemented in February 1984, to avoid the high cost of repainting the entire Missouri Pacific fleet.
