This locomotive model was purchased by the [[Denver and Rio Grande Western Railroad]], the [[Southern Pacific Transportation Company|Southern Pacific Railroad]], and its subsidiary [[St. Louis Southwestern Railway|Cotton Belt]]. Southern Pacific's version has a {{Convert|4400|usgal|L impgal|adj=on|sigfig=3}} fuel tank and is {{Convert|70|ft|8|in}} long. Rio Grande's version has a smaller {{Convert|4000|usgal|adj=on|sigfig=3}} fuel tank.

In 2005, most of these units were owned by Union Pacific or leasing companies. By 2008, none were left in service on UP with SP or DRGW reporting marks.<ref>{{Cite web|url=https://www.american-rails.com/tunnel-motors.html|title=Tunnel Motors, SD45T-2/SD40T-2|website=American-Rails.com|access-date=2019-02-13}}</ref> DRGW 5371 was the last one, retired in March 2008, and now resides at the [[Utah State Railroad Museum]] in Ogden Utah. Another SD40T-2 is preserved at the Boone & Scenic Valley Railroad in Boone, Iowa, and in late 2017, it was announced that another Rio Grande SD40T-2 was going to be donated to the Colorado Railroad Museum in Golden, Colorado. On August 22, 2018, UP 9871 (formerly D&RGW 5401) was moved to the museum grounds, and was since “unpatched”, painted to resemble its original appearance from 1980, which included painting the number back to 5401. Three former Rio Grande units, 5391, 5413,and 8795, are still active on the Wheeling and Lake Erie Railroad out of Brewster, Ohio.

The SD40T-2 is a model of diesel-electric locomotive built by General Motors Electro-Motive Division in the United States. The SD40T-2 is equipped with a 16-cylinder EMD 645E3 diesel engine producing 3,000 horsepower (2,240 kW). 312 SD40T-2s were built for three railroads in the United States between April 1974 and July 1980. This locomotive and the SD45T-2 are popularly called tunnel motors, but EMD's term is SD40-2 with "cooling system modifications" because they were designed for better engine cooling in mountainous areas.[1] The difference between this locomotive and its non-tunnel motor cousin, the SD40-2, are the radiator air intakes are located lower down at the rear of the locomotive.
