This locomotive model was purchased by the Denver and Rio Grande Western Railroad, the Southern Pacific Railroad, and its subsidiary Cotton Belt. Southern Pacific's version has a 4,400 gallon fuel tank and is 70' 8" long. Rio Grande's version has a smaller 4,000 gallon fuel tank. After merging with Rio Grande, the Southern Pacific and later Union Pacific owned every SD40T-2.
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. 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. UP still runs a few units repainted in its own livery.
