The SD40T-2 was built between April 1974 and July 1980 by EMD.

The locomotives were equipped with a 16cyl 645E3 prime mover capable of 3000 horsepower.

Called "Tunnel Motor" because of a cooling system modification over the SD40-2 to move the radiator intakes along the deck.

This allowed for better engine cooling in tunnels.

Rio Grande, Southern Pacific, and subsidiary Cotton Belt, were the original purchasers.

The SP version has a 4,400 gallon fuel tank, while the Rio Grande version has a 4,000 gallon fuel tank.

When the Rio Grande and Southern Pacific were absorbed into the Union Pacific, all SD40T-2's were owned by Union Pacific.

In the early 2000's, some were retired, while others were sold off to various short line railroads (or other countries) and are still in service today.

By 2008, none were left on the Union Pacific in DRGW or SP reporting marks.

The last Rio Grande unit, DRGW 5371, still in Rio Grande paint, was retired in March 2008 and placed on display at the Utah State Railroad Museum in Ogden, UT.
