SD40T-2 Diesel Locomotive
Prototype Information
The EMD SD40T-2 is a six-axle diesel-electric locomotive that EMD built from 1974 to 1980. It belongs to the Dash 2 series and serves as a modified version of the SD40-2. Engineers designed it specifically for mountainous terrain and long tunnels, which earned it the nickname “tunnel motor.”
Instead of placing the radiator air intakes high on the body, EMD moved them low, near the walkway. This design let the locomotive pull in cooler air from near the tracks. As a result, it performed better in tunnels, where heat builds up quickly.
Southern Pacific and Denver & Rio Grande Western ordered most of the units. Both railroads needed power that could handle steep grades and tight spaces in the mountains. The SD40T-2 delivered 3,000 horsepower using a 16-cylinder 645E3 engine. It shared most of its components with the standard SD40-2, which made maintenance easier.
Even after production stopped in 1980, many SD40T-2s stayed active. Some railroads rebuilt them, and others passed them on to shortlines and regional carriers. Thanks to its durability and smart design, the SD40T-2 built a strong reputation as a reliable mountain workhorse.
