After UP took over the SP in 1996, several older SP units were repainted into UP colors. While UP had many roster changes, it was common during this period for batches of locomotives to get renumbered. Our models depict the renumbered versions before they were retired.

PROTOTYPE SPECIFIC INFORMATION
The SD40T-2 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division having a 16-cylinder EMD 645E3 diesel engine producing 3,000 horsepower (2,240 kW). 312 SD40T-2s were built for North American railroads between April 1974 and July 1980. This locomotive and the SD45T-2 are popularly called tunnel motors, but EMD’s term is SD40-2s with “cooling system modifications” because they were designed for better engine cooling in tunnels. The difference between this locomotive and its non-tunnel motor cousin, the SD40-2, are the radiator intakes and radiator fan grills located at the rear of the locomotive. The radiator air intakes in this model were along the deck to allow more fresh, cooler air to enter and less hot exhaust fumes lingering around the tunnel’s ceiling.
