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.

Burlington Northern

Without a doubt, BN was very happy with the EMD SD40-2. The reliability and ease of maintenance made these locomotives a company favorite. BN’s operating territory in the mountainous Pacific Northwest included routes with tunnels, including the 7.80-mile-long Cascade Tunnel. Consequently, it doesn’t seem too far-fetched for BN to have possibly ordered SD40T-2’s to work this territory. In an alternate timeline, BN tested SP’s SD45T-2’s and SD40T-2’s, liked the results and ordered 20-units for use on former Great Northern and Northern Pacific trackage. We think that these Tunnel Motors look great in Cascade Green and black and are a fine addition to our Legendary Liveries series!
