HO SD40T-2 Locomotive with DCC & Sound, D&RGW #5402

During the late 1960’s and early 1970’s the Southern Pacific was looking for ways to solve the problem of their diesels overheating in their many tunnels and snow sheds. They determined that problem was caused by the locomotive’s taking in their own hot exhaust gases while in the confines of the tunnels. The solution came from EMD’s development team which relocated the radiator cooling intakes to the lower portion of the rear of the car body, creating what railfans dubbed the “Tunnel Motor.” This modification allowed the locomotives to take in cooler air that was nearer to the tunnel floor and thus reducing overheating. The Rio Grande was experiencing the same issues and decided to get some Tunnel Motors of their own, ordering some 73 SD40T-2’s in total in 5 separate orders. The last order, #5398-5413 were built in 1980. Features included a 4000 gal fuel tank, nose gyralights, and extended range dynamic brakes with exhaust silencer. The company wanted to order more of them but EMD convinced them to get their new SD50’s instead.

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 pro- ducing 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.
