SD40-2F Diesel Locomotive

Prototype Information

GMD produced the SD40-2F between 1988 and 1989 as a specialized variant of the SD40-2 for Canadian Pacific Railway. While it shared the same reliable 3,000-horsepower, 16-cylinder 645E3 engine as the standard model, it featured a distinctive full-width cowl body. This streamlined design protected the engine and walkways from heavy snow and ice during harsh Canadian winters. It also utilized the Canadian Safety Cab, providing crews with a more comfortable and spacious environment. Because of its unique silhouette, railfans often referred to the locomotive as a Red Barn.

Canadian Pacific was the only railroad to purchase the SD40-2F, ordering a total of 25 units. These locomotives represented the final evolution of the SD40-2 line and served as a mechanical bridge to the newer SD60 series. They spent most of their careers hauling heavy freight across the Canadian prairies and through the rugged Rocky Mountains. Despite their specialized body style, they remained mechanically compatible with the rest of CP’s vast SD40-2 fleet. Canadian Pacific eventually retired the fleet in the 2010s, but several units found new lives with Central Maine & Quebec Railway and later other regional operators.
