Rio Grande #5371

Rio Grande #5371. . , "Tunnel Motor" diesel , The Denver and Rio Grande Western Railroad #5371 was built in 1975. It is a 3000 HP General Motors model SD40T-2 diesel-electric freight locomotive. The 5371 was one of 73 engines of this type delivered to the D&RGW by the Electro-Motive Division (EMD) of GM. This locomotive used a Southern Pacific Railroad-inspired cooling radiator designed to prevent overheating in long tunnels and snowsheds. The large grilled air intake is located at the rear of the locomotive at catwalk level, rather than near the top of the long hood as on conventional units of this era. This design prevents ingesting hot gases into the cooling radiators while operating at low speeds. The 5371 was used for years on heavy unit trains of coal, as well as priority fast freight trains across the Rio Grande system between Ogden and Denver. In later years it was assigned to local and helper duty at appropriately-named Helper, Utah, prior to being retired in 2008. , -Daniel B.
