Description
The GP40 is a 4-axle diesel-electric road-switcher
locomotive built by General Motors, Electro-Motive Division between November
1965 and December 1971. It has an EMD 645E3 16-cylinder engine generating 3,000
hp (2,240 kW).
The GP40 is 3 feet longer than its EMD 567D3A-engined
predecessor, the GP35, and distinguished visually by its three 48-inch radiator
fans at the rear of the long hood, while the GP35 has two large fans and a
smaller one in between. It was built on a 55 ft (16.76 m) frame; the GP35 was
built on a 52 ft (15.85 m) frame - as was the GP7, 9, 18, and 30. The difference
in length can be seen in the GP40's ten handrail stanchions compared to the
GP35's nine.[1]
1,187 GP40's were built for 28 U.S. railroads; 16 were
built for one Canadian carrier, Canadian National; and 18 were built for two
Mexican carriers, Ferrocarril Chihuahua al Pacifico and Ferrocarriles Nacional
de Mexico. 60 units were built with high-short-hoods and dual control stands for
Norfolk & Western Railway. Two passenger versions, the GP40P and GP40TC, were
also built, but on longer frames to accommodate steam generators and HEP
equipment.
On Jan. 1, 1972 the GP40 was discontinued and replaced by
the GP40-2, which has a modular electrical system and a few minor exterior
changes.
