EMD GP39

The EMD GP39 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between June 1969 and July 1970. The GP39 was a derivative of the GP38 equipped with a turbocharged EMD 645E3 12-cylinder engine which generated 2,300 hp (1.72 MW).[1][2]

23 examples of this locomotive model were built for American railroads.[3]

Burlington Northern Railway later rebuilt GP30 and GP35 locomotives that it classified as GP39s, but they were not built as such by GM/EMD.

Production history

Twenty of the original 23 were built for the Chesapeake and Ohio Railway, while the other buyers were Kennecott Copper (2) and Atlanta & St. Andrews Bay (1).[3]

GP39DC

Two examples of the GP39 were built as GP39DC locomotives in June 1970. These used a DC main generator instead of the alternator used on the standard GP39 units, but were otherwise identical. 2 examples of this locomotive model were built for Kennecott Copper Company as 1 and 2, later sold to Copper Basin Railway as 401 and 402.

Successor

Though the GP39 was not a popular locomotive, EMD later revisited the idea of a turbocharged GP38 with its GP39-2 in 1974.[4]
