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 .
23 examples of this locomotive model were built for American railroads.
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 &amp; St. Andrews Bay (1). Though the GP39 was not a popular locomotive, EMD later revisited the idea of a turbocharged GP38 with its GP39-2 in 1974.
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.
GP39X.
The EMD GP39X is a diesel-electric locomotive built by the General Motors Electro-Motive Division. All six units built were constructed for the Southern Railway with Southern's characteristic high short hood. They were updated by EMD at Norfolk Southern's (Southern's successor) request to EMD GP49 standards in 1982. Norfolk Southern retired them in 2001, and they now are owned by Tri-Rail, after being upgraded with head end power and a lowered short hood.
