The EMD GP39-2 is a 4-axle diesel locomotive built by General Motors Electro-Motive Division between 1974 and 1984. 239 examples of this locomotive were built for American railroads. Part of the EMD Dash 2 line, the GP39-2 was an upgraded GP39. The power for this locomotive was provided by a turbocharged 12-cylinder 12-645E3 diesel engine, which could produce 2,300 horsepower (1,720 kW).

Unlike the original GP39, which sold only 23 examples as railroads preferred the reliable un-turbocharged GP38, the GP39-2 was reasonably successful, ascribed to its better fuel economy relative to the GP38-2 which became of more interest in the 1970s energy crisis, and to its better performance at altitude.^[1]
