An EMD GP39DC is a 4-axle diesel locomotive built by General Motors Electro-Motive Division in June 1970. Power was provided by a turbocharged 12-cylinder EMD engine that generated 2,300 hp. This locomotive model was basically a GP39 with DC main generator instead of an alternator.

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
