The EMD GP38 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between January 1966 and December 1971. The locomotive's power was provided by an EMD 645 16-cylinder engine which generated 2,000 horsepower (1.49 MW).
706 examples of this locomotive model were built for North American railroads.
In 1972, it was replaced by an updated model, the GP38-2.
A number of GP38s have been rebuilt into the equivalent of a GP38-2.
Conversely, a number of higher horsepower 40 Series locomotives have been rebuilt into the equivalent of a GP38-2 (GP38AC), by the removal of the turbocharger and the substitution of twin Roots blowers.
