The EMD GP38 is a 4-axle road switcher diesel-electric locomotive built by General Motors Electro-Motive Division between January 1966 and December 1971. The locomotive's prime mover was an EMD 645 16-cylinder engine that generated 2,000 horsepower (1.49 MW).

The company built 706 GP38s for North American railroads.

In 1972, EMD began making an updated model, the GP38-2.

Rebuilds[edit]

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.

In 2007, Norfolk Southern rebuilt a 1969 GP38 into an experimental electric locomotive dubbed the Altoona Works BP4.
