The company built 706 GP38s for North American railroads.

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

Rebuilds

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.
