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.
The GP38 was introduced in 1966 and was built through 1971. The GP38-2 was built between 1972 and 1984. GP38-2 era is from 1972 until now. GP38 and GP38-2 were EMD’s most successful second-generation Geeps and many are still in use today.
