An EMD GP38-2 is a four-axle diesel-electric locomotive of the road switcher type built by General Motors Electro-Motive Division. Part of the EMD Dash 2 line, the GP38-2 was an upgraded version of the earlier GP38. Power was provided by an EMD 645E 16-cylinder engine, which generated 2000 horsepower (1.5 MW).
1,801 examples of this locomotive model were built for American railroads, 254 for Canadian railroads and 133 for Mexican railroads. In addition to these, 20 more examples were built with high short hoods containing steam generators for use on Mexican railroads.
