An EMD SD38 is a 6-axle diesel locomotive built by General Motors Electro-Motive Division between May 1967 and October 1971. Power was provided by an EMD 645 16-cylinder engine which generated 2000 horsepower (1.5 MW). As compared to the EMD 645E3 engine that was turbo-charged and produced 3000HP from the V16 configuration. This locomotive shared the same common frame with the SD39, SD40 and SD45. 52 examples of this locomotive model were built for American railroads and one was built for Canadian railroads. The SD38 was succeeded by an upgraded Dash 2 version called the EMD SD38-2.
