The EMD SD38-2 is a six-axle diesel locomotive built by General Motors Electro-Motive Division (EMD) from 1972 to 1979. EMD built 83 of these medium road-switchers, which were used in both yard and mainline roles. Part of the EMD Dash 2 line, the SD38-2 was an upgraded SD38 with modular electronic control systems, HT-C trucks, and many other detail improvements. The locomotive's power was provided by an EMD 16-645E 16-cylinder engine, which could generate 2,000 horsepower (1,500 kilowatts).
