An EMD SD38AC is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between June and October 1971. This model is an SD38 with an AR10 alternating current alternator instead of the SD38's normal direct current generator. It produces 2,000 horsepower (1,500 kW) from a 16-cylinder EMD 645E roots blown prime mover. It came equipped with or without dynamic brakes. This locomotive shares a common frame with the SD39, SD38, SD40 and SD45. The SD38AC was a transition between the SD38 and it's successor, the SD38-2. 15 examples of this model were built; 6 for B&LE, 8 for DMIR and one for BC Hydro.
