The EMD SD50 is a 3500-horsepower (2610 kW) diesel-electric locomotive built by General Motors Electro-Motive Division. It was introduced in May 1981 as part of EMD’s 50 Series but prototype SD50S locomotives were built from 1980; production ceased in January 1986. The SD50 was in many respects a transitional model between EMD’s Dash 2 series which was produced throughout the 1970s and the microprocessor-equipped SD60 and SD70 locomotives.
