The EMD SDP35 is a model of 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between July 1964 and September 1965. Power was provided by an EMD 567D3A 16-cylinder engine which generated 2,500 horsepower (1.9 MW). Essentially this locomotive was an EMD SD35 equipped with a steam generator, located in the extended long hood end, for passenger use. 35 examples of this locomotive model were built for American railroads.
