The EMD GP35 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between July 1963 and December 1965 and by General Motors Diesel between May 1964 and January 1966. The locomotive's power was provided by an EMD 567D3A 16-cylinder engine which generated 2,500 horsepower (1,860 kW).Many railroads traded in Alco and EMD F units for GP35s, reusing the trucks and traction motors. Some railroads had EMD reuse the Alco trucks on the GP35s.
