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. 1251 examples were built for American railroads, 26 were built for Canadian railroads and 57 were built for Mexican railroads. Power was provided by a turbocharged EMD 567D3A 16-cylinder engine which generated 2,500 horsepower (1,860 kW).[1]

Many railroads traded in Alco FA units and EMD F-units for GP35s, reusing the trucks and traction motors. Examples with Alco trucks include those owned by Gulf, Mobile and Ohio, Southern Railway, and Ann Arbor Railroad.
