The EMD GP9 is a four-axle diesel-electric locomotive built by General Motors' Electro-Motive Division between 1954 and 1959. The GP9 succeeded the GP7 as the second model of EMD's General Purpose (GP) line,[1] incorporating a new sixteen-cylinder engine which generated 1,750 horsepower (1.30 MW).[2] This locomotive type was offered both with and without control cabs; locomotives built without control cabs were called GP9B locomotives.
