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]

The GP9's extreme versatility is, of course, what made them so successful, and many continue to be found today in freight service on both short lines and regionals (as well as museums and tourist lines).
