An EMD GP9 is a 4-axle diesel locomotive built by General Motors Electro-Motive Division between January 1954 and August 1963. Power was provided by an EMD 567C 16-cylinder engine which generated 1,750 horsepower (1.3 MW)[1]. This locomotive type was offered both with and without control cabs; locomotives built without control cabs were called GP9B locomotives. The GP9B locomotives were built between February 1954 and December 1959.

3,436 examples of this locomotive model were built for American railroads, 646 were built for Canadian railroads and 10 were built for Mexican railroads. Of the GP9B, 165 examples were built for American railroads.

Many rebuilt GP9s remain in service today with shortline railroads and industrial operators. Some remain in rebuilt form on some major Class I railroads, or as switcher locomotives. Canadian Pacific Railway still has many in its fleet in 2007 as switcher locomotives.

[edit] Preservation

Several GP9 locomotives have been preserved at various railroad museums and as "park engines". The geep is very popular among shortline railroad and can still be seen on the smaller railroads around the U. S.

The Western Pacific Railroad Museum at Portola, California rosters 3 of these units: Western Pacific Railroad 725 and 731 as well as Southern Pacific Railroad 2873, still painted in the Southern Pacific Santa Fe Railroad merger scheme. SP 2873 is a popular locomotive in the museum's Run a Locomotive program.
