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.

EMD constructed 3,626 GP9s, including 165 GP9Bs.[3][4] An additional 646 GP9s were built by General Motors Diesel, EMD's Canadian subsidiary, for a total of 4,257 GP9s produced when Canadian production ended in 1963.[3] The GP9 was succeeded by the similar but slightly more powerful GP18.[5]

Design and Production[edit]

EMD designed the GP9 as an improved version of the GP7, with an increase in power from 1,500 hp to 1,750 hp, and a change in prime mover to the latest version of the 567 engine, the 567C.[5] Externally, the GP9 strongly resembled its predecessor. Most were built with high short hoods, but the Southern Pacific ordered a number with low short hoods for improved crew visibility.[5]

EMD built GP9s at its LaGrange, Illinois facility until 1959, when American production was ended in favor of the GP18.[5] GMD production in Canada continued until August 1963, when the final GP9 was produced.[3]

Rebuilds[edit]

There were 40 GP9M units built that are included in the 3,441 units built for United States railroads. A GP9M was built with parts from another older EMD locomotive, either an F unit or a damaged GP7. The use of parts from these older locomotives caused the GP9Ms to have a lower power rating than a GP9. This would be either 1,350 horsepower (1.01 MW) if the donor locomotive was an FT/F2 or 1,500 horsepower (1.12 MW) from F3/F7/GP7 locomotives.

Many rebuilt GP9s remain in service today with shortline railroads and industrial operators. Some remain in rebuilt form on some major Class I railroads, as switcher locomotives although most Class 1 railroads stopped using these locomotives by the 1980s. Canadian National still has many GP9RM locomotives in operation, as of 2016. Canadian Pacific had many GP9u locomotives in operation; however, they were all retired in 2015.

Several GP9s were rebuilt with a 1,500 horsepower (1.12 MW) CAT 3512 and re-classified as GP15C.

The Illinois Central Railroad rebuilt some of its GP9s with their front (short) hood reduced in height for improved crew visibility. The IC designated these rebuilt locomotives GP10.

EMD has rebuilt and continues to rebuild GP9s into what it calls the GP20C-ECO, which is repowered with an EMD 8-710-G3A engine in place of the original 567 prime mover.[6]

Preservation[edit]

At least 23 GP9 locomotives have been preserved at various railroad museums, as "park engines", and as excursion engines according to The Diesel Shop:

Current operators[edit]

The Vintage Locomotive Society currently operates two GP9 locomotives: No. 4138 was built by General Motors Diesel (GMD) in November 1958 for the Grand Trunk Western (which eventually became part of Canadian National Railway). It was donated by CN to the Society in August 2002. 4138 is used on the Prairie Dog Central Railway in regular service and in some charter service. It acts as backup power should steam locomotive No. 3 be unavailable.[9] No. 1685 was built by General Motors Diesel (GMD) in March 1957 for the Midland Railway Company of Manitoba as locomotive No. 2 (which became Burlington Northern Manitoba Limited No. 2, then BNSF No. 1685). BNSF donated it to the society in July 2010. Prairie Dog Central Railway operates the 1685 for both regular service and in some charter service as well as a backup when the steam locomotive No. 3 or 4138 isn't available.[10]
