The Southern Pacific GP9E and GP9R are rebuilds from EMD GP9 diesel locomotives that were built by General-Motors Electro-Motive Division for the St. Louis Southwestern Railway (also known as the "Cotton Belt Route") and the Southern Pacific Transportation Company.

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] .

Starting in 1970 with #3424 all existing GP9's were rebuilt into GP9E's and GP9R's. see the SP GP9 Overview for Magazine/Book References and available models.

Starting in 1970, the SP GP9's entered various rebuilding programs, emerging as rebuilt GP9E's and GP9R's while the SSW rebuilds began in 1974. Some were renumbered and reclassified as heavy yard switchers .
