350 examples of this locomotive model were built for American railroads, 40 units were built for Mexican railroads, 12 were built for export to a Brazilian railroad, 2 were exported to Peru, and 1 was exported to Saudi Arabia.
Design and Production
The GP18 in many ways resembled its predecessors, the GP7 and GP9. It was designed nearly identically to the two previous models, but differed in having a metal grid over its radiator shutters, while the GP7 and GP9 instead incorporated a design described as looking like "chicken wire". Additionally, the GP18 had 50 more horsepower than the GP9, for a total of 1,800 horsepower.
