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. GP18s could be customized by their buyers: railroads ordered GP18s with either high or low short hoods, with or without dynamic brakes, and in the case of Grand Trunk Western, with the optional addition of steam generators.Original buyers
