The basic design followed most diesel switchers with the addition of a short hood instead of an end-cab. The hoods were also full height to better accommodate the diesel engine and mechanical and electrical components. In 1954 EMD upgraded the GP7 to become the 1750 horsepower GP9. Externally the first GP9s were virtually unchanged from the last GP7s. Later versions would include different louver arrangements and the last ones would come without the frame skirting. The GP9 was available with all of the fuel tank steam generator and dynamic brake options as the GP7 including “torpedo tube” air tanks mounted on the roof. Many railroads chose to rebuild their GP7s and GP9s for continued service. Often times it was cheaper to do this rather than purchasing brand-new locomotives.
