Some interesting GP7 and GP9 notes:

The GP7 and GP9 (also the GP18) locomotives share a similar body that evolved over time. Most GP7s had three sets of ventilation grills under the cab (where the GP9 only had one) and two pair of grills at the end of the long hood (where only the pair nearest the end was retained on the GP9). However, some late GP7s were built with bodies that were identical to early GP9s. Early GP7s had a solid skirt above the fuel tank, while late GP7s and early GP9s had access holes in the skirt. Many railroads later removed most of the skirt to improve access and inspection.
