EMD's GP 7 & 9
The GP 7 was EMD's very sucessfull road switcher. It's utilitarian body gave better vision to the operating crew as compaired to the streamlined F3. Making it better suited for freight and road switching service. It was well powered for it's time, but needed more as the competition keep increasing the power of their products. EMD made the GP 7 one way. The only changes were requested by the railroads. I read where you could order a GP 7 with a large fuel tank, giving a look similar to a GP35 frame, which caused a relocation of the air reserve tanks. Most were put on the roof. Unlike the GP 7 the uppowered GP9 was updated in phases rather than make another model. Here is photos of the basic phases.
I'll start with a GP7
