The ugliest locomotive. the ALCO RS-1 (1941), changed railroading.[1] This introduced the basic design of a narrow central section with railed walkways and a cab offset from one end. Worked equally well going in either direction. Good maintenance access from the walkways, where doors opened on the equipment. Could be used for both switching and road trips. No attempt to make it look cool, or impressive. Just useful.
General Motors Electro-Motive Division introduced the GP7 in 1949, which was a solid product of which thousands were built. Looked much like the RS-1 After that, most Diesel-electric freight locomotives followed the same pattern, and still do.
