The official description provided by the manufacturer.
Liking the performance of their EMD F units, Santa Fe wanted reliable road switchers that could provide better visibility and share components with their other EMD brethren. Between 1950 and 1953, they ordered 244 GP7's. During the 1960's, Santa Fe started to repaint their fleet of GP7's into a more simplified scheme to help on paint masking costs. They were the only purchaser of a small batch of GP7B's, and were usually mated to a like road numbered A units. By the 1960's, they could be found running with other units in switching assignments. In the 1970's, the fleet of GP7's would end up being rebuilt into "GP7u's" with fully rebuilt cabs, electrical components, and prime movers. The B units received cabs in the process. Since Santa Fe was known for changing out spark arrestors, we included them in a poly bag for the modeler to install to match your modeling era.
