At first glance, the General Motors FP7 or FP9 looks like their freight-service counterparts. But on closer examination, the models extra four feet of length can be seen in the space between the first porthole and first louver. This extra space was used to increase the boiler water capacity for the steam generator, allowing the unit to operate over longer distances, matching the unit's fuel capacity without the need for intermediate water stops.
The locomotives popularity is reflected in its sales numbers - 362 FP7s for 27 customers and 93 FP9s for four customers. Major U.S. owners included Atlantic Coast Line, Louisville & Nashville, Milwaukee Road, Pennsylvania Railroad, and Southern Railway. North of the border, Canadian National and Canadian Pacific found the models ideal as did Mexican railroad, Nationales de Mexico.
