EMD FP9


The EMD FP9 is a 1,750 horsepower (1,300 kW), B-B dual-service passenger and freight-hauling diesel locomotive that was produced between February 1954 and December 1959 by General Motors Electro-Motive Division, and General Motors Diesel. Final assembly was at GM-EMD's La Grange, Illinois plant, except for Canadian orders, which were assembled by Canadian subsidiary GMD at London, Ontario. The FP9 was essentially EMD's F9 locomotive extended by four feet to give greater steam generator and water capacity for hauling passenger trains. A total of 90 cab-equipped lead A units were built; unlike the freight series, no cabless booster B units were sold. Regular F9B units were sometimes used with FP9 A units, since they, lacking cabs, had more room for water and steam generators. The FP9 and its predecessor, the FP7, were offshoots of GM-EMD's highly successful F-unit series of cab unit diesel locomotives.

Identification

Just as in the previous FP7, the FP9's carbody is essentially the F9's with 4 feet (1.22 m) extra added a little behind the cab, just aft of the forward truck. Unlike the FP7, the forward porthole window is relocated so that it is better balanced in the space, but there is still more room between the porthole and the first carbody filter grille behind it; it is just less obvious. As on the F9, there is now a carbody filter grille before the window as well.
