The EMD FP9 is an American 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 4 feet (1.2 m) 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.^[1]
