The F7 succeeded the F3 model in GM-EMD's F-unit series, and was replaced in turn by the F9. Final assembly was at GM-EMD's La Grange, Illinois, plant or GMD's London, Ontario, facility. There was no F4, -5 or -6 model; "7" was chosen to match the contemporary twin-engine E7, and was also applied to the new GP7 road-switcher.
The 567B engine was uprated to 1,500 hp (1.1 MW). Some F3s were nicknamed "chickenwire" for the type of engine room air-intake structure along the sides. The F7 (1949) and F9 (1954) were evolutionary: the F7 had improved traction motors, the F9 a 1,750 hp (1.30 MW) 567C engine. A louver arrangement over the vents changed their appearance from ...

Amtrak operates a fleet of 2,142 railway cars and 425 locomotives for revenue runs and service, collectively called rolling stock.Notable examples include the GE Genesis and Siemens Charger diesel locomotives, the Siemens ACS-64 electric locomotive, the Amfleet series of single-level passenger cars, the Superliner series of double-decker passenger cars, and 20 Acela Express high-speed trainsets.
The EMD F3 is a 1,500-horsepower (1,100 kW) B-B freight- and passenger-hauling carbody diesel locomotive produced between July 1945 and February 1949 by General Motors’ Electro-Motive Division. Final assembly was at GM-EMD's La Grange, Illinois plant. A total of 1,106 cab-equipped lead A units and 694 cabless booster B units were built.
A slug adds more traction motors and drive wheels to both use more of the power the mother's engine can produce that cannot otherwise be used at low speeds and provide better braking, without the expense of a full locomotive. [1] A slug is distinct from a B unit, which has both a prime mover and traction motors but no cab. A slug may have an ...
