Final assembly for all F-units was at the GM-EMD plant at La Grange, Illinois and the GMDD plant in London, Ontario, Canada. They were sold to railroads throughout the United States, Canada, Mexico and a few were exported to Saudi Arabia. The term F-unit refers to the model numbers given to each successive type, all of which began with the letter F. The "F" originally meant Fourteen, as in 1,400 horsepower, not F as in Freight. Longer E-units for passenger service had twin 900 horsepower Diesel engines. The "E" meant Eighteen as in 1,800 horsepower. Similarly, for early model EMD switchers "S" meant Six hundred and "N" meant Nine hundred horsepower.F-units were originally designed for freight service – although many without boilers pulled short-distance, mainly daytime passenger trains. Some carriers even equipped small numbers of their Fs with steam generators for long-haul passenger service. On the other hand, Santa Fe maintained a large fleet of fully equipped, high-speed "warbonnet" F3s and F7s built exclusively for top-tier passenger trains such as the "Chief", "Super Chief", and "El Capitan". Almost all F-units were B-B locomotives; they ran on two Blomberg B two-axle trucks with all axles powered. The prime mover in F-units was a sixteen-cylinder EMD 567 series mechanically aspirated two-stroke Diesel engine, progressing from model 16-567 through 16-567D.Structurally, the locomotive was a carbody unit, with the body as the main load-bearing structure, designed like a bridge truss and covered with cosmetic panels. The so-called bulldog nose was a distinguishing feature of the locomotive's appearance, and made a lasting impression in the mind of the traveling public.The F-units were the most successful "first generation" road Diesel locomotives in North America, and were largely responsible for superseding steam locomotives in road freight service.F-units were sometimes known as covered wagons, due to the similarity in appearance of the roof of an F-unit to the canvas roof of a Conestoga wagon, an animal-drawn wagon used in the westward expansion of the United States during the late 18th and 19th centuries. When a train's locomotive consist included only F-units, the train would then be called a wagon train. These two usages are still popular with the railfan community."@en }
