With hundreds of F-units on the roster, Santa Fe owned numerous variations of the type. Two unique versions are represented in this release.

Units 261L and 265C are F7A locomotives delivered without stainless-steel grilles, giving them a unique appearance somewhere between that of an F3 and an F7. They are painted in the blue-and-yellow freight scheme.

Units 257L and 257A were among a handful of true dual-service units on the roster. Santa Fe owned several freight units with steam lines that could be used as emergency passenger power- but the 257 was distinctive in that it carried steam generators in the B-units. The units were still geared for freight service (65 mph), but often found themselves pressed into passenger service as well. They are painted in the cat-whisker scheme.

PROTOTYPE SPECIFIC INFORMATION

EMD F-units were a line of diesel-electric locomotives produced between November 1939 and November 1960 by General Motors Electro-Motive Division and General Motors-Diesel Division. 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, and Mexico.

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 (main line) diesel locomotives in North America and were largely responsible for superseding steam locomotives in road freight service. Before this, diesel units were mostly only built as switcher locomotives, and only used in rail yards.

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.
