The EMD E1 was an early passenger-train diesel locomotive developing 1,800 hp, with an A1A-A1A wheel arrangement, and manufactured by General Motors' Electro-Motive Division of La Grange, Illinois. They were built during 1937 and 1938 for the Atchison, Topeka and Santa Fe Railway for a new generation of diesel-powered streamlined trains. 8 cab-equipped lead A units and three cabless booster B units were built. The initial three locomotives were AB pairs built to haul the Santa Fe's Super Chief diesel streamliners, while the others were built as single A units to haul shorter trains. The locomotives were diesel-electrics with two 900 hp Winton 201-A engines each, with each engine driving its own generator to power the traction motors. The E1 was the second model in a long line of passenger diesels of similar design known as EMD E-units.

[edit] Significance and influence
The E1—along with the more-or-less simultaneous EA/EB for the Baltimore and Ohio Railroad and the E2 for the Union Pacific Railroad, Chicago and North Western Railway and Southern Pacific Railroad—represented an important step in the evolution of the passenger diesel locomotive. While the EA, E1 and E2 were each built for a specific railroad, they were largely identical mechanically and were a step further away from the custom-built, integrated streamliner and towards mass-produced passenger locomotives—a step achieved with the E3, E4, E5, and E6, EMD's next models. These locomotives are definitely related in an evolutionary manner with all EMD's future passenger models.
[edit] Styling
The EA/EB and E1 featured largely identical and innovative styling showing the influence of the Electro-Motive Corporation's new buyer General Motors. While mechanically they had much in common with previous, experimental EMC locomotives, GM understood the importance of looking new and exciting, not merely being technically innovative. This basic "slant nose" style was continued in the subsequent E3, E4, E5 and E6 models, while a more "bulldog nose" style was tried in the E2 and a style somewhere in between was used for the E7, E8 and E9, as well as the freight diesel cab units. It could fairly be said that the overall styling influenced passenger locomotives around the world.
[edit] Numbers and assignments
Each E1 was initially ordered for and assigned to a particular train. The ATSF practice was to give all locomotive units in a set the same number, distinguished by letter. The lead unit was designated 'L', but this was not carried on its numberboards. The second unit was 'A'; subsequent units were 'B', 'C', if present. This numbering was part of the railroads' ultimately successful campaign to convince the railroad unions that a multiple-unit diesel locomotive should be considered one locomotive of several parts (and thus needing only one crew) rather than multiple locomotives requiring multiple crews under union agreements.
