Lesson plan
EMC E1
The EMC E1 was an early passenger-train diesel locomotive, developing , with an A1A-A1A wheel arrangement, and manufactured by Electro-Motive Corporation 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. Eight 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 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. All Winton 201A-engined Santa Fe passenger units, including the E1s, were extensively rebuilt into the 80-class E8M engines in 1952–53. They were similar to production E8 models, but derated to so as not to burn out the early traction (axle) motors, which were reused.
