EMD E9
The E9 is a , A1A-A1A passenger train-hauling diesel locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois between April 1954 and January 1964. 100 cab-equipped A units were produced and 44 cabless booster B units, all for service in the United States. The E9 was the tenth and last model of EMD E-unit and differed from the earlier E8 as built only by the newer engines and a different, flusher-fitting mounting for the headlight glass, the latter being the only visible difference. Since some E8s were fitted with this, it is not a reliable way to distinguish the two. The E9 has two , V12 model 567C engines, each engine driving one generator to power two traction motors. ==Engine and powertrain== The E9 uses twin 12 cylinder 567C engines developing a total of at 800 rpm. Designed specifically for railroad locomotives, this Roots-blown, naturally-aspirated 2-stroke 45-degree V-type, with an , bore by stroke, giving displacement per cylinder, remained in production until 1966. Two D.C. generators, one per engine, provide power to four motors, two on each truck, in an A1A-A1A arrangement. This truck design was used on all E units and on MP 7100 and CB&Q 9908 power cars. EMD has built all of its major components since 1939.〔Pinkepank (1973), pp. 13, 26, 106, 124.〕〔Ross (2003), pp. 273-274.〕
