EMD E8
The EMD E8 is a , A1A-A1A passenger-train locomotive built by General Motors' Electro-Motive Division (EMD) of La Grange, Illinois. A total of 449 cab versions, or E8As, were built from August 1949 to January 1954, 446 for the U.S. and 3 for Canada. 46 E8Bs were built from December 1949 to January 1954, all for the U.S. The 2,250 hp came from two 12 cylinder model 567B engines, each driving a generator to power the two traction motors on one truck. The E8 was the ninth model in the line of passenger diesels of similar design known as EMD E-units. Starting in September 1953, a total of 21 E8As were built which used either the 567BC or 567C engines. In profile the front of the nose of E7, E8, and E9 units is less slanted than earlier EMD units, so E7/8/9s (and their four axle cousins, the F-unit series) have been nicknamed "bulldog nose" units. Earlier E-unit locomotives were nicknamed "slant nose" units. After passenger trains were canceled on the Erie Lackawanna in 1970 (excluding their commuter service, which the State of New Jersey subsidized starting in the late 1960s), the E8s were re-geared for freight and were very reliable for the EL. These units were on freight trains until the early years of Consolidated Railroad Corporation ("Conrail"). Amtrak used 148 E8As, 3 E8AMs, and 5 E8Bs, these all being retired between 1975 and 1985.…
