The EMD E8 was a 2,250 hp, A1A-A1A passenger train locomotive manufactured by General Motors' Electro-Motive Division (EMD) of La Grange, Illinois. The cab version, or E8A, was manufactured from August, 1949 to December, 1953, and 421 were produced – 418 for the U.S., and 3 for Canada. The booster version, or E8B, was manufactured from December, 1949 to May, 1953, and 39 were produced – all for the U.S. The 2,250 hp was achieved by putting two 1,125 hp, 12 cylinder, model 567B engines in the engine compartment. Each engine drove its own generator to power the traction motors. The E8 was the ninth model in a long line of passenger diesels of similar design known as EMD E-units.

Compared with many earlier passenger locomotives made by EMD, the noses of the E8 cab units had the appearance of a bulldog's snout when viewed from the side. Therefore, the E7, E8, and E9 units have been nicknamed "bulldog nose" units. Some units made before these models were called "shovel nose" units or "slant nose" units because of their appearance.

Many E8s survive today. According to Andrew Toppan's list of March 5, 1997, 58 survive. See his external link below. One E8 is operated by the Midland Railway, in Baldwin City, Kansas. Privately owned, this unit is ex-Chicago, Rock Island & Pacific Railroad E8A #652. It is used for special events.
