The EMD E7 was a 2,000-horsepower (1,500 kW), A1A-A1A passenger train locomotive manufactured by General Motors' Electro-Motive Division of La Grange, Illinois. The cab version, or E7A, was manufactured from February 1945 to April 1949, and 428 were produced. The booster version, or E7B, was manufactured from March 1945 to July 1948, and 82 were produced. The 2,000 hp was achieved by putting two 1,000 hp, 12 cylinder, model 567A engines in the engine compartment. Each engine drove its own electrical generator to power the traction motors. The E7 was the eighth model in a long line of passenger diesels of similar design known as EMD E-units.

Compared with other passenger locomotives made earlier by EMD, the noses of the E7 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.

A Gulf, Mobile and Ohio Railroad E7A features at the start and end of the 1967 film In The Heat Of The Night.

The only E7 that survives today is owned by the Railroad Museum of Pennsylvania, in Strasburg, Pennsylvania and is ex-Pennsylvania Railroad E7A #5901. This locomotive has been cosmetically restored, and is on indoor display.
