The EMD E7 was a 2,000 hp, A1A-A1A locomotive designed for passenger transport. It wasmanufactured 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 February, 1945 to April, 1949, and 82 were produced. The 2,000 hp was achieved by putting two 1,000 hp, 12 cylinder, model EMD 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 earlier locomotives made by EMD, the snub nose 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". Some units made before these models were called "shovel nose" or "slant nose" because of their appearance.

Only one E7 survives today. It is owned by the Railroad Museum of Pennsylvania, in Strasburg, Pennsylvania. It is ex-Pennsylvania Railroad E7A #5901. This locomotive has been cosmetically restored, and is indoors, on display.
