The E7 was a 2,000-horsepower (1,500 kW), A1A-A1A passenger train locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois. 428 cab versions, or E7As, were built from February 1945 to April 1949; 82 booster E7Bs were built from March 1945 to July 1948. (Circa 1953 one more E7A was built by the Los Angeles General Shops of the Southern Pacific by rebuilding an E2A.) The 2,000 hp came from two 12 cylinder model 567A engines. Each engine drove its own electrical generator to power the two traction motors on one truck. The E7 was the eighth model in a line of passenger diesels of similar design known as EMD E-units, and it became the best selling E model upon its introduction.
In profile the front of the nose of an E7A was less slanted than on earlier EMD passenger locomotives, and the E7, E8, and E9 units have been nicknamed “bulldog nose” units. Some earlier units were called “shovel nose” units or “slant nose” units.
A Southern Pacific E7A, #6001, is on the point of a train that figures prominently in "The Hitch-Hiker", a popular 1960 episode of the anthology television series, The Twilight Zone, starring Inger Stevens. (According to the narration, Steven's character is said to encounter the train somewhere between Pennsylvania and Tennessee, yet the locomotive's number board shows that the train, #99, is the Coast Daylight, which travelled between Los Angeles and San Francisco.)
Ex-Pennsylvania Railroad E7A #5901 has been preserved by the Railroad Museum of Pennsylvania, in Strasburg, Pennsylvania. This locomotive has been cosmetically restored, and is currently on indoor display.
