The EMC E4 was a 2,000 horsepower (1,500 kW), A1A-A1A passenger train-hauling diesel locomotive built between 1938 – 1940 by the Electro-Motive Corporation of La Grange, Illinois. The E4 was the fifth model in a long line of passenger diesels of similar design known as EMD E-units. A total of 19 units were built 14 A units, 5 B units.
The 2,000 hp (1,500 kW) was achieved with two EMC model 567 V12 engines developing 1,000 hp (750 kW), each engine driving its own electrical generator to power the traction motors.
Ironically, the E4 was produced before the E3. Both models were identical, save for the E4 having a pneumatically-operated nose door passageway in order to facilitate crew movement between units in a locomotive consist.
All the E4s were retired and scrapped by 1964.
Trivia[]
- These engines were only used on the Seaboard Air Line Railway, and the Electro-Motive Corporation (demonstrator).
- The front noses of the EA, E1A, E3A, E4A, E5A, and E6A cab units had a pronounced slant when viewed from the side.
- Therefore, these six models have been nicknamed "slant nose" units. Later E-unit models received the same blunted "bulldog nose" as the F-units.
