EMC E4
The EMD E4 was a 2,000 hp, A1A-A1A passenger train-hauling diesel locomotive built by the General Motors Electro-Motive Division of LaGrange, Illinois. All were built for the Seaboard Air Line, who purchased fourteen cab-equipped lead or A units and five cabless booster B units.
The 2,000 hp was achieved with two EMD model 567 V12 engines developing 1,000 hp, each with its own generator to power the traction motors.
The cab version had a cab, or crew compartment. The booster version had no crew compartment, and therefore, no windshield. There were simple controls inside the unit to move the booster around in a yard. Boosters were not to be occupied while on the road. They were built to save on the expense of building the crew compartment.
Compared with other passenger locomotives made by EMD before and after these models, the noses of the E3, E4, and E6 cab units had pronounced slants when viewed from the side. Therefore, these three models have been nicknamed "slant nose" units. Some units made before these models were called "shovel nose" units because they looked like old coal shovels. Some units made during and after these models were called "bulldog nose" units, because they looked like a bulldog's snout.
No E4 survives today.
