The '''EMC E4''' was a {{convert|2000|hp}}, [[AAR wheel arrangement#A1A-A1A|A1A-A1A]] [[passenger train]]-hauling [[diesel locomotive]] built by the [[Electro-Motive Diesel|Electro-Motive Corporation]] of [[La Grange, Illinois]].  All were built for the [[Seaboard Air Line]] Railway. The E4 was the fifth model in a long line of passenger diesels of similar design known as [[EMD E-units]].

The {{convert|2000|hp|abbr=on}} was achieved with two EMC model 567 [[V12 engine|V12]] engines developing {{convert|1,000|hp|abbr=on}}, each engine driving its own [[electrical generator]] to power the [[traction motor]]s.

The front noses of the [[EMC EA/EB|EA]], [[EMC E1|E1A]], [[EMC E3|E3A]], E4A, [[EMD E5|E5A]], and [[EMD E6|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 [[EMD F-units|F-units]].

Ironically, the E4 was produced before the E3. Both models were identical, save for the E4 having a [[pneumatic]]ally-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.
