The '''EMC E6''' was a {{convert|2000|hp|adj=on}}, [[AAR wheel arrangement#A1A-A1A|A1A-A1A]], [[streamliner|streamlined]] passenger train [[locomotive]] manufactured by [[Electro-Motive Diesel|Electro-Motive Corporation]], and its corporate successor, [[General Motors Corporation|General Motors]] Electro-Motive Division, of [[La Grange, Illinois]]. The [[A unit|cab]] version, E6A, was manufactured from November 1939 to September 1942; 91 were produced. The [[B unit|booster]] version, E6B, was manufactured from April 1940 to February 1942; 26 were produced. The {{convert|2000|hp|adj=on}} was achieved by putting two {{convert|1000|hp|adj=on}}, 12-cylinder, model 567 engines in the engine compartment. Each engine drove its own [[electrical generator]] to power the [[traction motor]]s. The E6 was the seventh model in a long line of passenger diesels of similar design known as [[EMD E-units]].

Compared with passenger locomotives made later by EMD, the noses of the [[EMC E3|E3]], [[EMC E4|E4]], [[EMC E5|E5]], and E6 cab units had pronounced slants when viewed from the side. Therefore, these four models have been nicknamed "slant nose" units. Later E models had the "bulldog nose" of the F series.

One interesting E6 variant custom-produced for the Missouri Pacific was the model [[EMC AA]].  This was a motorcar-style unit which had only one prime mover and {{convert|1000|hp}}, and substituted a baggage compartment where the other diesel V-12 would have been.  The [[Chicago, Rock Island and Pacific]] owned an equally interesting pair of similar power cars known as the [[EMC AB6]], which were mechanically identical but had boxcabs in blunt noses.  These acted as boosters behind conventional E6A models on the ''[[Rocky Mountain Rocket]]'' train between Chicago and Limon, Colorado, from where the E6A would take the Denver cars north and the AB6 would take the Colorado Springs section of the train south.

==Surviving units==
Two E6 locomotives survive today:

[[Chicago, Rock Island & Pacific Railroad]] E6A #630, was operated by the [[Midland Railway (Kansas)|Midland Railway]], in [[Baldwin City, Kansas]]. RI 630 has since been sold and will become part of a future museum in Manly, Iowa, along with Rock Island E8A 652. Both units have been cosmetically restored but currently are under a mechanical restoration at Mid-America Car in Kansas City, MO as of March 2017.

[[Louisville and Nashville]] E6A #770, built as L&N 450B, is located at the [[Kentucky Railway Museum]], in [[New Haven, Kentucky]]. This unit is for display only, as it came to the museum  without most of its internal parts.
