AA was a designator used for several different diesel locomotive types custom built by General Motors Corporation EMC/GM with passenger or baggage space in the same body. This locomotive is listed as class AA-6[1] by R. Craig, and the designation is logical as the locomotive is described as "half an E6" in the Second Diesel Spotter's Guide.[2]
One such was a single locomotive built for the Missouri Pacific Railroad, delivered in August 1940, numbered #7100. MP 7100 was built for service with the Delta Eagle passenger train, which ran between Memphis, Tennessee and Tallulah, Louisiana. Note: Missouri Pacific ordered all their 'E' units with portals instead of square windows like most of the E series from the EA to E7's. This was the only MoPac unit with square windows (on the baggage door).
Since the two-car train the unit would have to haul was comparatively light, the AA was built with only one 1,000 hp EMD 567 V12 prime mover, and a baggage compartment where the second diesel would have been.
Other EMC/GM locomotives carrying the AA designation include the Pioneer Zephyr, Flying Yankee, and General Pershing Zephyr power units.
See this site for three excellent photos of the 7100 pulling the Delta Eagle along with a detailed description of this unique train.
