AA was a designator used for several different diesel locomotive types custom built by Electro-Motive Corporation with passenger or baggage space in the same body.
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.
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 locomotives carrying the
AA designation include the Pioneer Zephyr, Flying Yankee, and General Pershing Zephyr power units.
