EMC AA Diesel Locomotive
AA was a designation 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 No. 7100. MP 7100 was built for service with the Delta Eagle passenger train, which ran between Memphis, Tennessee and Tallulah, Louisiana, and also the Dixie Eagle.
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.
