Anyone know what the acronym "ABA" stands for in the scale model train world? I just can't seem to find any info...

"Ponyman66" said:To add a little more, the "A" and "B"were actually part of the model designation for the specific locomotive types. For example one of the most common was the EMD "F" unit. They changed the designation with each major advance in the model line, e.g. the FT, F3, F7, F9. NYmustang hit it on the head by describing the "A" as having a cab and the "B" having none. If they had a cab on them you added "A", no cab got "B"in the model number, (FTA, FTB, F3A, F3B and so on).
The letter designation is just to show how they were placed together in the train. They could configure them in with an "A" and "B" unit (AB), multiple "B" units (AB, ABB) or a mix (ABA, ABBA). There was always an "A" unit though.
Probably more than you really wanted to know, right Chris? LOL
