Trainlover9943 posted:On the prototype SF FT sets how were they configured? In the photos I looked up (quick google search) many of the pictures I found (mostly the freight painted colors) were mainly ABBA, however I did see a few pictures of an ABA and one of a ABB set. As a general rule, what were they ran as ABBA or ABA?
There really was no "general rule". It all depended on the HP requirements for that given train, at that given time. Also, unlike most other railroads, the Santa Fe FT units had couplers on both ends of the "B Units", instead of the semi-permanently draw-bar connection between the "A Unit" and the "B Unit".
