Okay, it took a while, but I think I finally have an answer for you. From what I can piece together, the A1A-A1A was a much more smooth ride than a B-B or a C-C, the B-B could achieve greater speeds than a C-C, and the C-C had the highest tractive effort.
Hmm. That is strange. Like I said, I don’t know much about railroading, so this is long beyond me.
Well an A1A bogie has only 2/3 the adhesive weight of a C or Co bogie for an otherwise identical locomotive.
I was referring to the fact that the wheel arrangment was called A1A-A1A instead of CO-CO.
But diesels and electrics are not like steam locomotives, where undriven guide wheels are needed for speed and firebox support…
I don’t know much about trains (though i’d like to,) but perhaps it was for efficiency?
