The A1A trucks used under the PA series weren't QUITE the same as those used under the Dl-100 series, but they were similar: the wheelbase of the PA truck was only two inches greater than that of the Dl-100 truck. And I think the 726 traction motor (used under the majority of Dl-100 units built) probably had the same dimensions as the 752, so probably the motors could be switched between the two types of truck. In principle, would it have been possible switch trucks between a PA and a Dl-10x? Or is there some unobvious difference which would have made them incompatible?
And-- assuming it was possible-- did any railroad (in particular, one which had sizeable fleets of both locomotive types and limited cash to pay for spares…) ever in fact switch trucks between the two types of locomotive in the course of maintenance?
