I got interested in the GE traction motors used on the Alco and FM competitors of the EMD E-series locomotives: see strings on the Alco and FM forums. EMD used GE electrical equipment on various of its early locomotives (I think they started using their own traction motors with the E-3 series, but that's a vague recollection). Does anyone here know what model or models of GE traction motors were used on early E-units (and other early EMDs, such as the 511-512 passenger prototype boxcabs)? Right now I'd ***GUESS*** 730, since this was the model used on non-dual-service Alco Dl-109, but there are several other possibilities, and different motors may have been used on different units.
