Re: Traction motors

John,

The model from the builders plate on the 15 and 19 should be something like "B-B 94/94 4GE733". I assume they are the ng version of a 44 tonner with CAT D1700 engines.

The 130 and 140 should be something like "B-B 108/108 4GE(733/747/???)" or maybe just "U4B". I don't remember if they still have their builders plates. I did have a legal ride on them one trip to the mine and saw them several other times over 25 years ago, but my slides are in storage 1,000 miles away right now.

I've seen the traction motors from the 111/112/113. They are huge, the same size as a 752 but narrowed for 36" gauge. I can't remember if they were 761 or 763.
