Quote1) is there a ready-made cable that will do this, (ideally, a female-to-female terminal rerailer power cable...You bring up a good question. Mr. Trainman provided a great answer. Here's the but. Bachmann has a connector (2 wire) for what you are inquiring about. Unfortunately, what I have found is that Bachmann only sells them in their Automatic Reverse Loop Module (model 44912). I wasn't able to locate that cable in their parts list. Maybe you might succeed by contacting their service dept and ask for the cable that comes with the 44912-reverse loop. Just note that Mr. Trainman probably provided the least expensive fix to your question.
Hope this helps.







Thought this would be a simple fix, that is, just slip the connecting rod (yellow lined) back onto the worm gear shaft and all would be well. NOT! I put the locomotive back on the track and within say 10 track feet, it slips off again. I tried glue on the back side of the shaft (motor side), but that failed. So I'm at a lost as to how and/or what keeps the shaft connecting rod in place. I don't see any issues with the other shaft and I also don't know or see what's keeping the other connecting rod on the worm gear rear trucks.
