(...) Eh, I'm more interested in the electrical puzzle than the trains running on it. Besides, I was considering the possibility that a motor might be set up with two input leads and two output leads that would cause skipped poles if only one pair (...) (20 years ago, 11-Aug-04, to lugnet.trains)

(...) Well yes, but not because the short switched track segment is displaced - the electrical routing is not done through that, but via contacts hidden inside the switch, which don't get displaced. The short is caused by the electrical pickup in (...) (20 years ago, 11-Aug-04, to lugnet.trains, FTX)

(...) Neither. The electrical pickup on the train motor picks up power from both axles. So when one axle has traversed B to the short section of track, the power pickup will connect the outside rail right through the loop, shorting the controller. (...)

(...) I suggest you read up on reversing loops for some background. There are plenty of references out there if you use Google to look. But, failing that, and also for the benefit of the rest of the readership... Consider an ordinary reversing loop (...) (20 years ago, 11-Aug-04, to lugnet.trains, FTX)

(...) Yes, that is correct. The electrical contact is not made by the switching section of rail. I doubt you would cause any damage to the motors - any damage would be to the controller. They seem to be pretty tolerant electrically, but as Lar said, (...) (20 years ago, 11-Aug-04, to lugnet.trains, FTX)

(...) Shorting the power should have no effect at all on the motors. It's the controller that people are worried about. And these should be fine as well. The circuits are short circuit protected for short durration, and as long at the controller (...) (20 years ago, 11-Aug-04, to lugnet.trains, FTX)
