(...) 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)

(...) I'm not a big Train-head, so I'm trying to figure out where the problem is from various bits of this discussion. Is the problem that one pair of wheels is connected to power flowing in one direction and the other is connected to power flowing (...) (20 years ago, 11-Aug-04, to lugnet.trains, FTX)

(...) Ha, I knew I'd get something wrong. Of course it would be the controller getting stressed and not the motor. Either way, I'm not interested in stressing anything I don't have to.

(...) 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)

(...) Hi Larry and Ross, I want to be sure I'm understanding this correctly: The simple act of pushing through the points won't cause the short. In other words, if you push a car with regular wheelsets through the points it won't cause the (...) (20 years ago, 11-Aug-04, to lugnet.trains, FTX)

(...) Note that these deliberate, if momentary, shorts may *possibly* have a long term negative effect on your controllers. This would probably not work well with regular Model Railroad gear, but then it's not designed to take the abuse that kids (...) (20 years ago, 11-Aug-04, to lugnet.trains, FTX)

(...) That, as I see it, is the idea. The point B is always set straight. There may be momentary short(s) when the motor pushes it to curve to pass, but once it is past and stops, switching A then supplies it with current, now in the opposite (...) (20 years ago, 10-Aug-04, to lugnet.trains, FTX)
