Well, I guess I thought that if your engine is running clockwise around an oval, and then enters a turnout that puts it in the "X" part of the layout which is situated in the middle of the oval, and then follows that leg of the X across the crossroad, and then comes out on the other side of the oval and enters that oval such that it is then traveling counter-clockwise on the oval (i.e. suddenly traveling in the opposite direction on the oval), then that would cause an electrical problem or a stall. I would very be happy to know that I am wrong. :-)
I mean, your engine is suddenly running on the original track, but in the opposite direction.
Does the presence or absence of an E switch have anything to do with this?
Thanks,
