Alright got a problem, have an HO scale train and we have a lower and higher leg which both lead into a yard, when we go to bring the train into the yard, thru the lower leg it gets to the 2 insulators that are supposed to be in thir place and the train rocks back and fourth seeming like the currents are butting ends going opposite directions, the higer leg is wired identicle but doesnt rock back and fourth goes straight in, anyone know how the currents would change like that ? or if thats the problem
