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

Can you show a diagram or picture of the layout. It could be with a switch somehow or reverse loop. Try reversing the feed to the isolated section.

yeah ill take a picture of what we got but how do you reverse the feed? would the power in 2 sections or the insulators cause it to have reverse direction?

Disconnect the track and wire it to the center two toggle points.
connect the track to the sight side of the switch with two wires. Then crisscross a connection to the left from the right side if the switch.
This will change the polarity on the track so you can travel throught the pins depending on the position of the switch.
This is a DPDT switch.

I know zero about your wiring. Go back and check everthing on your wiring. Or go back to a circle. A train running in a circle The top rail is positive when you look at the bottom of the loop the bottom rail is positve. You have two circles going in diff directions. SO with a DPDT you change polarity before the train reaches the second.
