I'm an n-scale novice. I have set up a layout for my son that allows for the train to reverse direction when some of the turnouts are thown. Good in theory. When any of the turnouts are thrown, the track loses power. To isolate the power issue, I disconnected the track so that I only have power to a section of track that contains one turnout. When the locomotive is between the "power" track and the turnout, power is fine, no matter which way the turnout is set. Once the train goes past the turnout, and I throw the turnout to go the other way, I lose power. Anyone have any suggestions?
