OOPS!! Hit the'enter key too soon..anyway, when you hook the pit wiring up, you might have to swap polarity on it one time to get the bridge to match your main line track coming in. Get THIS set up right. When you add tracks around the pit, set THEIR polarity by matching the direction on the turntable...(I.e...Set turntable bridge once to match main line coming in, then set other tracks from bridge. When the bridge is spun end -for-end, the ring rail setup will automatically swap polarity on the bridge for you. (If you're DCC, just wire an autoreverser between the main power and the bridge rails.) Hope that helps! -joe
