Hi all, Below is a picture of my layout. I'm wondering how to attach the feeder wires to the track while maintaining separate rail polarity. Along "S" curves, the inside rail becomes the outside. How do you handle the polarity change? Assume rail A is red, B is black. After the S turn, the colors would change and then later down the line the colors won't match. Won't this cause a short? Maybe my pic will explain it better. Look at the top middle part. View attachment 26220 Any help would be appreciated.
