The return loop worked good yep And I know about auto reverser But I am looking at the new track plan and I don’t see a reverse loop I am going to study it more tomorrow

I hear ya. I had the tracks all removed to be a loop, what I’m doing with now is just unplugging entire top Kato feeders and redoing the setup. I have 3 of the digitrax ar1 but they have a dial to adjust sensitivity. When you run a Kato through you need one end of the dial and when you run BLI you need the other end of the dial. So I have picked up a dcc specialities reverser. The way my layout is has a reversing loop at each end. I am trying to make it into a loop with a branch line to a reversing loop.
