I'm in the process wiring my layout, I have 2 reverse loops and on each loop there is a turn out, one to a turntable which will have an AR1 controlling it, the other RL turnout goes to a yard area. Each reverse loop is controlled by its' own controller (PM42) sections set for Auto-reversing. My question is, if I'm operating a switcher in the yard area and a freight loco enters the Reverse loop on which I'm running the yard switcher and the entering freight loco is entering the loop with the opposite polarity and the auto-reverse switches, what happens to my switcher in the yard, same goes for the other loop with the turntable's entry and exit rails?? I was told that nothing will happen?????
