1. I only see two reversing loops in this. Although one has a wye and parallel tracks on it. So you could wire it as more than 2 depending on operational desires.I've seen this layout over the years on the web. I have contemplated constructing this one. But I have a question about reverse looping galore on this. That would be an issue with DCC? Maybe I'm misinterpreting the track plan. Picture is all I have to go on.
