The whole layout is designed to be powered by one transformer, either a PW KW, ZW, or an MRC Pure Power Dual. The layout is designed so that they are all interchangeable.
Below are a couple of pictures so you can have a visual. I hope I'm doing this right, it's my first time posting photos here. The first one is an earlier picture and the second one is after I finished the frame and control panel. The transformer just sits on the control panel when in use and is removed before the control panel gets folded up for transport. I was just starting the wiring when I read about TVS diodes and circuit breaker protection here on the forum. My last layout was about 25 years ago and all I used then was what ever my transformer came with. And yes, I do think I have a thing about toggle switches.
