@NJCJOE posted:@Richie C. the rear rail is not screwed to the wall. There is a slight gap there. I did the same thing with the standard gauge layout. Some people feel attaching to the wall creates more mass and lessens noise, others feel it generates more noise up through the wall. I decided to let it float.
The wiring will either be run down the center underneath through pipe hangers like I did for the standard gauge, except smaller (see photo). Or, I may run the wiring under the standard gauge and pop up to the O gauge where needed.
I think you're right about letting the rear rail float and the pipe hangers are a nice touch.
