MIND BLANK. NEED HELP. This space is about 2' x 2' and is part of my N scale layout. Don't even bother asking what I want, because I change my mind a million times. The nearby part of the layout is still undecide, but most likely a steel mill, rolling mill, or power plant will be there. I just put a right hand switch and a piece of flextrack branching off of the main into this area. Era is 80's through today. Pennsylvania for locale.
