OK.... This is N scale... I am about to start construction of my new layout after the first of the year. I have 2 walls in a 12' x 12' room to use, and I can probably come out up to about 3 feet. What I am thinking right now is having one wall be double-decked (20" seperation), with the other being a mountain 'Nolix' area connecting the 2 decks. I need to make it continuous running, with lots of operational opportunities. I'm not entirely sure on what industries will be online yet. Possibly one of the decks may host intermodal ops... Possibly a coal mine in the mountains. Other ideas??? I will be getting DCC to operate this I've decided. I'll learn reverse loop wiring and auto-detection and what-not as necessary. My big problem right now is other than a few sketches of this area.... I'm clueless on getting a trackplan nailed down. Any help or suggestions would be greatly appreciated.
