Jerry, thanks for the kind words. I'm building a Cal (Rio Grande) Zephyr piece by piece as Atlas O delivers the cars. The newly released baggage car is arriving today or tomorrow.
I'd don't have an accurate layout diagram at the moment. Like you I model two roads. Mine are Uncle Pete and the Grande. When I switched from 3 RS to 2 rail a while back I made the decision to have a much simpler layout for many reasons. It's a simple point-to-loop-to point around the walls shelf layout modelling only the right-of-way to keep it narrow so there's lots of room for buddies to hang out in comfort while running trains, watching train videos or football or whatever. The room is 32 X 17 with an L at the entrance. Modest size for O scale.
