I thought I'd share this with you, I just finished putting this room together today.
This may not be perfect to some people, but I bet if you're traveling you would love to have a room like this. However, this one in not available. I have converted my train room into a guest room. We're putting this house on the market this summer and I wanted to leave the ceiling layout in place, hoping a train guy would want to buy our house. The ceiling track is O-27 with 42" curves.
It's located in St.Augustine, Fl.
