This is kind of what I had in mind! Here’s what one cool Geekdad did in his kid’s bedroom. Reader Cassie Rousseau writes to us: “I saw this in another house. The train track ran around near the ceiling of the room, through a “tunnel” in the closet and out again. I thought it was very clever! Could be adapted and expanded with bridges, trees, etc. I think it’s a great way to have a model train set without taking up all the floor space in a room.”
