I think I'd have to break down and do a loop around the top of the wall. I'd consider a gauge that had some sort of magnatraction, so I could run em on the road.
I don't know if you are talking about the ones that are travel trailers or the larger ones. My layout is in a 10 X 12 building (no wheels) and I have it as a single level. It is along both sides and the back wall. The door is dead center on the front wall. Visit my railroads website (http://gdrinc.com/Railroad) for more info. Gary
Got to be Z scale, of course, in the attic. But they would look great in the middle of a G scale garden railroad.......
One of those small trailer houses just cries out for some Ntrak modules. I mean, c'mon, it's already a trailer. Perfect for hauling them to the show.
Keep in mind you are also living in this "house". Maybe one of this rigs on pullies that hangs from the ceiling.
