N-scale's my usual poison, but see, I have this plant shelf. It's just up there taunting me with its emptiness. It's only 23" and change wide, with about sixteen inches of clearance, but it's a good twenty feet long. It's up far too high to be viewed up close, but it has real potential for some nice mountain scenery with some lit buildings -- the whole landscape+train seen at a distance effect. In this case, I'm looking to watch trains go around, more than I am operations. While I'm comfortable on my rolling ladder for maintenance and all, I don't quite forsee wanting to stand up there for hours. I can do this in N, but HO sized trains would be more visible. Would I be insane to try? Maybe with a short tourist-style passenger setup? I could easily conceal the look of too-small curves with scenery pieces, considering the location, but would it even function? Thanks much.
