Thanks for all the good suggestions, it would be a long climb up the stairs, 48 scale feet. Maybe I could use a piece of 4" pvc pipe and pretend there is a circular staircase inside like a Lighthouse.
Adriatic, I've never done a thread on the tri level layout, it's a portable layout, the verticals are pvc pipe so it comes apart pretty easy. Held together with gravity and power is feed through a pipe. I use it for Marx trains.
