Excellent suggestions, Geoff.

I had considered using sub-roadbed half circles of 1/2" plywood cut extra wide, to allow 2 to 3 inch long wood blocks that would be about 4 inches tall, to be used as the support risers on each side of the track. The joints would fall on the longer blocks, with 1 1/2" of the block to screw the abutting circle segments down onto.

Any advantage to using 1/4" tempered masonite, sandwiched together with staggered joints (as with Keith and Geoff's 1/4 inch plywood method)?? Would it be more or less likely to warp or sag than plywood?

And Geoff, since you are modeling the Telluride branch in the first decade, I suspect your helix will become known as "Keystone Hill(ix)" . . .
