OK, all suggestions greatly appreciated! I am planning to do a layout above my sons bed with basic oval to get him started. Than in time have it run up the wall, around room and back down to platform. My BIG stumper is the Bachmann box said track is 4'3 x 8'6 or some other size just beyond a standard sheet of plywood. I don't really want to join two pieces of plywood and am wondering if anybody knows of any options. This will be set on top of bed posts to make an upper bunk sort of space.
