I assumed I'd use either 1/2" plywood or 2" dense foam on top of 1x3 framing. I assumed the hollow doors might sag under the weight they'd be supporting in terms of scenicked layout levels and the trains themselves?
The hollow core doors will work. I would try to go with a 1 3/4" thick door, instead on a 1 3/8" door. Also if you do use the doors, be sure to paint them on both faces and all four edges.
