Plywood is fine....if you have a piece then use it. Your plan to make it portable is perfect for a switching layout. If you still need to get material to use as a platform....the soundboard (celotex) Nmaniac was refering to costs only half what plywood costs....and it's very lightweight...Not quite as stiff as plywood though....but you can brace it with cheap 1" x 2" pine sticks.I'm considering making a semi-portable layout, the base will just have track on it, and would be stored in a closet when not in use. When operating I will place it onto a table, and then put any buildings in place, power it up, and start running trains. If this isn't a good idea then I'm not sure how I can make this work, I'm still a big fan of model railroading, but my friends and parents aren't the biggest supporters and I'd like to keep my hobby as private as possible. Something like a door would be too big, what about a plain old piece of plywood?
Sometimes a lumber yard will have scraps or smaller pieces of plywood or celotex for cheap. Or a construction site dumpster might be full of usable stuff but I always ask someone before taking anything. Just some ideas here.
