I found Steve's comment regarding foam insulation on a plywood box interesting. I use a method called domino construction developed by David Barrow, a well known American HO modeller . He builds boxes of either 2 feet x 4 feet or 18 inches x 4 feet. The sides are 3 1/2 inches high. Since I am in Canada, I use rough both sides pine plywood. I use 4'x8'x3/4" sheets. You can get one complete domino from one sheet of plywood, with a 2 foot piece left over.
All my track is glued (called Liquid Nails) on 1/2 inch extruded styrofoam insulation, again in 4x8 sheets, and cut to 2/4 sheets. I apply the Liquid Nails around the edge of the styrofoam (in case I wish to remove it later), and glue it to the plywood.
I am currently installing DCC to the dominos.
After I glued the styrofoam to the plywood, I read that you should not attach track directly to the styrofoam is it amplifies noise. The suggestion was to use cork roadbed on the styrofoam. I will run a test track and if it is too noisy, I will glue sheets of cork under the styrofoam.
I also made a test track by gluing track to a piece of 1foot x 4 feet styrofoam.
