The "last built" PVMR layout has 1.5 inch foam as the top, with 1/4 inch Luan plywood underneath for screws to hold down track, scenery etc. Has worked well, this layout is carried up and down stairs and hauled in trucks with no issues so far and is much lighter than the 1/2" topped Homosote it replaced. We did NOT glue the foam to the Luan so that we could easily replace it if design or damage required. Table top height is 30 inches to allow viewing by our younger, more vertically challenged guests. We also have Plexiglass sides to keep "little fingers" from getting "little people" in trouble. _http://www.youtube.com/watch?v=VD9IuQthNKU_ (http://www.youtube.com/watch?v=VD9IuQthNKU) The 3 rail layout is the one with the new foam top, "S" is now scheduled for rebuild with foam tops as well. HO THOMAS started out on foam.
