For what it's worth, my layout is designed to support at least 5 adults up on the "table" for track laying, and scenery installation. I used 3/4 inch "roofing" plywood wit L girder support. Even now, at six foot three and 214 pounds, I can get up and walk on the track portions of the layout for maintenance and cleaning of structures and track.
