Module construction as per HOTrak

[lajry]

Here's a module system developed by Dennis Ivison from Garden Grove CA. It uses 2" Styrofoam only for the modules & PVC pipe for the legs. He built his home layout using these modules for his fictional narrow gauge On30 South Pacific Coast RR. His are all 30" by 72" to hold up a lot of scenery & structures. The foam was glued together using "Liquid Nails for Paneling & Molding Adhesive". But if you chose this system the modules could be whatever size works for you. The modules are very strong but are also very light compared to wood or steel frame & plywood ones.
