Module construction as per HOTrak

Thanks for adding that. I have a friend who built his home layout in a similar fashion, using just the foam and steel studs.

If your modules are going to be transported to a club or display, the wood frame protects the foam, and the modules are actually boxes together in pairs so the "good sides" face inwards.

To lighten my design further, the 1/4" ply could be replaced with the 1/8" door skin or luan, and it could also be used for the sides. By gluing the foam to the support panel, it becomes incredibly strong.
