lightweight modules

[Anonymous]

I am building my third layout in HO scale and after several moves and less than successful layout moves, I am interested in building a lightweight layout using foam board or the like, allowing for modular construction. I like the Woodland Scenic mod-u-rail system but it seems very expensive.

Does anyone know of a way of building lightweight modules that are strong enough to move, yet easy to build. I am thinking of using 2" foam for the base, but am wondering what to support it with to allow for strength and attaching the modules together. Any help would be appreciayed.

Maybe these will help.

I know it doesn't answer your question exactly, but it might get you where you need to be.

See http://www.railwaybob.com/Modules/ModConstr/ModConstr01.htm for the best instructions I've seen on modular construction so far. You could certainly use 1x4 instead of 1x6 for the frame at the cost of some underneath space for wiring and switch machines. Another technique is to glue strips or blocks of !/4 inch plywood under the foam in strategic locations for trunout actuating devices, wire tie points, and the like. On top, just add foam to get higher scenery and/or track. To get lower than the track, carve away into your 2 inch foam. I use Homasote on top of foam to hand lay track, but plenty of folks use flex track on cork roadbed both glued with latex caulk. Last, but not least - measure your vehicle to determine your maximum module length! My mini-van and Explorer both take 75 inches maximum.

Besides a large home HO layout, I've built a bunch of Ntrak modules, with a variety of construction method. So far, the best overall for durability and light weight has been a 1x3 frame, 1/8" plywood over that, and 1" foam over that. 1" PVC for legs.

Thanks for all the responses. Now I just have to get out of my armchair.
