Yes, a layer of 2" insulation foam board will be adhered to each modular section of the deck. I will do so after completing the build of at least 3 yard sidings. Right now I am working on building 2, or rather adding a second to the existing first siding. See this thread for a better understanding: Yard Siding Mock Up
The foam will be attached with Velcro because I will have to remove it when I change the layout design. This helps with drilling new holes in the wood layout deck to run wiring through. Once the holes are drilled in the wood deck it is very easy to drill or cut the holes in the foam.
After I add the foam I am going to add a neutral color scenery mat, probably the “desert” colored one.The holes in the foam will be covered by the scenery mat. To run the wiring trough the mat I will simply cut little slits.
The scenery mat will be attached to the foam with the clear 3M Command adhesive strips. They have proven to be very effective at holding the Atlas snap Track in place. Each section of the Atlas track you see on cork bed is glued with Liquid Nails Silicon Adhesive. The cork bed is cut to the length needed then glued to the track. Because the track will slide apart at the rail joiners when the train rolls over it I am using the 3M Command strips to adhere the cork bed with track glued to it to the layout. I discovered this is still a lot cheaper than using Bachmann Ez Track that you see for the mainline and most of the passing siding.
From what I have been told I may be the first one on MRR to design my track sections in this manner. As such I am going to post an instructional thread on the methods I use to d
