Update I got some 1/2 simi hard packing foam and made a road bed under some of the track more quiet. I'm not to sure about Zip ties to hold it in place. Layout will be stored on edge when I'm not using it.it seems to me screws would hold it more in place than Zip ties due to it having 5 switches on it.
you thoughts please,
Jess
P.S. Here is my first photo way before foam
