I am busily putting together a track plan for an N-scale railroad based on one of the Kalmbach books. My design is roughly 36 x 72 inches.
Said book uses half inch foam core (aka artist matte board) as the base material. Since this seems kinder on the eye and hand than foam insulation, I am likely to go with this suggsetion. I have used the stuff in other contexts, and it glues nicely, does not really melt at reasonable temperatures, does not flake, and cuts well with an xacto knife.
Does anyone have any comments on this material? The layout will be supported by a rather large flat piece of furniture, so it does not need a lot of structural strength.
Also, does anyone have suggestions on where to get the stuff, either delivered or local to south Orange County, CA?
