Bob, I'd like to keep the board relatively lightweight so i like the idea of using the foam. 1) What is the best way to carve it without making a huge mess or destroying it?
Also, my two loops will go through the tunnel (with minimal space between them but enough to have 2 trains safely pass each other). A few more questions.... a) Would you put a middle support of some sort between the tracks in the tunnel? b) Is the foam sturdy enough to support the train overhead c) what do you use over top the sides of the tunnel (wood, cardboard, another piece of foam) to enclose it?
I really appreciate your comments and especially the pictures. Curious, how did you make the stone sides on your tunnel? Thanks,
Bob
