I have an inch and a half of foam insulation board on top of my plywood table to serve as the scenery base for my layout and am using woodland scenics foam for my roadbed. How do I go about attaching the roadbed to the foam, and then the track to the roaadbed.
nick,
if you are ballasting your track, just screw the track to the foam through the foam roadbed, then ballast using a wet-glue mixture. You should then be able to remove the screws and the wet-glued ballast will hold everything inplace, or just leave the screws inplace.
If you really want to go through the hassle of glueing the roadbed to the foam substraight, just use white glue.
