>>7475063>I'd suggest just using cork roadbed and tacking the track to that. Even if you ballast it it should come up pretty easy. You should be able to tack the roadbed to the board without going through it. Pulling up the whole thing and starting over shouldn't be too hard this way.The big thing I'm worried about with nails is that the board isn't very thick and I don't want the nails to come through the bottom if I can help it, I don't know how long the nails for track are. The board is roughly 5mm thick, I'm estimating.
