After two years of using hardboard as a [seemingly] humidity- and
temperature-proof subroadbed, all of a sudden, on my new, "big"
layout, I've got a world-class case of rollercoaster track! 90 feet of
@#%&*! Now what do I do? This stuff was attached to a 2x4
framework attached to the walls with cross-bracing every 2', just
like the smaller layout I had before I undertook this expensive
upgrade. Now I have an expensive piece of @#%&*! Fortunately,
the hollow-core doors I used for the free-standing dominoes are
flat as the prarie, so at least I can run a short train back and forth
about 42'. Woowee! So do I replace the hardboard with (a)
equivalent-thickness plywood, (b) 1" foam, (c) take out the cross-
bracing and attach HCDs to the shelf benchwork with my trusty nail
gun, or what?!?! Maybe I should (c) just chuck this HO stuff and lay
some G gauge track outside. Couldn't be much worse than this
mess!wall1
