I bought a Thomas the Tank Engine set for my 5 y/o for Christmas, but took the FasTrack out, added a few pieces, and set up a loop around the tree. Naturally, everyone wanted more, and we do have some space, so I grabbed some spare O27 profile tubular track and set up a nice dog-bone like loop that's roughly 6' x 18'. The problem is that our carpet has a fairly tall pile that comes up close to the top of the tubular track. I need a roadbed.
My basement layout has foam roadbed under tubular track, but I don't see that as Tan option. Clearly, the best option is to go buy some more FasTrack, but to replicate the dogbone loop would run about $200. Any other recommendations for a roadbed on carpet central?
