I'm planning my first in over 25 yrs. A 14x10 with a double main, small yard etc. Calculations put me @ 200+ feet of track. I plan a cookie cutter bench with plywood sub-roadbed. In flat areas I'll use Pink Foam. Like most I'm on a budget. :funny: A 1/4" pink foam roadbed is 1/5 the cost of cork or Woodland Scenic bed. Homasote is even less expensive but would require more/messier work and I'd have a 1/2" roadbed. What are your thoughts on the 1/4" foam Roadbed?
