Temperature changes can play havoc with trackwork. I was a member of a club (now disbanded) that had the use of a large building at a local museum. Montana has some extremes of temperature and the results showed up every spring when we opened the layout for public display and operation. Track would be bowed by high summer temps and pulled apart by cold in the winter. Don't give up on the layout. I understand that blank doors make good tables for N scale layouts and they should be easy to move from place to place. Jim K
