I'm going to install my outdoor layout this spring and need info on the best way to lay the track in the North East. Temperature ranges from 5 to 100 Degrees f. here. I'm worried about expansion and contraction tearing the track and lightly cemented ballast up. Any one with experience in this please share your thoughts. From what I have read most outdoor layouts take about three tries to get the track laid right so it will last! I'm hoping with your help to get it right the first time.
