I am building an around the top of the wall system using pine boards. I am not planning on put any thing under the track and just lay straight on the pine boards (no ballast or track underlay) I have read many suggestions on securing track. It sounds like a lot of users like the "caulk" method.

1. Do you think caulk will work for this design.

2. Regardless of securing material where do you lay the glue/ caulk. Just spot here and there, whole track?

Thank you.

Does anyone make a free standing trestle for G scale set? I have a top of wall track system and want to put a trestle across room opening where there is no wall. So this would be a trestle that can span the gap and be able hold the train weight by itself.
