Gentlemen, thank you for your insights; which are much appreciated. I’m fortunate that my room will be located behind the garage. Growing up my brother had built a 16’ x 6’ lay for our PW fleet. I recall the decibels being high.
My plan is to be able to have a conversation without getting hoarse. I’m anticipating that almost half of the layout will be open grid. I will use 3/4 plywood on the rest. I have access to two 4x8 sheets of homasote. Perhaps I will concentrate it under the track area.
With regards to the use of foam I wanted to use that to carve out trenches, etc. in the track areas and yards.
