I am building a small permanent layout that is 8 x 12.

I have foam roadbed I will be securing under the track. Do I still need sound board to quiet , or is foam roadbed enough?

Thoughts?

Mine is L Girder with plywood top. My concern is if i use sound board it will get dibits in it from my knees in certain areas, until scenery is finished.

I've walked all over my Homasote and it has no dents, I've kneeled on it plenty as well. 

Thanks John, I thought the Homasote was softer, and might need a little square of plywood to kneel on so not to deform? I had heard someone say that it should also be painted, to protect from moisture.

Our layout was all "L Girder" construction with 3/4" plywood top. We then used Hobby Innovations vinyl "FleXXbed", glued down to the plywood (3/8" thick for main line track, and 1/4" thick for sidings & yard tracks). The Atlas solid nickel silver track was then glued down on top of the vinyl roadbed. It wound up being VERY quiet, and would also support up to 5 adults working on track & scenery projects. All scenery items were glued with Matte Medium, directly to the plywood.
