John Patrick posted:After many years of having my trains in a box I am becoming active again. I have seen many posts on how loud the Fast Track can be. I am planning on using Fast Track on top of 1/2 inch plywood. Layout will be 7 by 11. In researching ways to reduce sound I found a cork floor underlayment that I am thinking would be a good sound deadener for the top of my table. What do you think of this application?
We tried it on the Fastrack modular layout and it does not seem to help at all. The noise is mostly generated by the roadbed and ties themselves acting as a vibrating surface, rather than the traditional way the table makes noise. My thought is that filling the open cavity underneath with RTV will lower the resonant frequency of the roadbed/ties and reduce the sound.
