you guys, it works.
It works, and physics tells us it does, especially if it has a rubberish or foam backing, (closed cell would be best). For me personally, being in a climate where temps swing greatly and humidity can reach 85% I would be concerned that it may start to smell. Fyi, carpet also works great underneath an outdoor pond liner.
For me, acoustic ceiling tiles work great and don't off gas like homosote does.

I also went the acoustic tile route, knowing that I'd be super-e!evating the curves. The tile doesn't give under the irregular pressures needed to attach the track firmly to the roadbed. When angled as such with no firm support the curve tends to kink at the track jointsjoints. Tried this with Atlas track and the commercial foam underlay with horrible results. Rather than banking with wire, which can eventually dig into the tile, I use strips of cork under the outer rail.
Aside from this, I just can't source Homasote in my area.
