I have a question about the use (or not) of Homosote. I've read numerous conversations here and elsewhere about using it over a plywood base so I know it's recycled paper based, will absorb water, and very dusty when cut. Also, I understand it is a great sound deadening material.
I originally had thought about using foam board of some kind because I have a stream planned for my first train board and thought I could "chisel" then paint the stream on it and have the train track traverse it with a bridge or trestle.
Now I'm confused which approach to choose. One question, I assume Homosote can't be carved like foam board so that's a disadvantage unless I decided just to paint the stream on it without carving it so I would end up with a one dimensional water feature. Also, I've read that foam board is a poor sound deadening material, which to me in counter-intuitive since one would think foam would absorb sound so my question is, if I were to use foam board what should (could) I use to quiet it down, roadbed or cork or something entirely different?
