@Chuck K posted:People always talk about the noise of AF FastTrack, but I have a layout comprised of it, and I have no issues with sound. Perhaps these folks are screwing it down directly to a wood surface, something I wouldn't recommend doing with any type of track.
Let's not forget, S model trains have less mass than their O gauge cousins. The S FasTrack and S-Trax systems also have solid rail and smaller "resonant chambers" verses O gauge FasTrack. All of which will have some effect on noise levels.
