2I can see the lure of some of the Atlas, Ross, and Gargraves realistic looking track. I like the Fastrack for several reasons, but I'm sure it makes some more noise. On the 1/4 inch indoor/outdoor carpet, it's quiet enough for me...it's quietest if you run prototypical speeds.
The quietest I ever heard was on tubular at a train meet. I think it was 027.
