We used Flexxbed under a lot of our Atlas O trackage on our first layout for quietness. But this was on homasote and, frankly, all the hype about levels on sound deadening, at some point, is a matter of degrees at best. So, sound deadening aside, and just from an aesthetics (prototypical - ish) standpoint - is it better to use trackbed or not with Atlas O? Brennan says in his book that putting Atlas O on trackbed is too tall to be prototypical, given tie height. We have track on trackbed and other areas not on trackbed and when ballasted, I have to say, the trackbed areas are quite tall, making the trains seem less weighty and imposing. Thought? Opinions? Thanks.
