Reply to "Thoughts on traditional track options/AF display progress"

I like the rubber roadbed and per Gilbert's instruction manual you only tack down the roadbed not the track so sound will not be transmitted.  It also looks good.  If you were going to do the extra ties you may consider Gar Graves track. It looks good especially when ballasted and can be flexed into larger curves than Gilbert made.  Gilbert made their own custom track for many of their displays to have larger radius.
