Reply to "Fastrack vs Realtrax"

I'm using Fastrack on my layout with O-36 curves except 2 places where I'm using Realtrax O-31 curves inside the Fastrack curves using the Fastrack Transition piece combined with the Realtrax Adapter piece to connect together.  I use 1/2" thick black soft foam with 1/2" overhang both sides of track. I foam glue the foam to the green matting on the layout or painted plywood on elevated sections and foam glue the track to the top of the foam. No screws used to hold track down reduces the Fastrack rumble a lot. Pleased with the results so far as I slowly remodel the layout. Fastrack should had made an O-27 instead of O-31 so it would had fit inside the O-36 curve track. I totally prefer Fastrack over the Realtrax.
