I have used Trex on my elivated railroad with PETS frames for 4 years now.
The Trex has been outside year round. I live in Northern Ohio with summer
heat reaching the 90's and winter time down to zero and below (brrr). I
have had no proble whatsoever with the track bed. There has been no problems
with sags and best of all, I have not had to do any maintenance on the bed.
I strongly recommend it. (I have no ties to Trex.)
