Matt and George, the track is PECO bullhead rail ,O gauge 2 rail. Nickel Silver rails and UV resistant plastic sleepers or "ties" as you guys in America call them.The track thats been down for a couple of years is as good as the day it was laid. The bulk of my G scale layout was also Peco G scale nickel silver track ,great stuff and far better than any other make I experimented with by far .
Thanks. I'm hedging my bets on home layouts and looking for various alternative track brands should I have to build outdoors.
