Have Atlas 0-27 curve track (and 10" straights). Looks really nice, but not cheap compared to getting traditional 027 track

Or if u want something inexpensive, I have Atlas O industrial rail track, new 36" circle, with 4 straight tracks (1 track a terminal track if u want) 16 pcs total, new track, $29.95 plus ship. Its track with its own roadbed. Google Atlas industrial rail track if u want to see what it looks like. I dont have it up on the website, but u can email me if u want it...
thx
