You are looking at a lot of 4 sections of Lionel track 6-65523. This is the full 0 gauge tubular track (NOT the smaller, thinner 027 or the roadbed-based FastTrack).
It is the taller, thicker gauge tubular track with the black ties. Each section is 40".
CONDITION: C-6 very good, used. Looks good. Will make sure all pins are in for you before shipping. May show some oxidation from sitting around.
