Huge LOT of over 5 pounds of HO gauge TYCO "all steel" track - mostly TYCO but it might have some other stuff mixed in. Lot includes curve, straight, rerailers, power tracks, a couple (untested) switches and some other specialty tracks (like an X track). 75% is in very nice overall used condition but a few will need more cleaning than others and also some have a broken tie or two. At my best guess you should end up with at least 100 nice track out of the lot. I stopped counting at 125 track and then tossed even more in to completely fill the box.
