OUT OF PRODUCTION.
You are looking at a lot of American Flyer two rail S scale track, the traditional style dating back to the mid-1940's, BUT THIS IS THE NEWER MANUFACTURE BY LIONEL IN 2011. IT IS IMPOSSIBLE TO FIND THESE DAYS as Lionel has transitioned to its FastTrack style.
This is the newer release with American Flyer Trains stamped on the black ties. It really is the best of both worlds--same mold/style as the original you remember, but it is more current manufacture. This is what you need to match up to the original track or just to LOOK like a shiny example of the old stuff. And you know how much your Flyer likes new/clean track!
CONDITION: Used. These sections look like new. They almost look unused EXCEPT only one of the holes for nailing the track to the layout on only one tie on each section has had a screw through it. Hard to notice. Otherwise looks like new to new. Clean. May have been used as a display track rather than actually on a layout. Mostly shiny with a few signs of use. Newer production--looks just like the original, from the same mold, but new manufacture.
