16 sections for a complete 54" diameter circle
You are looking at a lot of 16 pieces of Lionel track 6-65554. This is the full O gauge black tie tubular track, but it is a WIDER diameter for your circle. Instead of a 31 inch circle, the 054 makes a 54" circle.
It takes 16 sections to make a COMPLETE 54" circle, and that is what you get here. It matches up to the most common, traditional sized O gauge track in Lionel sets past and present (until FastTrack), USUALLY the track with black ties. It does not match up (height wise) to the smaller 027 type track. If you have questions about this, just send me a message!
CONDITION: Seven sections have light green paint on the UNDERSIDE from layout; nine have gray paint on the underside. All pins.
