Thanks brianelO27, I learned something new, I never saw WBB branded track - maybe those were the ones I bought a few years ago with nothing stamped on the ties.
IMHO the demand was killed when Lionel and others stopped putting O27 height track in their starter sets, a huge volume of production I'm sure. That then led to the slowdown of track sales for starter layout expansions.
If the tooling is out there I think the current demand is here for at least a couple large limited runs.
I'm glad I started hoarding straights, wide radius curves and switches a few years ago when prices were low and the availability was high
