Happy New Year to Derrick and all

I only know about putting asphalt on top of abandoned
tracks.  Didthey ever put concrete over it?  Penn Ave
downtown and the others I mentioned had removed the
abandoned rails.

PRC used concrete on PRW on 42 Dormont with the
rail sticking up a little.  I liked that.
