I was recently photographing Metro North equipment in Dover Plains, NY along the ex-NYC Harlem Division. I was in the area of the Pleasant Ridge Rd crossing when I noticed two pieces of old rail that had been cut, and possibly used at one point as a fence post. One section was marked "Pat 1890", the other piec had markings, but were too difficult to make out with the layers of paint and rust. Here is one photo of the rail.
