Very interesting find. Any idea on what year all of that was abandoned?
While its not narrow guage, up in the upper penninsula of michigan, near Marquette is some old remains of a couple train cars, and various other railroad equipment, along with some old trackage. the old railbed runs right along my familys property up there (my grandmother used to hop the train into town every morning when she was a kid, to go to school, and my great grandfather was an engineer). When I go up there in a couple weeks for a wedding, I will snap some pics.
