I don't know but I suspect that Mark Twain road this railroad more times than any other railroad. I have created a page with the route and depots. It runs from New York (Hoboken) to Buffalo, through Elmira. http://twainsgeography.com/content/delaware-lackawanna-western-railroad Some of the route is guesswork. It is derived from Google Earth, kml files from the University of Nebraska and Wikipedia. None of the maps I've seen show the road through Perkinsville even though the map of depots show the location of the depot and I even have photos of what remains of the depot.
