Yes, and if you use a map properly, you find this: From http://russnelson.com/#network : Rob Logan found a wonderful poster entitled "New York State Railroad Network". It was published by Frank E. Richards, Phoenix, New York, and copyrighted 1958 (fair use claimed). Prepared by R. J. Rayback, and drawn by J. A. Peterson. I did a five-part scan of it and stitched it together badly (yuck). Still, it's better than nothing. There's a small one (1333x1200, small is relative) and a very large one (6666x6000 pixels, 3MB). Mapmakers traditionally insert a small discrepency into their maps so they can detect derivative works. I believe that I've found an error which is likely their inserted discrepency. They claim that there is a railroad heading east from Pavilion, NY. It would have to cross an impossibly steep hill, and I can't find it on either topographic maps or aerial photos. I contacted Virginia Rigoni, Town of Pavilion Historian on 11/13/2005 and she assures me that the only railroad in the town of Pavilion is the well-known north/south B&O line. -- --my blog is at http://blog.russnelson.com Crynwr supports open source software 521 Pleasant Valley Rd. | +1 315-600-8815 Potsdam, NY 13676-3213 | Sheepdog _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
