I ran across this site and thought y'all also might enjoy reading it. Lots of interesting information and links. http://www.kinglyheirs.com/NewYorkStateRailroads/NewYorkCentralHome.html#.Vy5UuVgrLIX
I have seen that strange layout before, from someone who did some obscure history of the Little Falls and Dolgeville part, long gone from the Mohawk Division. I think it's some old software program. I should talk, eh, just using my own html code for my site, and haven't updated it in a long time.
I just tried it again. No hit on my antivirus. But it did flip me over to another non-railroad page. Some sort of redirect is buried in there.
