Small world!
I've always liked railroads, and I think it's a shame that they've torn up so much of the old tracks. The D&U is down to less than 10 miles of (barely) usable track, as described above.
Irene also did damage to the remaining scenic lines. The Catskill Mountain Railroad is down to about five miles on the Esopus line, and two miles on the Kingston line.
I do occasional contract photography for a railroad that's thinking about reviving commercial / scenic passenger service from New Jersey, through PA, into central New York, running on the old Erie line (presently owned by N&W and leased to NYS&W). That would be nice.
If they actually do it, I might be able to finagle a cab ride out of the deal. That would be nice, too.
