I've heard of a new sport route or two that Therien and Brooks had put up, which I think are closer to the main rail-trail -- a little ways away from "Railway Crag Proper." Punshon has also added a few trad lines on the main crag.
A sketch was debated for that crag when the book was published, but there weren't really enough routes at the time to justify the effort. Maybe I'll work on a pdf update over the winter.
Sorry you had a bad time out there
- it's definitely not the greatest crag, but it does have a few redeeming features!
