Stop that train!

I have a discussion group on Yahoo for Pittsburgh rail fans and while it is doesn't have a lot of traffic on it I get some real "golden nuggets" from it every so often. One such item posted by one of the members recently was a link to an article about new air brake systems that are being developed that are a hybrid of pneumatics and electronics. It is a very interesting read if you are into the nuts and bolts of how trains function. I decided it was worth posting the link here on the blog.
