Version four is up. I reworked the scripts a bit to reduce the size of the full roster download from about 150K to 120K. Note that the url has changed. The old one is still there, but it will go away soon. Of course you can always access the list via the Friends web site. Click "The Railroad" menu, then "Rolling Stock."
The new script makes it possible for you to bookmark the results of a query--something you couldn't do before. It also corrects a problem in which the Back button didn't work on all browser--something I found to be very annoying.
With respect to the roster itself, I changed passenger car 524 to 517. I don't believe there ever was a 524. The 1999 RFP shows 517, not 524. This version of the roster also reflects the passenger car name changes of 2001.
