CBNS bulkhead pulp

Now here's a piece of history in action!
Back when CBNS first came to be they decided to use their own bulkhead pulpwood cars and eventually had a roster of about 20. Not sure of their origins, but they were in service between 1997 and 2002, before being replaced in favor of the more standard CN/WC/AC/IC/ICG/NBSR cars that CN uses. Now that traffic is down and the loading facility has closed in my town, I thought I'd never get a roof shot of a bulkhead pulp car again. To my luck I did and it looks like CBNS is back to using their own cars. Sideways it lickely looks like the TRAX cars they're also using: http://www.railroadforums.com/photos/showphoto.php?photo=38724&si=trax
