I have seen those. What a great series of photo's. I love the shots of the CNW Proviso yard....boy has that changed now with it being such a large intermodal facility.....still large but lots of containers and chassis now, I used to be in there all the time when I was driving a semi.....all you hear are the retarders from the hump yard activity. Thanks for posting the link Jim...I lost it. I'm going to save it now.
