I'm not, but I caught a couple of big depressed center cars recently. The smaller car (only a 12 axle) was hauling a transformer through St. Paul, MN.
The larger 16 axle car, KRL 16801, is a pretty new car, designed to haul up to 810,000 lbs! It was waiting at the Rice's Point Yard in Duluth. I'm guessing a large load is inbound by ship to the Port of Duluth.
