They all appear to me to be the same type of car.. I thought they were for cattle or something, not that I know much about anything rolling stock beyond what we put tanks, HMMWV's and shipping containers on. But I was told they are all clearly autoracks for cars.
So I would say they were all casualties of the recession which has hit the auto industry hard.. except I still think these have been in place here longer than the recession has been official at least. Still is good theory, but I just wonder why it makes sense to leave them here for so long. I guess anyplace is as good as another though I would think there would be better places to minimize depreciation. No desert for rail cars like they do with planes I suppose. Is CSX getting paid rent?
