I do know that the NC&StL went to Gadsen, AL which was the sight of a large steel works. I think it was called Republic Steel. Anyway, I think the container gons hauled calcium carbide which one its uses was to de-sulfur pig iron, cast steel, and steel.

The containers were put in solid bottom, solid end, steel gondolas for transport.

Mainline Modeler did a great article on these cars a few years back. Again, I'll try to remember when I get home to send everyone a detailed account of these cars.
