oooh, man, toughy right here.
Sometimes un-bagged fertilizer might, some hazardous materials may, like chemicals that might react to water, etc.

I assume you are not talking about metal covers used in coil cars. When I worked out of the PC/Conrail/CSX Selkirk Yard Auto Site in NY, I used to see canvas(or something similar) covered gondolas containing high grade metal, metal containers filled with some kind of high grade ore (so I was told) out of Canada I guess as these were CN gon's. In others what appeared to be machinery.
My copy of "Freight Train Cars" by Schafer and McBride states, "Covered gondolas are used to move moisture-sensitive lading...While regular open-top gons were fine for handling such dense, heavy cargo as scrap metal, crated freight, ceramic piping, brick, cable reels, and rail, covered gons were used to carry similar heavy items that required protection from direct moisture. Newly rolled steel that was to be used in food-product containers or similar applications where it had to be absolutely rust free was an ideal candidate for the covered gondola."

Chemicals that might react to water are more likely to be carried in a ventilated van or tanker than a covered Gondola. Unbagged fertilizer is more likely to be carried in a Pres-flo style wagon.
