Bob Schliecher had an article maybe a decade ago on the side dump cars,I've never seen any photographic evidence that Hart Selective ballast

mfrs. (which I assume are the cars you're talking about) ever went off
line, regardless of who owned them. So I'm as skeptical as you are.
There's evidence that some RRs (e.g., the UP) sometimes hauled coal in
them, but with the cars being costly to build and maintain and intended
primarily for ballast service, I can't imagine any RR willingly allowing
them to go off line in interchange.
