Please. "paper" wheels shunt track circuits just fine, since they have steel tires, cast iron hubs, and a pair of steel plates that connect those parts together. The pressed paper was just a filler, which helped deaden the squealing sound that wheels made on curves.
I'd have to guess that one reason that paper centred wheels fell out of favour is that a car fitted with them would not operate track circuits. Also the paper centre must have gotten fouled with journal box oil over time. Some heat from the brakeshoes, and you'd have a flaming wheel?
How did paper wheels enter into this discussion?
