A friend whose grandfather worked at ?Waverley Depot in Sydney said that this is a job he did.

South Melbourne depot around 1990 got a batch of 'Ferrodo' brake shoes with a layer of carborundum glued to the face of the shoes.

The experiment can't have been a success because no more were seen.

Nevertheless those composition brake should would very slowly grind away minor flats, but not during just one shift.
