They're used to align the pf in the cab. There's one on each side so when you put the pf down it centres on them. I've only ever seen them on modern Sterns.
Thanks ronsplooter - that makes sense. Only one of them was in the way of the side mirrors, and it must be about half an inch higher than the other. Strange.
