Well, based on the classic 1931 Erector set Hudson loco model, I'm guessing it's either something called a steam dome or sand box. Looks more like the steam dome from the attached Erector Hudson parts breakdown. Definitely wouldn't want to drop it on your toes.

Probably a pot full of molten lead .
