My educational journey today: “Hm, I suppose that’s probably a stopcock or something similar, so it was something to do with regulating water level for the boiler.” Searches for steam locomotive diagrams. “Huh, turns out that there were actually 10 parts of a steam locomotive that had the word ‘cock’ as part of their name.” TIL

this is exactly why I’ve become a Marxist

joke’s on you, i’m not an engineman so i can drain all the cocks i want
