Stationmaster → It is formed from "station" (from Latin "stare", meaning to stand) and "master" (from Old English "maegester", meaning one who has control or authority). The word "stationmaster" refers to a person who has authority or control over a station, typically in a transportation context.
Think of someone who has the authority to oversee a place where things 'stand' or stop ('station') — that's why a stationmaster is in charge of a station.
