Train horns have been used as warning signals on locomotives since the early days of rail travel, designed to be heard over long distances at crossings and stations. Recordings of the blast circulate widely on soundboards in Russian and English under names like gudok poezda, where short isolated clips are shared for editing. Creators reuse this version because it is clean, loud and self contained, making it easy to drop into memes, simulators, animations and prank videos without needing a full railway recording or background noise.
