Red Dead Redemption 2, released by Rockstar Games in 2018, is an open-world Western set in a fictionalised American frontier, where trains regularly cross the map and their whistles are part of the ambient soundscape. Clips of that whistle have circulated on soundboards and in fan edits ever since, because the sound is instantly recognisable even to people who have not played the game. It remains popular for Western edits, roleplay videos and travel content, where a single whistle can establish setting, distance and mood without any explanation.
