Dead Rails is a Roblox western survival game in which players ride a train across a zombie-infested frontier, gathering supplies and fighting off enemies while trying to reach the end of the line. Because runs can end suddenly, death moments became a natural source of clips for streamers and short-form creators, who lifted the game's death cue for montages, fails and reaction edits. It remains popular because it instantly tells viewers a run is over, without needing any explanation or on-screen text.
