8 HOURS LONG — Quiet Overnight Train Sound for Sleep | Sleeper Berth Window

Eight hours of a quiet overnight train ambience, heard from a sleeper carriage: a low rolling sound beneath a soft, steady rail rhythm. No whistles, horns, station announcements, voices, alarms, or sharp wheel squeal. The soundscape is an original design rather than a recording of a real train or route. The subdued sleeper-carriage artwork is an original digital illustration. This is an ambient listening experience, not medical advice or a promise of sleep.
