This clip is a steady run of metallic railroad crossing bells, ringing in a regular warning pattern for about twelve seconds. The bright, insistent chimes create a tense, alert feeling, like standing beside the tracks as a train approaches. It works as a clear danger signal, sharp enough to cut through a scene and put listeners on edge instantly.
