Place this clip at the opening of a railway sequence, then follow it with a Metal Pipe Clang for the doors and a Dun Dun Dun for the reveal, keeping the horn as the first signal in the chain.

This is a short, roughly one-and-a-half-second blast from an electric locomotive horn, with a deep, brassy tone that cuts through background noise. It feels powerful and urgent, like a train announcing its arrival, and carries a touch of railway nostalgia that makes it instantly recognisable even without any words.
