Place this horn at the arrival beat of a train edit, after a station ambience bed fades down. Put a bell ding just before it to build a platform announcement sequence, then follow with crowd or passing train sounds to close the scene.

This clip is the horn of a JR E353 series train, a bright dual tone blast lasting about four seconds. It feels urgent and satisfying, like a clear departure signal cutting through station noise. The recording is identified as a Narita Express horn from this series.
