Place this clip at the end of a platform scene, just before a cut to the moving train. Put a Bell Ding Sound Effect Button moment right before it as a station cue, then let this clip carry the transition into your next shot without any other effects layered over it.
About this sound
This is a nine-second recording of a Sydney Trains T set carriage as its doors close, with the warning chime and the solid thud of the doors meeting. It feels instantly familiar and a little urgent, like the last moment on the platform before departure. It comes from Sydney's Tangara T set suburban trains.
