Audio pack

Real Sydney Trains recordings are copyright and are not included. If you have your own recordings (announcements, the door-closing sequence, chimes), load them here: files are named by the clip they replace (see docs/audio-pack.md, e.g. doors-closing-sequence.mp3, next-stop.mp3, station-hornsby.mp3). They stay in this browser only.
