Huh? What does that even mean? The train already announces the train station name, so why does it need a specific button for the specific jingle? Does not sound right.
Its not an automated operation, the train jingles play a few seconds before the conductor closes the door. Its played at different times depending on congestion on the train platform.
Right, but the train knows where it is. The screen shows it. Why is the jingle not connected to the same system as the train's screens? Everything is on the screen, even the doors closing animation. No excuse, really.
