1. On High-Capacity Systems, pre-recorded broadcasts are activated by wireless transmission near the tracks, triggered as the trains arrive at the station. 2. Train operators use pre-recorded and live broadcast in specific areas to provide information to passengers. 3. Train operators use both pre-recorded and direct broadcast to alert passengers in the event of special circumstances.
