East Japan Railway Company (JR East) has introduced an escalator congestion emergency stop system on four single-person escalators located inside the Shinkansen ticket gates at Tokyo Station, starting March 5.
If a passenger falls near the exit of a single-person escalator, there is a risk that following passengers will be pushed forward, leading to secondary accidents. To address this, JR East has put in place a system that automatically detects congestion near the exit and performs an emergency stop. When a three-dimensional sensor installed near the exit detects congestion, the escalator issues audio and light alerts to warn following passengers and then performs an emergency stop.
JR East is also considering deploying the system at other locations where the risk of congestion occurring is high. Initiatives related to the escalator congestion emergency stop system have received the Chairman’s Award of the Japan Association of Rolling Stock and Machinery for Railways at the 2025 National “Rolling Stock and Machinery” Research Presentation Meeting, organized by the Japan Association of Rolling Stock and Machinery for Railways.
