The MTR has installed a flood detection system at 26 stations to prepare for the upcoming rain and typhoon season. This initiative comes after Wong Tai Sin Station was flooded during a heavy downpour last September, leading to the partial suspension of the Kwun Tong Line.
According to the MTR's Chief of Airport Segment, Ben Lui, flood sensors have been placed at 42 entrances and exits. When the water reaches these sensors, an alarm is triggered, alerting station staff to check the CCTV and set up flood barriers to cordon off the affected area. The MTR will also make announcements for the public to use alternative exits.
Furthermore, the MTR will suspend all services on above-ground sections, including the light railway and airport express, whenever Typhoon Signal No. 9 or higher is in effect. If trains are still above ground when the second-highest typhoon signal is raised, they will continue to their designated destinations or significant stations, where passengers can find shelter. The MTR will also provide water and food for affected passengers in such circumstances.
Lawmaker Gary Zhang, a former MTR engineer, praised the flood sensors for providing early alerts to staff, allowing them to take proactive measures. However, he expressed concerns about the safety of station staff who must manually set up flood-proof barriers during extreme weather conditions. Zhang suggested that the MTR consider installing automatic flood-proof barriers to minimize risks to staff.
