SMRT completes inspection of tunnel doors after metal layer fell on track in 2025 incident

{"

Investigation Details":"The incident occurred on September 10, 2025, when a metal layer detached from a tunnel door between Expo and Changi Airport stations on the East-West Line and fell onto the left side of the rail track.","

Door Issues":"The investigation found that the door was open when the metal layer detached, and either the strike plate or the lockset of the affected door was loose. The metal cladding was not properly secured with mechanical fasteners or welding.","

Wind Load Requirements":"The bureau determined that SMRT was unaware of the wind load requirements for the doors, which were set by the Land Transport Authority (LTA). The affected door was replaced in 2016, but SMRT was unaware of the wind load requirements.","

Future Actions":"SMRT has improved defect recording and inspection processes post-incident and is exploring better detection of thin objects on tracks to enhance safety. SMRT is also working with LTA to carry out renewal works for these doors, particularly those on the older North-South, East-West, and Circle Lines."}
