A train derailment accident occurred on Sunday morning (13) at Yau Ma Tei MTR station, causing multiple doors to fall. After emergency repairs, train services on the Tsuen Wan Line returned to normal yesterday morning. Li Jiarun, director of railway operations of the MTR, revealed yesterday that a component of the metal guardrail on the track side of the tunnel was initially believed to have moved and collided with the train, causing the train to be diverted. Transport and Logistics Secretary Lam Sai-hung has asked MTR to submit a preliminary investigation report tomorrow (16).
Lee Ka-run revealed on an RTHK program yesterday that the crash was initially believed to have been caused by a moving metal guardrail component near the tunnel track, which collided with the train and caused it to derail. The MTR will examine the use, maintenance, wear and design of relevant components to see if human errors are involved, while external experts will conduct thorough investigations to confirm the actual cause. As to whether component maintenance should be undertaken by MTR itself or outsourced, Li Jiayun said that maintenance involves various provisions and guidelines, and will review the relevant component maintenance procedures.
Zhang Xinyu: It is necessary to review the maintenance and repair of equipment
Zhang Xinyu, vice chairman of the Legislative Council Railway Issues Subcommittee, estimated that the maintenance of the protective cover of the exhauster in the moved track was insufficient, which caused the protective cover to loosen or not be tightened after the track works, which led to the accident. Zhang Xinyu believes that, coupled with the incident of the door being knocked down at Causeway Bay station in December last year, it shows that the MTR has much room for improvement in the maintenance of platform equipment, and there is a need to review the maintenance provisions .
In addition to the cause of the accident, the public is concerned about the passenger evacuation arrangement after the accident, including 600 people were evacuated through the Yau Ma Tei platform, and about 150 passengers were dropped off through the emergency escape route in the back of the train. They walked from Yau Ma Tei Station to Mong Kok Station along the tunnel tracks in the dark. The Tang Line train to Huangpu runs in parallel. Zhang Xinyu pointed out that according to the code, the relevant position of maintenance personnel should not be at the same time as the train is moving. The passengers have not received railway training and are not familiar with the environment.
Huang Kunwei, head of MTR railway operations and head of local railways, was asked on the Hong Kong TV show whether the staff provided any assistance during the evacuation of passengers along the platforms and replied that the passengers opened the ramp emergency and walked along the Tsuen Wan Line to Mong Kok Station. The MTR learned Subsequently, staff were arranged to help passengers get back to the platform at Mong Kok Station, and staff were also sent to inspect the tunnel to make sure no one stopped. As to whether the passenger asked to open the escape passage at the rear of the train, or whether the train captain instructed him, the MTR said it would investigate further.
Transport and Logistics Secretary Lam Sai-hung responded to the accident yesterday afternoon meeting with the media, believing that MTR completed the restoration yesterday morning and downplayed the impact, but asked MTR to submit a preliminary report investigation report tomorrow, including the preliminary cause of the accident, follow-up work and evacuation methods, etc., and the entire investigation must be completed within two months; the electrical and mechanical services department has instructed MTR in writing to conduct a comprehensive inspection of the railway network systems and facilities, and carries out regular inspections and maintenance to ensure reliability and safety.
