MTR Causeway Bay Station yesterday (3rd) accident occurred in the door of a train, which once blocked the Hong Kong Island Line train for nearly three hours.
MTR train operation and local railway manager Huang Kunwei pointed out that after investigation after the train was received last night, the reason for the lock was due to the displacement of the billboard component, which caused the door to fall off when it touched the door. On Thursday, the contractor replaced the advertisement.
Zhang Niansheng, chairman of the Association of Railway Transport Professionals, pointed out that it is currently difficult to judge whether the accident involved fatigue or rusting of the billboard components. However, because the billboards need to be replaced regularly, it is believed that the cause may involve human negligence, or because the engineers did not perform the replacement process. There are locking components.
The service of the MTR Island Line between Wan Chai and Tai Koo Station was temporarily suspended in the evening due to the loss of the car door.
According to the delay certificate issued by the MTR, the service of the Island Line will be affected from 5:54 pm to 8:46 pm, that is, a delay of 2 hours and 52 minutes.
The engineer estimated that the accident was caused by the negligence of the contractor to loosen the billboard components
Zhang Niansheng, chairman of the Association of Railway Transport Professionals, said on a radio program this morning (3rd) that there are two possible causes of the accident, including problems with the doors themselves and problems with the equipment beside the tracks.
However, he believes that the MTR’s preliminary report last night has reasonably explained the cause of the accident. He also believes that the MTR has done a good job in safety management and maintenance of trains. Therefore, "don’t believe that there is a problem with the doors themselves."
He pointed out that it is currently difficult to judge whether the accident involved fatigue or rusting of the billboard components, but because the billboards need to be replaced regularly, "it will definitely be dismantled and replaced. I know that this process is the responsibility of the outsourced advertising contractor. Will it be incomplete and safe to meet the requirements of the MTR?" He also believes that the cause may involve human negligence.
He added that it may be because the engineering staff did not lock the components during the replacement process. He described that "it may be that after a period of driving, the station will vibrate, shake loose, and fall down." There is a shock absorber system on the platform. The public may not be able to feel the vibration, "but (when driving) the vibration of the entire station and the tunnel is not very detailed."
It is recommended to install a billboard monitoring system on the track
Zhang Niansheng also explained that the door source uses a hook-type design. The frame on the top of the door has a crossbar to control the grinding when opening and closing the door. "It's like a shower curtain or curtain hanging up."
He believes that the design of car doors is in use all over the world, and the doors are systematically monitored to see if they are closed properly. He believes that the train design is safe, but he also recommends that passengers avoid getting close to the doors as much as possible.
He said that there is generally a distance of 100 to 150 millimeters between the car door and the billboard. It is recommended that the MTR can set up a monitoring system on the track for the safety of the billboard. If the billboard exceeds the distance, an immediate warning will be issued.
MTR New Power Chairman Chen Kaihui said that this is the first time I have heard of a similar accident. After learning of the accident, the immediate reaction was "Is there a mistake, something happened, what will happen?" (data picture)

MTR New Power Chairman Chen Kaihui said that this is the first time I have heard of a similar accident. After learning of the accident, the immediate response was "Is there a mistake, something happened, what will happen?" He also pointed out that the accident happened in the afternoon. During peak hours, the train has been running for about 10 o'clock, and I don’t understand why the billboards are "no la la la bombs." He also described the accidental people as lucky, "the impact force is so big, so it’s so slamming, it’s hard to get close." This is a good event."
He explained that the billboard is composed of a large piece of glass, which can be flipped upward to replace the advertisement and set a lock. The advertisement is replaced when the car is retracted. It is estimated that the cause of the accident was that the billboard was not properly locked and airflow was generated when the train passed by. It has nothing to do with the car door itself.
He believes that the MTR needs to investigate the cause of the accident, whether the contractor's process is involved, and strengthen inspections.
He also revealed that MTR currently outsources a lot of station work to contractors, mainly because some of the work is not railway-specific, such as cleaning, replacement of advertisements, etc., so it needs to outsource special contractors.
The reason for the MTR lock-up is the removal of the billboard components is related to the train
The MTR train operation and local railway manager Huang Kunwei said on the program that after the investigation after the train was received last night, the reason for the lock was that the billboard component was shifted and the door fell off when the door was touched. The train service was ruled out this morning. The same remains normal.
He emphasized that the MTR conducts strict inspections every day before leaving the train to ensure that the train can operate safely. Every night after the train is received, the train equipment will be subject to rigorous maintenance procedures, so passengers can rest assured.
He pointed out that in the future, investigations will continue, including reviewing the billboard design, operating procedures, the current state of the billboard involved, and the process of changing the billboard. "We will definitely investigate in detail to see where the shift occurred."
In addition to dismantling the related components that are suspected of causing the accident, a comprehensive inspection of the different types of light boxes across the entire line has also been arranged and will be reported to relevant government departments as soon as possible.
The light box involved was replaced by the contractor last Thursday.
Mr. Wu Wei-hung, the manager of the MTR train service project, added that the large billboards involved can be used to place light box advertisements or put large sticker advertisements. Together with the billboards involved, there are a total of eight billboards of the same type on the entire line. Stations.
The related displaced billboard components are usually used when replacing advertisements, and are located under the billboard.
Huang Kunwei pointed out that the advertising light box involved was replaced by a contractor last Thursday.
Regarding accident response, Huang Kunwei pointed out that the staff had reported the accident to the train control center immediately, and arranged the assistance of station staff to arrange for passengers to leave the carriages in an orderly manner. The MTR also arranged 90 shuttle buses; speak bluntly and understand the busyness. Time will affect passengers. "A little bit will cause inconvenience to passengers. I really have to speak up."
