A rare incident of "car door slamming" occurred on a train on the MTR Island Line yesterday (2nd) evening.

According to the MTR, after investigation after the train was received last night, the main cause of the locked accident was the displacement of the billboard components, which caused the door to fall off when it touched the car door, and it was ruled out that it was related to the train.


However, the British-made Jiamu Train (commonly known as M-Train) has been in operation for nearly 40 years. It was refurbished more than 20 years ago. The MTR also improved its doors about 6 years ago.

The Democratic Party quoted expert opinions and questioned that simply loose billboard components would not necessarily cause the car doors to fall off, and urged the MTR to set up a special investigation team as soon as possible to investigate the real cause of the accident.


Tian Beichen, a member of the Legislative Council and former chairman of the KCRC, pointed out that the British-made train involved has been in service for nearly 40 years. The accident does not rule out the metal fatigue of the train. It requires the authorities to fully inspect the safety of the doors of the same-age older trains in the fleet.

The DAB Chen Hengpin also believes that the MTR should expand the scope of investigation and at the same time investigate the safety of train doors.

In the early years of the MTR, the British-made Jiamu train, the capital city of England, originally had a guiding track design at the bottom of the door. When the train opened and closed the door, the door would move along the guiding track.

Looking through the information, MTR once pointed out that due to the design of the door track, the door could not be closed smoothly due to coins and other foreign objects. Therefore, the doors of all imperial trains were improved around 2015 and the doors were changed to the current new ones. Hook design, the door has a cross bar on the top of the door frame to control the switch.

The Democratic Party urges the establishment of a team to investigate whether the light box parts are indeed the main cause of the incident

According to the MTR, after investigation after the train was received last night, the main cause of the locked accident was the displacement of the billboard components, which caused the door to fall off when it touched the car door, and it was ruled out that it was related to the train.

However, some experts believe that the train has a system to fix and lock the doors. Under normal circumstances, it is not easy to loosen the doors due to collisions inside or outside the car. The loosening of the billboard components does not necessarily cause the doors to fall off.

The Democratic Party’s Transport Policy Spokesperson Han Junxian pointed out that the MTR should comprehensively inspect the daily maintenance of trains and inspect the doors of the same type of trains to protect the safety of passengers. He also urged the MTR to set up a special investigation team to investigate the accident as soon as possible, including Whether the light box parts are indeed the main cause of this incident, and review the routine maintenance procedures, to give the public a comprehensive explanation.

MTR train train engineer with nearly 40 years of age: it is not easy to replace a new train

In recent years, the MTR has replaced the signal systems of many railway lines, and plans to phase out the current British trains and switch to new trains after the new system is put into service.

However, in March last year, when the MTR was testing the new signal system on the Tsuen Wan Line, two non-passenger trains collided and severely damaged due to signal system problems, which delayed the replacement of the signal system.

Faced with the problem of aging trains, Zhang Zidong, former chairman of the Control, Automation and Instrumentation Division of the Hong Kong Institution of Engineers, pointed out that it is not feasible to replace the train first and then replace the system.

It is impossible for the MTR to continue to use the old system for new trains. In the future, the signal system will be updated for new trains, which will increase the work with half the effort.

However, it is not easy to replace the new system. Zhang Zidun explained that it takes a long time to install and test the new system, but it can only be done after the vehicle is put in. Do a round of testing" to ensure that the train is operating normally before it can start operation the next day.

He pointed out that the process of converting the system is time-consuming, and the actual test time is less than four hours. If there is a slight difference in the test period, it may even affect the operation of the next day.

Zhang Zidun: Whether the accident is related to the age of the car still needs to be investigated

Zhang Zidong pointed out that the life of a general train is more than 30 years, but it depends on its design, the accumulated time of running, and the MTR's maintenance efforts.

He pointed out that the MTR regularly repairs and protects trains. If sufficient maintenance is done, the service life of trains can also be improved.

As for whether this incident is related to the age of the train, he believes that the MTR investigation report is required before the scheduled round can be set.

Chen Hengpin: The scope of investigation should be expanded to ensure the safety of train doors

The DAB Chen Hengpin believes that there has not yet been a complete investigation report on this incident, and that the main cause of the accident cannot be jumped on.

However, he pointed out that, after all, the accident caused the car door to fly off, and many citizens often approach the car door. Therefore, in addition to the billboard, the MTR investigation should also expand the scope of the investigation to ensure the safety of the train door and regain the confidence of the public. "Just in case you miss your eyes, the passengers will be relieved by one more glance."

Tian Beichen has already run for direct elections in the Northwest New Territories. His opponents in the same district include Zhou Haoding and Huang Junlang.

Chen Hengpin is one of the candidates for the Southwest New Territories in the Legislative Council Geographical Constituency. In the same district, there are Chen Yingxin of the Federation of Trade Unions and Liu Cheuk Yu of the independent democrats.
