Two serious accidents happened to the MTR in just one month. The train at Tseung Kwan O Station had a "mechanical failure" early yesterday (5th). The hook connecting the two trains was displaced. four hours.
Zhang Xinyu, vice-chairman of the Subcommittee on Railway Matters of the Legislative Council, said in Hong Kong and Taiwan's "Millennium" today (6th) that "slipping the card" is the most dangerous type of train failure. Fortunately, the safety protection device worked, so there was no damage to the train It is also a "good luck" for the second danger, and there are no casualties.
He believes that MTR accidents have happened one after another, and the maintenance system and manpower arrangements should be comprehensively reviewed, rather than remedying the situation. If there are still doubts after the detailed investigation results are released, the Hong Kong government should consider stepping in or appointing a third party to conduct an independent investigation.
Sai Kung District Councilor Fang Guoshan said that the accident paralyzed the railway traffic in the Tseung Kwan O District and caused chaos. The two accidents have historically occurred in Hong Kong. It is inferred that the air hose of the pneumatic device involved in the truck was caused by "air leakage", but the exact cause will be announced after the MTR investigates.

Zhang Xinyu pointed out that according to the photos provided by the passengers and the Fire Department, it is believed that the connection between the train and the train is loose. It is the most dangerous. "It is impossible to split into two. Fortunately, we entered the tight station at that time and slowed down the speed." The alarm system was activated, and the safety protection device was activated, and then the brakes were applied. "It is lucky that there were no casualties."
He said that there are mechanical, electrical and pneumatic connections between the trucks, but there is not enough information at this stage, and it is difficult to judge the cause of the loosening. However, he is worried that the MTR's successive accidents in key railway systems in the short term may not be caused by a single technical factor. There are even systemic maintenance risks, and I believe that MTR should comprehensively review the maintenance system and manpower arrangements.
Now every time an accident occurs, the MTR is trying to fix the situation. "Every time it is like putting out a fire, but the more we do it, the less routine preventive maintenance will be done. As a result, the risk of failure will increase again, creating a vicious circle." He believes , after MTR announces the investigation results, if there are still unsolved doubts, the Hong Kong government should consider intervening or appointing a third party to conduct an independent investigation.

Sai Kung District Councilor Fong Kwok-shan said that there was chaos after yesterday's accident, and "Tseung Kwan O residents are hard-fed," expressing their disappointment with the MTR.
She also pointed out that many trains lost their lights at that time, and there were babies, pregnant women and the elderly on board, but the passengers were evacuated after being trapped on the train for half an hour.
In addition, more than an hour after the accident, the shuttle bus did not see the relevant instructions, and it was believed that the MTR needed to be improved.
Fang Guoshan also said that although the MTR stated afterwards that it would comprehensively review the existing asset management and maintenance system, she believed that the Hong Kong government, as the largest shareholder, should review the backup plan for the service paralysis after the MTR accident, and the population of the Tseung Kwan O area is expected to increase in 2030. Increased to 700,000 people, "The backbone of the railway must be looped so that it will not be paralyzed again."
Zhang Niansheng, chairman of the Hong Kong Railway Transportation Professionals Association, pointed out that the connection between the two train cars involves three sets of systems, including mechanical, electrical and pneumatic systems. Pneumatics fail.
He estimated that it may be caused by the aging of the air pipe, or the "leakage" caused by maintenance, or it may be due to the problem of the material of the air pipe, but the cause needs to be found out after the MTR investigation results.
He also pointed out that the train that caused the accident this time is a Korean-made train commonly known as "K-train", which is used in different places all over the world. However, during his more than 30 years of working in the railway industry, he only saw two accidents on the same Korean-made train. Both times the lucky lottery happened in Hong Kong.” The last time was in 1993 when the train on the Tsuen Wan Line was “off the card” when it was heading to Tai Wo Hau Station, but the situation at that time was slightly different from this time.
Suspension of the Tseung Kwan O Line | The Electrical and Mechanical Services Department requires the MTR to submit a preliminary report within 3 days to complete the investigation of the decoupling of the Tseung Kwan O Line trains within two months｜Zhang Xinyu: One of the most serious accidents Members urged to increase the decoupling of the trains connected to the Tseung Kwan O Line｜Lin Shixiong ordered the MTR to thoroughly investigate the cause of the condolences Two passengers sent to the hospital were surrounded by the Tseung Kwan O Police Station. The man with colon disease admitted to the riot. The officer considered his health and imprisoned him. In December, the train on the Tseung Kwan O Line was decoupled｜The service was blocked for about 4 hours. It is expected that the MTR will be fined 5 million according to the mechanism. The 7-card connection station is faulty and the MTR stops running for 4 hours to avoid talking about cards.
