Under the Shazhong line project, in order to cope with the extension of the East Rail line across the sea, MTR has gradually replaced the current 12 trucks with 9 trucks. All 37 trains are expected to take 1.5 years to complete.
MTR announced earlier that the new signal system and new trains will be put into service on Saturday (12th).
The new signal system will be put into service soon. "Hong Kong 01" received news that during the recent exercise of the new signal system by the MTR, the signal system was suspected of having a "wrong route" accident. , "Wrong line" caused the train to go to the wrong destination.
The news continued that it was further discovered afterwards that after switching to the new signal system, there was a chance of "wrong line" problems passing through other ports.
The MTR will hold a reporter at 6 o'clock in the evening, and it is reported that relevant matters will be announced.
It is understood that the Electrical and Mechanical Services Department urgently called the MTR to report the problem last night (10th). The Electrical and Mechanical Services Department is still holding meetings with the relevant departments to discuss matters.
Whether the new signal system and the new train can run the new train safely as scheduled, or keep variables.
The MTR responded late last night that the new signal system of the East Rail Line is still scheduled to be put into operation tomorrow.
The wave port position may have similar problems
According to sources, during the recent exercise of the new signal system by the MTR, it was suspected that the system had a "wrong route" problem. When the train passed through the port, the train had "entered the wrong route" and failed to enter the correct track section to reach the expected destination.
After the investigation, it was further discovered that under the operation of the new signal system, the train may have similar problems at other ports.
According to the current driving route of the East Rail Line, once the system fails and "takes the wrong path", originally from Sheung Shui to Lo Wu Station or go to the wrong direction to Lok Ma Chau Station; when going northbound in Sha Tin, go to Fo Tan or go to the wrong racecourse station.
EMSD and MTR held an emergency meeting for two consecutive days
According to "Hong Kong 01", the Electrical and Mechanical Services Department urgently called the MTR to understand the incident last night. This morning, the senior officials of the Electrical and Mechanical Services Department are still discussing with relevant departments.
The new signal system and new trains on the East Rail Line will be put into service tomorrow (12th). Whether it will be implemented as scheduled is still unknown. The authorities will make a decision tonight at the latest.
"Hong Kong 01" asked the MTR Corporation about the incident and received a reply last night stating that the signal system involves tens of thousands of electronic system components. The conversion of the new system is by no means easy, and it will take time to run in the initial stage of service.
At the same time, it is pointed out that the new signal system of the East Rail Line is scheduled to be put into operation on Saturday and has entered the final stage of preparations. The final stage of testing will ensure that colleagues are familiar with various situations and improve the system settings to ensure smooth system conversion. Shun.
However, in the reply, the MTR did not mention whether the system has ever encountered a "wrong way" problem.
Zhang Niansheng, vice president of the Hong Kong Branch of the Institute of Railway Signalling Engineers, believes that the problem will have a serious impact. If the forced service is not satisfactory, the new system should be checked again before starting the new system. "It's better to get it back!"
Nine trucks were originally scheduled to be added to driving tomorrow
The East Rail Line update information system project started in the third quarter of 2015. The new signal system supplier is Siemens, which uses communication-based train control technology.
Looking through the documents, the data showed that the new signal system of the East Rail Line was originally scheduled to be replaced in 2019, and it was also announced in mid-April this year that it would be put into service in the middle of the year.
However, at the end of May this year, the East Rail Line tested the new signal system during non-traveling hours, and three accidents occurred, which caused the test run to be suspended for nearly a month. It is now announced that it will be in service tomorrow (12th, Saturday).
Regarding the three accidents that occurred in May, the MTR has repeatedly emphasized that after investigation, it was confirmed that it was caused by human factors or operating procedures and had nothing to do with system safety.
At the same time, it also pointed out that the new signal system and the new train have undergone rigorous and comprehensive testing, and more than 6,000 drills have been conducted to confirm that all operations are smooth and meet the requirements of relevant government departments. Therefore, it is described that everything is ready. In September On the 12th, safe and reliable railway services will be provided to passengers.
Looking at the information, the contract for the new signal system was awarded in December 2012, with a total contract value of 845 million yuan.
