Last update date: 2020-06-02 19:40During the test of the new signal system on the Tsuen Wan Line in the early hours of March 18 last year, the MTR caused two trains from Central to Admiralty Station to collide, and afterwards suspended the field test of all signal system updates.
MTR Corporation submitted a document to the Railway Subcommittee today (2nd) to explain the latest progress. It is estimated that the entire Tsuen Wan Line signal system replacement project is expected to take three years to complete in 2023, which is four years behind the original plan for 2019. .

Since the train collision accident on March 18 last year, MTR had initially estimated that it would take no less than a year and a half (that is, until 2021) to complete the entire software inspection and correction. After repeated inspections, MTR and contractors The certification of the consultants hired by the vendors and the approval of the EMSD will only consider resuming the step-by-step field driving test, which will take an additional year and a half to complete. Therefore, the replacement of the entire signal system of the Tsuen Wan Line is expected to take three years to 2023 It was only completed in 2014, four years behind the original plan for 2019.

According to the current estimates of the MTR, the new signal system of the Hong Kong Island Line needs to be put into service within about 18 months (about 2024/25) after the new signal system of the Tsuen Wan Line is put into service; the Kwun Tong Line and Tseung Kwan O Line systems are put into operation on the Hong Kong Island Line system The service has been put into service successively within about 24 months (about 2026/27 years).
The Tung Chung Line, Disney Line and Airport Express Line, which were originally expected to complete the replacement of the new signal system in 2026, were re-planned to cooperate with the Tung Chung Line extension project. Replace it after completion.
