Hong Kong’s MTR Corp to upgrade Tung Chung line signalling system on Sunday night

Hong Kong’s MTR Corporation will carry out overnight signalling upgrade works on Sunday as part of preparations for the partial opening of the Tung Chung line extension later this year.Representatives from the city’s sole rail operator also said on Wednesday that the HK$19.5 billion (US$2.5 billion) project remained unaffected by a counterfeit brick scandal and the full extension was still on track to open in 2029.Upgrades to the existing system will take place in the early hours of Sunday, said Tim Leung Chi-tim, the MTR’s general manager for railway and system integration, at a press briefing.Work involves upgrading the automatic train supervision system (ATSS), which is responsible for real-time central monitoring and train dispatching, to support the two new stations, Tung Chung East and Tung Chung West, he said.Leung added that the upgrade was part of preparations to integrate the new track sections into the wider network, but pledged that the work would be completed before the first train in the morning, ensuring normal services on the Tung Chung line and Airport Express.“The upgrade will enable the new track section to be similarly integrated into the existing railway network with centralised operational monitoring and train regulation,” he said.
