MTR says that following the resumption of dynamic train tests for the East Rail Line’s new signalling system at the end of May, the comprehensive safety review of the signalling system for the Tuen Ma Line has also been completed and confirmed that the system meets the safety requirements for dynamic train tests.

MTR will gradually resume the dynamic train tests on the Ma On Shan Line, West Rail Line and the newly built section of the Tuen Ma Line starting from June 10 during non-traffic hours.

Under the Shatin to Central Link project, the Tai Wai to Hung Hom Section will connect with the existing Ma On Shan Line and West Rail Line to form the Tuen Ma Line. The signalling system for the Tuen Ma Line is an extension of the existing signalling systems used for the Ma On Shan Line and West Rail Line.

While the system design is different from that of the new signalling system for the Tsuen Wan Line, testing of the Tuen Ma Line signalling system was temporarily suspended since the Tsuen Wan Line incident in March as a prudent measure.

Thales and Alstom are installing Thales’ Seltrac CBTC system across seven metro lines in Hong Kong under a €330m contract awarded in 2015. The suppliers are replacing existing Automatic Train Supervision (ATS), interlocking and Automatic Train Control technology in the control centre, onboard trains and at stations.
