Development

In conjunction with the upgrade of the existing signalling system from Advanced SelTrac CBTC to Système d'aide à la conduite, à l'exploitation et à la maintenance (SACEM), MTR Corporation originally planned for 93 8-car trainsets to be ordered. This arrangement was made as a replacement to the existing M-Trains, currently the oldest trains on the network, having been in operation since 1979.[4] The order was subsequently increased to 93 trainsets at HK$6.05 billion (US$779 million) on grounds that it provided "better value for money".[3][5] The trains will operate on the Kwun Tong line, Tsuen Wan line, Island line and Tseung Kwan O line and all trainsets are expected to be fully delivered by 2023.[3]

However, the signalling system replacement has been severely delayed due to a crash on the Tsuen Wan line in 2019 during non-traffic hours.[6] While a small number of these trains have been delivered to Hong Kong since 2018, these trains have been parked at various depots on the MTR's Urban Lines as well as the Siu Ho Wan depot, except for a few rare test runs. As the contractor for the SelTrac system has still failed to deliver a proper software fix for the system, MTR announced in March 2022 that all 93 trainsets would install SACEM initially and then switch to SelTrac when it is possible to do so,[7] with the first train entering service before the end of 2022. This ensures that the oldest M-trains can be retired on time.

Design

In accordance with MTR press release, these new set of trains will be featured with improved lighting system, new dynamic route maps, double branched handrails and soft material for the straphangers.[8] The livery is similar to all new MTR trains since 2016, namely the S-Train, TML C-Train and R-Train which run on the South Island line, Tuen Ma line and East Rail line respectively.

All train doors and coupler systems will be provided by Faiveley Transport. Coupler systems are automatic and semi-permanent couplers.[9]
