The MTR Urban Lines Vision Train (Chinese: 港鐵市區綫願景列車; also named MTR CRRC Qingdao Sifang EMU, also known as Q-Train) is a new rolling stock ordered by MTR Hong Kong in July 2015.^[3]

Development[]

In conjunction with the upgrade of the existing block signalling system to modern communications-based train control (CBTC) technology, MTR Corporation originally planned for 78 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 1978.^[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]

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.^[6]

All train doors and coupler systems will be provided by Faiveley Transport. Coupler systems are automatic and semi-permanent couplers.^[7]
