CRRC Qingdao Sifang CR151

The CRRC Qingdao Sifang CR151 is a type of electric multiple unit ordered for the Cross Island Line of Singapore's Mass Rapid Transit system. The contract went to CRRC Sifang, a consortium of CRRC Qingdao Sifang and Singapore CRRC Sifang Railway Vehicles Service, and by June 2023 the Land Transport Authority had bought 44 six-car trains, with an option for up to 11 more. The tender closed on 23 September 2022 with four bids. Each car has ten doors, five on each side, and the gangway between cars is 1.6 metres wide against 1.4 metres on other lines. Unlike most Singapore lines, the trains draw power from a 1,500 volt direct current overhead conductor rail, and some will carry an automated track inspection system. A set is two driving trailers and four motor cars, and two sets can be coupled into an eight-car train. The first train was delivered in May 2026, with the rest due before the line opens in 2030.
