The CRRC Qingdao Sifang CR151 is a type of electric multiple unit to be built for the Cross Island Line of Singapore's Mass Rapid Transit (MRT) system. The contract was awarded to CRRC Sifang, a consortium of CRRC Qingdao Sifang Co and Singapore CRRC Sifang Railway Vehicles Service, and as of June 2023 the Land Transport Authority (LTA) has purchased 44 six-car trains. They will be delivered from 2027, before the opening of the line's first phase in 2030.
The tender for trains under the contract CR151 was closed on 23 September 2022 with four bids. The LTA has shortlisted all of them and the results has been released. The contract includes the option of purchasing up to 11 more trains. The tender results were published on 14 June 2023 on the Singapore government's GeBIZ platform:[2]

Each train car will have 10 doors per car (5 on each side), condition monitoring and diagnostic systems for early detection of potential equipment faults. Some trains will also be equipped with an Automated Track Inspection system to monitor the condition of the running rail and OCR in real time. Between train cars, the gangway width is at .[3] Unlike most of the MRT lines in Singapore, these trains will draw power from a 1,500 V DC overhead conductor rail.[4]
The coupling configuration of a CR151 in revenue service is DT–Mp–Mi+Mi–Mp–DT.
