This article is about the Cross Island Line (CRL) trains. Click here for Alstom Movia R151 trains on the NSEWL.

The CRRC Sifang CR151 train is an electric multiple unit (EMU) train which will operate on the upcoming Cross Island Line (CRL). Projected to enter service in 2030, these are the CRL’s first generation of rolling stock. Trains will be built in China and are expected to be delivered progressively from 2027.

Forty-four (44) trains were procured under Contract CR151, with each train formed of six cars. As the CRL is designed and built to accommodate 8-car trains, these trains should be able to be extended for 8 car operations if required.

Trains will also draw power from an overhead conductor rail (OCR) system as referenced from Contract CR159 at 1500V DC.

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 1.6m.


An LTA-issued tender for these trains, Contract CR151 – Trains for Cross Island Line, was published on the government procurement website GeBIZ on 18 March 2022 and closed on 23 September 2022.

On 14 June 2023, Contract CR151 was awarded to the consortium of CRRC Qingdao Sifang Co., Ltd and Singapore CRRC Sifang Railway Vehicles Service Pte. Ltd (CRRC Sifang) at a contract value of $589 million.
