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 1.6m.

Tender

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.

Four companies responded to the tender, namely:

• Alstom Transport (S) Pte Ltd
• Construcciones Y Auxiliar De Ferrocarriles, S.A.
• CRRC Qingdao Sifang Co., Ltd.
  (tendered as a consortium)
• Hyundai Rotem Company

Tender Award

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.

This includes the supply of 44 six-car trains, as well as options to procure up to 11 additional trains and the provision of Long Term Service Support.

Train Formation

A six-car trainset is formed of two three-car sets permanently coupled together. Each set comprises one driving trailer (DT) and two motor cars (Mi and Mp). As such, the running configuration of a CR151 trainset is DT–Mp–Mi–Mi–Mp–DT.

Signalling

On April 2o23, Siemens Mobility was awarded an LTA contract to provide a CBTC signaling system and full-height platform screen doors for the Cross Island Line.

According to Siemens, it will provide the Trainguard CBTC solution, modern interlocking Westrace MKII and Automatic Train Supervision (ATS) Rail9k to support the maximum grade of automation, GoA 4, and allow fully unattended train operation along around 50 kilometres of track and 21 stations of CRL1, CRL2 and Punggol Extension.
