The Land Transport Authority (LTA) has awarded two contracts for the provision of four key systems – signalling system, platform screen doors (PSD) system, Integrated Supervisory Control System (ISCS) and communications system – for the Cross Island Line (CRL).

2.The first contract, valued at around $450 million, was awarded to Siemens Mobility Pte. Ltd. / Siemens Rail Automation, S.A.U. Consortium (Siemens) and covers the CRL signalling system and PSD system.

3.The scope of the contract includes the design, manufacturing, supply, installation, testing and commissioning of the communication-based train control (CBTC) signalling system as well as the PSD system.

4.Siemens had earlier completed the signalling and PSD systems for the Downtown Line (DTL). They are also implementing the signaling and PSD systems for the Downtown Line 3 Extension (DTLe) and the Jurong Region Line (JRL).

5.The second contract, valued at around $200 million, was awarded to ST Engineering Urban Solutions Ltd. (previously known as ST Engineering Electronics Ltd.)  and covers the ISCS and communications system.

6.This contract includes the design, manufacturing, supply, installation, testing and commissioning of ISCS and communications system. The communications system for CRL comprises various sub-systems such as the communication backbone network, digital trunked radio, video surveillance, public address, telephone, and travel information system.

7.ST Engineering Urban Solutions had previously completed the communications systems for the North-South and East-West Lines, Circle Line and DTL, as well as the ISCS for the Circle Line and DTL. They are also implementing the ISCS and communications systems for JRL, DTLe and Circle Line Stage 6.

8.Offers for the four systems were obtained as an option in the JRL tender to reap economies of scale.  In awarding the contracts to Siemens and ST Engineering Urban Solutions, a range of factors were taken into consideration, including cost-competitiveness, quality of the solutions proposed as well as bidders’ expertise and track record.

About the CRL

9.The Cross Island Line (CRL) is Singapore’s eighth MRT line. It will serve existing and future developments in the eastern, north-eastern and western parts of Singapore, linking major hubs such as Jurong Lake District, Punggol Digital District, and the Changi region. Almost half of the CRL stations will be interchanges with other rail lines, making it easier and more convenient for commuters to travel across the rail network.

10.CRL will be constructed in three phases. Announced in 2019, CRL Phase 1 (CRL1) is 29 kilometres long, and will comprise 12 stations from Aviation Park to Bright Hill^[1]. As of March 2022, all civil contracts for CRL1 had been awarded. Construction works have commenced and are expected to complete by 2030. CRL Phase 2 (CRL2), announced in 2022, is approximately 15 kilometres long and comprises six stations from Turf City to Jurong Lake District. The 7.3-kilometre CRL-Punggol extension (CPe) will comprise four stations from Punggol to Pasir Ris. CRL2 and CPe are expected to be completed in 2032. Engineering studies for CRL Phase 3 are ongoing and more details will be announced after these studies are completed.
