SINGAPORE’s Land Transport Authority (LTA) has awarded systems contracts to Siemens Mobility and ST Engineering Urban Solutions for the Cross Island Line (CRL) which at 50km will be Singapore’s longest fully integrated line when completed in 2032.
LTA has awarded Siemens Mobility a $S 450m ($US 338m) contract to provide CBTC and full-height platform screen doors (PSD) for the CRL’s Phases 1 and 2 and its Punggol Extension. The signalling system will incorporate Siemens Mobility’s Trainguard CBTC solution, modern interlocking Westrace MKII and ATS Rail9k to support automation at GoA 4 to allow fully unattended operation along the full line and 21 stations of the CRL and its extension.
The contract covers design, manufacture, installation and testing of the systems.
Trainguard CBTC is already used on the Downtown Line (DTL) and Jurong Region Line (JRL).
The $S 200m systems contract awarded by LTA to ST Engineering Urban Solutions is for the provision of an Integrated Supervisory Control System (ISCS) and communications system for the CRL. This will support various sub-systems for the CRL and branch, including the communication backbone network, video surveillance, public address and passenger information systems. The scope of the contract involves the design, manufacturing, supply, installation, testing and commissioning of these systems.
ST Engineering Urban Solutions has previously completed the communications system for Singapore’s North-South Line (NSL), East-West Line (EWL), the Circle Line (CCL) and the DTL, as well as supplying ISCS for the CCL and DTL. It is currently in the process of deploying both systems on the Downtown Line East Coast extension (DTLe) and JRL.
“The ISCS will enable real-time, centralised monitoring and control of electrical and mechanical subsystems along the rail network of around 50km,” says ST Engineering Urban Solutions. “The communications system will manage and connect various systems in the trains and stations, utilising the latest networking technologies to enable efficient system operations and maintenance.”
The CRL is under construction in three phases. Construction of the 29km Phase 1, from Aviation Park to Bright Hill began in January year and is due to open in 2030. Construction of the 15km Phase 2, from Turf City to Jurong Lake District, is scheduled to begin in the first half of this year, as is construction of the third phase, the 7.3km fully underground CRL Puggol Extension, from Pasir Ris to Punggol, which is due to open in 2032.
