Hitachi Rail Wins Signalling Contract for Singapore MRT Stations

Hitachi Rail has been awarded a signalling contract for the construction of the NS3A and NS6 Mass Rapid Transit (MRT) stations on Singapore's North-South Line (NSL). The project will be executed by the company's Singapore-based team, which will leverage its expertise in system integration, testing, and commissioning to incorporate the new infrastructure smoothly. The integration will utilize Hitachi Rail's SELTRAC™ Communications-Based Train Control (CBTC) technology, a globally proven signalling solution already deployed on major metro networks in cities such as New York, London, Hong Kong, and Singapore.

The contract covers the integration of NS3A, a new infill station, and NS6, a future interchange connecting with the Downtown Line 2 extension, into the existing active rail system. Once completed, the NS6 station will enhance overall network flexibility and support future expansions. Alfredo Drago, Head of APAC Region SRS at Hitachi Rail, emphasized the team's focus on minimizing operational disruptions. He noted that utilizing the proven SELTRAC™ CBTC technology alongside extensive local delivery experience ensures a seamless integration while maintaining the high levels of reliability that passengers expect every day.

This award signifies another milestone in Hitachi Rail's long-standing partnership with Singapore's Land Transport Authority (LTA). With a strong track record in rail modernization programs, system upgrades, and signalling integration, Hitachi Rail remains dedicated to providing reliable and resilient railway operations that support the continued expansion and development of Singapore's urban transport network.

Additional Context
This section provides technological and market background not explicitly detailed in the original release.

The construction of "infill" stations like NS3A (Brickland) and NS6 (Sungei Kadut) on an active, heavily utilized rail corridor presents immense engineering and logistical challenges. Signalling systems must be precisely recalibrated to account for the new stopping points without causing systemic delays across the network. Singapore’s North-South Line currently relies on Hitachi’s SELTRAC CBTC system, which actively manages operations to permit trains to run at closer, safer intervals. By utilizing an advanced moving-block signalling architecture, CBTC continuously tracks train speeds and locations via continuous two-way digital communication. Upgrading and expanding this architecture on an operational railway requires most critical integration and testing works to occur during the brief nightly non-operational hours to prevent commuter disruption.
