SINGAPORE: Metro operator SBS Transit has extended Siemens Mobility’s Long-Term Service Support contract for the signalling systems on the 44 km fully-automated Downtown Line.
The ‘outcome-based’ agreement runs for 22 years from January 1 2026 until December 31 2047, and covers obsolescence treatment, technology refresh and upgrades, including security-related measures.
The new contract builds on an LTSS arrangement awarded in May 2024 which covers spares support, technical support and obsolescence monitoring. Together, these agreements establish a long-term framework under which Siemens Mobility, as original equipment manufacturer, provides life-cycle management services.
There will be a transition from reactive to proactive obsolescence management, with all known and foreseeable obsolescence affecting the DTL signalling subsystems and components to be identified and addressed through structured measures. This will include the assessment and definition of required development and qualification work for suitable redesigns, the implementation of redesigns at subsystem or component level and the introduction of qualified replacement parts into applicable signalling equipment. This will be supported by adequate spare parts inventory and continuous monitoring of component lifecycles to prevent future disruptions.
The contract also includes structured system updates to address evolving security requirements, with Siemens Mobility to review system performance and configuration on an ongoing basis to ensure that new or updated hardware and software components are compatible with the local operating environment and can be integrated without compromising existing functionality.
‘By combining lifecycle services with proactive obsolescence management, targeted technology refresh and security upgrades, we ensure that the signalling system remains technically up-to-date, highly available and fully integrated into the existing infrastructure over more than two decades’, said Elmar Zeiler, CEO of Siemens Mobility Customer Services, on December 8.
