From 10–14 November, Siemens Mobility is carrying out the world’s first live demonstration of metro operations with its Signaling X solution at the Singapore Rail Test Centre (SRTC), in front of mass transit operators and journalists from around the world.
As global mobility demand continues to rise, this breakthrough brings CBTC into a centralized cloud-ready infrastructure, a signalling data centrr. Safety-critical functions run on commercial off-the-shelf (COTS) hardware with Siemens Mobility’s Distributed Smart Safe System (DS3) platform.
This resulted in up to 20% higher operational efficiency and up to 30% energy savings, delivering more capacity and sustainable mobility by enabling more trains to run safely at closer intervals. Following its launch at InnoTrans 2024 and successful introduction in mainline rail, Signaling X solution is now ready for the mass transit market.
The demonstration “marks a milestone in the digital transformation of mass transit as we unveil Signaling X solution in a live urban rail environment in Singapore. Signaling X brings together various signalling systems onto one platform, expanding capabilities through open interfaces,” says Marc Ludwig, CEO of Rail Infrastructure at Siemens Mobility. ”
Signaling Signaling X represents a groundbreaking advancement in signalling and control for both mainline and urban rail. This cloud-ready platform integrates interlockings, signaling systems, and control systems into a centralised, virtualised data centre. By deploying safety-critical railway functions, like interlocking logic, and non-safety systems such as timetable management and traffic optimisation on the same type of commercial off-the-shelf hardware and through standardised APIs, it provides a seamless, efficient approach to rail operations.
Unlike proprietary systems that rely on older chip technology and occupy entire rooms with specially built electronics, Signaling X demonstrates that the software can run in systems worldwide on COTS standard hardware – simplifying infrastructure and reducing complexity.
The foundation of this innovation is the DS3, introduced in 2020, which utilises COTS hardware to ensure safety-critical applications operate securely within a scalable, redundant network. This cyber-secure environment enhances operational efficiency, offers significant energy savings, and reduces headways, paving the way for a more flexible and future-proof rail ecosystem.
