This week, Siemens Mobility carries out the world’s first live demonstration of metro operations with Signaling X at the Singapore Rail Test Center (SRTC), in front of mass transit operators and journalists from around the world. As global mobility demand continues to rise, this breakthrough brings Communications-Based Train Control (CBTC), the state-of-the-art system for metro and urban networks, into a centralized cloud-ready infrastructure, a signaling data center. Safety-critical functions run on commercial off-the-shelf (COTS) hardware with Siemens Mobility’s Distributed Smart Safe System (DS3) platform. The result: 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 is now ready for the mass transit market.
"Today marks a milestone in the digital transformation
of mass transit as we unveil Signaling X in a live urban rail environment here
in Singapore. Signaling X brings together various signaling systems onto one
platform, expanding capabilities through open interfaces,"
says Marc
Ludwig, CEO of Rail Infrastructure at Siemens Mobility. "Our
groundbreaking solution has already demonstrated its reliability in mainline applications
as a globally proven platform with a strong track record. Today is the first
live showcase in a CBTC mass transit test setting, and we are grateful to MSI
Global for partnering with us to present Signaling X."
Cloud-ready platform: Future of Railway
Signaling X represents a groundbreaking advancement in
signaling and control for both mainline and urban rail. This cloud-ready platform
integrates interlockings, signaling systems, and control systems into a
centralized, virtualized data center. By deploying safety-critical railway
functions, like interlocking logic, and non-safety systems such as timetable
management and traffic optimization on the same type of commercial off-the-shelf
hardware and through standardized 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 utilizes 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.
