Siemens Mobility recently held the world's first live demonstration of "Signaling X" for metro systems at the Singapore Railway Test Centre (SRTC). The breakthrough of this technology lies in integrating a Communication-Based Train Control (CBTC) system into a centralized, cloud-ready infrastructure, and running safety-critical functions through Commercial Standard Train Control (COTS) hardware, which will significantly improve the operational efficiency and energy savings of urban rail transit.
Improved operational efficiency by 20% and energy savings by 30%, resulting in shorter bus intervals.
As global urban transportation demand rises, Siemens Mobility, through its self-developed Distributed Smart Safe System (DS3) platform, is transferring safety-critical functions that traditionally relied on dedicated hardware to run on standard IT hardware.
Siemens claims that this architecture allows trains to operate safely at shorter intervals, improving overall operational efficiency by up to 20% while saving up to 30% on energy consumption. For passengers, this means more frequent train services and shorter waiting times.
Extending from main lines to subways, a "Signal Data Center" will be established.
"Signaling X" was first unveiled at the 2024 Berlin Rail Show (InnoTrans) and applied to mainline railways, and is now being further expanded to the mass transit market.
Its core concept is to integrate turnout control, signaling system, and operation control system into a virtualized, centralized "Signaling Data Center". Through standardized API connections, Signaling X can simultaneously execute safety-critical functions (such as interlocking logic) and non-safety-critical systems (such as timetable management) on commercial hardware of the same specifications, thereby breaking the previous limitations of high hardware and software binding.
In collaboration with MSI Global, the event highlighted cybersecurity and scalability.
Marc Ludwig, CEO of Railway Infrastructure at Siemens Mobility, said this was the first time Signaling X had been demonstrated live in a CBTC test environment, and he especially thanked their partner MSI Global for their assistance.
Marc Ludwig emphasized that Signaling X symbolizes a significant milestone in the digital transformation of public transportation. Through its open interface and cloud-ready architecture, it not only possesses high scalability and redundancy but also has built-in cybersecurity mechanisms, laying the foundation for a more flexible and forward-looking railway ecosystem in the future.
