BELGIUM —Siemens Mobility and Infrabel have signed an 11-year framework agreement valued at approximately €215 million to modernize and maintain Belgium’s Operational Control System (OCS), the digital infrastructure used to manage railway traffic across the country. The programme covers the ongoing renewal of signaling software and operational hardware supporting rail control centers.
The agreement establishes a long-term mechanism for upgrading mission-critical railway control technology rather than delivering a single one-off system deployment. A four-year rolling roadmap, reviewed through annual planning between the two organizations, will allow technical priorities and resource requirements to be adjusted during the contract period.
Cybersecurity is a central component of the modernization. The programme includes dedicated security oversight and continued alignment with rail cybersecurity requirements, including IEC 62443 and ISO 27001. The upgraded environment will also incorporate a modern operator interface and next-generation signaling architecture intended to support the continuous evolution of control systems.
The investment is significant for Belgium’s rail sector because the OCS environment supports one of Europe’s most intensively used railway networks, where passenger and freight services operate across the same national infrastructure. More resilient control and signaling systems can support operational continuity, safety and network capacity as traffic requirements and digital dependencies increase.
For railway infrastructure operators, the agreement illustrates the growing importance of long-duration modernization programmes covering software, hardware, maintenance and cybersecurity together. It also creates a continuing technology and services requirement for Siemens Mobility over the 11-year period, while giving Infrabel a structured framework for managing technology upgrades without relying on isolated modernization cycles.
The programme is expected to affect Belgium’s rail technology and infrastructure ecosystem through demand for signaling engineering, software development, cybersecurity, system maintenance and specialized operational expertise. Siemens Mobility will provide support through its Belgian capabilities, while Infrabel remains responsible for the country’s railway infrastructure management and traffic operations.
Siemens Mobility is the rail-focused business of Siemens, providing rolling stock, rail infrastructure, signaling, automation and digital mobility systems. Infrabel is Belgium’s national railway infrastructure manager, responsible for managing and maintaining the country’s rail infrastructure and supporting the operation of passenger and freight traffic.
