    The future of railway operations

    Five building blocks for secure and scalable railway digitalization.

    Standardized infrastructure and operations

    Replace fragmented, application-specific environments with reusable platform and operating components that support standardization and scaling across applications, sites and manufacturers.

    Safety and cybersecurity by design

    Integrate isolation, secure communication, monitoring and other defined platform properties to support safety and cybersecurity requirements within the specific system context.

    Auditability and reusable evidence

    Make configurations, changes, operating conditions and security events traceable. Reusable evidence can support Safety, Security and approval processes across the lifecycle.

    Resilience and digital sovereignty

    Address growing requirements for availability, recovery, cyber resilience and digital sovereignty through controlled and transparent platform and operating models.

    Clear roles and shared responsibility

    Define responsibilities between application owners, platform operators, system integrators and infrastructure operators. The platform supports the safety case without taking over application-level safety responsibility.

    FAQs

    Secure Cloud for Safety-Critical Railway Applications.

    The Safe T-Cloud is a standardized, sovereign and auditable operating platform designed to support the operation of safety-critical railway applications under controlled and verifiable conditions.
    The reference architecture considers safety-critical applications such as components of digital interlocking systems, ETCS and other SIL-relevant railway applications.
    No. The functional safety responsibility remains with the respective application and system owners. The platform operator is responsible for the defined technical and operational properties of the platform.
    The platform provides standardized infrastructure, security and operational services such as isolation, monitoring, logging, identity management, backup and recovery. Defined platform properties and reusable evidence can support application-specific safety and security cases.
    Relevant frameworks include RAMS, railway safety standards, cybersecurity standards and regulations, resilience requirements and railway-specific requirements such as TSI CCS. Their interaction needs to be assessed within the specific system context.

    Standardized and reusable platform and operating components can reduce duplicated infrastructure, integration and operational effort while supporting faster roll-outs, centralized operations and more consistent evidence management.

    A successful implementation requires cooperation between infrastructure operators, railway technology providers, platform operators, assessors, regulators, hardware providers and security partners, with clearly defined roles and responsibilities.
