ETCS System Safety Assurance

The Western ETCS L2 project, commissioned in November 2023, represents the UK’s first mainline deployment of ETCS Level 2. Synergy Rail was competitively appointed through all prior phases of the project since 2015 via the W&W Safety Assurance Framework (CP6), delivering end-to-end system assurance from GRIP 3 feasibility through to system commissioning and early post-commissioning support.

Key services provided included:

Development of the safety and acceptance strategy

Interoperability verification and regulatory support

Management of product acceptance processes.

Oversight of all V&V activities and testing phases

Completion of safety justifications for operational non-compliances Synergy Rail’s contributions were highly commended by both FCCS SRP and ORR, with ORR explicitly recommending their methodology be used as a template for future ETCS deployments.

Justification

With the project now in a “post-commissioning enhancement and non-compliance resolution phase”, continuity of system knowledge, safety case integrity and structure, and regulatory confidence are critical to the successful engagement with 4SP/FCCS-SRP and W&W -SRP and deployment.

Synergy Rail is uniquely qualified for the following reasons:

Unmatched technical familiarity with the deployed system, including contractors architecture, assurance processes, structure of the System Safety Case , Interoperability arguments, the Technical File and bespoke safety justifications used in deployment of the current ETCS L2 Solution.

End-to-end project involvement, eliminating the onboarding risks and delays of a new provider Demonstrated regulatory credibility, having delivered a model process acknowledged by the ORR and FSSC-SRP have engendered trust and confidence in submissions streamlining both time to resolution and reduced the “Pull” on critical limited Regulator and Panel member involvement.

Established relationships with Network Rail Engineering, Assurance Panel members and project teams

Appointing an alternative provider would likely increase final cost, delay critical updates, and undermine continuity of safety oversight and drive increased Panel engagement in submissions and assessment time. Therefore, a Direct Award is the most practical, economical, and low-risk procurement approach for the Industry as a whole.
