## Summary

The Rail Safety Standards Board (RSSB) commissioned specialist research services to update its GSM-R radio failure model, supporting work on railway safety and operational risk. The scope covers updating the knock-on risk component, bringing the model into line with Safety Risk Model version 10, reviewing other key assumptions, recalculating the model results and producing a final report. The work requires quantified risk analysis, statistical techniques, current knowledge of the Safety Risk Model and a strong understanding of the rail industry, particularly rail safety. RSSB is based in London. The stated delivery geography covers the United Kingdom, Europe, the Channel Islands, the Isle of Man, British Overseas Territories and the rest of the world. This is a services requirement classified as research services, CPV 73110000.

This procurement has been awarded and is recorded as complete. The contract was awarded to Sotera on 12 June 2026 for £65,600, with delivery running from 13 June 2026 to 12 December 2026. The original tender deadline was 15 May 2026. The requirement was presented as a tender for services, with an estimated value of £65,600. The award covers the full GSM-R failure-model update described in the scope. RSSB identified the opportunity as suitable for voluntary, community and social enterprise organisations, but not for small and medium-sized enterprises. The award is active, and Sotera is the selected supplier. The procurement information does not state a separate lot structure or a detailed award-scoring breakdown.

For suppliers that did not win this procurement, the award demonstrates demand for specialist rail-safety modelling and quantified risk analysis from RSSB. A credible competitor for comparable work would need to combine statistical expertise with practical experience of failure modelling, risk quantification and the railway operating environment. Knowledge of RSSB’s Safety Risk Model, including the ability to work with successive model versions and revise underlying assumptions, would be important. The requirement also indicates a need to recalculate analytical results and communicate findings in a clear final report, so suppliers should be able to manage technical assurance, documentation and stakeholder-facing reporting as well as analysis. The scale and specialist scope suit established rail-risk consultancies or larger technical firms with experienced analysts and relevant railway safety capability.

## Notice
