## Summary

Network Rail Infrastructure Limited has completed a public procurement process for the provision of a Thunderbird Incident Response Locomotive Service.

The procurement utilised an open, competitive flexible procedure under special utility regulations, covered by the GPA and CPTPP agreements. The contract, executed under the award and contract stages, was signed on 24th December 2025, and will commence from 8th January 2026 running until 8th January 2029, with an option for a three-year extension. Colas Rail Ltd, located in London, has been awarded this service contract valued at £10,704,674.40, involving repair and maintenance services related to railways, classified under CPV code 50220000.

This tender offers businesses in the railway maintenance industry substantial growth opportunities, particularly those equipped to provide large-scale, ongoing service operations. Businesses of a similar scale to Colas Rail Ltd, demonstrating capability in incident response within the rail sector, would find this opportunity aligned with their services. The contract's fixed pricing under a closed framework agreement ensures financial predictability, making it attractive for companies seeking stable growth through sustained partnerships with a central government public authority like Network Rail. Additionally, although the tender required a valid Track Access Agreement, the competitive nature of the procurement allowed various large-scale tenderers to participate, thus fostering an inclusive business environment.
