## Summary

Transport for Wales has concluded the procurement process for the provision of engineering trains, on-track machines, and associated services for the Core Valley Lines (CVL) works. This procurement falls under the services category and has been completed through a direct award to Network Rail Infrastructure Ltd, a supplier with exclusive rights necessary for the contract due to their intellectual property and infrastructure integration. The contract, valued grossly at £5,940,000, commenced on 19 May 2026 and will continue until 14 May 2029, with potential extensions up to 2031. The services will be delivered primarily in the United Kingdom region of Wales (UKL) under the utilities special regime. This procurement was governed under the Procurement Act 2023, specifically under the legal basis outlined in UKPGA 2023/54 and executed by a public authority - sub-central government, reflecting Welsh devolved regulations.

This tender represents a significant opportunity for businesses involved in railway transport services and related sectors, particularly those capable of leveraging large-scale projects that align with infrastructure and engineering service requirements. Firms that specialise in advanced railway technologies, possess exclusive capabilities, and have the necessary approvals to integrate with existing infrastructure could greatly benefit from this type of government contract. The nature of the direct award highlights the importance of being ahead in innovation and compliance, providing a competitive edge to businesses holding proprietary technologies or strategic partnerships with infrastructure owners like Network Rail. The extended period and potential renewals offer long-term business growth, making it an advantageous proposition for companies seeking to expand their operations within the UK rail industry.
