Summary of the contracting process

Network Rail Infrastructure Limited procured the collection, overhaul and delivery of approximately 2,500 wheelsets a year across its UK fleet. The services cover rolling-stock and locomotive wheelset maintenance, including overhaul of wheelsets and components such as axles, bearings, brake discs and gearboxes. Work must follow Network Rail technical specifications and supports five operational groupings: Y25/27 & VNH1, Y33 RDT MPV T2 & OLET, MPV T1, Y33 RHTT, and Mixed Wheelset Types. The requirement is structured as a multi-supplier framework, with call-offs issued through purchase orders. It covers the whole of the United Kingdom and is relevant to rail engineering, rolling-stock maintenance, wheelset overhaul and associated component refurbishment businesses.

The procurement is complete and has been awarded through a selective competitive flexible procedure under a framework agreement. DB Cargo (UK) Limited was awarded lots Y25/27 & VNH1, Y33 RHTT and Mixed Wheelset Types; Pullman Rail Ltd was awarded Y25/27 & VNH1, Y33 RDT MPV T2 & OLET, MPV T1 and Y33 RHTT; Lucchini Unipart Rail Limited was awarded Y25/27 & VNH1 and Y33 RHTT; and Arlington Fleet Services Ltd was awarded Y25/27 & VNH1, Y33 RHTT and Mixed Wheelset Types. Each award is valued at £30.9 million excluding VAT (£37.08 million including VAT). Awards were dated 2 June 2026. Contracts were signed between 2 and 22 July 2026, with periods ending between 1 and 21 July 2031 and possible extensions to July 2034. Evaluation weighted technical quality at 65% and commercial price at 35%.

This outcome shows sustained Network Rail demand for high-volume wheelset overhaul across varied fleet types, with resilience supported by multiple suppliers and primary, secondary and approved-supplier roles. A credible future competitor would need demonstrable capacity for different wheelset types, dependable collection, overhaul and delivery arrangements, and turnaround times suited to operational requirements. Evidence should cover technical methodology, delivery planning, risk management, operational readiness, contract organisation and strong reporting and issue-resolution processes. RISAS or equivalent accreditation, compliance with Network Rail standards, robust health and safety controls, and suitably qualified key personnel are central requirements. Environmental management, carbon reduction, circular-economy measures and social value also influence selection, alongside competitive unit rates and sound financial standing.
