UK5 - Transparency Notice
Summary of the contracting process

Chiltern Rail Limited is buying new and repaired materials for its Class 165 and Class 168 diesel multiple-unit trains. The requirement covers rolling-stock parts used on these fleets, which Chiltern Railways operates. Delivery is in the United Kingdom. This is a supply requirement for rail components, rather than for train operation, maintenance services or infrastructure works. The materials include repairable spares as well as new supplies. The buyer says some repairable materials are no longer available to purchase new, and the supplier may need to provide replacement or revised materials if existing items become obsolete or are superseded.

The procurement is complete and has been awarded by direct award to Alstom Engineering and Services Limited. The stated basis was that Alstom is the original equipment manufacturer and design authority for the fleets, retains intellectual property rights over covered materials, and holds spare materials, including items no longer available new. The award value is £4 million excluding VAT (£4.8 million including VAT). The contract period runs from 1 January 2027 to 31 December 2031. A contract signature was scheduled for 1 November 2026. There is one lot, marked suitable for small and medium-sized enterprises. The award allows materials to be added if they become obsolete or if Alstom holds the intellectual property rights and is the sole source. The award is recorded as pending.

For suppliers considering comparable rail-materials work for Chiltern Railways, this award shows a continuing requirement for parts for its Class 165 and Class 168 fleets, including both new components and the repair or supply of existing spares. Credibility on a future requirement of this kind would depend on being able to supply materials compatible with these specific train classes and to support repairable items, including spares that may no longer be available new. Design authority, control of intellectual property rights and access to original or replacement materials were central to the buyer’s stated rationale for selecting Alstom. Suppliers without those rights or access would need to establish how they can meet the technical requirements and provide a dependable supply as specifications change when parts become obsolete or are superseded. The procurement was direct-awarded, rather than competed.
