Summary of the contracting process

London Underground Limited, with Transport for London acting as procuring organisation, is buying bespoke metal O-rings, seals, pistons, key pins, thrust washers, cylinder bolts and friction plates for Jubilee line train door engines. These are safety-critical replacement components intended for door engines across 63 trains. The parts are bespoke to the Jubilee line door-engine system rather than off-the-shelf items, and support the safe operation and reliability of the trains’ doors. Delivery is in the United Kingdom. The goods fall within railway rolling-stock parts.

The procurement is complete and has been awarded by direct award to Faiveley Transport Tamworth Ltd (Wabtec), the original equipment manufacturer that designed and manufactured the door-engine parts. The stated reason was that alternatives could be incompatible with the existing system and cause disproportionate technical and maintenance difficulties. The award is valued at £864,168 excluding VAT (£1,037,002 including VAT). The contract period runs from 13 October 2026 to 12 October 2028, with an option to extend for a further 12 months, to 11 October 2029. The stated quantities include 4,200 each of O-rings, seals and pistons; 2,100 key pins; 1,300 and 2,100 thrust washers; 16,800 cylinder bolts; and 1,300 friction plates. Quantities may change following sample testing.

For suppliers assessing future London Underground door-engine requirements, this award shows that compatibility with the existing Jubilee line equipment and the safety and reliability of train doors are central. The buyer selected the original equipment manufacturer because the parts are bespoke and a change of source could create technical difficulties in operation and maintenance. A credible competitor would therefore need to demonstrate that its components meet the established system requirements and safety standards, and that supplying them would not compromise maintenance or operational reliability. The requirement covers multiple types of precision metal and mechanical components in quantities suited to maintaining door engines across a sizeable train fleet. Experience with rail rolling-stock components, bespoke manufacture and safety-critical supply would be relevant evidence of capability.

Notice Information

Notice Title

Jubilee line Door Engine Kits

Notice Description

This procurement is for the supply of 4200 each of Bespoke Metal O Rings, 4200 each of Bespoke Seals, 4200 each of Bespoke Pistons, 2100 of Bespoke Key Pins, 1300 and 2100 x2 of Bespoke Thrust Washers, 16800 of Bespoke Cylinder bolt & 1300 each of Bespoke Friction plates. All these parts are safety critical components relating to the door engines of the Jubilee line fleet. These parts will be used for door engines across 63 trains.

Procurement Information

The reason for a direct award is that all components are bespoke to the Jubilee Line Door Engines and thus an off the shelf product won't satisfy system technical requirements. Faiveley Transport Tamworth Ltd (Wabtec) designed and manufactured parts such as the Door Engine. As these parts are directly related to the safe operation and reliability of the door system, it is critical to procure these parts from the original supplier (OEM) for the parts to be of the required quality standards to prevent any safety challenges in an operational train. Any changes to these parts being procured if sourced from alternate suppliers would have disproportionate technical difficulties during operation / maintenance and therefore drastically reduce reliability. This procurement is in line with: Paragraph 7, schedule 5, Section 41 of the Procurement Act 2023, wherein (a) a change in supplier would result in the contracting authority receiving goods, services or works that are different from, or incompatible with, the existing goods, services or works, and (b) the difference or incompatibility would result in disproportionate technical difficulties in operation or maintenance.
