Tender Notice
Summary of the contracting process

Colas Rail Limited is seeking experienced manufacturers to supply overhead catenary system switches and disconnectors for incorporation into the V360 OCS design range for HS2. The equipment must meet the project’s technical, operational, safety, quality and performance requirements. This is a goods opportunity covering railway materials, with associated construction and electrical materials. Delivery is for HS2 works in London. The requirement is suited to manufacturers of railway electrification equipment, overhead line components, electrical switching equipment or related rail infrastructure products. Suppliers will need to provide products compatible with the V360 OCS system and suitable for use within the HS2 project environment. The buyer has identified the opportunity as suitable for small and medium-sized enterprises, broadening its relevance to specialist manufacturers and established component suppliers.

The process has reached the tender stage: Colas Rail Limited invited suitably experienced manufacturers to submit offers. Tender proposals were to be submitted by email to Colas Rail by 16 September 2026, while the stated tender period ends at 4pm on 2 September 2026; suppliers should resolve this deadline directly with the buyer. The contract is scheduled to run from 1 October 2027 to 31 August 2030. Its estimated value is between £1,000,000 and £2,500,000. The procurement is for goods and is presented as a single requirement rather than separate lots. Proposals will need to demonstrate compliance with the V360 design range and HS2’s technical, operational, safety, quality and performance requirements. Questions are to be sent by email to Colas Rail during the tender process.

This opportunity suits manufacturers with proven experience designing, producing and supplying railway switches, disconnectors or comparable high-voltage electrical equipment for overhead electrification systems. Strong candidates will understand railway infrastructure environments and be able to demonstrate that their products satisfy demanding technical, operational, safety, quality and performance requirements. Suppliers should have the engineering capability to align equipment with the V360 OCS design range, together with production capacity, quality assurance and supply-chain control sufficient for a major rail project. Experience of supplying equipment for HS2, other high-speed rail schemes, mainline electrification or similarly safety-critical infrastructure would be relevant. Specialist small and medium-sized manufacturers may be well placed to compete, provided they can evidence dependable manufacture, testing, documentation and delivery of compliant equipment.
