HS2 launches hunt for Overhead Catenary System contractors

Overhead Catenary System, HS2

HS2 Ltd has begun the search for specialist contractors to deliver the Overhead Catenary System (OCS) that will provide power to the high-speed trains

Following on from the government’s green light for the start of construction, this rail systems contract, worth an estimated £300m, will provide valuable opportunities for companies across the UK recovering from lockdown.

OCS contracts

The winner of the Overhead Catenary System contract will be responsible for additional stages of design as well as manufacture, supply, installation, testing and commissioning of the HS2 systems.

OCS will be a single stage procurement, with the successful bidder delivering two separate contracts covering Phase One and Phase 2a – from London to Crewe, where HS2 services will join the existing west coast main line.

The system will cover 589km of track, including 62 viaducts, 293 bridges and 15 tunnels. The successful bidder will be expected to work closely with HS2’s other rail systems suppliers to ensure integration of its design as well as testing and commissioning.

HS2 will use the V360 OCS design range under licence from SNCF Reseau – the first system in Europe to be certified for speeds of up to 360km/h. The licence agreement allows the OCS contractor to go to the components market to find the most competitive supplier, opening up opportunities for smaller suppliers across the UK.

A shortlist is expected to be announced in the summer with the contract award in 2022.

HS2 Ltd’s procurement and commercial director, David Poole, said: “Our state-of-the-art rail systems will allow HS2 to run fast, frequent, high capacity services across the network – offering low carbon travel options for millions of people across Britain.

“The overhead catenary is a vital part of the project and the successful bidder will play a crucial role in keeping the HS2 network running safely and reliably.”

HS2 current progress

Earlier this week, HS2 also launched contract opportunities worth an estimated £498m, covering Tunnel and Lineside Mechanical and Electrical equipment across Phase One and 2a. This includes the tunnel services within the shafts, tunnels and cross-passages and low voltage power services and distribution in the open route.

Legislation to build Phase 2a (Birmingham-Crewe) is currently in the Lords with Royal Assent expected later in the year. All of the recent rail systems contract opportunities have included provision for work on 2a, with contracts expected to be signed once the legislation is in place.
