Helping build Britain’s future
HS2 is a major rail infrastructure project in the United Kingdom, aimed at creating a high-speed rail network connecting London to Birmingham. The project is designed to improve rail capacity, reduce travel times, and boost economic growth in regions outside London.
Since 2012, we've played a vital role in nearly every phase of the HS2 project, evolving from a provider of professional services to a trusted development and delivery partner. We are currently supporting delivery across five major contracts.

AtkinsRéalis has been instrumental in the procurement and evaluation of the £2bn rolling stock for HS2. Despite the challenges posed by the COVID-19 pandemic, our team successfully adapted to remote work, ensuring that the evaluation of tenders proceeded without delay. HS2 Ltd commended our flexibility and commitment to keeping the programme on track.
As part of a joint venture, we have provided comprehensive engineering support across both Phase 1 and Phase 2a of the HS2 project. Our responsibilities have included developing technical standards, managing design integration, and providing technical oversight for significant contracts. We achieved 100% client satisfaction and consistently met delivery KPIs over the past five years, becoming HS2’s ‘first line of defence’ in technical assurance.
We have offered extensive technical expertise in climate change adaptation, town planning, and environmental impact assessments. Our work has facilitated the seamless transition from project development to delivery, particularly in managing consents for major civil works.
As the prime consultant, we lead a diverse and agile team, providing Project Management Office (PMO) and programme controls services across HS2. Our work has included managing £3.6bn in potential cost savings and developing a collaborative planning process that ensures seamless integration across teams.
As the lead in a partnership, we have been supporting HS2 in the delivery and integration of all railway systems. Our role includes managing technical risks and developing readiness plans, leveraging our expertise from previous high-speed rail projects.

The Colne Valley Viaduct is a spectacular feat of UK engineering and ingenuity and we’re proud to have supported through preliminary design work.

Britain's longest rail bridge
In September 2024, HS2 made history by placing the final deck segment of a new viaduct that crowns it as Britain’s new longest rail bridge. This gently curved, 3.4-kilometre (2.1-mile) structure on London's north-western edge spans the Colne Valley near the M25 motorway and the village of Denham. It will carry high-speed trains to and from the capital at speeds of up to 320 km/h (200 mph).
With the viaduct's completion, the 3.3-kilometre Tay Bridge, which has held the title of Britain's longest rail bridge since 1887, has been surpassed. AtkinsRéalis contributed to this achievement by providing preliminary design work, including off-site build design, technical and architectural reviews, and complex dynamic analysis to ensure the viaduct's viability, all in line with new high-speed standards. HS2 is making a step change in how well-designed, major infrastructure connects communities and we look forward to continuing to support delivery.
What’s next?
As the project evolves amidst new economic and political landscapes, AtkinsRéalis continues to support HS2 and broader national rail initiatives, drawing on our extensive experience to ensure the successful delivery of integrated, future-proof transport solutions.
