Project Profile: High Speed 2 (HS2) Railway, UK

High Speed 2 (HS2) is a multi-phase, high-speed rail infrastructure project in the United Kingdom designed to enhance national connectivity between London, the Midlands, and the North. The project involves the construction of a new dedicated high-speed line, advanced rolling stock, and integrated station hubs, representing a significant upgrade to the UK’s conventional rail network and a major undertaking in civil engineering.

Project Fact Sheet

AttributeDetails
Project NameHigh Speed 2 (HS2)
LocationUnited Kingdom (London, Midlands, North of England)
LengthApproximately 330 miles (531 km) for the planned network.
Max Operational Speed225 mph (362 km/h)
Estimated CostCirca £106 billion (revised estimate)

Technical Specifications

The HS2 project is defined by its advanced engineering and technological systems. The route is a ‘Y’ shaped network, with Phase 1 forming the trunk from London Euston to Birmingham Curzon Street. The infrastructure is designed to accommodate high-speed trains with a capacity of over 1,100 passengers per unit, operating at speeds up to 225 mph (362 km/h). A significant portion of the route involves complex civil engineering, including over 30 miles of tunnels on Phase 1 alone, such as the Chiltern and London Tunnels, to mitigate environmental and noise impact. The project will utilize state-of-the-art digital signalling systems (ETCS Level 2) for safe and efficient high-frequency operation, integrating seamlessly with the existing network at key interchanges.

Key Takeaways

  • Capacity and Economic Rebalancing: HS2 is engineered to solve critical capacity constraints on the UK’s Victorian-era rail network, freeing up pathways for more local, regional, and freight services. By improving connectivity, it aims to stimulate economic growth and investment in the Midlands and Northern England.
  • Technological Advancement: The project represents a significant technological upgrade for UK rail, introducing 225 mph (362 km/h) capable rolling stock and advanced digital signalling systems, setting a new standard for national infrastructure.
  • Enhanced National Connectivity: HS2 aims to fundamentally reduce inter-city journey times between London, Birmingham, and Manchester, strengthening economic and social ties between the UK’s largest economic centres.

Frequently Asked Questions (FAQ)

When will HS2 open?
HS2 is being opened in phases. The first services for Phase 1, connecting London and Birmingham, are anticipated to commence between 2029 and 2033. The subsequent phases connecting to Crewe and Manchester are scheduled for completion in the late 2030s to early 2040s.

Who is building HS2?
The HS2 project is publicly funded and managed by the government-owned company, HS2 Ltd. The primary construction and engineering works are delivered by a series of joint ventures composed of leading international and British firms, including Balfour Beatty, VINCI, Costain, Skanska, Ferrovial, and BAM Nuttall.
