A monumental feat of engineering is hidden beneath the Chiltern countryside, as HS2's two 10-mile tunnels stand ready to transform the UK rail network. The spectacular underground structure is a testament to the country's ability to deliver on ambitious infrastructure projects – but also highlights the challenges faced by those in charge.
The £80 billion plus budget for the high-speed railway has seen many setbacks and delays, sparking criticism of the government's handling of the project. With the original timeline now set back by several years, some argue that the true cost of HS2 will exceed estimates of £150 billion.
But amidst the controversy, there are glimmers of hope. A £32 billion investment has created over 1,800 jobs at a single worksite in Buckinghamshire, with workers completing a staggering 33 months of tunnel construction in just 24 hours a day, seven days a week.
HS2's chief executive Mark Wild has vowed to restore the project's momentum and efficiency, introducing radical changes aimed at driving down costs. This includes revamping the supply chain and implementing more productive working practices – measures that will aim to bring the entire build back on track within the next year.
Visitors to the Colne Valley viaduct have also been impressed by the innovative design and engineering of the structure. A 2.2-mile-long rail bridge spanning two reservoirs, it was built using over 112,000 tunnel segments – a feat that would be impossible without modern technology.
In addition, HS2 has implemented cutting-edge noise reduction techniques to minimize disruption to local residents. A funnelled opening design has been introduced at the entrance and exit points of the tunnels, reducing sonic booms by up to 50%.
