HS2 Tunnelling to Euston Commences: A New Era for High-Speed Rail in London

The first of two colossal tunnel boring machines (TBMs) has officially begun its journey from Old Oak Common to Euston Station, marking a significant milestone for the High Speed Two (HS2) project. This crucial step brings the high-speed railway closer to its central London terminus, promising substantial economic benefits and improved connectivity.

Key Takeaways

Tunnelling for HS2 into Euston has officially begun, with the first of two TBMs starting its 4.5-mile journey.
This development is seen as essential for unlocking HS2’s full economic potential, with estimates suggesting up to £41 billion could be added to the UK economy by 2053.
The project is expected to support approximately 34,000 jobs through redevelopment around Euston.
The start of tunnelling signifies renewed momentum for HS2, addressing previous concerns about the line potentially terminating at Old Oak Common.

A Monumental Engineering Feat

The TBM, named ‘Madeleine’ after Madeleine Nobbs, former president of the Women’s Engineering Society, weighs a staggering 1,624 tonnes. As it advances, it simultaneously excavates the tunnel and constructs its lining using pre-cast concrete segments. This process will remove over 1.5 million tonnes of excavated material, much of which will be transported by rail to minimise environmental impact and disruption.

This operation is one of the most complex engineering challenges on the HS2 project, with the two parallel tunnels requiring the installation of over 8,000 pre-cast tunnel rings. The entire tunnelling phase is anticipated to take between 12 to 18 months.

Unlocking Economic Potential

Bringing HS2 into Euston is considered vital for realising the project’s full economic benefits. Estimates suggest that redevelopment around Euston could inject approximately £41 billion into the UK economy by 2053, creating around 34,000 jobs. Furthermore, HS2 is projected to contribute £10 billion to the west London economy over the next decade, fostering the development of new homes and employment opportunities.

Rail Minister, Lord Hendy, expressed his enthusiasm, stating, “It was brilliant to switch on the tunnel boring machine at Old Oak Common today – not just because it’s an engineering marvel – but because it brings HS2’s journey to Euston another step closer to reality.”

A Modern Transport Hub for London

The plans for Euston extend beyond the new HS2 station, envisioning a fully integrated transport hub. This will combine the new HS2 facilities with a redeveloped mainline station and upgraded London Underground services. A new body, the Euston Delivery Company, will oversee both the transport improvements and wider commercial development at the site.

Broader Railway Modernisation

The commencement of tunnelling to Euston underscores the government’s commitment to modernising Britain’s railways. This initiative aligns with wider reforms aimed at consolidating rail services under Great British Railways, with the objective of enhancing value, reliability, and passenger experience across the network.

With over 33,000 people currently employed on HS2, the project continues to be a significant driver of employment and economic activity. The successful completion of the Euston tunnels is seen as a crucial step in delivering faster, more reliable journeys and freeing up capacity on existing rail lines.
