HS2’s Future-Proofing Strategy: Tunnel Borers Buried for Euston Extension
In an effort to ensure the readiness of Euston as the ultimate terminus for HS2 (High-Speed 2), engineers at the Old Oak Common station in west London are employing a unique approach by burying tunnel boring machines on-site.
The objective is to prepare for the extension of the high-speed rail route into central London – its original designated destination.
Paused Euston Project Prompts Innovative Solution
After Transport Secretary Mark Harper’s announcement of a two-year pause on work at Euston due to escalated costs, the focus has shifted to Old Oak Common as HS2’s sole London station during the launch of services to and from Birmingham.
The creative strategy showcases the flexibility required in large-scale infrastructure projects, adapting to changing circumstances and maximizing resource utilization.
Preparation for the Unfinished Journey
Huw Edwards, HS2 Ltd’s project client for Old Oak Common, revealed that the construction team’s actions won’t hinder the continuation of the railway toward Euston.
He affirmed that they plan to lower two tunnel boring machines into the HS2 chamber at Old Oak Common, to be stored and utilized once the government approves the extension toward Euston.
The decision to invest in equipment that is strategically stored underscores the anticipation of future needs while acknowledging the pause in Euston’s development.
Ensuring a Parallel Path
While the commencement of HS2 passenger services is still years away, Edwards emphasized that preparations need to begin promptly to accommodate additional train tracks and development over the top.
The wider Great Western main line as part of the Old Oak Common expansion necessitates lowering the tunnel boring machines in 2024.
Balancing multiple aspects of a project ensures seamless integration and avoids potential roadblocks during later phases of development.
Confronting Challenges for Continuous Progress
Edwards highlighted that, despite the pause at Euston, the project aims to avoid hindrances to its ultimate destination.
The tunnelling work required for the Euston direction could proceed in tandem with daily operations at the Old Oak Common transport hub.
Symbolic Ceremonies and Practical Readiness
The burial of the two tunnel boring machines will be marked with a ceremony, including a Christian service involving a statue of St. Barbara, the patron saint of tunnelling.
These heavy machines will undergo regular maintenance while stored underground, ensuring their operational readiness for potential use.
Delayed Launch and Ongoing Commitment
HS2’s launch, initially slated for 2026, faces a delay due to construction challenges and rising costs.
Currently, Euston is not expected to host HS2 trains until 2041 at the earliest.
Despite reports suggesting Old Oak Common as a permanent terminus, Prime Minister Rishi Sunak remains committed to delivering Euston terminal.
The commitment to the original terminal underlines the significance of the project and its role in reshaping transportation infrastructure.
Anticipating Passengers’ Choice
Huw Edwards emphasized that Old Oak Common’s connections, including the Elizabeth line, offer convenient access to London’s prominent areas.
He anticipates that passengers, accustomed to Old Oak Common, will continue their journey even after the extension to Euston, reflecting the evolving travel patterns driven by enhanced connectivity.
Revolutionizing Rail Infrastructure
Upon completion, Old Oak Common is set to become the UK’s largest newly built railway station, accommodating 14 platforms, with six designated for high-speed services.
The station’s ambitious design aims to handle approximately 250,000 passengers daily, serving as a vital hub for HS2’s operations.
The integration of various transportation modes and the station’s expected capacity highlight the role of infrastructure projects in enhancing regional connectivity and fostering economic growth.
