HS2 may be politically contentious, but on the ground Balfour Beatty’s work on the future Old Oak Common station in West London has become a flagship demonstration of what the UK contractor can deliver on complex, multi-billion pound rail infrastructure. The company is a core member of the Balfour Beatty Vinci Systra (BBVS) joint venture building what government has called the country’s largest new railway station, a project that will ultimately connect HS2 services with the Elizabeth line and Great Western Main Line.

What Balfour Beatty is building at Old Oak Common

Old Oak Common is being constructed as a major interchange with 14 platforms, including 6 high-speed platforms in a 1-kilometer underground box for HS2 and 8 conventional platforms at surface level for the Elizabeth line and Great Western services, making it one of the most complex station builds currently under way in Europe. The BBVS joint venture is responsible for the station’s main works, covering extensive excavation, structural concrete, platforms and concourse construction under a contract valued at around £1 billion when it was awarded. The official HS2 project page describes Old Oak Common as the UK’s largest newly built railway station.

The station design includes a vast light-filled concourse above the high-speed platforms, with a distinctive arched roof structure using structural steel and glazing to bring natural light down onto the platforms and passenger areas. Construction has involved deep piling, diaphragm walls and excavation to accommodate the below-ground high-speed platforms while maintaining rail operations nearby and managing logistics in a densely populated urban environment in West London. Temporary works and phased construction sequencing are critical, as the project team must coordinate deliveries, spoil removal and heavy lifting within tight site boundaries while minimizing disruption to neighboring communities and existing rail lines.

Beyond the station box itself, Balfour Beatty and its partners are delivering associated infrastructure such as approach structures, access roads and utilities diversions, laying the groundwork for a broader redevelopment of the Old Oak and Park Royal area that planners expect to transform into a major new London district. The UK government has presented Old Oak Common as a catalyst for thousands of new homes and jobs in West London over the coming decades, positioning the station as both a transport asset and an urban regeneration anchor. A UK government update on HS2 highlighted Old Oak Common’s role in unlocking local regeneration and connecting multiple rail services.

From a technical standpoint, the project showcases Balfour Beatty’s capability across heavy civils, rail systems integration and large-scale station construction. Coordinating the future high-speed railway elements with existing and planned Network Rail and Transport for London services requires detailed interface management and extensive digital modeling to sequence works, manage risk and ensure long-term maintainability. Environmental measures, including the reuse of excavated material and efforts to limit noise and dust during construction, are part of HS2’s broader sustainability framework that BBVS has to implement on site.

For Balfour Beatty, Old Oak Common sits within a broader portfolio of UK transportation projects, but it stands out due to its scale, visibility and long construction timeline. The station is expected to become the London terminus for HS2 services after the curtailment of the Euston section in the government’s revised HS2 plans, which increases the operational importance of the site and, in turn, underscores the strategic relevance of Balfour Beatty’s delivery performance. Investors who follow the contractor’s project mix often look at HS2 packages, including Old Oak Common, as key contributors to its UK order book and revenue visibility.

Within that context, the HS2 Old Oak Common station works underline how much of Balfour Beatty’s value proposition rests on long-duration, government-backed infrastructure contracts with complex engineering requirements. The company has repeatedly pointed to its HS2 participation when discussing its UK Construction segment and long-term pipeline in investor communications, framing these projects as emblematic of its technical depth and risk management approach. Balfour Beatty’s original joint venture announcement for Old Oak Common emphasized both the contract size and the station’s role as a major HS2 hub. Shares of Balfour Beatty (GB0002422382) last traded on the London Stock Exchange at around GBX 381 on 06/13/2026.
