Six HS2 platforms completed at Old Oak Common in Acton
HS2 Ltd has confirmed that the first six underground platforms at Old Oak Common station are complete. The 450-metre platforms form three islands inside a deep box structure in the Acton area of Ealing. The work marks visible progress on a major rail hub that will also serve the Elizabeth line and other services.
HS2 Ltd has confirmed completion of the first six underground platforms at Old Oak Common station in west London, in the Acton area of the London Borough of Ealing.
Each platform is 450 metres long and together they form three islands. Construction used almost 2,000 prefabricated concrete slabs, each measuring 2 by 4 metres and weighing four to five tonnes. The slabs were installed from both ends of an 850-metre underground box that sits 20 metres deep.
The work was carried out by partner Balfour Beatty Vinci SYSTRA.
In future the station is intended to be a major interchange. Alongside the six HS2 platforms, eight above-ground platforms are planned for the Elizabeth line, the Great Western Main Line and Heathrow Express.
For residents of Ealing and Acton, the completed platforms are a clear sign of progress on the largest railway investment in the area.
