The first high-speed platforms at the railway station slated to become Britain’s busiest have been constructed at Old Oak Common.

The six new completed platforms, which are 450m underground, were revealed as part of the HS2 expansion on 13 August.

Old Oak Common is set to be the UK’s “busiest, best-connected station” with 14 platforms – six for high-speed services and eight at ground level for conventional services on the Elizabeth line, Great Western Main Line and Heathrow Express.

The new underground platforms will be served by HS2’s fleet of new high-speed trains, with the station in west London designed to reach more than 100 destinations.

According to HS2, up to 250,000 daily passengers will use the station for connections between London, the Midlands, the north of England and Scotland.

Connections at Old Oak Common will utilise existing lines including the West Coast Main Line, Great Western and Elizabeth line, where the station will become the 42nd stop.

Work began to construct the high-speed platforms in April 2025.

HS2 engineers expect the first platform slabs for overground platforms to be installed later this year, with the first part of the station’s roof planned to go up in early 2027.

Kim Kapur, HS2’s Old Oak Common area director, said: “Going into the underground box at Old Oak Common, you can immediately visualise how it will look as an operational station, including where passengers will board or alight HS2's brand new trains. The scale of the work - and the station now taking shape - is remarkable.

“However, there is much more to do. This includes construction of the conventional, surface-level platforms, completion of tunnels either side of the underground box and installation of the impressive station roof, which will begin next year.

“Old Oak Common will be transformative for the local area, providing a new transport hub, with a new vibrant neighbourhood developing around it.”
