What we are doing
In April 2024 we started work on the Old Oak Common (OOC) tunnel connecting the Victoria Road Crossover Box to the to the Old Oak Common station site on Old Oak Common Lane. We’ll finish building this tunnel in late 2025, and works will be 24 hours a day, 7 days a week when required.
The 360-metre long OOC tunnels will be 12 metres below ground (to the crown of the tunnel). The tunnel will be built using a sprayed concrete lining (SCL) method, involving rapidly spraying the excavated ground with concrete to stabilise it to form the permanent tunnel lining.
Unlike bored tunnels, which are built using a tunnel boring machine, the SCL method allows variation in the tunnel shape and diameter of the tunnels, which are required in this location. The width of the tunnels varies as they approach Old Oak Common Station to allow for track separation as trains are changing tracks when travelling to and from the station.
