The job was awarded by the SCS Railways, a JV between Costain and Skanska and Austrian tunnelling contractor Strabag, which is building 26 miles of tunnels leading from Euston to the outskirts of London via Old Oak Common station.

The works, which are expected to employ around 100 Cementation staff, are scheduled to be completed in 2024.

Skanska has tried to offload 拢62m turnover Cementation twice since 2018 but opted to keep it when it failed to find a buyer for the price being offered.

SCS Railways is also building the Victoria Road Crossover Box close to Old Oak Common Station.

The huge underground box, which has the volume of 55 Olympic swimming pools, will allow trains approaching and departing from Old Oak Common station to swap tracks at speeds of up to 62km/h.
