Under the contract, ATC will design and install track, overhead lines and mechanical and electrical equipment to fit out the 21km of twin tunnels currently being bored under the streets of London. The contract covers the entire tunnelled and surface sections of the Crossrail route between Royal Oak, Pudding Mill Lane and Plumstead Portals.
Design work will commence immediately, with the fit-out works starting in 2014. Costain and Alstom have also won the £15m contract for the design, construction and commissioning of the system that will provide traction power for the trains in the central tunnelled section of the Crossrail scheme. Work will involve the construction of several auto-transformer stations and a feeder station site at Pudding Mill Lane to provide a 25 kV supply to the overhead line equipment that will power the new Crossrail trains.
Costain is also constructing for National Grid the new cable tunnels to provide power to the other Crossrail feeder station at Kensal Green. Costain’s other Crossrail projects include Bond Street and Paddington stations and works at Eleanor Street and Mile End Park.
When Crossrail opens in 2018, it will transport an estimated 200 million people each year.
