Costain, one of the UK’s leading tier one engineering solutions providers, has announced that ATC, its Joint Venture with Alstom and TSO, has been awarded a contract worth approximately £300m to design, fit-out and commission the railway systems in Crossrail’s tunnel network.

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.

Design work will commence immediately, with the fit-out works starting in 2014, and will be carried out within the entire tunnelled and surface sections of the Crossrail route between Royal Oak, Pudding Mill Lane and Plumstead Portals.

Costain has also announced that in Joint Venture with Alstom it has been awarded 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.

Crossrail will open in 2018. The Crossrail route will pass through 37 stations and will increase London's rail-based transport network capacity by 10 per cent. An estimated 200 million people will travel on Crossrail each year.
