The ATC joint venture, consisting of Alstom
, TSO and Costain, was awarded its first contract to fit out and commission the Crossrail tunnels currently being bored under the streets of London
The contract is worth approximately $4.4 million and one of the largest that Crossrail intends to award. It will see the Alstom-led joint venture fitting out the approximately 13 miles of twin tunnels that will stretch under London with the track and power equipment necessary for Crossrail trains to operate from 2018.
ATC will be installing more than 24 miles of track, together with rigid overhead conductors, a system that is being used for the first time in the UK to power heavy mainline trains through tunnels.
