Transport for London (TfL) has appointed a programme support partner to review its plans for the renewal of signalling equipment across its four sub-surface lines.
A Mace and CPC Project Services (CPC) joint venture will support the delivery of a £760 million project to overlay CBTC signalling on the District, Circle, Metropolitan and Hammersmith & City lines.
The resignalling scheme has suffered a number of delays. The contract was re-let to Thales earlier this year after Bombardier, who had been contracted to do the work, decided it was unable to deliver the project.
Work will begin in 2021 with the Circle line and end with the Metropolitan line in 2023.
The overall cost of the modernisation programme, which includes new trains, has been set at £5.41 billion – more than the original £4.26 billion quoted but less than a revised figure given in March.
So the Circle Line is 1st to get the re-signalling then the District Line and Hammersmith & City Line and lastly the Metropolitan Line.
