This contract is the second ‘batch’ awarded that, when completed, will provide the infrastructure to support the introduction of the new ‘24 Tube Stock’ (24TS) and increase the peak Piccadilly line service to 27 trains per hour. The works will also provide upgrades to support the resilience of the Northern line.

The work involves substation upgrades at multiple locations in addition to high voltage equipment upgrades, extensions and modifications. Locations where the upgrades will be implemented include Neasden, Acton Town and Ravenscourt Park.

Works began on 25 March, following the signing of the contract, and are due to be completed in 2027.

With the contract announcement, we will continue our longstanding partnership on the London Underground. We previously won a £40million Piccadilly line contract in June 2022 and have worked on several initiatives, including a major redevelopment at Liverpool Street as part of the Crossrail project, and 16 substation upgrades along the Metropolitan, Circle, Hammersmith & City, and District lines.
