The firm has signed an Early Contractor Involvement deal through Pagabo’s civil engineering and infrastructure framework.

Paul Lilley, Divisional Director, Rail and Depots said: “We are delighted to be starting our first contract procured through Pagabo’s civil engineering and infrastructure framework by offering support to essential upgrades to the Piccadilly line’s Cockfosters Depot.

“Our collaboration with Pagabo, TfL, and our supply chain partners will be crucial for the successful and safe execution of this project. We look forward to sustainably modernising the Piccadilly line, ensuring it is fit for future use.”

As part of the upgrade, TfL is introducing a fleet of 94 new walk-through, air-conditioned trains on the Piccadilly line.
