Costain has been appointed by Transport for London (TfL) to design critical upgrades to the signalling infrastructure on the Piccadilly line to improve passenger journeys across the UK capital.
Costain will work with TfL’s design team to ensure that the signalling system in West London between Heathrow Airport and Baron’s Court is compatible with both the existing London Underground trains and the new fleet of 24TS passenger trains, which will enter service in 2025.
Andy Clarke, director for integrated transport at Costain, said: “The customer is at the heart of everything we do. We are committed to playing our part in modernising operations to enable more reliable, more frequent and faster journeys for passengers.”
As part of the commission, which came through TfL’s Professional Services Framework, Costain will conduct a series of surveys to inform the design process for around 200 existing signals to ensure drivers of both current and new trains know when they can safely proceed.
The surveys will include ecological, environmental, ground condition and contamination, structural integrity, buried services (utilities), line level and track clearance assessments. During the design phase, Costain will use automated tools and standardised processes to enhance accuracy, effectiveness and productivity.
Costain will also provide technical assurance services during the delivery phase of the project.
