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 capital.
As design partner, the company will work collaboratively 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. This will ensure that train drivers of both the 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, the team will use automated tools and standardised processes to enhance accuracy, effectiveness and productivity.
Clarke added: “We will draw on our in-house design capability and experience of delivering complex projects to help streamline the delivery phase of the works - proactively seeking opportunities to drive efficiencies and save time and money, without compromising safety.”
Costain will also provide technical assurance services during the delivery phase of the project, collaborating with the client and construction partner to ensure the effective delivery of the signalling upgrades.
