Costain to upgrade London Underground signalling infrastructure

Transport for London (TfL) has appointed Costain to design critical upgrades to the Piccadilly line’s signalling infrastructure.

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 set to enter service in 2025.

As part of the commission, which came through TfL’s Professional Services Framework, the British construction and engineering company 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 company said in a press release.

The surveys will include ecological, environmental, ground condition and contamination, structural integrity, buried services (utilities), line level, and track clearance assessments.

Andy Clarke, director for integrated transport at Costain, said: “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.”

During the design phase, Costain will use automated tools and standardised processes to enhance accuracy, effectiveness, and productivity.
