Transport for London (TfL) has tested a new signalling system from Hammersmith to Euston Square and Paddington, including the Baker Street junction of London Underground.

The implementation of the new Thales communications-based train control (CBTC) system is expected to improve reliability of the operations and provide more accurate real-time customer information.

Scheduled to be implemented on the Circle, District, Hammersmith & City and Metropolitan lines, the new system will go live initially on the section between Hammersmith and Edgware Road this year.

“This project will make an enormous difference to the journeys of tens of thousands of Londoners.”

The latest testing was conducted from a control room at Hammersmith Service Control Centre, which is also set to begin operations this year.

London Underground managing director Mark Wild said: “It’s great news that we have been able to start testing on the next section of the network. It shows that our Four Lines Modernisation Project is now moving at pace and our customers will be able to see the benefits of this huge programme soon.

“This project will make an enormous difference to the journeys of tens of thousands of Londoners and will help us to deliver the Mayor’s vision for a greener, healthier city by making those journeys quicker and boosting capacity.”

The new system will be gradually introduced over 14 sections across the Tube network.

All four lines are slated to use this signalling system by 2023, while customers are expected to witness quicker and more frequent services from 2021.

32 trains are estimated to arrive per hour in the central London section, thereby improving the overall capacity across all four lines by a third.

TfL is scheduled to carry out further testing of the system in the coming months. The next stage of testing will feature eight-car S-stock trains used on the Metropolitan line.
