New Signalling Will Boost The District Line

Testing shows that local tube trains can run closer together

More frequent and reliable services are coming soon to the District Line, following the latest weekend of testing on a new signalling system.

Transport for London (TfL) says the system is set to transform the District Line as well as the Circle, Hammersmith & City and Metropolitan lines, and that more trains were run between Hammersmith and Edgware Road last weekend than in any previous test.

TfL says this represents another step towards the launch of the new system this summer.

The new system, provided by electrical engineering company Thales, will improve reliability and boost capacity on 40% of the Tube network and has undergone significant testing since October.

It will also transform one of the oldest parts of the Tube network into one of the most modern.

The section between Hammersmith and Edgware Road will be the first to go live on the new system, which will provide better, more accurate real-time customer information and improve reliability.

The new system will be introduced progressively over 14 sections across the network, each one improving reliability as it is introduced. Customers will benefit from quicker, more frequent services from 2021, with all four lines using the new system by 2023.

The new modern signalling will allow trains to run closer together, which will increase the frequency of train services across these lines with 32 trains per hour set to operate in the central London section. This will boost capacity by a third across all four lines – equivalent to space for an extra 36,500 customers during the busiest times of day.

Stuart Harvey, TfL’s Director of Major Projects, says, "We are investing billions of pounds to make real improvement for customers including making journeys quicker and less crowded. The team are working around the clock so that customers can start to experience some of the benefits from this summer."

The Four Lines Modernisation project will finish in 2023, when all four lines are operating under the new Thales system. Services will begin to increase in frequency from 2021, when the central London section of the network has been modernised.
