High-speed mobile coverage across the Tube expected by year-end

Transport for London says more Tube stations and tunnel sections now have high-speed mobile coverage, including the whole Elizabeth line; TfL expects most of the Northern and Metropolitan lines to have tunnel coverage by the end of summer 2026.

Transport for London says more stations and sections of the Tube network now have high-speed mobile coverage, and the rollout is continuing across the network. The announcement notes the first sections of the Circle and District lines are included, and the entire Elizabeth line already has coverage. Several specific stations are listed as covered now, with others due to go live in the coming months. TfL also said the project will support the new Emergency Services Network when that system is fully operational. Key details: - The entire Elizabeth line is reported as covered, and stations such as Euston Square, Cannon Street and Battersea Power Station are included. - The first sections of the Circle and District lines now have high-speed mobile coverage, according to TfL. - King's Cross St Pancras, Gloucester Road, Warwick Avenue and Vauxhall are due to go live in the next few months. - TfL said it expects the vast majority of the Northern and Metropolitan lines to have coverage in tunnels by the end of summer 2026. - The rollout will host the new Emergency Services Network, which is reported to provide first responders with immediate access to data when operational. - About 400 engineers are regularly working on the project overnight, and installation work will continue through 2026, including sections outside central London and short tunneled sections handled individually. Summary: The rollout increases mobile connectivity at stations and in tunnels across parts of the Tube and is presented as supporting operational and emergency data use. Work will continue through 2026 with additional stations coming online in the next few months and broader tunnel coverage expected by the end of summer 2026.
