More London Underground tunnels get mobile coverage as rollout expands

Mobile phone coverage on the London Underground is expanding, with more sections of the Piccadilly, Northern, and Victoria lines being switched on recently.

Mobile coverage has been expanded along the Northern line with the tunnelled section between Balham and South Wimbledon recently getting mobile coverage, as well as Kennington, Oval, Tooting Broadway and South Wimbledon stations.

Work is now underway to extend coverage in the tunnels down to Morden and up to Kennington by the end of summer. The Bank branch of the Northern line between Euston and Bank is also receiving coverage for the first time.

It has taken longer than originally planned to extend the coverage on the Northern line as additional assurance work was required to ensure equipment installations were compliant, which delayed some of the work.

On the Victoria line, coverage is now being rolled out between Vauxhall and Pimlico. This follows the extension of coverage on the Piccadilly line and Victoria line to King’s Cross St Pancras earlier this year, and the Elizabeth line achieving full 4G mobile coverage last year.

More stations and tunnels are expected to go live in the coming months, including King’s Cross St Pancras, Green Park and further sections of the Victoria line.

All four mobile network operators – Three UK, EE, Vodafone, and Virgin Media O2 (VMO2) – are taking part in the rollout, which Boldyn Networks is deploying at no cost to TfL.

In the coming months, mobile coverage will be expanded along the Jubilee line, starting at Swiss Cottage and progressing along the line to link with existing coverage at Westminster. Major interchange stations such as Green Park and King’s Cross St Pancras, as well as further sections of the Victoria line from Green Park to Brixton, will also start to get mobile coverage for the first time.

Testing was recently completed to ensure that the introduction of mobile coverage wouldn’t impact the operation of the Tube network on the sub-service lines, meaning that coverage can start to be introduced to these lines later this year.

The Deputy Mayor for Transport, Seb Dance, said: “The introduction of 4G and 5G along further stretches of the Northern, Piccadilly and Victoria line means even more Londoners will now be able to stay connected on the Underground, reading, streaming or catching up with loved ones. This is yet another step towards delivering the Mayor’s commitment to rolling out 4G and 5G across the whole Tube network, building a better London for everyone.”

The expanding coverage will also give TfL staff better connectivity to pass on information to support the safe and reliable running of the network. It will also host the new Emergency Services Network (ESN) which, when fully operational, will be able to give first responders immediate access to data, images and information in live situations and emergencies on the frontline.

Work to deliver mobile coverage across the whole Tube network will continue throughout 2025 and 2026 to fully introduce coverage within stations and tunnels.

The work in 2026 will primarily focus on sections outside Central London, including the Circle and District lines, where several stations already have limited mobile coverage due to their proximity to the surface, as well as smaller tunnelled sections that require individual treatment.
