More sections of the Tube get 5G and 4G coverage

TfL aims to provide the entire network with mobile phone coverage

Mobile phone coverage has been expanded along more of the London Underground system, Transport for London (TfL) has announced.

Further sections of the Northern line and Victoria line have access to 4G and 5G.

TfL said more stations and tunnels are to go live in coming months, including King's Cross St Pancras, Green Park and more of the Victoria line.

The mayor of London originally promised passengers would have full mobile coverage across the network by 2024, but that was pushed back until at least 2026.

TfL said coverage has now been expanded along the Northern line including the tunnelled section between Balham and South Wimbledon, as well as Kennington, Oval, Tooting Broadway and South Wimbledon stations.

Passengers in south London travelling along the Northern line from South Wimbledon to Stockwell now have continuous coverage.

TfL said work is also underway to extend coverage in the tunnels down to Morden and up to Kennington by the end of the summer.

The Bank branch of the Northern line between Euston and Bank is also receiving coverage for the first time.

On the Victoria line, coverage is being rolled out between Vauxhall and Pimlico.

The Jubilee line's coverage is to be extended next, starting at Swiss Cottage and linking 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 high-speed mobile coverage for the first time in the next phase of work.
