London is slowly but surely making internet and signal blackouts on the tube a thing of the past. Over the past couple of years TfL has gradually been rolling out 4G and 5G coverage on the London Underground, with the Central, Northern, Jubilee, Piccadilly, Victoria and Bakerloo lines all now boasting sections with high-speed internet coverage.
Today (July 10) TfL has announced that even more of the tube now has 4G and 5G, thanks to developments on the Piccadilly, Northern and Victoria lines. The latest roll-out, which is being installed with Boldyn Networks, has focused mostly on south London.
On the Northern line, the tunnels between Balham and South Wimbledon now have data coverage, as do Kennington, Oval, Tooting Broadway and South Wimbledon stations. The line’s Bank branch between Euston and Bank is receiving coverage, and riders of the black tube line now have service all the way from South Wimbledon to Stockwell. By the end of the summer the tunnels between Kennington and Morden will also be connected.
On the Victoria, tunnels between Vauxhall and Pimlico now have high-speed internet, while King's Cross St Pancras and Green Park stations (both also on the Piccadilly) will soon get coverage. Tube tunnels between Green Park and Brixton are also getting 4G and 5G in the coming months.
Recent developments in the roll-out of internet coverage on the tube follow the news at the end of last year that the entire Elizabeth line – including tunnels and stations – now has 4G.
Commenting on the newly-covered stations, 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.’
Here’s a map of all the London tube stations and tunnels that now have 4G and 5G coverage.
