Talks between TfL, the London mayor and telecoms groups will reportedly begin after next week's general election

Tube users could soon get phone signal underground, it’s been reported.

TfL is said to be in talks with telecommunications groups, and could offer full mobile coverage on London Underground after next week’s general election.  

Commuters can already access the internet on sections of the tube network by connecting to Virgin Media’s Wi-Fi service, but it isn’t especially practical.

It requires users to register their details and is only available on platforms and not tunnels, meaning tube users can only connect to it when they pull up at a station, before quickly being kicked off again when their train starts moving.

The Financial Times says Transport for London (TfL) and London mayor Sadiq Khan are preparing to invite bids for telecoms groups.

According to the paper, three people familiar with the plans said a “number of companies were vying for the work”.

“We are keen to offer mobile phone coverage for our customers. The introduction of this would need to be commercially viable and would follow engagement with staff and customers,” a TfL spokesman told the FT.

The introduction of a 4G network on the Underground would unlock a number of benefits for users. 

It would enable users to make uninterrupted phone calls underground, as well as browse the web, use apps, stream TV shows, sports fixtures and films, and even complete work. 

It should also make it much easier to find anyone you happen to lose in an underground station.

Other major cities including Paris, New York and Tokyo already have the technology to prevent mobile blackspots while on their metro systems.
