Commuters in Clapham will be able to stay connected underground as TfL rolls out 4G coverage across new sections of the Northern line.

The expansion includes the track between Clapham North and Balham, as well as Clapham Common and Clapham South stations.

Passengers will be able to browse the internet and make calls while traveling as TfL work towards mobile connectivity for the whole network.

It will also host the new Emergency Services Network which will give first responders immediate access to life saving information.
