The dream of a London Underground network that's totally Internet-connected is getting a step closer to reality, as BT announced that Charing Cross would be the first Tube station to have Wi-Fi access.

The service is due to start today and will be trialed for six months, allowing people to log on to the Internet from Charing Cross ticket hall area, as well as the Northern and Bakerloo line platforms. There won't be access in the actual trains, apart from a few seconds when the doors are open--or if your train is stuck.
