Wifi to be installed at every SE1 tube station before Olympics

Borough, Elephant & Castle, Lambeth North, London Bridge, Southwark and Waterloo are among the first 80 London Underground Stations to be fitted with wifi equipment as part of a deal with Virgin Media.

Access to the service will be free during the summer; pricing has not yet been announced for the autumn and beyond.

"Our customers will soon be able to connect to the internet for live travel information while they are on the move through stations," says Gareth Powell, London Underground's director of strategy and service development.

"Bringing a next generation wifi service to one of the world's oldest underground transport networks is progressing as planned and the forthcoming service is testing well.

"The first stations include some of our busiest and most well-known destinations and we're on-track for a successful launch this summer – all delivered at no additional cost to fare payers or taxpayers."

Caroline Pidgeon AM, leader of the Lib Dem group on the London Assembly, has called on City Hall to clarify the future costs of the service.

"Provision of wifi at a few London Underground stations this summer is welcome, but the key issue is how long it will actually be free for most passengers," she said.

"It is time the Mayor provided far more information about the commercial deal that he has entered into with Virgin Media."
