Virgin Media has switched on wireless broadband services at another 20 stations on the London Underground network, it has been announced.
Camden Town, Clapham Common, Notting Hill Gate and Russell Square are among the terminals to gain Wi-Fi connectivity, as the broadband provider brings the number of enabled stations to 92.
A further 28 are scheduled to come online during early 2013, taking the total to 120.
Some 800,000 people have already registered with Virgin Media Wi-Fi, launched as a free service for 2012, allowing them to stay up-to-date with TfL travel information.
The service also enables them to Tweet, access apps, update Facebook and send emails whilst underground.
Virgin Media recently announced EE and Vodafone as wholesale partners for its Wi-Fi service, meaning the firms' customers will be able to enjoy broadband access across the Tube.
The broadband provider will also launch a pay-as-you-go (PAYG) service in the new year, offering daily, weekly and monthly passes to commuters and tourists.
Jon James, Executive Director of Broadband at Virgin Media, said Wi-Fi on the London Underground has been "an incredible success".
"We’ve rolled out the service to reach even more stations throughout London, from Camden Town to Clapham Common," he stated.
"Our wholesale agreement with EE and Vodafone will keep the majority of Tube users connected for no extra cost and every Londoner and visitor can choose from affordable PAYG options with free, up-to-the-minute travel, news and entertainment for everyone.”
Gareth Powell, Director of Strategy and Service Development for London Underground, said thousands of rail users are taking advantage of Wi-Fi at Tube stations to keep up-to-date with live travel information, news and entertainment.
"The arrival of Wi-Fi at these extra 20 stations will allow even more of our passengers to connect to the net while they are on the move across London," he stated.
