Commuters can now enjoy unlimited free Wi-Fi at Eastbourne Railway Station.
The service, provided by O2, is also available at Polegate.
Charles Horton, CEO of Govia Thameslink Railway which runs the four routes, said, "There’s no advertising and no catch – just free unlimited Wi-Fi for whoever logs on at 105 of our stations. Passengers can use our On Track app to see the progress of their trains, plan journeys and even book a ticket. They’ll be able to Facebook their friends, tweet and check emails – everything that’s possible in the connected world."
