Acela Express trains are now offering free wireless internet service, Amtrak announced today. The service, dubbed AmtrakConnect, is in place on all 20 high-speed Acela trains, in addition to the six major stations along the Northeast Corridor (Union Station, Baltimore Penn Station, Philadelphia 30th Street Station, New York Penn Station, Providence Station and Route 128 Station in Boston), and in ClubAcela lounges. Both Business and First class passengers will be able to use the service on Acela. Officials say AmtrakConnect will remain free of charge “during the introductory period, after which the policy will be reviewed based on customer demand and system performance.”
