Eurostar to trial Internet links over Wi-Fi on Chunnel trains: As part of an ongoing strategy of getting travelers who would normally fly from Paris to London or vice-versa to take the channel tunnel train, Eurostar is trialling the use of Wi-Fi in first class at no additional cost to passengers. The service uses satellite downlinks and cellular uplinks, as with most train trials. Service would be interrupted in the tunnel, but the majority of the trip will have active service.
This story has a few additional details and notes that trial service would begin by the end of 2004.
