WiFi on the train

This is outstanding; got on the train home from Falmer to Seaford, booted up my PowerBook and it found a WiFi signal, quite strong, all the way home. At first I couldn't believe it at first so I started up MacStumbler which confirmed it. The network was called Nomad and it seems they're putting WiFi into trains. I couldn't connect to it, but I'm sure that can be resolved. Now there will be no need for me to get off the train, I can simply stay on it all day and work away as I shuttle between Seaford and Falmer, except when they close down the track. Seems this is old hat, as the press releases on the Nomad site are dated last year, but I've been travelling on trains daily with a WiFi-enabled computer since long before that, and this is the first time I've got a signal
