Oops sorry that's the NTL solution!
I would imagine they'll install Wireless Access Points in each carridge that'll feed back to a central hub/router which in turn will be connected via ???? to the outside world.
Any suggestion on what the ???? - I assume they couldn't run it through the tracks (always breaking!) so the only other perm connection is the power lines unless they do use satelite (interesting doing your banking on the train as you enter a tunnel - Unless my 1st suggestion works!)

One of my old school pals and EX-business partners is the Technical Director at the Company MyZones (WiFi)
Ken worked for Alcatel and I was contracted to Alcatel installing IT/Satellite navigation equipment for Road transport systems.
It is entirely feasilbe that the Carrier is actually Sattelite based but WiFI only in the carraige.
