Is wifi free on trains?

I'm going up to Paddington on the Penzance Paddington train. Is there free wifi on this train? If not, how much does it cost? Thanks 🙂 also where do I get it? Do I get it from the buffet car and get the code then pay from my card once I've set it up or can I pay in cash up front? Thanks

No trains have 'free Wi-Fi'. On Virgin and Cross Country Services, Wi-Fi is available but it is expensive to pay for. I would recommend a dongle or something alike as the Wi-FI on trains is slow in most areas and there is not a lot of content you can access.

As far as I am aware First Great Western's trains on this route do not have Wi Fi. You can telephone them and check 0345 7000 125
Christopher:
If the train has Wifi it is free – but not all trains have it yet. I believe the trial is on the Oxforfd and Worcester routes, not the Cornwall ones.

Not all have it yet, but there are just some that do.
