I don't recall ever being on a train where the WiFi worked. If I need internet access while on the train I just tether to my phone. This usually works fine until you're in rural areas or in a tunnel. I find Vodafone gives best coverage outside of cities and towns, 3 can be awesome if you get lucky. I once streamed a live F1 race while on the train from Edinburgh to London. There obviously were a few glitches but it really was good enough.
