Do not trust Trainline! Neither the UK nor the EU branch is any good, and they go to considerable lengths to avoid enabling you to contact the EU branch in particular (it's email only, with a response "in 2 days"!). If anything goes wrong with your journey (a delayed train meaning you miss your connection, for instance), they will deny all responsibility for arranging replacement journeys, even though they're the ones who have taken your money. My specific case: travelling via 4 trains from Halle (Germany) to London, with the first train delayed by 25 minutes, meaning I missed all my connections, including the Eurostar. DeutscheBahn was very good (despite the delay, for which they're now notorious): they issued me with replacement tickets on different trains to get me as far as Brussels for my Eurostar. Of course, I still missed the Eurostar connection, but was advised by Eurostar, DeutscheBahn and Trainline UK to contact the Trainline EU office (by email!). Their response? "It's not our fault you've missed the Eurostar: DeutscheBahn have to refund you because they caused the delay." No acknowledgement of the fact that Trainline were the ones who took the money. This was the first time I used their "service", and it will be the last.
