I've been searching for a European train app for (mostly) research and planning purposes. Until now, iRail was the best. In my tests, Trainline provides most (not all) of your train route options, but it does provide the fastest routes. I mean, why choose the one option which takes an hour longer? While I tend to want to make the most informed decision and know all my options, the truth is, I would never take the least efficient option, so Trainline EU is my new go-to train app.. Another plus: a great help section! I like that they provide known strike information and user recourse.
