The new annual timetable starts on 12 December. There was an app update today including the new timetable. It may still not be complete, however, because some operators are always very late with their new timetables.

Additionally, some operators will only publish their summer timetables sometime in May or early June.

Finally, you should only use the Interrail app as a last resort, for example if you’re not online. It doesn't get enough updates to be reliable.

Use the operators’ own websites and apps. For international planning, the DB website or DB Navigator app are a good choice.
