Stations which are also stops for local or long distance trains have no stationID.

Stations like “Hauptbahnhof“ or “Wahren“ can be queried and are found by a stations query but the id is null. Therefore these stations can’t be used in a departures query since they also return multiple results when a stations query is used.

Is there another way to get departures for those stations?

Just realized this has been unanswered since more than 2 years, really sorry about that 😄. Please re-open if you're still interested in an answer.
