-Travel::Status::DE::HAFAS::Journey describes a single arrival/departure
-as obtained by Travel::Status::DE::HAFAS. It contains information about
-the platform, time, route and more.
+Travel::Status::DE::HAFAS::Journey describes a single journey. It is either
+a station-specific arrival/departure obtained by a stationboard query, or a
+train journey that does not belong to a specific station.
+
+stationboard-specific accessors are annotated with "(station only)" and return
+undef for non-station results.
