+Travel::Status::DE::EFA::Departure - Information about a single
+departure received by Travel::Status::DE::EFA
+
+=head1 SYNOPSIS
+
+ for my $departure ($status->results) {
+ printf(
+ "At %s: %s to %s from platform %d\n",
+ $departure->datetime->strftime('%H:%M'), $departure->line,

+
+version 2.02
+
+=head1 DESCRIPTION
+
+Travel::Status::DE::EFA::Departure describes a single departure as obtained by
+Travel::Status::DE::EFA. It contains information about the time, platform,
+line number and destination.
+
+=head1 METHODS
+
+=head2 ACCESSORS
+
+=over
+
+=item $departure->countdown
+
+Time in minutes from now until the tram/bus/train will depart, including
+realtime data if available.
+
+If delay information is available, it is already included.
+
+=item $departure->datetime
+
+DateTime(3pm) object for departure date and time. Realtime data if available,
+schedule data otherwise.
+
+=item $departure->delay
+
+Expected delay from scheduled departure time in minutes. A delay of 0
+indicates departure on time. undef when no realtime information is available.
+
+=item $departure->destination
+
+Destination name.
+
+=item $departure->hints
+
+Additional information related to the departure (list of strings). If
+departures for an address were requested, this is the stop name, otherwise it
+may be recent news related to the line's schedule.
+
+=item $departure->is_cancelled
+
+1 if the departure got cancelled, 0 otherwise.
+
+=item $departure->key
+
+Unknown. Unlike the name may suggest, this is not a unique key / UUID for a
+departure: On the same day, different lines departing at the same station
+may have the same key. It might, however, be unique when combined with the
+B<line> information.
+
+=item $departure->line
+
+The name/number of the line.
+
+=item $departure->lineref
+
+Travel::Status::DE::EFA::Line(3pm) object describing the departing line in
+detail.
+
+=item $departure->mot
+
+Returns the "mode of transport" number. This is usually an integer between 0
+and 11.
+
+=item $departure->mot_name
+
+Returns the "mode of transport", for instance "zug", "s-bahn", "tram" or
+"sonstige".
+
+=item $departure->occupancy
+
+Returns expected occupancy, if available, undef otherwise.
+
+Occupancy values are passed from the backend as-is. Known values are
+"MANY_SEATS" (low occupation), "FEW_SEATS" (high occupation),
+"STANDING_ONLY" (very high occupation), and "FULL" (boarding not advised).
+
+=item $departure->origin
+
+Origin name.
+
+=item $departure->platform
+
+Departure platform number (may not be a number).
+
+=item $departure->platform_db
+
+true if the platform number is operated by DB ("Gleis x"), false ("Bstg. x")
+otherwise.
+
+Unfortunately, there is no distinction between tram and bus platforms yet,
+which may also have the same numbers.
+
+=item $departure->route_interesting
+
+List of up to three "interesting" stations served by this departure. Is a
+subset of B<route_post>. Each station is a Travel::Status::DE::EFA::Stop(3pm)
+object.
+
+=item $departure->route_pre
+
+List of stations the vehicle passed (or will have passed) before this stop.
+Each station is a Travel::Status::DE::EFA::Stop(3pm) object.
+
+=item $departure->route_post
+
+List of stations the vehicle will pass after this stop.
+Each station is a Travel::Status::DE::EFA::Stop(3pm) object.
+
+=item $departure->rt_datetime
+
+DateTime(3pm) object holding the departure date and time according to
+realtime data. Undef if unknown / unavailable.
+
+=item $departure->sched_datetime
+
+DateTime(3pm) object holding the scheduled departure date and time.
+
+=item $departure->train_type
+
+Train type, e.g. "ICE". Typically only defined for long-distance trains.
+
+=item $departure->train_name
+
+Train name, e.g. "ICE International" or "InterCityExpresS" or "Deichgraf".
+Typically only defined for long-distance trains.
+
+=item $departure->train_no
+
+Train number. Only defined if departure is a train.
+
+=item $departure->type
+
+Type of the departure. Note that efa.vrr.de sometimes puts bogus data in this
+field. See L</DEPARTURE TYPES>.
+
+=back
+
+=head2 INTERNAL
+
+=over
+
+=item $departure = Travel::Status::DE::EFA::Departure->new(I<%data>)
+
+Returns a new Travel::Status::DE::EFA::Departure object. You should not need to
+call this.
+
+=item $departure->TO_JSON
+
+Allows the object data to be serialized to JSON.
