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. + +=back + +=head1 DEPARTURE TYPES + +The following are known so far: + +=over + +=item * Abellio-Zug + +=item * Bus + +=item * Eurocity + +=item * Intercity-Express + +=item * NE (NachtExpress / night bus) + +=item * Niederflurbus + +=item * R-Bahn (RE / RegionalExpress) + +=item * S-Bahn + +=item * SB (Schnellbus) + +=item * StraE<szlig>enbahn + +=item * U-Bahn + +=back + +=head1 DIAGNOSTICS + +None. + +=head1 DEPENDENCIES + +=over + +=item Class::Accessor(3pm) + +=back + +=head1 BUGS AND LIMITATIONS + +C<< $result->type >> may contain bogus data.
