It contains information about the platform, time, route and more. =head1 METHODS =head2 ACCESSORS =over =item $result->additional_stops Returns served stops which are not part of the schedule. I.e., this is the set of actual stops (B) minus the set of scheduled stops (B). =item $result->arrival DateTime(3pm) object for the arrival date and time. undef if the train starts here. Contains realtime data if available. =item $result->arrival_delay Estimated arrival delay in minutes (integer number). undef if no realtime data is available, the train starts at the specified station, or there is no scheduled arrival time (e.g. due to diversions). May be negative. =item $result->arrival_is_additional True if the arrival at this stop is an additional (unscheduled) event, i.e., if the train started its journey earlier than planned. =item $result->arrival_is_cancelled True if the arrival at this stop has been cancelled. =item $result->arrival_wings Returns a list of references to Travel::Status::DE::IRIS::Result(3pm) objects which are coupled to this train on arrival. Returns nothing (false / empty list) otherwise. =item $result->canceled_stops Returns stops which are scheduled, but will not be served by this train. I.e., this is the set of scheduled stops (B) minus the set of actual stops (B). =item $result->classes List of characters indicating the class(es) of this train, may be empty. This is slighty related to B, but more generic. At this time, the following classes are known: D Non-DB train. Usually local transport D,F Non-DB train, long distance transport F "Fernverkehr", long-distance transport N "Nahverkehr", local and regional transport S S-Bahn, rather slow local/regional transport =item $result->date Scheduled departure date if available, arrival date otherwise (e.g. if the train ends here). String in dd.mm.YYYY format. Does not contain realtime data. =item $result->datetime DateTime(3pm) object for departure if available, arrival otherwise. Does not contain realtime data. =item $result->delay Estimated delay in minutes (integer number). Defaults to the departure delay, except for trains which terminate at the specifed station. Similar to C<< $result->departure_delay // $result->arrival_delay >>. undef if no realtime data is available. May be negative. =item $result->delay_messages Get all delay messages entered for this train. Returns a list of [datetime, string] listrefs sorted by newest first. The datetime part is a DateTime(3pm) object corresponding to the point in time when the message was entered, the string is the message. If a delay reason was entered more than once, only its most recent record will be returned. =item $result->departure DateTime(3pm) object for the departure date and time. undef if the train ends here. Contains realtime data if available. =item $result->departure_delay Estimated departure delay in minutes (integer number). undef if no realtime data is available, the train terminates at the specified station, or there is no scheduled departure time (e.g. due to diversions). May be negative. =item $result->departure_is_additional True if the train's departure at this stop is unscheduled (additional), i.e., the route has been extended past its scheduled terminal stop. =item $result->departure_is_cancelled True if the train's departure at this stop has been cancelled, i.e., the train terminates here and does not continue its scheduled journey. =item $result->departure_wings Returns a list of references to Travel::Status::DE::IRIS::Result(3pm) objects which are coupled to this train on departure. Returns nothing (false / empty list) otherwise. =item $result->destination Alias for route_end. =item $result->info List of information strings. Contains both reasons for delays (which may or may not be up-to-date) and generic information such as missing carriages or broken toilets. =item $result->is_additional True if the train's arrival and departure at the stop are unscheduled additional stops, false otherwise. =item $result->is_cancelled True if the train was cancelled, false otherwise. Note that this does not contain information about replacement trains or route diversions. =item $result->is_transfer True if the train changes its ID at the current station, false otherwise. An ID change means: There are two results in the system (e.g. RE 10228 MEnster -> Duisburg, RE 30028 Duisburg -> DEsseldorf), but they are the same train (RE line 2 from MEnster to DEsseldorf in this case) and should be treated as such. In this case, Travel::Status::DE::IRIS merges the results and indicates it by setting B to a true value. In case of a transfer, B and B are set to the "new" value, the old ones are available in B and B. =item $result->is_unscheduled True if the train does not appear in the requested plans. This can happen because of two reasons: Either the scheduled time and the actual time are so far apart that it should've arrived/departed long ago, or it really is an unscheduled train. In that case, it can be a replacement or an additional train. There is no logic to distinguish these cases yet. =item $result->is_wing Returns true if this result is a wing, false otherwise. A wing is a train which has its own ID and destination, but is currently coupled to another train and shares all or some of its route. =item $result->line Train type with line (such as C<< S 1 >>) if available, type with number (suc as C<< RE 10126 >>) otherwise. =item $result->line_no Number of the line, undef if unknown. Seems to be set only for S-Bahn and regional trains. Note that some regional and most long-distance trains do not have this field set, even if they have a common line number. Example: For the line C<< S 1 >>, line_no will return C<< 1 >>. =item $result->messages Get all qos and delay messages ever entered for this train. Returns a list of [datetime, string] listrefs sorted by newest first. The datetime part is a DateTime(3pm) object corresponding to the point in time when the message was entered, the string is the message. Note that neither duplicates nor superseded messages are filtered from this list. =item $result->old_train_id Numeric ID of the pre-transfer train. Seems to be unique for a year and trackable across stations. Only defined if a transfer took place, see also B. =item $result->old_train_no Number of the pre-tarnsfer train, unique per day. E.g. C<< 2225 >> for C<< IC 2225 >>. See also B. Only defined if a transfer took place, see also B. =item $result->origin Alias for route_start. =item $result->qos_messages Get all current qos messages for this train. Returns a list of [datetime, string] listrefs sorted by newest first. The datetime part is a DateTime(3pm) object corresponding to the point in time when the message was entered, the string is the message. Contains neither superseded messages nor duplicates (in case of a duplicate, only the most recent message is present) =item $result->platform Arrival/departure platform as string, undef if unknown. Note that this is not neccessarily a number, platform sections may be included (e.g. C<< 3a/b >>). =item $result->raw_id Raw ID of the departure, e.g. C<< -4642102742373784975-1401031322-6 >>. The first part appears to be this train's UUID (can be tracked across multiple stations), the second the YYmmddHHMM departure timestamp at its start station, and the third the count of this station in the train's schedule (in this case, it's the sixth from thestart station). About half of all departure IDs do not contain the leading minus (C<< - >>) seen in this example. The reason for this is unknown. This is a developer option. It may be removed without prior warning. =item $result->realtime_xml XML::LibXML::Node(3pm) object containing all realtime data. undef if none is available. This is a developer option. It may be removed without prior warning. =item $result->replaced_by Returns a list of references to Travel::Status::DE::IRIS::Result(3pm) objects which replace the (usually cancelled) arrival/departure of this train.
