It contains information about the platform, time, route and more. =head1 METHODS =head2 ACCESSORS =over =item $result->date Arrival/Departure date in "dd.mm.yyyy" format. =item $result->delay Returns the train's delay in minutes, or undef if it is unknown. =item $result->info Returns additional information, for instance the reason why the train is delayed. May be an empty string if no (useful) information is available. =item $result->is_cancelled True if the train was cancelled, false otherwise. =item $result->line =item $result->train Returns the line name, either in a format like "S 1" (S-Bahn line 1) or "RE 10111" (RegionalExpress train 10111, no line information). =item $result->platform Returns the platform from which the train will depart / at which it will arrive. =item $result->route Returns a list of station names the train will pass between the selected station and its origin/destination. =item $result->route_end Returns the last element of the route. Depending on how you set up Travel::Status::DE::DeutscheBahn (arrival or departure listing), this is either the train's destination or its origin station. =item $result->destination =item $result->origin Convenience aliases for $result->route_end. =item $result->route_interesting([I]) Returns a list of up to I (default: 3) interesting stations the train will pass on its journey. Since deciding whether a station is interesting or not is somewhat tricky, this feature should be considered experimental. The first element of the list is always the train's next stop. The following elements contain as many main stations as possible, but there may also be smaller stations if not enough main stations are available. In future versions, other factors may be taken into account as well. For example, right now airport stations are usually not included in this list, although they should be. Note that all main stations will be stripped of their "Hbf" suffix. =item $result->route_raw Returns the raw string used to create the route array. Note that canceled stops are filtered from B, but still present in B. =item $result->route_timetable Similar to B. however, this function returns a list of array references of the form C<< [ arrival time, station name ] >>. =item $result->time Returns the arrival/departure time as string in "hh:mm" format. =item $result->type Returns the type of this train, e.g. "S" for S-Bahn, "RE" for Regional Express or "ICE" for InterCity-Express. =back =head2 INTERNAL =over =item $result = Travel::Status::DE::DeutscheBahn::Result->new(I<%data>) Returns a new Travel::Status::DE::DeutscheBahn::Result object. You usually do not need to call this. Required I: =over =item B
