+=head1 NAME
+
+Travel::Status::DE::DeutscheBahn::Result - Information about a single
+arrival/departure received by Travel::Status::DE::DeutscheBahn
+
+=head1 SYNOPSIS
+
+ for my $departure ($status->results) {
+ printf(
+ "At %s: %s to %s from platform %s\n",
+ $departure->time,
+ $departure->line,
+ $departure->destination,

+ );

+
+ # or (depending on module setup)
+ for my $arrival ($status->results) {

+ $arrival->time,
+ $arrival->line,
+ $arrival->origin,
+ $arrival->platform,
+ );
+ }
+
+=head1 VERSION
+
+version 1.02
+
+=head1 DESCRIPTION
+
+Travel::Status::DE::DeutscheBahn::Result describes a single arrival/departure
+as obtained by Travel::Status::DE::DeutscheBahn. 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->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<max>])
+
+Returns a list of up to I<max> (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<route>, but still present in
+B<route_raw>.
+
+=item $result->route_timetable
+
+Similar to B<route>. 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.
+
+=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<data>:
