=over

=item $result->date

=item $result->delay

Returns the delay in minutes, or undef if it is unknown.
Also returns undef if the arrival/departure has been cancelled.

Returns additional information, for instance the most recent delay reason.
undef if no (useful) information is available.

=item $result->is_cancelled

True if the arrival/departure was cancelled, false otherwise.

=item $result->is_changed_platform

True if the platform (as returned by the B<platform> accessor) is not the
scheduled one. Note that the scheduled platform is unknown in this case.

=item $result->messages

Returns a list of message strings related to this result. Messages usually are
service notices (e.g. "missing carriage") or detailed delay reasons

=item $result->platform

Returns the arrival/departure platform.
Realtime data if available, schedule data otherwise.

=item $result->route_end

=item $result->destination
