=head1 NAME
db-wagenreihung - Interface to Deutsche Bahn carriage formation API
=head1 SYNOPSIS
B<db-wagenreihung> I<station> I<train-number>
=head1 VERSION
version 0.13
This is beta software: API and output format may change without notice.
=head1 DESCRIPTION
db-wagenreihung shows the carriage formation of train I<train-number> at
station I<station> (must be a name or DS100 code) as reported by the Deutsche
Bahn Wagenreihung API. As of April 2024, it has mature support for
long-distance (IC/EC/ICE) trains and a growing number of regional transport
providers that also offer mostly correct carriage formation data.
It is not possible to request the carriage formation at a train's terminus
station. This is a known limitation.
The departure of I<train-number> must be in the time range between now and
two hours in the future.
=head1 EXAMPLES
=over
=item db-wagenreihung 'Essen Hbf' 723
Show carriage formation of ICE 723 at Essen Hbf
=item db-wagenreihung TS 3259
Show carriage formation of IRE 3259 at Stuttgart Hbf
