=head1 DESCRIPTION

db-wagenreihung shows wagon orders as reported by the Deutsche Bahn Wagon Order

API. At the moment, only long-distance ICE trains operated by Deutsche

Bahn are supported. Most IC/EC lines also work, but results may not be

entirely correct.

db-wagenreihung shows the wagon order of train I<train-number> at station

I<station> (must be a name or DS100 code) as reported by the Deutsche Bahn

Wagon Order API. As of April 2020, long-distance IC/EC/ICFE trains are widely

supported, and some regions (e.g. Stuttgart/Karlsruhe) also provide wagon

orders for select regional trains. Data accuracy varies, but seems to be

improving over time.

It is not possible to request the wagon order 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.
