+Sometimes, Deutsche Bahn splits up major stations in their IRIS interface.
+For instance, "KE<ouml>ln Messe/Deutz" actually consists of
+"KE<ouml>ln Messe/Deutz" (KKDZ), "KE<ouml>ln Messe/Deutz Gl. 9-10"
+(KKDZB) and "KE<ouml>ln Messe/Deutz (tief)" (KKDT).
+
+By default, B<db-iris> will show departures for all of these stations when

+station part specified on the commandline are shown.
