 Show the entire route of all trains (both before and after I<station>).
 
+=item B<-m>, B<--mot> I<motlist>
+
+Comma-separated list of modes of transport to filter by. Using this option
+causes all arrivals/departures whose mot not in I<motlist> to be discarded.
+
+The mot is based on the train type and accepts a superset of the following
+values:
+
+    local transport:
+    IR   Inter-Regio (rare in Germany, mostly used in Switzerland)
+    IRE  Inter-Regio Express (rare)
+    RB   Regionalbahn (slower than RE)

+    EC   Eurocity
+    IC   Intercity
+    ICE  Intercity-Express
+    THA  Thalys
+
+Depending on the city and country, other types may be used as well. Examples
+include "ABR" / "NWB" (private trains included in the local transport tariff
+system), "HKX" (private train not included in any DB tariffs) and
