Have found this page, which appears to be the answer,
http://wiki.openstreetmap.org/wiki/Proposed_features/shuttle_train

route=train_shuttle appears to be the answer until routers understand
relations. It certainly works for the  Niebüll-Westerland example listed
http://map.project-osrm.org/1iS

I could not find any in Switzerland that are mapped to link the roads to
the rails.
