- RP ticket from Cochem to Trier ($27), then two tagesticket delux zone 2 from Trier to Luxembourg (2x11,5) - can I catch any train or just regionals?
- Two "luxemburg spezial" (2x28):
bahn.de/regional/…luxemburg_spezial.shtml - can I catch any train or just regionals?
- something else
Both sites are in german, so I could not understand everything.
