I have the following question regarding the happy weekend ticket which I intend to use during my trip to Cologne in July 2014 for the Rhine valley cruise. I will be based in Cologne and, after researching this site, I decided to travel by train to Bingen, then by boat to St. Goar. Afterwards I will return by train to Cologne and make several stops along the way ( Oberwesel, Bacharach).
On the DB Bahn web site I have found that "The Schönes-Wochenende-Ticket is valid on: All local rail services from DB AG (S-Bahn, RB, IRE, RE) on services offered by many transport associations and on non-federal railways.......".
On the DB Bahn timetable Cologne to Bingen (Rhein) Hbf, when choosing "only local transport" I have found at "Products" the following train types: MRB (Mittelrheinbahn (trans regio), RE, or a combination of both.
So is the MRB train covered by the Happy Weekend ticket? The DB Bahn web site refers only to S-Bahn, RB, IRE, RE. Thank you!
