I see there is a boat that goes from Dresden to Rathen. The company is Sachsischer dampfschhiffahrt. I don't know if there are other companies or not. Does anyone know if it's possible to get off at Bad Schandau and take the train from there to Prague? I know that there is such a train but don't know if the boat docks there to let people disembark or just cruises past. would the train station be within walking distance of the dock?
