Reservations for regulars during construction in 2019
There will be some extensive construction work starting mid-2019 between Hamburg main station and Hamburg-Harburg, which have already been incorporated into the timetable. Please note the following information on seat reservations:
Since the seat reservation for holders of a subscription pass has been placed for the entire year, regulars may only make a free seat reservation on the route section from Cuxhaven to Hamburg-Harburg. However, your seat reservation is valid from/to Hamburg main station.
