So I purchased my DB ticket from Gengenbach to St. Goar (which is where I was originally planning on staying). Then I changed my hotel to Boppard, but decided not to change the train ticket since I could just add on a regional ticket from St. Goar to Boppard when I got there.
However, DB just sent me an email saying that my ticket for May 8th has changed, due to construction issues. The ticket now is as follows:
Lv. Gengenbach at 10:07
Arr Offenburg at 10:14
---transfer
Lv Offenburg 10:29
Arr Mannheim 11:24
---transfer
Lv Mannheim 11:52
Arr Mainz 12:43
---transfer
Lv Mainz 13:31
Arr Ingelheim 13:53
Lv Ingelheim 14:21 BY BUS
Arr St. Goar 15:00
The above adds one extra hour to my travel time and one extra transfer (plus a bus ride). Plus I still need to get to Boppard.
So the email from DB also says that because they have changed everything, I can change trains (originally I had the super saver non-changeable tickets). The exact language says:
Changes before you travel: Your ticket is no longer train-specific if
timetable changes are made before your journey starts, for example due
to construction work. If you originally bought a train-specific
ticket, this restriction does not apply in the following situations:If the timetable changes and the train is rescheduled to depart at an
earlier time. If the timetable change means your train arrives at your
transfer station with a delay of over 20 minutes. If a train/stop is
cancelled. If the connection is disrupted between your starting point
and transfer station. Instead, you can use your ticket on another
Deutsche Bahn service to reach the destination you booked.
So I checked and if I go from Gengenbach to Boppard, most of the ticketing would stay the same but instead of going from Mainz to Mannheim, I would take a train to Koblenz, arriving at 13:42, then leaving at 14:03 and arriving in Boppard at 14:14, 45 minutes earlier than I would arrive in St. Goar with the changed ticket. I realize that it's not the destination I booked, but I'm thinking that I could still tell them I can get to St. Goar faster even via Boppard (which I could). What do you all think?
