I booked a journey from Brussels Midi to Essen in a couple of weeks' time. The tickets were booked through raileurope.com. Today I received an email from Deutsche Bahn telling me that due to a timetable change, the journey I was supposed to make can't be carried out as originally planned:
Fahrplanänderung auf Ihrer Reise nach Essen Hbf am 02. Okt. 2024: Fahrt nicht wie geplant möglich [Schedule change on your trip to Essen Hbf on 02 Oct 2024: Journey not possible as planned]
Guten Tag [my name],
Ihre Reise von Bruxelles Midi nach Essen Hbf am 02. Okt. 2024 ist wegen einer Fahrplanänderung nicht wie geplant möglich. [Your journey from Bruxelles Midi to Essen Hbf on 02 Oct 2024 is not possible as planned due to a schedule change]
Mit freundlichen Grüßen
Ihre Deutsche Bahn
Ihr bisheriger Reiseplan (nicht mehr möglich) [Your previous itinerary (no longer possible)]
Auftragsnummer: [a 12-digit number]
(below that point in the email is a description of the planned itinerary for the journey, which involved travel on an ICE train from Brussels to Cologne followed by travel on an RE train from Cologne to Essen)
This email alerts me to the fact that something is wrong, but it does not tell me anything about what I should do about it. It does not even tell me which of the two services I was going to travel on is no longer going to operate. I am at a loss for what action on my part is supposed to be prompted by this notification. What should my next steps be?
If I were travelling on the British railway system, then the faults of that system notwithstanding, I would be confident that I could turn up on the day of travel and if the train I was meant to take isn't operating, take any train on any route that's even halfway reasonable that would allow me to accomplish my journey. It is a standard expectation for travellers on the British rail system that if you buy a ticket in good faith then the rail system as a whole has to enable you to complete the journey, and if trains are cancelled or not running then you get to travel on other trains, even if those other trains are run by completely different companies. I've no idea whether the European rail system operates according to similar principles, as I have insufficient experience of it.
Edit
The trains are ICE 17 and RE 1.
