I booked a trip from Hamburg Hbf to Brussels/Bruxelles Midi, entirely with Deutsche Bahn trains. Later, I got an email from Deutsche Bahn stating the following:
Due to a timetable change, your journey from Hamburg Hbf to Bruxelles Midi on 02 February 2024 cannot be carried out as described. Click "Get current information here" for alternative journey options to your destination.
The requirement for you to travel on a specific train on your booked connection has been lifted. This means you can also use your ticket on other Deutsche Bahn long-distance trains (e.g. ICE/IC/EC), as well as local trains and S-Bahn trains.
Please note that you must book a new reservation if your connection requires one (e.g. trains to France).
While this is nice, what's confusing to me is the last section where it states that I must book a new reservation if my connection requires one, with the example being trains to France. Does this apply to the itinerary I'm making, where I'm planning to exclusively use Deutsche Bahn trains? For going from Germany to Bruxelles Midi I'm planning to get on an ICE train in Köln/Cologne, specifically (there are no direct trains from Hamburg Hbf to Bruxelles Midi).
