I am trying to get from Hamburg Hbf to Kopenhagen Hbf on Tuesday, 10th June night with a Global Eurail pass and would prefer to travel without having to make seat reservations.
The Eurail app is showing direct travel on EC1194 with reservations required... but when I select the "No reservations" option, I am getting an option from Hamburg Hbf to Flensburg on the same train (EC1194) but then I have to make 2 changes as shown below:


My question is... if seat reservation is required on a train, it would be required for all intermediate stations and not just for the terminating station, right? So what am I missing?
Although the information is quite clear in the app but there have been instances where the app was lacking and hence the doubt. Can someone please clarify?
Thanks in advance!
