Next month, I’m planning to travel on trains from Frankfurt to Amsterdam, and then from Amsterdam to Brussels.
Both the services I wish to travel on seem to require an additional supplement to be paid - but it’s not really clear why. Can anyone help/explain?
Also, I have already made a seat reservation on the Frankfurt-Amsterdam train - would that cover the supplement in this case, or do I still need to pay the supplement separately?
