I never realised there was such a differencebetween a cancelled flight and a delayed flight. This basically says that if your original flight is cancelled but somehow they would still get you there with even only a 5 minute delay, you have the right to compensation?

This means that you probably could still try to claim for compensation but I think you will have a hard time explaining why it took you almost 2 hours to get from BRU to ZYR. Almost 2 hours to get from BRU to ZYR - either you had to wait a very long time for your luggage or you took the long way around because the train ride itself is a measly 20 minutes.
