I’ve been taking it for years – the DB / City Night Line train from Brussels to Berlin / Hamburg but from the December timetable change the line no longer exists (see the routes PDF here). The train starts in Paris and will take a new route completely by-passing Belgium and stopping in Metz and Saarbrücken instead. There’s no news of why the change has been made, and the SNCB website does not even mention that the train will cease to exist. As the day train takes a good 7 hours to get to Berlin I will have no sensible option but to fly intead… So damned annoying. And why have they done this? DB is expanding its night train offerings, so I suspect the problem must be something to do with SNCB.
