Doubly painful, now that people are once again more open to the use of a sleeper train to avoid flying (for environmental reasons, or just not having to deal with airports).

ÖBB took over Deutsche Bahn's sleepers, which coincided with the retiring of the last sleeper train from/to the Netherlands (bugger me). But their service does seem to be working pretty well.

I missed an opportunity to travel from Milan to Paris by Thello's sleeper train due to the railway strikes in France this year, unfortunately.

I really wish the EU or collaborating national governments would invest more in sleeper train services by taxing flights. It's much more sustainable, and the real kicker is this: yes, a train takes longer, but in a sleeper train you just wake up with a complimentary breakfast early in the morning in the middle of a city hundreds of kilometres from where you started.
