Night train services in Europe, especially the west, have declined sharply in the last two decades. As short-haul flights boomed, sleeper carriages were allowed to age out of use without being replaced. All connections between Germany and France, Denmark and the Netherlands were cut in 2014, and in 2016 Deutsche Bahn quit the industry all together, selling its remaining sleeper carriages to the Austrian state railway company ÖBB. Since then, though, there has been something of a comeback: a ‘Nachtzugboom’, as a recent Die Zeit podcast put it.
