There currently are a variety of options to travel by night train from Zurich to Vienna, taking between approximately 9 and 11 hours: Namely the EN 40467, and the NJ 467. These lines are operated by ÖBB.
The Austrian Federal Railways (ÖBB) operate the Nightjet and Euronight trains (the latter together with other national railway agencies). ÖBB night trains typically feature three types of carriages: seats, couchettes, and sleepers. Seats are for the bravest, while couchettes and sleepers provide a more comfortable journey. Couchettes can hold up to six people, whereas sleepers are private compartments for one to three people. They may include a private bathroom or shower, or sometimes just a sink.
