There currently is one option to travel by night train from Innsbruck to Budapest, taking between approximately 8 and 9 hours: Namely the EN 40467 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. While seats are only for the bravest, couchettes and sleepers offer a more comfortable journey. Couchettes can hold up to six people, whereas sleepers are private compartments for one to three people. They sometimes include a private bathroom or even a shower, sometimes only a sink.
