There currently are a variety of options to travel by night train from Buchs to Graz, taking approximately 9 hours: Namely the EN 40465, the NJ 465, and the NJ 1465. 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. While seats are only for the bravest, couchettes and sleepers offer a more comfortable journey. Couchettes accommodate up to six people, while sleepers are private compartments for one to three people. They sometimes include a private bathroom or even a shower, sometimes only a sink.
