There currently is one option to travel by night train from Salzburg to Brussels, taking between approximately 12 and 13 hours: Namely the NJ 40468 operated by ÖBB.
The Austrian Federal Railways (ÖBB) operate the Nightjet and Euronight trains (the latter together with other national railway agencies). The ÖBB usually offer three types of carriages in their night trains: seats, couchettes, and sleepers. Seats are for the bravest, while couchettes and sleepers provide a more comfortable journey. Couchettes accommodate up to six people, while sleepers are private compartments for one to three people. They may include a private bathroom or shower, or sometimes just a sink.
