There currently are a variety of options to travel by night train from Warsaw (Poland) to Salzburg (Austria), taking between approximately 13 and 14 hours: Namely the EN 40407 and the IC 407. These lines are operated by ÖBB, PKP Intercity and České dráhy.
The Austrian Federal Railways (ÖBB) operate the Nightjet and Euronight trains (the latter together with other national railway agencies).
ÖBB night trains typically feature four types of carriages: seats, couchettes, the compact Mini Cabin, and sleepers.
While seats are only for the bravest, couchettes, Mini Cabins, and sleepers offer a more comfortable journey. The couchettes usually feature simple and rather narrow berths, while the Mini Cabin provides a compact private space for one person. Two adjacent Mini Cabins can be combined for couples. Sleepers boast beds with duvets and pillows and sometimes even a private bathroom. Couchettes accommodate up to six people, Mini Cabins are designed for one person each but two can be combined for couples, while sleepers are private compartments for one to three people.
Sleepers may include a private bathroom or shower, or sometimes just a sink. The Mini Cabin bridges the gap between couchettes and sleepers, offering solo privacy at a lower price point.
PKP Intercity is Poland's national long-distance railway operator, running domestic and international train services throughout Poland and to neighboring countries.
ČD, the Czech national railway, operates domestic and cross-border passenger trains linking the Czech Republic with its neighbors.
