There currently are a variety of options to travel by night train from Rosenheim (Germany) to Brzesko (Poland), taking between approximately 13 and 14 hours: Namely the IC 416 and the IC 40416. These lines are operated by Deutsche Bahn, ÖBB, České dráhy and PKP Intercity.
Deutsche Bahn (DB) exited the actual night train business in 2016. However, it operates around a dozen Intercity and Eurocity trains that run exclusively at night.
These trains only have first and second class seats. The cars remain lit throughout the night and the seats cannot be reclined.
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.
České dráhy (ČD) is the Czech national railway operator, running domestic and international passenger trains connecting the Czech Republic with neighboring countries.
PKP Intercity, Poland's national long-distance operator, connects cities across Poland and beyond its borders.
