There currently are a variety of options to travel by night train from Munich (Germany) to Zawiercie (Poland), taking between approximately 11 and 13 hours: Namely the IC 406 and the IC 40406. 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).
The ÖBB usually offer four types of carriages in their night trains: seats, couchettes, Mini Cabins, 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 can hold up to six people. The Mini Cabin is a private space for one person – two adjacent Mini Cabins can be connected for traveling together. 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.
ČD, the Czech national railway, operates domestic and cross-border passenger trains linking the Czech Republic with its neighbors.
PKP Intercity, Poland's national long-distance operator, connects cities across Poland and beyond its borders.
