There currently are a variety of options to travel by night train from Linz (Austria) to Dąbrowa Górnicza (Poland), taking between approximately 8 and 9 hours: Namely the IC 40406, the IC 406 and the EN 406. These lines are operated by PKP Intercity, ÖBB and České dráhy.
PKP Intercity is Poland's national long-distance railway operator, running domestic and international train services throughout Poland and to neighboring countries.
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 sometimes include a private bathroom or even a shower, sometimes only a sink. The Mini Cabin offers a more affordable private alternative with its own compact sleeping space for one person.
České dráhy (ČD) is the Czech national railway operator, running domestic and international passenger trains connecting the Czech Republic with neighboring countries.
