There currently are a variety of options to travel by night train from Radymno (Poland) to Munich (Germany), taking between approximately 17 and 18 hours: Namely the IC 417 and the EN 40417. These lines are operated by České dráhy, ÖBB, PKP Intercity and Deutsche Bahn.
České dráhy (ČD) is the Czech national railway operator, running domestic and international passenger trains connecting the Czech Republic with 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.
Seats are for the bravest, while couchettes, Mini Cabins, and sleepers provide a more comfortable journey. In the couchettes, you can find simple and rather narrow berths. The Mini Cabin is a compact sleeping option for solo travelers – two Mini Cabins can be combined for couples. Sleepers are equipped with proper beds 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.
PKP Intercity, Poland's national long-distance operator, connects cities across Poland and beyond its borders.
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.
In these night trains, there are only first and second class seats. The lights stay on all the time and there is no way to recline the seats.
