There currently are a variety of options to travel by night train from Děčín (Czech Republic) to Karlsruhe (Germany), taking between approximately 9 and 10 hours: Namely the EN 40458 and the EC 458. These lines are operated by ÖBB, České dráhy and Deutsche Bahn.
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.
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.
