Night train from Offenburg to Hanover
There currently are a variety of options to travel by night train from Offenburg (Germany) to Hanover (Germany), taking between approximately 5 and 7 hours: Namely the ICE 4, the NJ 470, and the ICE 100. These lines are operated by DB, and ÖBB.
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 three types of carriages: seats, couchettes, and sleepers. Seats are for the bravest, while couchettes and sleepers provide a more comfortable journey. Couchettes can hold up to six people, whereas sleepers are private compartments for one to three people. They may include a private bathroom or shower, or sometimes just a sink.
