There currently are a variety of options to travel by night train from Karlsruhe to Göttingen, taking approximately 4 hours: Namely the NJ 470, and the IC 60470. These lines are operated by ÖBB, and DB.
The Austrian Federal Railways (ÖBB) operate the Nightjet and Euronight trains (the latter together with other national railway agencies). The ÖBB usually offer three types of carriages in their night trains: seats, couchettes, and sleepers. While seats are only for the bravest, couchettes and sleepers offer 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.
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.
