There currently are a variety of options to travel by night train from Bonn to Mannheim, taking between approximately 2 and 3 hours: Namely the IC 60403, the NJ 425, the NJ 40425, and the NJ 403. 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. 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 sometimes include a private bathroom or even a shower, sometimes only a sink.
