There currently are a variety of options to travel by night train from Berlin (Germany) to Copenhagen (Denmark), taking between approximately 8 and 11 hours: Namely the EN 344 and the 10300. These lines are operated by RDC and Snälltåget.
RDC Deutschland operates the RDC Euronight night train between Berlin and Stockholm three times a week, with stops in Hamburg, Copenhagen and several Swedish cities along the way.
The train offers two sleeping car categories. In the 1st class sleeper, private compartments accommodate up to three people with wide, made-up beds, a private bathroom with shower and toilet, and breakfast served directly to the compartment. The 2nd class sleeper has two-person compartments with a washbasin and 230V socket in the compartment; the toilet is in the corridor. 2nd class sleeper compartments can be booked privately or shared — in mixed or women-only configuration.
Couchette compartments accommodate up to six people and can be booked privately or as individual berths. All berths come with a pillow, sheet, and blanket. Washrooms and toilets are available in the carriage.
The seating car is the most affordable option, offering compartments for up to six people as well as open-plan carriages. Power sockets are available at every seat and a seat reservation is included in the ticket price. Toilets are located in the vestibules at the end of the car.
Passengers in sleeping car compartments — both 1st and 2nd class — receive breakfast delivered to their compartment. Couchette and seating car passengers are not provided with breakfast.
Snälltåget offers night travel with various comfort levels on night trains between European cities.
Accommodation ranges from individual seats in coaches to shared compartments with up to six berths and private compartments for small groups. All beds include bedding and blankets.
In shared and private compartments, seats convert to berths at night. Each compartment features three berths on each side with ladders to reach the upper berths. Private compartments are ideal for groups seeking more privacy.
Animals are permitted in private compartments only. Bikes are not allowed, but collapsible bicycles can be transported as hand luggage or stored on luggage racks.
