Couchette car

A couchette car is a railway carriage conveying non- or semi-private sleeping accommodation.

The car is divided into a number of compartments (typically 8 to 10) accessed from the side corridor of the car, which in daytime are configured with a bench seat along each long side of the compartment. At an appropriate time in the journey, the attendant who travels in the car (or by agreement the passengers booked in the compartment) converts the compartment into its night-time configuration with two (1st class) or three (2nd class) bunks on each long side of the compartment, creating a total of four bunks in first class and six in second class.

Typically, in 2nd class the seat serves as the lowest bunk, and the back of the seat is turned into a horizontal position and serves as the middle bunk. There are two types of couchette car in countries of the former USSR: "coupé" and "platzkart". "Coupé" cars are more expensive and comfortable with 4-bunk compartments fully separated from each other and the corridor. The cheaper "Platzkart" cars, use a somewhat different layout, with no wall between compartment and corridor, only four bunks along the long sides of the compartment, and two more mounted on the corridor wall, the lower bunk folding in the daytime to become two seats.
