Gick bara genom att boka ett sovvagnståg i Polen och hittade 4 personer Couchette och 6 Person Couchette.
Seat 61 har förmodligen den bästa beskrivningen av facket som jag har sett.
What are couchettes?
Couchettes are basic, inexpensive sleeping accommodation, with 6 bunks per compartment. On many routes you can also choose to travel in a less-crowded 4-berth compartment, for only a few euros more. By day, a couchette compartment is an ordinary seating compartment, with three-a-side bench seats facing each other (the picture of the French couchette below shows the middle bunk lowered to form the seat back in daytime mode). At night, the seats convert to bunks. Each bunk is basically a padded ledge supplied with pillow, sheet and blanket which you arrange yourself. Each berth has its own reading light. Washrooms and toilets are available at the end of the corridor. The sexes are normally mixed in couchettes, as you do not normally fully undress, but on many routes women can ask for a berth in a ladies-only compartment. Couchette cars come in many different designs, all based on the same format. Here are some some German City Night Line ones:
ADDITIONAL INFO
Det är uppenbart att vissa tåg, enligt min bästa förståelse i Polen, ger Billig eller Cut-Price Couchette Skillnaden mellan det vanliga och snittpriset är linne, från intercity.pl:
With a Cut-Price Couchette, passengers travel in a couchette compartment furnished with six berths. Bedding is not provided, but the price includes a disposable sheet. Cut-Price Couchette tickets can be purchased at ticket offices, from the conductor and online.
