Sleeper Compartments:
Sleeper Compartments have washbasins, soap, towels, razor plug, mineral water, and a lockable door. The berths come with pillow, sheets, and a duvet or blanket. Stewards are present in the sleeper cars to assist you and take care of all border crossings procedures for you. Many of the stewards speak the languages of the countries the train will pass through as well as English. Compartments are gender specific unless booked by couples or families. Fares for sleepers require a 1st class ticket or a rail pass plus the sleeper supplement. 1st class/rail pass travelers can book a single, double, or triple sleeper. Single passengers can reserve a double sleeper but they may have to share with another passenger based on availability.

Couchettes:
Couchettes are compartments with berths for 4-6 people. Each berth has a pillow, sheets and blankets. Washbasins are not available in the compartments and restrooms are at the end of the car. Berths can be booked individually or in groups. Compartments are non-gender specific and travelers are expected to sleep in their day clothes. Stewards are available only on international routes. Fares for couchettes require a 1st or 2nd class ticket or a rail pass plus the couchette supplement.

Sleeperettes:
Sleeperettes are seats in open coach cars that recline to allow you to sleep more comfortably. Seats may have small head pillows attached but no blankets are provided. Fares for sleeperettes require a 1st or 2nd class ticket, or a rail pass and a reservation. There is normally no additional cost for sleeperettes. However, some hotel trains may charge a higher reservation fee for seats. Hotel trains combine long distance night travel with the security and privacy and comfort of a hotel stay. All compartments have locking doors and access to dining cars. There are three levels of accommodation: Tourist, First Class, and Luxury Class. There are reclining 2nd class sleeperette seats on certain trains. Tourist class accommodations include 4 beds to a compartment. Toilets are found outside the compartment in the car. First class accommodations include compartments with one to two beds. Toilet and shower facilities are located outside the compartment in the car. Luxury class accommodations include one to two beds per compartment. They also include a private toilet and shower within the compartment.
