Overnight Accommodation

A night train is an overnight rail service, not one accommodation type. A departure may offer ordinary seats, couchettes, sleeping cars, or a mixture of them. Choosing a night train does not automatically give you a bed. The booking needs to name the accommodation or seat product you are buying.

Couchette

A couchette is a multi-berth sleeping compartment. In many services, the space starts as seats and is changed into bunks at night. A couchette may be shared with other travellers, but some operators also sell the whole compartment privately. The number of berths, bedding arrangement, privacy options and washroom facilities depend on the named service.

Layouts differ between operators. ÖBB Nightjet has standard couchettes for four to six people and comfort couchettes for up to four, with bedding and washrooms or toilets in the coach. European Sleeper's Classic product has four, five or six places and converts from seats by day to couchettes at night, with facilities in the corridor. SNCF Voyageurs' first-class couchettes have four berths and its second-class couchettes six. Snälltåget's night-train compartment has six berths and changes from seats to beds at bedtime. These counts describe the named products, not a Europe-wide layout.

Sleeper or sleeping car

A sleeper or sleeping car is an operator-defined bed product rather than a universal occupancy category. Nightjet offers sleeping compartments for one, two or three people, while European Sleeper's Comfort Plus sleeping-car compartment has up to three places, the same maximum as its Comfort Standard couchette. The product name does not guarantee the same occupancy or facilities everywhere. Nightjet products range from a compartment with a washbasin to a Plus compartment with a private shower and toilet. European Sleeper's Comfort Plus sleeping-car compartment has an in-compartment washbasin and corridor toilets.

The product name matters when you want a bathroom, a made-up bed or included extras. A single sleeping place in a double or triple compartment can still mean sharing with another passenger unless the whole compartment is booked privately.

Berth

A berth is one individual sleeping place within a compartment. It describes the place you occupy, not how private the room is or which facilities it has. A berth may be upper, middle or lower, and linen or bedding may be supplied or prepared differently by the operator.

Snälltåget illustrates the distinction clearly: a shared-berth booking places you in a six-berth compartment with other travellers, while its private option reserves the same six-berth layout for your traveller group. SNCF's first-class couchettes have lower and upper berths; its second-class couchettes have lower, middle and upper berths.

Private compartment

Private compartment describes who occupies the compartment, not one fixed comfort level. It can apply to a seating compartment, a couchette or a sleeper. Nightjet offers private versions of all three. European Sleeper offers a private Classic couchette, and Snälltåget's private night-train compartment still contains six berths.

Buying a whole compartment is what keeps strangers out. It does not turn a couchette into a sleeper, add an ensuite bathroom, or remove the unused berths from the physical room. When a booking says private, read the product name as well so you know whether you are getting seats, couchettes or beds and where the facilities are.

Mini Cabin

Mini Cabin is an ÖBB Nightjet product name for a compact sleeping pod in new-generation Nightjet stock. It is separate from a conventional couchette, a sleeping-car compartment and a whole private compartment. The pod has nearby hand-luggage and shoe lockers, a reading lamp, storage, a folding breakfast table, a mirror, an attendant-call control and NFC locking. Adjacent pods can connect.

Use Mini Cabin only when the exact Nightjet booking names that product. It is not a generic European term for a sleeper or a private room, and the product name alone does not promise a private bathroom. On new-generation Nightjet services, children aged 10 and over may travel in a Mini Cabin when accompanied by an adult.

What the choice changes when you book

The same night train can sell a seat, one berth in a shared compartment, a whole private compartment, a sleeper berth or a branded pod. Those choices change whether you sleep, whether strangers share the room, how the bed is prepared and where toilets or washbasins are located. Availability is tied to the exact departure and product, so a route can use different accommodation layouts on different trains.

A ticket or rail pass does not select a bed unless the named product includes accommodation. Read the accommodation name, occupancy, privacy arrangement and listed facilities together. Rules for reservations, pass-holder supplements, booking windows and availability belong to the specific operator and departure rather than to the word night train.

Common confusion and exceptions

Night train is the service; couchette, sleeper, berth, private compartment and Mini Cabin describe choices within that service. Couchette usually points to a multi-berth layout, while sleeper is an operator-defined bed product, but neither word fixes a universal berth count or bathroom arrangement. A berth is one place, while private refers to who else is allowed into the compartment.

Operator language can be different. Caledonian Sleeper uses names such as Caledonian Double En-suite, Club En-suite and Classic Room for private rooms, and sells a separate Seated Coach. Those labels describe that operator's UK products; they do not mean every sleeper train has a double bed, an ensuite room or continental-style couchettes.
