Overnight Accommodation

A night train is an overnight rail service, not an accommodation type. One departure can sell ordinary seats, couchettes, sleeping compartments or branded pods. A night-train ticket therefore does not automatically include a bed: the booked product must specify the seat or sleeping place.

Couchette

A couchette is a multi-berth sleeping compartment. On many services, the daytime seats are converted into bunks at night. You can book a berth in a compartment shared with other travellers, while some operators also sell every berth in the compartment to one party. The berth count, bedding, 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 are named products, not a standard European layout.

Sleeper or sleeping car

A sleeper or sleeping car is an operator-defined bed product, not a universal occupancy category. Nightjet offers sleeping compartments for one, two or three people. European Sleeper's Comfort Plus sleeping-car compartment has up to three places, the same maximum as its Comfort Standard couchette. Do not assume that the word sleeper always means private or ensuite. Nightjet products range from compartments with a washbasin to Plus compartments with a private shower and toilet. European Sleeper's Comfort Plus compartment has a washbasin inside and toilets in the corridor.

One sleeping place in a double or triple compartment can still mean sharing with another passenger unless the whole compartment is booked privately. The named product determines whether you get a made-up bed, a washbasin, a private bathroom or other included extras.

Berth

A berth is one individual sleeping place within a compartment. It describes the place you occupy, not the privacy of the room or its facilities. A berth may be upper, middle or lower, and operators prepare or supply bedding in different ways.

Snälltåget illustrates the distinction: one berth places you in a six-berth compartment with other travellers, while its private option reserves the same six-berth layout for your party. 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 a fixed comfort level. It can be 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.

Booking the whole compartment keeps other passengers out. It does not turn a couchette into a sleeper, add an ensuite bathroom or remove unused berths from the room. The product name still tells you whether the compartment contains seats, couchettes or beds and where the facilities are.

Mini Cabin

Mini Cabin is ÖBB Nightjet's name for a compact sleeping pod in its new-generation trains. It is different from a conventional couchette, sleeping-car compartment or 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.

Mini Cabin is not a generic European term for a sleeper or private room, and it does not promise a private bathroom. On new-generation Nightjet services, children aged 10 and over may use a Mini Cabin when accompanied by an adult.

What the choice changes when you book

Keep four details separate when comparing overnight options:

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 affect whether you sleep, whether strangers share the room, how the bed is prepared and where toilets or washbasins are located. Accommodation layouts can also differ between trains on the same route.

A ticket or rail pass does not provide a bed unless the named product includes accommodation. Consider the accommodation name, occupancy, privacy arrangement and listed facilities together. Reservation rules, pass-holder supplements, booking windows and availability belong to the specific operator and departure, not to the words 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 means 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; private describes who else may occupy the compartment.

Operators may use their own names. Caledonian Sleeper sells private rooms called Caledonian Double En-suite, Club En-suite and Classic Room, as well as a separate Seated Coach. Those are UK product names, not evidence that every sleeper train has a double bed, an ensuite room or continental-style couchettes.
