There currently are a variety of options to travel by night train from Briançon (France) to Paris (France), taking between approximately 11 and 13 hours: Namely the INTERCITES DE NUIT n° 5790 and the INTERCITES DE NUIT n° 5792. These lines are operated by SNCF.
The National Company of the French Railways (SNCF) operates a handful of lines throughout continental France.
These night trains typically feature seating carriages and couchette carriages in first and second class.
Couchette carriages generally have 4-person compartments in first class and 6-person compartments in second class. The berths are simply designed in both classes and are about 1.9 meters long.
Yes, for more privacy, entire 4-person compartments can be booked exclusively. This can also be done for a group.
In first class, only four people share a compartment, the berths are wider, and travelers have access to station showers in Paris and Toulouse. Second class accommodates six people per compartment and allows bicycles to be brought for an additional fee of 10 euros – a plus for cyclists.
You should bring your own food as there is no restaurant on board. Alternatively, you can pre-order meals and drinks or eat before departure. First class travelers receive a small breakfast. Each passenger receives a night kit with refreshing towelette, dental cleaning tablet, sleep mask, earplugs, and water.
