Corail is the name given to a class of passenger rail cars of the SNCF that first entered commercial service in 1975.

[citation needed] The acquisition of the Corail coaches was a huge investment for SNCF with nearly 4000 carriages ordered, and represented a major leap in quality of service for French rail passengers.

[2] When introduced, Corail carriages were painted in two tones of grey with a sharp flash of orange on the doors.

Lunéa night trains operate on a number of domestic routes, offering a first and second class couchette service.

Passengers travel in compartments of four or six bunks, and are provided with a pillow, lightweight bedsheet and blanket.
