What is a "couchette" in the context of train travel?

A "couchette" refers to a sleeping compartment on a train that provides basic sleeping accommodations for passengers. Typically found on overnight trains, couchettes are designed to offer a more comfortable travel experience for those needing rest during longer journeys. They generally consist of a shared compartment with fold-down bunks or reclining seats, allowing passengers to sleep while the train is in motion.

This concept contrasts with other elements of train travel, such as a railway station, which is simply a place where trains stop, or dining cars, which focus on providing meals for passengers. Similarly, a type of ticket class, while essential to the pricing and booking structure of train travel, does not relate directly to the physical sleeping arrangements offered within train compartments. Thus, understanding the role and function of couchettes provides clarity about their importance in offering travelers restful options on overnight routes.
