The sleeping car or sleeper (often wagon-lit) is a railway passenger car that can accommodate all passengers in beds of one kind or another, for the purpose of sleeping. George Pullman was the American innovator of the sleeper car.
The first such cars saw sporadic use on American and English railways in the 1830s; they could be configured for coach seating during the day.
