A dining car (American English) or a restaurant car (British English), also a diner, is a railroad passenger car that serves meals in the manner of a full-service, sit-down restaurant. It is distinct from other railroad food service cars that do not duplicate the full-service restaurant experience, such as buffet cars, cars in which one purchases food from a walk-up counter to be consumed either within the car or elsewhere in the train. Grill cars, in which customers sit on stools at a counter and purchase and consume food cooked on a grill behind the counter are generally considered to be an "intermediate" type of dining car.
