Dining Car

A dining car (British English: restaurant car) or diner is a railroad passenger car that serves meals on a train in the manner of a full-service, sit-down restaurant. It is distinct from other types of railroad food service cars that do not duplicate the full-service restaurant experience, principally cars of various types 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.

Before the inclusion of dining cars in passenger train became common practice, a rail passenger's only option for meal service in transit was to patronize one of the roadhouses often located near the railroad's water stops. Fare typically consisted of nothing more than rancid meat, cold beans, and week-old coffee. Such poor conditions understandably discouraged many Americans from making the journey westward.

Most railroads began offering some form of meal service on their trains even before the completion of the First Transcontinental Railroad. By the mid-1880s, dedicated dining cars were a normal part of all long-distance trains departing from Chicago for points westward, save for those of the Santa Fe, who relied on America's first interstate network of restaurants to feed its passengers en route. The legendary "Harvey Houses," located strategically along the line, served top-quality meals to railroad patrons during water stops and other planned layovers and were favored over in-transit facilities for all trains operating west of Kansas City
