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.

Fare typically consisted of rancid meat, cold beans, and old coffee. Such poor conditions discouraged some from making the journey. Most railroads began offering meal service on trains even before the First transcontinental railroad.

The "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. As competition among railroads intensified, dining car service was taken to new levels. When the Santa Fe unveiled its new Pleasure Dome lounge cars in 1951, the railroad introduced the travelling public to the Turquoise Room, promoted as "The only private dining room in the world on rails." The room accommodated 12 guests, and could be reserved anytime for private dinner or cocktail parties, or other special functions. The room was often used by celebrities and dignitaries traveling on the Super Chief. Edwin Kachel was a steward for more than twenty-five years in the Dining-Car Department of the Great Northern Railway. He said that "on a dining car, three elements can be considered -- the equipment, the employee, then passenger." In other words, "the whole is constituted by two-thirds of human parts." As cross-country train travel became more commonplace, passengers began to expect high-quality food to be
