A dinner train is a relatively new type of tourist train service whose main purpose is to allow people to eat dinner while experiencing a relatively short, leisurely round trip train ride. This contrasts with conventional passenger trains, whose main purpose is to transport passengers to some destination as quickly as possible but which also might serve dinner on long-distance routes. The first dinner train in the United States was the "Supper Chief" that ran on the Sierra Railroad in California in the 1970s. Dinner train service was renewed in 1999 with the Sierra Railroad Dinner Train.
