As a business place, the main purpose of the train dining car is to provide catering services for passengers, rather than a free rest area. Passengers occupying seats in dining cars should have corresponding consumption behaviors. Long-term occupation of dining car seats without consumption will affect the normal business activities of other passengers who come to eat and the dining car.

During the dining hours in the dining car, passengers can enjoy their seats, but they must pay for the meal or at least buy food, drinks and other commodities. During non-meal hours, the dining car may be closed to the public or provide only limited services.
