A special car operation system comprising: a passenger prediction unit to predict the number of passengers on a train scheduled to operate and output passenger count information indicating the number of passengers predicted; and a car-count determination unit to determine the number of special cars in the train on a basis of the passenger count information output by the passenger prediction unit and output car count information indicating the number of special cars determined; an arrangement-position determination unit to determine a position where a special car is to be disposed in the train on a basis of the car count information output by the car-count determination unit and output arrangement position information indicating the position determined; a platform-position acquisition unit to estimate a stop position of the special car on a platform when the train arrives at a station where the train is scheduled to arrive on a basis of the arrangement position information output by the arrangement-position determination unit and output platform position information indicating the stop position of the special car estimated; and an output generation unit to generate an output signal for guiding a passenger who is going to get on the special car to the stop position of the special car on the platform on a basis of the platform position information output by the platform-position acquisition unit, output the output signal generated to an output device at a predetermined time point before the train arrives at the station where the train is scheduled to arrive, and cause the output device to provide output based on the output signal, wherein the special car is a car with a special specification which is different from a specification of a general car and which serves for a specific passenger type, the passenger prediction unit predicts, on a basis of a plurality of predetermined passenger types, passenger types of respective passengers who get on the train scheduled to operate and predicts the number of passengers of each of the passenger types predicted, thereby outputting the passenger count information indicating the number of passengers of each of the passenger types predicted, and the car-count determination unit determines, as to a plurality of predetermined types of special cars, the number of special cars for each of the types of special cars corresponding to the respective passenger types on a basis of the passenger count information output by the passenger prediction unit, and outputs the car count information indicating the number of special cars determined for each of the types. a passenger prediction unit to predict the number of passengers on a train scheduled to operate and output passenger count information indicating the number of passengers predicted;
