This research aims to know and analyze the direct and indirect impacts of service quality and ticket price policy on trust and also its impact on the passenger loyalty of Soekarno-Hatta Airport Train, Cengkareng, Indonesia. The main problems are that the service quality provided by Soekarno-Hatta Airport Train is not maximal and that the ticket price of the Soekarno-Hatta Airport Train is relatively expensive because the passengers still have to use another transportation mode to go to the station. This research uses a quantitative approach with Structural Equation Modelling, assisted by the Lisrel program with a sample of as many as 150 passengers. The results of this research prove that service quality and ticket price policy have both direct and indirect impacts on passenger loyalty through the mediation of passenger trust. The key finding is that the policymakers can take advantage of the findings of this research, especially the crucial aspects in the questionnaires on service quality and ticket price policy which are considered not optimal by the passengers of Soekarno-Hatta Airport Train. So, passenger loyalty can be enhanced through the improvement of service quality and ticket price policy supported by passenger trust.

This study aims to analyze the improvement of the operational performance of Indonesia’s Soekarno-Hatta Airport train through service quality which is mediated by train passenger loyalty and passenger satisfaction. The main problems in this study are the use of the same railway for long-distance train, airport train, and commuter Line train, the limited use of airport railway with four schedules, the headway which becomes 30 minutes since the number of travels becomes 82 trips, and the tariff being applied now is considered as burdening the passengers. The research method uses a quantitative analysis approach with the technique of Structural Equation Modeling-Lisrel. Data collection is done through observation and questionnaire distribution. The respondents are 306 passengers of trains heading for Soekarno-Hatta Airport. The benefit of this study for the domestic railway company is that by improving service quality, passenger loyalty and satisfaction, it will improve the operational performance of airport trains. The result of this research indicates the significant influence of service quality variable on passenger loyalty through passenger satisfaction, the significant influence of service quality variable on operational performance through passenger satisfaction and passenger loyalty as well as the significant influence of passenger satisfaction variable on operational performance through passenger loyalty.
