In order to perceive a whole railway service, we need to evaluate hospitality of staffs and crews, and provide the information during train delays such as the train schedule and the conditions of equipment of vehicles and stations. In these studies, the train information in Japanese transportation service is focused on, and an appropriate effect of transport information for the passenger´s behavior is analyzed and an appropriate concept of information service is presented for the railway transportation system. The properties of railway service are reviewed by the SSM-IA analysis and the train information services which can elevate the railway service values are pointed out. Next, the usability of information items such as passenger´s congestion state and the train position inside lane are suggested by the analysis of the user´s preferences survey. In addition, the relations between the customer´s satisfaction and information services are viewed from the effect on passenger´s behavior in the transportation infrastructure.
