Abstract: Train consist information is the core data for railway traffic organization and traffic control. Accurate, timely and reliable collection, transmission and sharing of train consist information is an important task of railway informatization. At present, the implementation of the train consist list electronic delivery system has covered the entire railway network, which can preliminarily ensure the accuracy and timeliness of data collection of train list information from original sources. To meet the needs of the existing railway information systems for train list information, a data sharing solution based on the train consist list electronic delivery system is proposed, in which big data collection, preprocessing, storage and management technologies are adopted to further improve the quality of train list information and to provide efficient, convenient and safe data sharing services for related railway information systems as well as to support the development of new extended applications such as real-time train tracking and safety distance warning. This solution can help improve the alpplication effects of the train consist list electronic delivery system and provide strong support for improving the quality and efficiency of railway operation and ensuring traffic safety.
