Abstract: In order to fully leverage the business value of various data and improve the collaborative efficiency of marshalling station operations, this paper designed and implemented an integrated data sharing platform for marshalling station areas. It designed the overall architecture, data architecture, and functional architecture of the platform, sorted out various data flows, established a mechanism for centralized data collection, data correlation analysis, and data sharing services, and implemented the unified collection, processing, and external sharing of marshalling station business data. The results of the application testing at Zhuzhou North Station show that the platform can fully leverage the advantages of data integration and sharing, effectively meet the integration and utilization needs of locomotive service information, the entire process information of train operation, and operator’s information in the marshalling station, and improve the level of data sharing and professional collaboration in the marshalling station.
