Abstract: To address the problems faced by railway locomotive crew members, such as difficulties in information acquisition and complex business processes, this paper proposed and designed an intelligent crew system for railway locomotives. By integrating resources of existing information systems and combining key technologies including train driving assistance, real-time monitoring, abnormal weather warning, and semantic retrieval of technical documents, the paper implemented core functions such as task planning and ride-along guidance, and adopted a combined mode of mobile terminals and fixed terminals, providing intelligent business assistance and decision support for locomotive crew members, instructor drivers, and managers at all levels. The practical application results show that this system effectively reduces the workload of crew members, improves operational safety and management efficiency, and provides valuable reference for the intelligent construction of railways.
