Abstract: Train consist list is a work record for handing over train set between the station and the locomotive driver, which has always been passed manually in paper form over the past decades. With the aim of covering all passenger and freight stations and providing high availability electronic information transfer service of train consist list for all passenger and freight train locomotive drivers, the technical scheme of train consist list electronic delivery system is proposed. This system adopts a centralized dual-center architecture featuring high availability, high throughput, low latency and good scalability, which consists of three parts: the central subsystem, the mobile operation subsystem and the external information interfaces. The structure of the vehicle-to-ground information transmission network of the system and its technical framework are described emphatically and the technical key points of realizing electronic transfer of correct train consist list securely and reliabily are introduced in detail. The system has been put into trial operation all over the national railways and keeps running stably and its performance meets the design requirements, covering the delivery of train consist list at all passenger and freight stations and flexibly adapting to various passenger and freight operation scenarios. In order to promote the application of the system, statistical indicators were defined to evaluate and monitor the application status of the system, and the problems existed during the trial operation and their causes were analyzed, and corresponding measures were given. In the end, relevant work that needs to be promoted in the next step is clarified and the future development is forecasted based on the application trend of 5G technology in railway.
