Abstract: Aiming at the problems of numerous ticketing and reservation subsystems, complex technology, high training cost, strict environmental requirements and limited number of service users, this paper proposed a cloud training platform scheme for China railway ticketing and reservation system. The scheme had the functions of convenient and safe Internet access, real-time linkage between production environment and simulation environment, intelligent platform management, multi scene learning environment and multi center online examination. The practice proves that the proposed scheme is intelligent, efficient and convenient, saves a lot of manpower and time costs for the existing system, greatly improves the synchronization efficiency of cross network data and the coordination ability of remote interaction, and has certain economic benefits and social value.
