Abstract: 5G has the advantages of large bandwidth, high reliability, low latency and massive connections, and has become an indispensable and important information infrastructure for intelligent high-speed railways. In this paper, the application status of GSM-R system is analyzed, and the existing problems of GSM-R system are pointed out. Then the paper analyzes the application requirements of 5G of intelligent high-speed railways, and puts forward the corresponding application mode according to the various business requirements of the intelligent high-speed railways. The fusion applications of a new generation of communication and information technology in the railway industry, marked by 5G, cloud computing, big data, artificial intelligence, and the Internet of Things, will effectively improve the quality, safety, reliability and operational management efficiency of railway transportation services.
