Abstract: After High-speed Railway entered the period of operation, unified fine management was needed for on line asset management and transportation management to improve the competitive ability of market. Using GIS integrated technology for effective management and control of assets management was an important way to implement the value of assets, value-added, profit making. This paper introduced the function and structure design, 5 key technologies. Finally, by combining the actual situation of Beijing-Shanghai High-speed Railway, it was implemented to query and display the asset location and equipment state, passenger transport marketing situation, train in transit tracking, guest rate and train density meter in the map. Finally the system running on the line would have an important effect on the asset management of High-speed Railway.
