摘要:Track Maintenance is crucial for the safe and efficient of railway transportation. After analysis of foreign management techniques for high-speed railway track maintenance, combined with the characteristic of passenger dedicated line in China, this paper has explored new ideas of the information system of passenger dedicated line track maintenance and at the same time researched on the theory and method of system construction in depth. Combined with parts of after-operation data of Beijing-Tianjin intercity passenger dedicated line and based on the key technologies and system design in the paper, a prototype information system of track maintenance for Beijing-Tianjin intercity passenger dedicated line has been developed.
