Abstract: The traditional working mode of railway construction organization design has problems such as data scattered, difficult integration, low work efficiency and difficult quality assurance, which are difficult to meet the needs of rapid development of railway construction. For this reason, this paper proposed a method of automation design of the whole process for railway construction organization based on big data and information based technologies, and developed an integrated compilation system for railway construction organization and cost. The research content of the paper included the sub processes from field survey, office work sorting to production results. The paper used mobile terminal equipment to implement the automatic collection of field survey data, and realized the functions of data sharing, data integration, data analysis and production results on the PC side. The application of the developed system significantly improved the work efficiency of railway construction organization design, ensured the quality of results. It has certain reference significance for the automation design of construction organization of linear projects such as railways and highways.
