Abstract: From the business processes of railway engineering construction organization and management, in view of the defect that the result were not accurate and low efficiency by artificial means in traditional construction organization schedule management, this article proposed the railway engineering construction organization image schedule system, designed the overall structure and the application function of the system, decomposed the task structure of the whole project gradually, established the professional icon and legend, discussed the key technologies used in the system in detail. The construction organization image schedule management was implemented by using SVG technology and the calculation method of schedule deduction. The system has been applied in several railway projects under construction, implemented the construction organization informatization and visualized management, met the requirements of organization and management of engineering construction.
