Abstract: In order to implement the sharing and utilization of railway infrastructure information resources, starting with the analysis of railway infrastructure whole life cycle information based management planning, combined with the specific requirements of digital delivery of design results in the design stage to the construction stage of railway construction projects, this article proposed a digital delivery scheme of railway design results based on Metadata. It provides a technical path for the unified semantic delivery of design results data and the ultimate realization of information sharing in the whole life cycle of railway infrastructure.
