Abstract: This paper studied the railway construction management platform to improve the management efficiency, construction safety, quality and progress in the process of railway construction. Through BIM technology, the paper summarized the past experiences of railway engineering construction, and adopted the structure form based on .Net framework, Microsoft.net operation library, 3D virtual reality engine unity3D 5.5.0f3 to complete the construction of railway construction management platform, and implement the information based management and control of the whole process of railway engineering construction. It provides reference for the information based construction of railway engineering, and gives practical data for the promotion of information based work.
