Abstract: Railway station (yard) shunting protection system, as an important information management means of daily shunting operation of railway bureaus, has been put into use in the railway traffic control. With the further application of the system,the shunting protection system based on two-dimensional GIS is not intuitive enough in the representation of three-dimensional geographical space, which brings great challenges to the system and forms the system performance bottleneck. According to the situation, based on 3D GIS and BIM technologies, this paper studies the optimization and improvement based on the overall performance of the system, and proposes a design method of shunting protection system of railway station (yard) based on 3D GIS and BIM. The aim is to improve the overall performance of the system by using the characteristics of 3D GIS.
