Abstract: The continuous integration of Virtual Reality Art and technology has effectively promoted the visual presentation of the traditional virtual simulation. In the process of design and development, through the realistic 3D modeling design with efficient game engine technology, the actual operation environment of virtual simulation objects could be completely simulated. In this field of combining with art design and technology, with science-based rule of rail transit, abstract and mathematical analysis, independent units were used to mutually splicing mechanism way. This mechanism effectively reduces the resource cost of the running system, it ensures the quality of the picture, and improves the efficiency of the implementation.

Key words: rail transit, virtual simulation, game design thinking, dynamic line
