Abstract: This article proposed a kind of metro train operation visual system based on MSTS(Microsoft train simulation) platform, introduced the workflow of the visual system, and implemented the interface between visual system and ATO(Automatic Train Operation) simulation module. The interface was used to achieve the tracking control for ATO simulation module to visual system in metro train running client. It provided the possibility for the relevant test and research for the future in the visual system of ATO, but also provided a new idea for the related research of urban rail transit.
