Abstract: BIM technology was applied to the whole life cycle of ZPW-2000 non-insulated track circuit system by combining with the data of the section line from Huashan North Station to Lintong East Station of Zhengzhou-Xian High-Speed Railway. This paper systematically analyzed the failure effects of ZPW-2000 non-insulated track circuit by Failure Mode and Effect Analysis (FMEA), with the help of fault tree analysis and visual analysis, established a BIM model which can display the fault effect in three dimensions. On this basis, the extended application of design, construction and operation and maintenance management stages was carried out. The final BIM model can be used for student teaching or staff training, and it can also be used for reference for BIM modeling of other subsystems of the railway signal system.
