Abstract: ［Objective］ With the rapid development of rail transit industry, intelligent manufacturing has become an important driving force for the transformation and upgrading of the industry. To provide standardized guidance and support for equipment manufacturers within the industry, it is necessary to conduct research on intelligent manufacturing standard systems for the rail transit industry. ［Method］ An overview of the current state and development trends of intelligent manufacturing in rail transit industry is conducted. A comprehensive and scientific framework for the intelligent manufacturing standard system of rail transit industry is proposed, covering technical, managerial, and application levels. The primary content of the standard system under this framework is described. Recommendations for the implementation and promotion of the intelligent manufacturing standard system of rail transit industry are provided. ［Result & Conclusion］ The proposed standard system, through the establishment of comprehensive standards, enhanced supply chain collaboration, and deepened application of intelligent manufacturing technologies, can promote further development of intelligent manufacturing in rail transit industry. In the future, with the continuous maturity and promotion of the intelligent manufacturing technology application, the rail transit industry is expected to experience broader development prospects.
