This paper aims to promote the deep integration of artificial intelligence technology and railway business, and enhance the level of railway operation and management. Focusing on the current needs of railway digital transformation and intelligent development, it integrates industry technological trends, cutting-edge technologies in multiple fields, and the actual business requirements of railway transportation. The study deeply analyzes the evolutionary process, current status characteristics, and development challenges of China′s railway digital transformation, proposes the objectives and overall architecture of China′s railway digital transformation. And then it explores the integration and application paths of new-generation information technologies such as artificial intelligence in the fields of railway engineering construction, transportation services, safety assurance, business development, etc. Additionally, it offers development suggestions for digital transformation. The research conclusion highlights that China′s railways should be based on the intelligent railway system framework, promote the digital transformation and intelligent development through collaborative advancement, achieve the transition from scale leadership to comprehensive technological and service leadership, and provide strong support for building a country with strong transportation network.
