Abstract: Artificial intelligence is increasingly integrated into various fields of economic development and has a profound impact on the changes in the operating methods of various industries. With the continuous development and application of artificial intelligence large models, higher requirements have been put forward for data, algorithms, computational power, and other aspects. At present, artificial intelligence has played an important role in multiple fields of the railway industry, but there are still some problems in the application of railway artificial intelligence in platform capabilities, technical systems, and business application construction. This paper analyzed the current application status and requirements of railway artificial intelligence, proposed the construction goals of the railway artificial intelligence platform, designed the overall architecture and platform functions, and studied the key technologies of the railway artificial intelligence platform. It has positive significance in promoting the systematic application of artificial intelligence in the railway industry.
