China's railway system is very complicated. The data in these systems can be quite useful to promote railway’s development. But the data resources are scattered, heterogeneous due to the different system architectures. And data integration between systems is insufficient. Besides, the level of data standardization and quality is poor which make the value of the railway bigdata is hard to play effectively. The paper will start from this situation, try to make better use of railway bigdata through building a metadata management system. Promoting the standardization of data, making the data play its due value.
