Safe operation is the basic requirement of railway operation. Reasonable maintenance is the basic guarantee for the safe operation. Big data to analyze things as a rule of a cutting edge technology, applied to the analysis of railway detecting data processing, can improve the testing data of the use of the quality and efficiency of analysis. Based on big data, this paper points out state railway equipment management, reasonable status classification, solving the state transition probability, the prediction model is set up, providing better decision support for maintenance and repair work.

Maintenance of railway permanent way infrastructure plays a vital role in protecting the safety of railway transport. The infrastructure management of railway permanent way rarely involves effective information technology, causing the lack of supplies basis and the difficulty in tracking the relevant information of materials when problems arise in the facilities performance. This article introduced the concept of life-cycle management into the management of maintenance-of-way infrastructure and studied the information coding work on various stages of the life cycle. Simultaneously, the paper discussed how to integrate the resource of facilities and materials with the information management of maintenance-of-way infrastructure in the light of this theory.
