With the continuous development of the national economy and the deepening of transportation structure adjustment, the customer demand characteristics of railway freight are becoming more diverse. How to allocate transportation resources towards high-quality customers and further improve customer satisfaction and railway efficiency and benefits is an urgent research direction. 95306 China Railway was upgraded comprehensively, realizing centralized freight handling and providing important support for the refined analysis and differentiated service of customers. This paper proposed a feature analysis method of customer portraits based on big data, developed a customer grading evaluation model based on contribution degree, credibility, potential value, and added value, and constructed a customer-oriented differentiated freight service matching method based on machine learning. It also proposed freight service solutions based on customer value and different customer demand characteristics. By analyzing Shanghai Branch, this paper conducted a cluster analysis of customer needs based on contribution degree, economic efficiency, and timeliness. The paper then classified customers into core, key, and general categories through a hierarchical evaluation system and proposed freight service matching solutions, offering support for providing targeted and differentiated customer care and service strategies.
