Abstract: Marshalling yard is the key link of freight transportation and the distribution points of large number of train vehicles. How to make sure the safety of marshalling yard operation is the important part of ensuring the safety of railway freight transportation. Starting with ‘service quality ring’, the formation process of marshalling yard operation safety quality can be divided into three related stages, designing and standard-setting, process operating, operation result analyzing and operation safety quality improving. With a marshalling yard being taken as an example, an in-depth analysis was made into the operation safety quality of marshalling yards from the aspects of safety problem statistics, age and educational structure of the workers, wage performance appraisal, elements of equipment technology information, the process and result analysis of operation, etc. Based on all above, three control measures for the operation safety quality of marshalling yard were put forward from perspectives of preventive control, process control and result control. The results show that Marshalling yards must start with preventive control measures while focusing on process control and paying attention to the result control in order to ensure the operation safety, stability and smooth transportation of marshalling yards.

Key words: marshalling yard, practice, safety, control, service quality ring
