Loco and Car Tracing Technique in the New Generation of Synthetic Automation System for Marshalling Yard;

Study on operation management indexes system for marshalling yards;

Analysis and Study on the Time Interval Control of Rolling Cars for Break up Operation in Marshalling yards;

Design of Field Operation System for marshalling station based on PDA;

Research and implementation of automatic establishment for classification plan of marshalling stations;

Research on computer integrated process system for marshalling station;

How to improve and upgrade the technology and equipment for the piston retarder speed control system in order to meet the requirement of more brake energy for over loading railway wagons in classification yards.

But until now, there are not any papers in the science journals at both home and abroad to describe the trolley how to affect the forces acted on the rail in the classification yard.

This paper gives a brief introduction to the general condition of Nanxiang classification yard and displays the function and features of the hump automatic system in the up yard and management information system in station.
