This paper studies the problem of unbalanced train caused by speeding up and affects the operation of marshalling yard and puts forward a new model of marshalling yard operation organization simulation analysis based on the flow analysis. The model accurately describes the marshalling and maneuvering of marshalling yard The machine uses the coordination conditions among the three parts to naturally reveal the interrelationship between the condition of changing traffic flow (train operation diagram, marshalling plan, etc.), marshalling station equipment and measures of different transport organizations, and gives the method for analyzing the performance of marshalling yard operation organization Computer simulation method. On the basis of this, using the developed simulation software system, taking a certain trunk line as an example, the influence of freight flow changes on the working organization of the marshalling tower was investigated before and after the acceleration of passenger traffic in 1993, 1997 and 2002 Quantitative analysis and evaluation. The research shows that this simulation model provides a more accurate method and method for analyzing and evaluating the new operating organization effect of marshalling yard.
