On the basis of analyzing the previous papers published at home and abroad, and considering the special characteristic of Chinese railways, the paper presents a multi objective programming model of car flow routing with bidirectional heavy and empty cars in a railway network, in which there are six objectives, twelve system constraints and two sets of non negative constraints.

Taking current "Train Path Diagram of East China Railway Network" andrelevant operation data as input,a calculation of train flow path is carr.

In the exploitation andapplication of Railway Sub-Administration command control system, thevisualized maintenance method that employs graphic interface to divide trainflow group number can provide a convenient and ocular way to handle themaintenance of train flow path between current train system and commandcontrol system.

This paper analyzes current problems of train flow paths of the railway network in our country,explains the meanings of optimizing train flow paths,and describes the railway network by mathematics.

It was discussed the constructive diagram, the plan of wagon flow pathand its algorithm of special path about Aided Decision Making System of Railway Container Transportation Path.

A heuristic algorithm is presented to find the specific wagon flow path in railway network, and its efficiency is discussed as well.

This paper is concerned with the optimal choice of wagon paths with some constraints in railway.
