Reconstruction and Development of Existing Railways to Operate Suburban Railways under the"Integration of the Four Networks":A Case Study in Xi'an-Huyi Railway
In response to the relevant issues of urban operation transformation of existing railways under the background of"four network integration,"this paper investigates new ideas and models for urban operation transformation of existing railways,taking the Xi'an-Huyi railway transformation as an example.First,based on the function of urban railways,this study assessed the construction models and operational characteristics of existing railways for operating urban trains and identified current problems,such as incomplete technical standards,a low degree of network integration,a low passenger flow intensity,and significant operational losses.Second,taking the operation of urban trains on the Xi'an-Huyi railway as an example,this study analyzed the transportation organization mode,passenger flow characteristics,and transportation connection methods and explored the applicability of the mixed passenger and freight modes of single-track urban railways.Finally,this paper proposes optimization strategies for the high-quality development of urban railways,including coordinating preliminary planning,optimizing transportation connections,improving operational efficiency,accelerating land development,and overcoming management barriers.These suggestions can provide a reference for subsequent renovation and upgrading of existing railways.
