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'anHuyi 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'anHuyi 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 singletrack urban railways. Finally, this paper proposes optimization strategies for the highquality 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.
