Research on Fault Rescue Plans for Urban Rail Transit Trains
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 1
Abstract
[Objective] Once failures occur in urban rail transit, the need for assistance from other trains can significantly impact the subsequent train operation and passenger safety. Improper choices in the rescue path may also lead to secondary effects on already operating lines. Therefore, it is essential to study fault rescue plans based on rescue paths and organization. [Method] Existing procedures for fault rescue of urban rail transit trains are analyzed. Combining the actual operation time and process of train fault rescue, the process and operation time of train fault rescue are analyzed. The discussion includes the selection of rescue paths when a train fault occurs at different locations on a line. By considering the choice of the rescue train, the selection of rescue method, and the location for storing the faulty train, these aspects are combined to derive various fault rescue plans. Taking Shanghai Rail Transit Line 7 as example, the fault rescue plans are compared and summarized. [Result & Conclusion] The train fault rescue process is divided into four stages: fault handling, rescue preparation, rescue operation, and rescue completion. Based on the selection and combination of the rescue train, rescue method, and location for storing the faulty train, a comprehensive fault rescue plan for the entire Shanghai Rail Transit Line 7 is obtained. Through practical verification, this rescue plan can effectively avoid secondary delays, thereby enhancing the quality of metro services.
