Availability Evaluation of Overhead Contact Lines Based on a Stochastic Colored Petri Nets Model
IET Electrical Systems in Transportation, Volume 2025, Issue 1, 2025.Due to their nonbackup characteristics and constant exposure to outdoor conditions, the performance of overhead contact lines (OCLs) will gradually degrade over time and further result in equipment defects or frequent failures. These issues significantly impact system availability and incur substantial repair costs.

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.In this manuscript, we proposed physics‐informed surrogate model, called FENet, for the first time to solve the interaction of pantograph‐catenary system. In recent years, much progress has been achieved in PCS modelling solutions. Existing solutions, however, suffer from two significant limitations: 1) An urgent concern arises regarding the ...

Risk Mapping for Daily High‐Speed Railway Disturbances Based on Operation Loss
Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.Confronted with the disturbances arising from various risk events, it is crucial to accurately measure the severity of risks in the dispatching section for efficient train operation and transportation management of a high‐speed railway (HSR). This paper proposes a risk mapping method for daily HSR disturbances based on a self‐formulated operation loss ...
