FCDM‐Net: A Feature‐Calibrated Dynamic Masking Network Based on Pre‐Trained Models for Few‐Shot Catenary Component Anomaly Detection

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel feature‐calibrated dynamic masking network (FCDM‐Net) for the unified few‐shot anomaly detection of catenary components. First, a lightweight residual adapter is integrated with a frozen visual encoder. Through a few‐shot fine‐tuning strategy, the general visual features are mapped to the specific manifold space of catenary ...

Study on the Influence of Different Dropper Models in Pantograph–Catenary System on Dropper Load Simulation

Machines
The dropper load directly influences the fatigue mechanism of the high-speed catenary system. A proper dropper model for a pantograph–catenary system can be used to accurately and efficiently investigate this phenomenon.

Multimodal Learning for Arcing Detection in Pantograph-Catenary Systems

CoRR
The pantograph-catenary interface is essential for ensuring uninterrupted and reliable power delivery in electrified rail systems. However, electrical arcing at this interface poses serious risks, including accelerated wear of contact components, degraded system performance, and potential service disruptions.

Optimal Control of Pantograph-Catenary System Based on Parametric Identification

Scientific Journal of Riga Technical University. Computer Sciences, 2011
This article continues research on the pantograph- catenary system started in the previous papers (1), (2). The main purpose of the study is to use a computer of high- speed train to optimize the pantograph-catenary system by reducing power consumption when basic parameters of pantograph and catenary (contact network) change over time randomly.

Algorithmic Energy Management in Constrained Railway Traction Networks: A Systematic Review

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This systematic review synthesises the literature on algorithmic energy management for grid‐constrained multi‐train AC railway networks, classifying the reviewed studies by algorithm family, operational scope and constraint coupling. It finds that single‐train trajectory optimisation cannot represent the coupled electrical interactions that ...
