Multimodal Learning for Arcing Detection in Pantograph-Catenary Systems
CoRRThe 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.

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.
