IET Electrical Systems in Transportation, Volume 2023, Issue 1, 2023., 2023 Droppers and jumpers are important components of railway overhead line electrification. Their effective maintenance is critical for the railway’s safe and reliable operation; the consequences of their failure can be disproportionally serious. This paper systematically analyses the components’ failure by applying the method of failure modes and effects ...

Distribution of Currents in 2 × 25 kV Electric Railway Systems under Normal Conditions
International Transactions on Electrical Energy Systems, Volume 2023, Issue 1, 2023., 2023 This article shows a detailed analysis of the distribution of currents in 2 × 25 kV electric railway systems under normal conditions. The network equations are clearly formulated in a way that enables the presentation of a novel simplified analytical solution as well as the traditional numerical solution of the equation set.

Vulnerability Analysis of Catenary‐Bridge‐Track System
Shock and Vibration, Volume 2023, Issue 1, 2023., 2023 Continuous welded rails on bridges are extensively employed in high‐speed railways, where trains are predominantly electrically powered, and the open‐air catenary represents the weakest link in the system. Despite the widespread use of continuous welded rail on bridges for high‐speed railways, there exists a relative dearth of research on their ...

Dynamically substructured testing of railway pantograph/catenary systems [PDF]
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2018 This paper presents a methodology for testing railway pantograph/catenary systems based upon the dynamically substructured system approach for combined physical and numerical components, originally developed by Stoten and Hyde. The main advantage of the dynamically substructured system is that it can provide more stable substructured testing than ...
