Emergency Power Sharing by Using a Self‐Traction System in a Mass Rapid Transit Railway
IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.ABSTRACT Systemwide traction power outages in mass rapid transit systems (MRTSs) can cause trains to stop between stations, leading to service disruption and urgent passenger evacuation requirements. Onboard emergency self‐traction systems (ESTSs) can mitigate this risk by enabling a stranded train to reach the nearest station at low speed.

Defect Diagnosis of Rigid Catenary System Based on Pantograph Vibration Performance
ActuatorsThe condition of a catenary is significant to ensure a high current collection quality. Owing to the dynamic interaction between the pantograph and the catenary system, the vibration of the pantograph can be used to analyze the condition of the catenary ...

Load identification and fatigue evaluation via wind-induced attitude decoupling of railway catenary
Reviews on Advanced Materials Science, 2021 In strong wind area, wind vibration on key railway catenary components may lead to safety hidden danger like fatigue failures. In this work, a load identification approach was proposed by decoupling the wind-induced suspension attitude to acquire the ...

Catenaries in Riemannian surfaces
São Paulo Journal of Mathematical SciencesAbstractThe concept of catenary has been recently extended to the sphere and the hyperbolic plane by the second author (López, arXiv:2208.13694). In this work, we define catenaries on any Riemannian surface. A catenary on a surface is a critical point of the potential functional, where we calculate the potential with the intrinsic distance to a fixed ...
