Which one is more critical? tension loss in contact wire or messenger (catenary) cable

The electrification of a fleet involves either a third rail or an overhead catenary system typically. Achieving appropriate current collection in a high-speed train needs the contact wire geometry within defined limits. This aim is usually achieved by supporting the contact wire from a second wire known as the messenger wire (in the US & Canada) or catenary (in…

Amazing nonlinear behaviour of droppers in the catenary system

Estimated time for reading: 8 min Overhead Catenary Systems (OCS) are the most common practice for supplying electricity to electric trains. Provision of continues connection between pantograph and contact wire with the added necessity for low electrical wear and mechanical wear of collector strip is amongst the main challenges for engineers and researchers alike regarding…
