A simplified approach to determine aerodynamic damping of railway overheads [PDF]
, 2011 The railway overhead (or catenary) is the system of cables responsible for providing electric current to the train. This system has been reported as wind-sensitive (Scanlon et al., 2000), and particularly to the occurrence of galloping phenomena ...

A modelling approach for railway overhead line equipment asset management [PDF]
, 2017 The Overhead Line Equipment (OLE) is a critical sub-system of the 25kV AC overhead railway electrification system. If OLE asset management strategies can be evaluated using a whole lifecycle cost analysis that considers degradation processes and ...

Evolution of the electrical contact of dynamic pantograph–catenary system [PDF]
Journal of Modern Transportation, 2016 A good contact between the pantograph and catenary is critically important for the working reliability of electric trains, while the basic understanding on the electrical contact evolution during the pantograph–catenary system working is still ambiguous so far.
