Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures
High Voltage, EarlyView.ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.
