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.

The steerability of railway vehicles
Transport Problems, 2007 The term steerability is widely used in the motion theory of wheel andtrack-laying machines, water and air vehicles, spacecraft. Steerability is a property of a transport machine to submit to the managing influence. Steerability of the machine is defined by its reaction to managing influence on the part of managing in the form ofchanging travelling ...
