What is an "overhead line"?
An overhead line is a set of wires suspended above a railway track, used to supply electrical power to trains. These wires are connected to the train through a device called a pantograph, which collects electricity as the train moves. Overhead lines are commonly used in electric train systems, especially in areas where using a third rail is not possible. This system allows trains to run on electricity, reducing the need for fuel and helping to lower emissions while providing an efficient form of transportation.
Examples
The workers were fixing an overhead line that had fallen during the storm.
