A contact wire is an essential component of overhead line equipment in electric railways, providing a conductive path for electric current to power trains. It is critical for efficient and reliable train operation, requiring careful maintenance and precise installation to ensure consistent electrical contact with the pantograph of the train.

Contact Wire

Overhead Line Equipment (OLE) refers to the infrastructure used to deliver electric power to trains, trams, or trolleybuses through overhead wires. It is crucial for the operation of electric rail systems, ensuring efficient and reliable power transmission to maintain continuous movement and speed of the vehicles.

A pantograph is a mechanical linkage connected in a manner based on parallelograms, allowing for the scaling of drawings or images while maintaining their proportions. It is also used in electric trains to transfer power from overhead lines to the train's electrical systems through a spring-loaded arm that maintains contact with the wire.
