Overhead Line: The Invisible Backbone of the Railway
Overhead Line: The Invisible Backbone of the Railway The overhead line – often viewed as an invisible but essential element of railway infrastructure – is the central component of an electrically operated rail system. It supplies trains with the necessary energy to continue their journey on the tracks. But what exactly lies behind the technology and challenges associated with the installation and operation of overhead lines? What is an Overhead Line? The overhead line, also referred to as "catenary" or "overhead line system," is the system that transfers electrical energy from the overhead wire to the train. It consists of a variety of components that ensure the electrical energy reaches the trains from the power grid. These include, among others: - Contact Wire (Overhead Wire): The wire along which trains travel and from which they draw electrical energy. - Masts and Supports: These hold the contact wire at the correct height and position it above the tracks. -...
