Overhead Catenary System

Definition

An overhead catenary system refers to all components related to the electrification of light rail construction, including but not limited to the catenary wire.

Purpose

The overhead catenary system provides the necessary electrical infrastructure to power light rail and trolley systems. It ensures a consistent and reliable power supply to electric trains and trams, enabling efficient and eco-friendly public transportation.

Examples of Use

• Light Rail Systems: Electrifying urban rail networks to power trains using overhead catenary systems.
• Trolleybuses: Providing power to trolleybuses through overhead wires.
• Commuter Trains: Electrifying regional and commuter rail lines for faster and cleaner transit.

Related Terms

• Catenary Wire: The overhead wire from which the contact wire is suspended, used to supply electricity to trains.
• Pantograph: The apparatus mounted on the roof of electric trains to collect current from the overhead catenary system.
• Substation: Facilities that convert and distribute electrical power for use by the overhead catenary system.

Notes

• Maintenance: Regular maintenance is required to ensure the reliability and safety of the overhead catenary system.
• Infrastructure Investment: Significant investment in infrastructure is needed for the installation and upkeep of these systems.
