What is the system of overhead wires including the contact wire, feeder wires, messenger wires, and hanger which supplies power to the LRV via a pantograph?

• A. Catenary
• B. Overhead Contact System (OCS)
• C. Pantograph System
• D. Wire System

Answer: (A)

The catenary is the overhead wire system that provides electrical power to the rail vehicle via a pantograph. It isn’t just a single wire; it’s the complete suspended arrangement above the track. The contact wire is the live conductor the pantograph touches, while feeder wires supply power along the line, messenger wires give structural stiffness, and hangers hold everything in place. This combination defines the catenary system, which is why it’s the best term for describing the whole setup that powers the LRV.
