Overhead line equipment consists of the wires, masts, insulators, and tensioning devices suspended above the track. It delivers high-voltage alternating or direct current to electric locomotives and multiple units via a roof-mounted pantograph. Maintenance crews monitor it closely for proper tension and alignment to prevent wire snagging.
