What is a "pantograph"?
A pantograph is a device used on electric trains to collect electricity from overhead power lines. It is a lightweight, hinged structure that extends upward from the train to make contact with the wires above. The pantograph slides along the power lines, allowing the train to draw the electricity needed to run the motor. Pantographs are commonly found on high-speed trains or electric locomotives, where they provide a continuous power source while the train is in motion. They are designed to be flexible and can automatically adjust to different heights of power lines.
