PAN-tuh-graf
Definition
An apparatus mounted on the roof of an electric train or locomotive to collect electric current from overhead lines.
Etymology
Derived from the Greek words 'pas' (all) and 'grapho' (to write), it originally referred to an instrument used for copying maps or drawings. It was later adapted to describe the sliding, parallelogram-shaped frame used to collect electricity from overhead lines due to its mechanical resemblance to the drawing tool.
