Figure 1
The image shows a pantograph mounted on the roof of a train. The pantograph is extended upwards and connects to overhead electrical lines. The contact strip at the top of the pantograph makes contact with the contact line, allowing the train to draw electrical power. The pantograph is a mechanical device with multiple joints and arms, designed to maintain contact with the overhead lines while the train is in motion.Electrical system schematic of a HST.
