Acquiring electrical energy along rail routes involves tapping potential difference produced in ground by electric railway vehicle as electrical voltage between first and second tappings

摘要

The method involves tapping the potential difference produced in the ground (3,4) by an electric railway vehicle. The potential difference is tapped using first and second tappings (6,7), whereby the potential difference is tapped as an electrical voltage between the tappings. The first tapping is located closer to the rails than the second tapping.
