A Study on the Electric Railroad Grounding System of Tunnels and Bridges

This paper presents a standard grounding scheme for bridge and tunnel areas where earthing wires cannot be easily buried. Specially, a new grounding method in which structure grounding devices are used shows good grounding effects like the earthing-wire grounding scheme. The proposed method can be a measure for equal potential in case earthing cables are disconnected.
