WebThe purpose of the case paper is to outline the Earthing and Bonding (E&B) principles and delivery on a complex subsurface metro railway project. The paper identifies how E&B is undertaken and delivered through the project life cycle. Its objectives are to illustrate the technical and programme challenges on the Crossrail project. WebThe rail running under the electrified section is called traction rail. It is properly earthed and provide path to the return current. It is not used for signaling purposes. 1.2.2 Wired Track A track provided with 25kV AC, 50Hz overhead equipment is called wired track. 1.2.3 Short Direct Connection
