Description

This requirement is needed to enable the successful electrification of the Core Valley Lines. E&B will play a key part in ensuring the safety of all personnel working on or near the rail, and of rail service users and customers once the line sections are energised. An effective E&B system will assist in minimising any identified Electromagnetic Compatibility (EMC) issues across an installation. Earthing and Bonding will need to be installed across the route, on all OLE assets, stations, bridges, fences and other metal assets to: - Ensure personal safety for those located on or about the railway, - Provide a safe return path for current in the event of an electrical fault, - Provide a return current path for normal load current; and - Ensure the correct operation of electrical protection systems.
