Tender description

Network Rail intends to award a contract for replacement of the life-expired Frequency Division Multiplex (‘FDM’) signalling transmission system at 16 locations on the Northern section of the Brighton mainline, between Selhurst/Norwood Junction, in the North and Three Bridges station, in the South. The contract will provide Network Rail with supplies, services and works necessary to replace existing FDM systems with WestPLEX, a multi-drop signalling transmission system. This contract is for the supply and installation of the WestPLEX multi-drop signalling transmission system at a number of locations on the Brighton mainline (North). WestPLEX is a replacement system for existing FDM systems currently located on sections of the Brighton Mainline. These existing FDM systems are life-expired: they are unreliable with poor performance and require regular maintenance/repair. Their performance is resulting in regular delays and other service disruptions on the railway. Therefore, they require to be replaced. Network Rail's chosen replacement product (WestPLEX) is installed and operational on other parts of the Brighton mainline. WestPLEX is performing substantially better than the existing FDM systems. The award of this contract will result in the WestPLEX product being installed at the following locations: Relay Rooms at Three Bridges, Redhill, Stoats Nest, Purley, South and East Croydon, Selhurst and Norwood Junction and associated location cases. The contract will involve supply of the WestPLEX, system configuration, planning the installation works and installation of the system at the locations detailed above.
