NETWORK RAIL has awarded Siemens a contract for signalling renewals in the Catford loop and Brixton area of south London. Valued at around £2 million, the deal will see Siemens lead through the first three stages of the GRIP process (output definition, feasibility and option selection). A contract notice explains the objectives of the project are to renew life-expired assets and improve reliability and performance. The work incorporates targeted renewal of the Herne Hill interlocking with re-control to Three Bridges Rail Operating Centre (ROC), full resignalling of the Stewart’s Lane interlocking with a similar recontrol, along with the parallel renewal of Voltaire Road switches and crossings, provision of Automatic Route Setting (ARS) and passive provision for Traffic Management.
