199403 – Symons & Vaz – North Sydney Resignalling

This paper details the rationale behind the decisions governing the signalling arrangements for North Sydney and describes the system installed and the ways in which problems were successfully overcome during the development of the project.

The SRA, after investment appraisal, selected North Sydney for resignalling and track rationalisation. Subsequently a contract was awarded on the 17th of July 1992 to Westinghouse Brake & Signal Company (Australia) Ltd (WBA). The selected interlocking system was SSI allowing eventual control from the City Rail Control Centre and in the interim from a temporary panel in the Sydney Signal Box.
