200107 – Stepniewski – Blacktown’s VDU Signalling Control System “SigView”

Alstom’s VDU Control System, called SigView, was successfully commissioned at Blacktown, in two stages as part of the Blacktown Resignalling Project:
– Stage l: control of Blacktown and Quakers Hill in December 1999.
– Stage 2: control of Richmond Line and Quakers Hill in March 2000.

The Blacktown SigView was the first VDU based signalling control system to be commissioned in the Sydney Metropolitan area. It controls four local SS1 interlockings and remotely controls four relay based interlockings on the Richmond Line. Of these relay based interlockings, three are nx (entrancelexit) type and one is OCS type. For Stage 1, it controlled the existing unit lever
interlocking at Quakers Hill, for Stage 2 Quakers Hill was converted to SSI. SigView provides a seamless and consistent operator interface to all these various types of interlockings.

The Blacktown SigView features entrance/exit route setting control, train tracking, sleeving, a
notepad facility, alarms and logging/archiving facilities.

The system has been in operation for 18 months now and has proved to be reliable.
