9.3.2 SIGNALLING INTERLOCKINGS
9.3.2.1 Stages 1 & 2
The new PPP Co. Signalling system will need to interface with the existing Relay
Interlocking at Auburn and SSI Interlocking at Granville as noted on the attached control
area drawings (see attachment 1).
Due to the age and condition of the Auburn interlocking and signal box control panel the
changes have been kept to an absolute minimum. Alterations to the signalling for the
modified track layout connecting to the PPP Co. Yard areas have been designed to allow
the reuse of existing control panel switches.
In addition the signalling layout has been designed to eliminate / minimise changes to the
Granville interlocking and associated control system.
Note: The Access Control Areas must be designed to ensure minimum changes to the
RailCorp signalling systems at both Auburn and Granville.
