11 SIGNALLING – DUAL ACCESS CONTROL AREAS
11.1 GENERAL
ROLLING STOCK PPP – DOUBLE DECK TRAINS
MAINTENANCE FACILITY SPECIFICATION - ATTACHMENT 7
ATTACHMENT 7 - SIGNAL FUNCTIONAL SPEC V7.DOC
The Down Relief line between signal 20D (near 46 catchpoints) at the Auburn end and
signal 221 (near 705 points) at the Granville end will be used for a variety of Operational
roles:
• Commissioning Track
• Provide access points for trains to move to and from the RailCorp network and the
PPP Co. facility
To facilitate safe and efficient management of control on this Commissioning Track section
of the Down Relief, three Access Control Areas will be established with a form of dual
access control as shown on drawings in Attachment 1. These Access Control Areas will
each be of sufficient length to receive an 8-car Set (plus stopping distance) and are located
at:
• Access Control Area 1 - Spans both sides of Clyburn Junction
• Access Control Area 2 – Auburn end of the Commissioning Track.
• Access Control Area 3 – Granville end of the Commissioning Track.
The Access Control Area will each be managed via an access control mechanism which
serves to change the mode of control of train movements within and entering / exiting each
of the areas. The mode of each Access Control Area must be capable of being changed
independently of the other two areas. Two modes of control are to be provided for each
area, namely:
• “PPP Co Control” and,
• “RailCorp Control”.
Note: Both the PPP Yard Controller and the appropriate RailCorp signaller must confirm
acceptance of change from one operating mode to the other.
11.2 TRAIN OPERATIONS IN THE ACCESS CONTROL AREAS.
The control of train operations within these Access Control Areas will vary depending on the
type of operation required. Train operations when the line is used as a “Commissioning
Track” will need to be under the control of PPP Co. whilst train operations when trains are
entering / leaving the particular Access Control Area to move from / to the RailCorp network
must be under the control of the relevant RailCorp Signal Box.
The management of the Access Control Areas must be independent of each other so that
each area can be individually switched to RailCorp or PPP Co. control.
With this flexibility the length of the Commissioning Track can be extended or reduced
depending on the need for other trains to enter / exit the Down Relief and move from / to the
RailCorp network.
