STANDING TN 138 ISSUED 19/01/2023 has been AMENDED (*)..(*) and re-issued as below:-
APPLIES TO THE FOLLOWING ROUTE:
CRYSTAL BROOK TO BROKEN HILL
Introduction of CTC Safeworking - Crystal Brook to Gladstone & Extension and Modification of Gladstone Yard
---------------------------------------------------------------------
Upon completion of commissioning activities, the following signalling infrastructure will apply in Crystal Brook to Gladstone, Gladstone Yard and Gladstone to Caltowie Sections.
Existing ABS Train Control system from Crystal Brook Signal 6 & 6E to Gladstone new signals 23 & 23E will be converted to Centralised Train Control and be controlled from NCCW.
END CTC / START of ABS and END of ABS / START of CTC signage has been relocated from Crystal Brook 6, 6E and 5 to Gladstone 23, 23E & 24 respectively.
Crystal Brook to Gladstone Section:
--------------------------------------------
New LED Permissive Signal 381 at 38.163km.
New LED Absolute Signal 3 at 41.000km (placed on the non-preferred side due to line of sight restrictions).
Gladstone Yard Mainline:
--------------------------------
New Gladstone 7 points at 41.262km leading from main line to crossing loop.
New LED Absolute Signal 4 at 41.321km
New LED Absolute Signal 13 at 42.970km
New LED Absolute Signal l 14 at 43.386km
New LED Absolute Signal 23 at 44.070km (placed on the non-preferred side due to track clearance restrictions).
Existing Gladstone 13 points at 44.156km renamed to 20 points (leading from main line to crossing loop).
Gladstone Yard Crossing Loop:
------------------------------------
New LED Absolute Signal 4E at 41.321km (wrong sided due to track clearance restrictions).
New 15 points into Grain Terminal siding at 41.740km
Existing 15 points into Goods Loops at 42.478km renamed to 17 points
New LED Absolute Signal 11 at 42.970km
New LED Absolute Signal 12 at 43.386km
Existing 16 points into Goods Loop at 43.856km renamed to 18 points
New LED Absolute Signal 23E at 44.080km
Gladstone Yard Goods Loop:
---------------------------------
New derailer 16A points at 43.150km (west side of Horrocks Highway LX)
Existing derailer 17 points at 43.210km renamed to 16 points (east side of Horrocks Highway LX).
Gladstone to Caltowie Section:
-------------------------------------
New LED Absolute Signal 24 at 44.400km
New LED Permissive Signal 470 at 47.000km
-------------------------------------------------------------------------------
All signals will be 12V LED and will be approach lit but a manual switch is provided to bypass approach lighting for signal maintenance and testing purposes except for 381 and 470 permissive distant signals.
Points to Grain Terminal Siding (15 pts) and Goods Loop (17 & 18 pts) are equipped with HLM2 switch locks and switch stands with Yellow/White targets and are rodded to operate their associated derailer (15A, 17A & 18A respectively).
New enclosures housing control push buttons & indicators are mounted adjacent to respective turnouts. The HLM2 release required to operate the respective points will be available unless a Signalled Route has been set or Tracks over the affected points are occupied. The Network Controller’s permission is required prior to operating the release.
..(*)
Main North Rd (Horrocks Highway) level crossing upgraded to half boom gate and flashing light protection. Derailers with (*)"ATTEND TO DERAIL"(*) signage installed on Goods Loop on either side of the level crossing. Trains Travelling across Main North Road/Horrock’s Highway on the Goods Loop must stop prior to the respective attend to derail sign, operate both derails 16 and 16A to the "OFF" position. Operating either derail to the "OFF" position will activate the Level Crossing, and Train movements may proceed across the crossing once the Level Crossing boom Gates are Horizontal and Road Traffic has stopped. On completion of the Train movement, both derails need to be operated and locked in the "derail" position, which will then allow the crossing to restore for Road Traffic.
(*)ATTEND TO DERAIL sign for 16A on south side of level crossing is wrong sided due to track clearance restrictions.(*)
..(*)
Requirements for opposing Train movement protection:
Movement from 13 to 23 Signal will require 20 points reverse if 23 is at stop
Movement from 11 to 23E Signal will require 20 points normal if 23E is at stop
Movement from 14 to 4 Signal will require 7 points reverse if 4 is at stop
Movement from 12 to 4E Signal will require 7 points normal if 4E is at stop
