Introduction of Centralised Traffic Control between Vite Vite Loop and Maroona
----------------------------------------------------------------------------------
On Monday 10th of June 2013 at 1500 hours, the Section Authority System between Vite Vite Loop and Maroona will be abolished and replaced with Centralised Traffic Control signalling in accordance with Section 17 of TA20 ARTC Victorian Rules and Operating Procedures.

As this is the final section of ASW to be abolished, once the Network Controller is satisfied that the CTC system is operational, he is to ensure that no locomotives or track maintenance vehicles are logged onto the Section Authority Workstation. Once this has been confirmed, the Network Controller is to log-off the system and shutdown the Section Authority Workstation.

The CTC Single Line Sections will be Vite Vite Loop to Westmere Loop, Westmere Loop to Tatyoon Loop, and Tatyoon Loop to Maroona.

The control of all points and signals at Tatyoon Loop and the new Westmere Loop will be by the ARTC Section Authority Network Controller at NCCW Mile End.

The ARTC Network Controller can be contacted on Train to Base radio channel 2 or phone 08 8217 4232.

All movements shall remain in 600 mode. 1200 mode is not to be used.

VITE VITE LOOP: PRINCIPAL ALTERATIONS

The Commence and End Section Authority Territory boards and location boards will be abolished.

Signal GV1920: Will be converted from a Repeating Signal to an Automatic Signal, displays ‘Stop’, ‘Normal Speed Warning’, ‘Clear Normal Speed’ and ‘Reduce to Medium Speed’ aspects dependant on the aspect displayed on Signal VVE/26 at Vite Vite Loop.

WESTMERE LOOP:

New 3 Position signalling shall be introduced as follows:

From Melbourne to Adelaide:

Signal GV2085: New 3 Position Automatic Signal, displays ‘Stop’, ‘Normal Speed Warning’, ‘Clear Normal Speed’ and ‘Reduce to Medium Speed’ aspects dependent on the aspect of Home Signal WSM/6.

Signal WSM/6: New 3 Position Home Arrival Signal from Melbourne to Main or Loop Track. Displays ‘Stop’, ‘Low Speed’ (approach cleared to Main and loop), ‘Medium Speed Warning’, ‘Clear Medium Speed’ (to loop) or ‘Normal Speed Warning’ or ‘Clear Normal Speed’ (to Main track only) aspects dependent on the position of the points at the each end of the loop and the aspect of the next signal.

Signal WSM/30: New Home Departure Signal from Main track displays ‘Stop’ and ‘Clear Normal Speed’ aspects.

Signal WSM/32: New Home Departure Signal from Loop track displays ‘Stop’ and ‘Clear Medium Speed’ aspects.

From Adelaide to Melbourne:

Signal GV2186: New 3 Position Automatic Signal, displays ‘Stop’, ‘Normal Speed Warning’, ‘Clear Normal Speed’ and ‘Reduce to Medium Speed’ aspects dependent on the aspect of Home Signal WSM/26.

Signal WSM/26: New 3 Position Home Signal from Adelaide to Main or Loop Track. Displays ‘Stop’, ‘Low Speed’ (approach cleared to Main and loop), ‘Medium Speed Warning’ , ‘Clear Medium Speed’ (to loop) or ‘Normal Speed Warning’ or ‘Clear Normal Speed’ (to Main track only) aspects dependent on the position of the points at each end of the loop and the aspect of the next signal.

Signal WSM/10: New Home Departure Signal from Main track into the Single Line Section, displays ‘Stop’ and ‘Clear Normal Speed’ aspects.

Signal WSM/12: New Home Departure Signal from Loop track into the Single Line Section, displays ‘Stop’ and ‘Clear Medium Speed’ aspects.

Westmere Loop will be equipped with the Emergency Automatic Mode for operations during failure conditions refer TA.20 Victorian Rules and Operating procedures - Section 17 Rule 8

Points indicators in accordance with TA20 will be used to indicate the lay of points 29U and 31D, which give access to Westmere grain siding. These hand-operated points are protected by V5P key switches and interlocked with the signalling system.

FIERY CREEK BLOCK POINT: PRINCIPAL ALTERATIONS

The Block Point signage and associated location boards will be removed and Fiery Creek Block Point will no longer be deemed a safeworking location.

TATYOON LOOP: PRINCIPAL ALTERATIONS

DICE Operation shall be abolished and all associated Signalling and Signage shall be withdrawn from service.

Tatyoon Loop shall become a fully signalled CTC Crossing Loop.

New 3 Position signalling shall be introduced as follows:

From Melbourne to Adelaide:

Signal GV2277: New 3 Position Automatic Signal, displays ‘Stop’, ‘Normal Speed Warning’, ‘Clear Normal Speed’ and ‘Reduce to Medium Speed’ aspects dependant on the aspect of Home Signal TYP/6.

Signal TYP/6: New 3 Position Home Arrival Signal from Melbourne to Main or Loop Track. Displays ‘Stop’, ‘Low Speed’ (approach cleared to Main and loop), ‘Medium Speed Warning’, ‘Clear Medium Speed’ (to loop) or ‘Normal Speed Warning’ or ‘Clear Normal Speed’ (to Main track only) aspects dependent on the position of the points at each end of the loop and the aspect of the next signal.

Signal TYP/30: New Home Departure Signal from Main track displays ‘Stop’ and ‘Clear Normal Speed’ aspects.

Signal TYP/30 is located on the right hand side of the track.

Signal TYP/32: New Home Departure Signal from Loop track displays ‘Stop’ and ‘Clear Medium Speed’ aspects.

From Adelaide to Melbourne:

Signal VD2362: New Repeating Signal displays ‘Warning’ and ‘Proceed’ aspects dependent on the aspect of Home Signal TYP/26.The signal indications on this signal will alter at the next stage of commissioning.

Signal TYP/26: New 3 Position Home Arrival Signal from Melbourne to Main or Loop Track. Displays ‘Stop’, ‘Low Speed’ (approach cleared to main and loop), ‘Medium Speed Warning’, ‘Clear Medium Speed’ (to loop) or ‘Normal Speed Warning’ or ‘Clear Normal Speed’ (to main track only) aspects dependent on the position of the points at each end of the loop and the aspect of the next signal.

Signal TYP/10: New Home Departure Signal from Main track into the Single Line Section, displays ‘Stop’ and ‘Clear Normal Speed’ aspects.

Signal TYP/12: New Home Departure Signal from Loop track into the Single Line Section, displays ‘Stop’ and ‘Clear Medium Speed’ aspects.

Signal TYP/12 is located on the right hand side of the track.

Tatyoon Loop will be equipped with the Emergency Automatic Mode for operations during failure conditions. Refer TA.20 Victorian Rules and Operating procedures - Section 17 Rule 8

All new signals in this section are approach lit. As a result, vehicles which do not drop track will see 'blacked out' signals when travelling through the section. A 'blacked out' signal is to be treated as a signal at stop.

MAROONA: PRINCIPAL ALTERATIONS

Signal VD2401: Will be converted from a Repeating Signal to an Automatic Signal, displays ‘Stop’, ‘Normal Speed Warning’ and ‘Clear Normal Speed’ aspects dependant on the aspect displayed on Signal 244/6 at Maroona.

Home Signal 244/10: Displays ‘Stop’, ‘Medium Speed Warning’ (to Maroona), or ‘Clear Normal Speed’ (to Melbourne) aspects.

Home Signal 244/12 Displays ‘Stop’, ‘Medium Speed Warning’ (to Maroona), or ‘Clear Medium Speed’ (to Melbourne) aspects.

SIGNAGE:

All signage associated with ASW shall be abolished.

The text 'Start Section Authority (Melbourne line)' will be removed from the boards on signals 244/10 and 244/12 at Maroona.

Automatic Mode - Westmere Loop and Tatyoon Loop will be equipped with the Emergency Automatic Mode of operations during failure conditions - Refer to TA.20 Victorian Rules and Operating Procedures Section 17, Rule 8.
