TN 589 / 2014 issued on 14/03/2014 is replaced by the following Train Notice:


Train Notice applicable to the operation of signalling and Train Control Functions between Maroona and Pyrenees including operating protocols (Yard instructions) for Maroona.

MAROONA

The points and signals at Maroona are operated by the ARTC South West Network Controller in Adelaide.

Maroona operates as a Train Order Terminal Station for movements to and from the Portland Line and a CTC unattended crossing location.

Safe working system is CTC - Centralised Traffic Control between Pyrenees Loop and Maroona

A release is provided for control of the Departure signals between Maroona and Pyrenees and the ARTC South West Network Controller shall give the release to the ARTC North West Network Controller to allow for the departure signals at Pyrenees Loop to be cleared for a rail movement to proceed from Pyrenees Loop.

The ARTC North West Network Controller shall give the release to the ARTC South West Network Controller for rail movements to proceed from Maroona towards Pyrenees Loop.

Should the Home Departure signals at Pyrenees Loop fail, the authority to pass these signals will be a CTC Home Departure Caution Order issued by the ARTC South West Network Controller.

The driver of a Portland line rail movement shall not proceed beyond signal 244/10 or 244/12 unless in possession of the appropriate Train Order (Portland Line)

Signal 244/12 also has a illuminated route indicator with shows M Melbourne or P Portland

Up Automatic Signal V2484 between Pyrenees Loop and Maroona is powered by batteries, which are charged by solar panels. During the period that no movements are within the approach circuit of this signal, the top light will be extinguished however the marker light will continue to be lit.

Immediately a movement enters the approach circuit for this signal it will then be lit and will display the applicable aspect for the track ahead. The approach circuit is immediately an up movement passes down Automatic Signal V2635 at Ararat (1500 metres from the signal).

In the event that a fault is detected in the lighting of this signal, the applicable departure signals leading into the single line section in which the signals are located will be held at ‘Stop’.

In addition, an ‘Auto Power Off’ or ‘Lamp Fail’ alarm will be displayed on the Phoenix CTC system alerting the ARTC Network Train Controller of the failure.

The Train Controller shall issue the appropriate authority to the Driver to pass the affected Departure Signal at stop and also advise the Driver of the circumstance regarding the failure alarm.

The Train Controller shall also report the failure to the applicable Signal Maintenance Technician so that the fault may be rectified.

Point Stand Indications
------------------------------
The points from the loop line to the Goods Siding at both ends of the yard are equipped with a T21 point machine. Point Stand Indicators are placed on the point machines to indicate to the Driver of approaching trains the position of the points as follows:

Yellow Circle: Indicates to movements proceeding in both directions that the points are set for the loop line.

White Square: Indicates to movements proceeding in both directions that the points are set for the Goods Siding.

Should the Driver of a movement observe the Point Stand Indicator displaying a white square the Train Controller shall be immediately advised. The Movement shall be brought to a stand at the points and the Driver shall ensure that the points are set and secure for the movement prior to passing over them.

Goods Siding Point Locking
-----------------------------
V5PSW key switches are located adjacent to the Goods Siding points at either end of the yard and are electrically connected to the Train Controllers operating system in Adelaide and provide electric locking of the points.

The key switches have 3 positions as follows:
Cancel: Cancels the release command after the points have been set for the Loop line.
Centre: Allows the key to be inserted or removed from the Key Switch.
Accept: Accepts the release command initiated by the Train Controller.

Three indicator lights are provided at each Key Switch; the lights are labelled and indicate the status of the release or points as follows:
Points Locked: Indicates that the Points are set and secured and cannot be operated.

Release Available: Indicates that the Train Controller has provided a Release Command for acceptance by the Driver required to operate the points.

Points Free: Indicates that the points are available for operation.

Location of Derail Devices
------------------------------------
A rodded Hayes Wheel Crowder and Derail is located as follows:

Melbourne end: The Fouling point on No 3 and 4 tracks (rodded to the T21 point machine operating the points to the siding).The Clearance point is marked by a painted white sleeper on both 3 and 4 roads.

Adelaide end: The Fouling point on No 3 track (rodded to the T21 point machine operating the points to the siding). The Clearance point is marked by a painted white sleeper on 3 and 4 roads.

Train Operations at Maroona Goods Siding
--------------------------------------------
Prior to a movement arriving at Maroona Yard the Train Crew shall confirm with the ARTC Network Controller that the movement is required to work within the Maroona yard.

On entering the Loop Track, the Driver of the movement shall bring the train to a stand at the points and:
1.*Contact the ARTC Network Controller and request a release on the Points,
2.*Observe that the ‘Release Available’ light is displayed
3.*Insert the key and turn it to the ‘Release’ position.
4.*Observe that the ‘Points Free’ light is displayed.
5.*Return the key switch to the ‘Centre’ position, withdraw it and unlock the ‘Hand Throw’ Lever on the Point Machine.
6.*Operate the T21 point machine to the required position for the movement.

Immediately the movement is clear of the main line the points are to be restored to the ‘Normal’ position and the ‘Hand Throw’ lever locked again.

The Driver shall insert the 5VPSW key in the key switch and operate it to the ‘Cancel’ position and advise the Train Controller.

Issue of Train Orders to the Portland Line
------------------------------------------------
Drivers of Portland Line Movements shall bring the train to a stand at Maroona to receive a Train Order from the ARTC North West Network Controller.

Should a Portland Line Rail movement be standing at Pyrenees Loop waiting to depart, the ARTC Network Controller may issue a Train Order to the Driver of the Portland Line bound rail service provided that;

1. There are no movements operating between Maroona and Glen Thompson Loop
2. There has been no Train Order issued towards Maroona
3. There are no Maintenance activities in operation which would prevent a Train Order being issued.

The ARTC Network Controller may issue a Train Order for the Rail movement to proceed beyond Maroona towards Portland. The Train Order TEXT must commence with the following text:

Proceed from Maroona to.. .
---------------------------------
The ARTC North West Network Controller will then advise the ARTC South West Network Controller when a Train Order has been issued for a movement to depart towards the Portland Line.

The ARTC South West Network Controller must not clear a signal for a rail movement to depart towards the Portland Line without first being advised that a Train Order has been issued for the movement.
