1.New double ended crossover points No.5U and 5D will be provided at the junction of the East and West lines.
These points are fitted with Vossloh Cogifer point machines and are rated at a speed of 80kp/h for the diverging move.
The point machine is interlocked with the Signalling System so that when the selector switch is placed to the hand operating position, the signals protecting the points will be secured at stop.
OPERATION OF POWER-OPERATED POINTS
Nos. 5 points at West Wodonga which are operated by the Network Operations Controller Main South C at Junee, are fitted with Vossloh Cogifer electric point machines.
If these points fail to operate correctly, the Network Operations Controller must try to restore the points to their previous position to allow trains to continue running. However, if it is necessary to alter the route, the points may be manually operated.
The Vossloh Cogifer point machines are provided with a selector switch and hand throw lever which, when not being operated manually, are secured by V5PSW locks.
MANUAL OPERATION OF VOSSLOH COGIFER POINTS
Vossloh Cogifer point machines are provided with a long hand throw lever to allow the points to be operated manually to either normal or reverse when necessary.
To manually operate the points:-
- Unlock the V5PSW padlock on the Selector Switch.
- Pull out the locking pin from the selector switch.
- Move the Selector switch to the hand position.
- Unlock and remove the lock from the hand throw lever.
- Remove the locking pins from both sides of the hand throw lever.
- Move the hand throw lever to operate the points to the required position.
- Make sure the switch blade is hard up against the stock rail.
To restore the points from HAND to MOTOR:
- Undo and remove the V5PSW lock from the selector switch and manual operating handle where applicable.
- Move the selector switch from HAND to MOTOR.
- Ask the Network Operations Controller to test the points and confirm they are operating correctly.
- Reapply the V5PSW lock to the lever catch and the selector switch in the appropriate position.
The signals maintenance representative must be promptly advised of the circumstances.
Note:- Depending on the position of the points, the hand throw lever may need to be switched to the opposite side to engage the clutch to operate the points manually.
Point clips will be provided in steel boxes locked with a V5PSW padlock adjacent to each point machine.
The modifications involve some track reconfiguration, re-signalling and interlocking/operational control changes at Wodonga.

1. METHODS AND PROCEDURES FOR THE OPERATION OF RAIL TRAFFIC
1.1 Wodonga Coal Sidings
Wodonga Coal Sidings Signalbox must be switched in and attended by qualified Signallers during the commissioning period.
Signals applicable for rail movements to Albury will remain operational and will be operated by the Signaller at Wodonga Coal Sidings under the direction of the Network Operations Controller Main South C at Junee.
Home Signals 10 & 11 will be fixed at stop and rail movements will require a Train Authority to pass these signals at the stop position to proceed to Chiltern.
Signals 94, 82, 18, 8, 3, old WOD/8, WOD/6, WOD/U6, WOD/4, WOD/U4, WOD/2, ES2937, EES2937, WOD/18, WOD/6 and new WOD/8, ES9721, ES9454, ES9332, ES9331,ES9209 and ES9080 will be extinguished and crossed out of use.
Train Authority working will be in force between Coal Sidings Signals No. 10 & 11 and Chiltern Loop Signals CLT/6 & CLT/U6.
1.2 Chiltern Loop
Chiltern Loop will be available for the crossing of rail movements and follow on rail movements.
A Signaller will be located at Chiltern Loop to issue Train Authorities under directions of the Operations Coordinator, and if necessary, operate point machines manually.
All signals at Chiltern Loop will be lit and will operate with the exception of CLT/6 & CLT/U6. These latter signals will be fixed at STOP and will require a Train Authority for rail movements to pass them at STOP to proceed to Wodonga Coal Sidings.
Train Authority working will be in force between Chiltern Loop Signal CLT/6 CLT/U6 and Wodonga Coal Sidings Signals 10 & 11.
1.3 Management of Rail Movements
Train control management is under the direction of the ARTC Main South C Network Operations Controller.
An Operations Coordinator will be located at West Wodonga and will obtain advice from the ARTC Network Operations Controller Main South regarding the priority and precedence of rail movements between Chiltern Loop and Wodonga Coal Sidings.
The Operations Coordinator must liaise with the Signallers at Wodonga Coal Sidings and Chiltern Loop regarding the priority of rail movements over this section.
The authority of the Operations Coordinator must be obtained prior to the issue of each Train Authority.
1.4 Safeworking of Rail Movements
Signalbox locations will be established at Wodonga Coal Sidings and Chiltern Loop.
During the period that re-signalling works are being undertaken, all rail movements between Chiltern Loop and Wodonga Coal sidings will operate by means of Train Authorities.
In simple terms, Train Authority Working operates on the basis of an 'Absolute Block' principle where the Signaller in advance will issue a Train Authority to the Signaller in the rear for a train to approach. This will be done by telephone communication and is detailed fully in this Train Notice.
Before the issue of a Train Authority, the Single Line Section between Wodonga Coal Sidings and Chiltern Loop must be clear of rail movements. Prior to the issue of a Train Authority, the previous Train Authority issued for a rail movement must be collected by the relevant Signaller and provided the rail movement has arrived complete and in clear at either Wodonga Coal Sidings or Chiltern Loop, cancelled by writing the words 'CANCELLED' together with the time, date and signature of the cancelling Signaller.
For a movement to proceed from Wodonga Coal Sidings to Chiltern Loop, the Signaller at Chiltern Loop will dictate a Train Authority to the Signaller at Wodonga Coal Sidings who must record the Authority, read back the Authority, and then deliver the Train Authority to the crew of the rail movement.
For a movement to proceed from Chiltern Loop to Wodonga Coal Sidings, the Signaller at Wodonga Coal Sidings will dictate a Train Authority to the Signaller at Chiltern Loop who must record the Authority, read back the Authority, and then deliver the Train Authority to the Driver of the rail movement.
UNDER NO CIRCUMSTANCES IS A TRAIN AUTHORITY TO BE PREPARED IN ANTICIPATION OF A RAIL MOVEMENT, BUT IN ALL INSTANCES, MUST ONLY BE ISSUED WHEN THE ISSUING SIGNALLER HAS PREPARED AND DICTATED THE TRAIN ATHORITY TO THE RECEIVING SIGNALLER WHO WILL COMPILE THE TRAIN AUTHORITY AS DICTATED BY THE ISSUING SIGNALLER.
There will be no requirement for the Driver of the rail movement to verify the Train Authority, however, the Driver must sign the butt of the form when receiving and after reviewing the Train Authority.
Should it become necessary for a Signaller to cancel a Train Authority after its’ issue, this can only be done on the authority of the Operations Coordinator.
From a management perspective, the Network Operations Controller remains in charge of all rail operations over the commissioning area, however, there is a requirement for a defined communications protocol that ensures that rail movements operate safely through the affected area.
The Signaller at Wodonga Coal Sidings will be responsible for the issue of train authorities to the Signaller at Chiltern Loop for trains to approach, and the receipt of train authorities from the Signaller at Chiltern Loop for trains to proceed to Chiltern Loop.
1.5 Road/Rail Journeys
The operator of a Road/Rail vehicle required to operate between Chiltern Loop and Wodonga Coal Sidings must obtain permission from the Signaller at either Chiltern Loop or Wodonga Coal Sidings. The Signaller concerned must communicate with the Operations Coordinator as to whether the necessary permission may be granted. The Operations Coordinator must confer with the ARTC Network Operations Controller Main South C as to whether the permission requested may be granted and notify the Signallers accordingly.
Details of the permission and time granted must be entered in the Train Register Book.
1.6 Level Crossings
The Automatic Electronic Level Crossing protection equipment at Cochranes Road (Old Barnawartha Road), Melrose Drive, Kelly Street, Station Entrance, High Street, Hovell Street and Osburn Street will not operate normally during the commissioning period. Level Crossing keepers will be in attendance to manually operate the electronic protection equipment by means of the test switch provided at each level crossing.
The level crossing keeper will be provided with flags, lamps, safety equipment and communications equipment that allow communications with the Signallers at Wodonga Coal Sidings and Chiltern Loop regarding the movement of rail traffic.
Rail movements must approach non-operational level crossings at a speed that will allow the train to be stopped until an 'All Clear' hand signal is received from the crossing keeper. The Level Crossing keeper must be on the alert to operate the test switch in sufficient time to prevent delay to rail movements. When the level crossing equipment is operating correctly for a rail movement, the crossing keeper must display the 'All Right' hand signal to the Driver of the approaching rail movement.
A communications structure will be established that will allow all Signallers, Level Crossing keepers and the Operations Coordinator, to communicate effectively with each other.
The following communications systems will be provided:
2.1 Operations Coordinator:
Telephone with hands free to Network Operations Controller Main South C at Junee.
Mobile telephone with predial of all Signallers and Network Operations Controller.
Local radio with single channel to communicate with all Signallers.
Local radio with single channel to communicate with other Signallers, Level Crossing keepers and the Operations Coordinator.
2.3 Operations Coordinator, ARTC Network Operations Controller Main South Junee and Signallers:
The Operations Coordinator will liaise with the Network Operations Controller Main South C at Junee via the telephone system.
The Operations Coordinator is also provided with a mobile telephone as alternative communications.
The Operations Coordinator will liaise with the Signallers and other safeworkers via the local radio system.
At the commencement of each shift, prior to any works being undertaken, the Operations Coordinator shall contact the Network Operations Controller Main South C at Junee and establish the proposed rail movements for the day.
2.4 Tester in Charge and Operations Coordinator
The Tester in Charge and the Operations Coordinator shall meet and come to a full understanding of the works to be performed. The meeting shall be minuted and there shall be a full understanding of the conditions under which the works shall be undertaken and the methods to be used for movements during that period.
Should there be a variance to the works, the Tester in Charge shall not allow the varied works to be undertaken without first liaising with the Operations Coordinator and ensuring that the variance is understood and noted in the minutes.
The Operations Coordinator will then meet with the incoming Signallers and detail the activities for the day.
3. TESTING OF POINTS & SIGNALS
No testing of points and signalling shall be undertaken during the period that a rail movement is approaching or traversing the work site.
The Tester in Charge shall advise the Operations Coordinator of any works that are to be undertaken that may affect the safety of a rail movement.
After the interlocking control system is operating to the satisfaction of the Tester in Charge, the TIC shall arrange with the Operations Coordinator for the signals fixed at stop at the start of the commissioning to be changed over to operating from the interlocking system but vitally blocked. This shall not be done when there are any rail movements approaching or traversing the worksite. The vital blocking of these signals shall not be lifted for testing purposes without the authorisation of the Operations Coordinator.
3.1 Track Force Operations
Track Force operations consisting of track and signal works will take place through the area of the signal commissioning. Under no circumstances are any track force works to commence unless a qualified Protection Officer/Track Protection Coordinator first makes an assessment and provides the appropriate track force protection.
The qualified Protection Officer/Track Protection Coordinator must maintain contact wit the Operations Coordinator at all times.
The Operations Coordinator shall maintain an Operational Event Log, which shall be completed prior to each movement and also detail any relevant information that is applicable to the safe operation of movements.
The Operations Coordinator will also maintain all instructions and events issued by the Network Operation Controller Main South on a separate log.
The Signallers will complete a point log prior to each movement as part of the route confirmation.
The point log consists of a diagrammatic lay out of the location on which the safeworker will enter the train details of each movement, and simply endorse on the drawing the lay of each set of points and initial confirmation of the route.
Signallers at Chiltern Loop and Coal Sidings Signalbox will enter details of all rail movements in the Train Register Book provided for each movement or activity.
