Introduction

Track Warrant Control (TWC) is an operating system where occupation of the main line is controlled by instructions issued from Train Control.

  • TWC areas are specified in the Rail Operating Procedures, Section 10.
  • The beginning of each TWC area will be defined by a Notice Board - TWC BEGINS
  • The end of each TWC area will be defined by a notice board, either TWC ENDS or CTC BEGINS.
  • TWC areas are arranged and equipped with Interlocked Stations, Warrant Stations and Sidings.


400 Definitions

(a) Intermediate Board
a notice board provided between stations or sidings to identify a location which may be used to designate a limit for a track warrant. The locations of Intermediate Boards are shown on S&I Diagrams and listed in the Rail Operating Procedures.

Figure 401

(b) Siding
Siding points on the mainline in TWC areas are operated by a hand lever secured by a TW Lever Lock and AS padlock unless otherwise specified in the Rail Operating Procedures. The locations of Sidings are shown on S&I diagrams and listed in the Rail Operating Procedures.

Except where permitted in Track Safety Rule 914 (MTMV) main line siding points must not be unlocked until the appropriate track warrant has been obtained.

(c) Station Warning Board
a notice board, provided in the absence of an intermediate or distant signal, to warn of the approach to station limits at a Warrant Station or the end of TWC territory.

Below the board will be the name of the station.

Fig 402 Fig 403



(d) Station Limits
Includes all lines within the Arrival, Home, or where provided, Outer Home signals. Where fixed signals are not provided, station limits include all lines within the first facing points or points indicator met approaching the station on the main line from either direction unless defined by notice boards.

(e) Warrant Station

A non-Interlocked station provided for the crossing of trains, or the junction of two main lines. The approaches to Warrant Stations from each direction will be marked with a Station Warning Board or Intermediate signal.

Warrant Stations are equipped with either motor or hand points.

Except where permitted in Track Safety Rule 914 (MTMV) main line hand points must not be unlocked until the appropriate track warrant has been obtained.



Diagram of a Warrant Station Figure 404 (Arrival Signals may be substituted with Facing Points Indicators)



(f) Interlocked Station
A station where control of points and fixed signals is centralised and arranged to prevent conflicting movements. The operation of the points and signals is manually controlled in addition to being controlled by track circuits

Interlocked stations are protected by Home signals or where provided Outer Home signals.

(g) Track Warrant
An authority issued by Train Control defining limits and other instructions for the occupation of the mainline.

(h) Hi-Rail Vehicle
Reference to Hi-Rail vehicles in these rules includes motor trolleys and material trolleys.

(i) Marker Posts

  • Are provided between the Station Warning Board and the Arrival Signal or Facing Points Indicator at some Warrant Stations as a train handling aid.
  • Indicates the start of track circuiting that may or may not change the aspect displayed on the Arrival Signal or Facing Points Indicator
  • Marker Post locations are notified in the ROR&P Local instructions

401 Operating in a Track Warrant Control Area

(a) A train, shunting movement, Hi-Rail vehicle or MTMV must not enter upon or foul any part of the main line without the authority of a track warrant. This includes the main line within station limits.

Exception:
MTMV and Hi-Rail vehicles operating within a work area protected by Compulsory Stop Boards.

The Addressee must understand and comply with the limits of the Track Warrant.

(b) The authority of a track warrant will apply to the main line only.

(c) Main line points operated by a hand lever must not be unlocked until a track warrant to occupy or work on that part of the main line is obtained.

(d) A track warrant may be issued to allow work on or alongside the main line without other protection. A track warrant issued for other than trains must be addressed to the Person responsible for safe working.

(e) A track warrant may contain other instructions with which the addressee must understand and comply.

(f) Separate track warrants must be issued to and from a station at which a train is to cross or overtake another train.



Exception:

A "through" warrant may be issued to the second train when:
The first train is:

  • At the station where the crossing is to take place, and
  • Waiting in clear of the main line.

If the first train is occupying the loop:

  • The second train must be advised that the first train is "sidetracked at".


(g) The Addressee reporting limits clear of a track warrant or portion of the limits clear, must only do so when it has been confirmed that:

  • main line hand points are locked in the normal position,
  • the train is complete,
  • the whole train has cleared the “limits” being released.
  • all Hi-Rail vehicles and MTMV’s have cleared the “limits” being released.


402 Warrant Instructions

(a) Proceed
When a track warrant authorises a movement to "proceed" the movement must proceed in the direction specified except when verbally authorised by Train Control for shunting at a station or siding. Train Control must not give such authority for any part of the line where another movement or work has been authorised.

Level Crossing to be protected.

Exception:
Hi-Rail vehicles may set back up to 100 metres within the limits of the track warrant.

Note:
It is not permissible to set back into territory where the limits have been reported clear.



(b) Work Between
When a track warrant authorises a movement to "work between" the movement may work in either direction between the locations specified. The movement must not enter a station or siding which is a limit of the track warrant unless authorised to do so.

(c) Conditional - All cases



Note:

It is not permissible for a train to be issued with a conditional track warrant conditional upon the arrival or departure of a Hi-Rail Vehicle or MTMV.

A track warrant which specifies that a movement or work is authorised "after" a movement, may only be issued when:

  • the addressee is at the location at which the train is to arrive at or depart from,
  • the movement after which the movement is to take place has been authorised to proceed in one direction only, and
  • is due at that location within the next 15 minutes.

(d) Conditional – After arrival of

When the movement is to be carried out after arrival of another movement the addressee must ensure the movement specified has in fact arrived, before carrying out the movement or work authorised. (e) Conditional – After departure of

When the movement is to be carried out after departure of a train, the addressee must ensure that the departing train has cleared the area far enough for the movement or work to be safely performed.

(f) Time

If a time by which the main line is to be clear is shown in the track warrant, the Addressee must clear the limits by the time specified unless another track warrant has been obtained. Uncontrolled Copy



403 Occupying Same Limits

(a) Single Track Warrant – Multiple Activities

When “Multiple Activities” are authorised on a single track warrant (i.e. MTMV’s, Hi-Rail Vehicles and /or Work Trains), Work Site

A single track warrant may be issued to the Person in Charge of the work site, who in turn will be responsible for safe working and advising the number of the track warrant that is held together with other particulars on the warrant to the Person in Charge of the MTMV’s, Hi-Rail Vehicles and/or the Locomotive Engineer(s) of the Work Train/s.

Two or more Hi-rail vehicles travelling together

Where two or more trolleys or hi-rail vehicles are travelling together, a single track warrant may be issued to the Person in Charge, who in turn will be responsible for safe working and advising the number of the track warrant that is held together with the particulars on the track warrant to the other hi-rail vehicles drivers.

(b) Multiple Track Warrants – Common Limits

A track warrant must not be issued for any portion of the line for which another track warrant is still in effect except in the following circumstances:

  • That portion of the line which is common to both track warrants is within the "work between" limits of each warrant. The respective track warrants must advise the addressees of each other's presence on the same part of the line, and if necessary contain specific instructions for safe working.
  • A movement is following another which is authorised to proceed in one direction only and either:

    - the movement in front has reported limits clear of a station, siding or Intermediate Board beyond any location to which the following movement is being authorised; or

    - the movement in front has reported limits clear of a station in advance and the following movement is authorised up to or into that station; or

    - the movement in front has berthed in clear on the main at a station in advance and the following movement is authorised up to or into the loop at that station.
  • The second track warrant authorised a movement "after the arrival" of a movement whose track warrant is still in effect.
  • The second track warrant authorises shunting or other work on or foul of the main line "after the departure" of a movement whose track warrant is still in effect.


404 Limits of a Track Warrant

(a) The limits of a track warrant will be designated by specifying Stations, Sidings, Intermediate Boards, Signals, Points Indicators, Points or Track Metrage Pegs.

Track Metrage Pegs and the rear of Signals and Points Indicators must not be used to designate the limit to which a train is authorised to "proceed" but can be used to authorise a train to "work between". Metrages that are regularly used by maintenance staff maybe used to designate limits of track warrants that are issued to these personnel.

(b) The authority of a track warrant which commences at a station or siding will extend from:

At an Interlocked Station

The last main line to loop points met when leaving the station, or if there is no loop the last main line points. When the movement over these points is controlled by a signal the authority will extend from that signal.

At a Warrant Station

The last main line to loop points met when leaving the station, or if there is no loop, the last main line points. When these points are equipped with a Points Indicator then the authority will extend from the Points Indicator.

At a Siding

The last main line points met leaving the siding

At a TWC Begins Board

The TWC Begins Board.

(c) The authority of a track warrant which terminates at a station or siding will extend to: At a Station

Station limits at the entrance to the station.

At a Siding

The first main line points met approaching the siding.

Note

When the track warrant instructs the movement to enter the main.

the authority will extend to the last main line to loop points, or if there is no loop, to the last main line points. When these points are equipped with a signal or points indicator which applies to the movement the authority will end at that signal or points indicator. When the track warrant instructs the movement to enter the loop or siding.

the authority will extend to and include the first facing points which give access to the loop or siding.

At a TWC Ends Board

The TWC Ends Board

(d) The movement must not stand foul of points when these are the limits of the track warrant.



405 Clearing Controlled Signals

A controlled signal must not be set at "Proceed" for any movement which requires the authority of a track warrant until the track warrant has been issued.



406 Fouling the Loop in TWC Territory

(a) A loop in TWC Territory may only be fouled or obstructed once verbal permission has been granted by Train Control.

(b) Any authorised fouling of the loop other than authorised by a track warrant must be endorsed on the Train Control diagram.

(c) When a loop is known to be occupied at the time a track warrant is issued, passing trains will be advised of this in clause 12 of track warrants.

(d) If a track warrant for a through or berthing movement has already been issued:

Train Control must:

  • verbally advise berthing trains already authorised to enter the same loop,
  • verbally advise passing trains,
  • endorse the Train Control graph with the train numbers advised, after the Locomotive Engineers acknowledgement,
  • grant permission to occupy the loop. Locomotive Engineers must:
  • contact the person who has been verbally authorised to occupy the loop and reach a clear understanding in how the conflicting movements will be safely performed. If radio contact cannot be established:
  • entry into the station may occur after visual observation indicates it i
  • request Train Control to establish and advise the whereabouts of the opposing train.


407 Issuing Track Warrants

(a) Train Control must:

    • Enter the relevant details on a Mis 87. • Transmit the instructions to the addressee. (b) The addressee must: • Complete the Mis 88, with the exact instructions transmitted. • If in any doubt, seek clarification of the track warrant limits. • Read back the instructions to Train Control. (c) Train Control must check the read back and either: • confirm its completeness by the words "that is correct", followed by the time, or • correct the read back with the Addressee. Once correctly read back this is confirmed by the words "that is correct", followed by the time. (d) Each person will endorse this time in the space provided in the track warrant which will then be in effect; the time being repeated back to Train Control. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 418 - 408 Relaying Track Warrants Should Train Control not have direct communication with the addressee the track warrant particulars may be relayed through another person qualified in the operation of Track Warrant Control, Relaying Person must then: • Correctly repeat the particulars back to Train Control, before relaying the track warrant to the addressee. The Addressee must then: • Read back correctly to the relaying person. The Relaying Person must then: • Confirm by the words "that is correct", followed by the time. Both these persons must then: • Endorse this time in the space provided in the track warrant which will then be in effect. The Relaying Person must then: • Advise Train Control that the track warrant has been relayed to the addressee and the time the correct repeat was obtained. • Write “Relayed” across the face of the warrant and forward it to the Manager, Codes and Standards. Train Control must then: • Endorse this correct repeat time on the Train Control copy of the track warrant. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 419 - 409 Warrant In Effect Once Issued (a) A track warrant, once issued, is in effect until either: • the addressee has reported clear of the limits of the track warrant, or • it has been cancelled by a further track warrant. (b) A track warrant, once in effect, must not be altered in any way. (c) When it is necessary to change its limits or instructions, a new track warrant must be issued. The new track warrant must contain the words "Track Warrant No .... is cancelled", and give the number of the track warrant being invalidated. 410 Handover of Track Warrants (a) Locomotive Engineer Change Over When a Locomotive Engineer hands over a train to another Locomotive Engineer any track warrants which are still in effect must be handed over. The relieving Locomotive Engineer must obtain a new track warrant before the train departs from that station. This procedure also applies if a crew change takes place at a location on the main line between stations. After Locomotive Engineer changeover at a station, a train may complete berthing up to the trailing indicator, signal or fouling point at the station for crossing purposes when authorised on the existing track warrant. (b) Other Addressee Change Over When it is necessary for an addressee to be relieved a new track warrant which cancels the previous one must be issued. The track warrant for the new addressee must be sent to the person being relieved who must hand it to the relieving addressee and point out the particulars of the track warrant. The relieving addressee is responsible for the “read back” of the new track warrant to Train Control. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 420 - 411 Cancelling Track Warrants (a) The Addressee must: • Report to Train Control when the main line has been cleared within the limits of the track warrant. (b) Train Control must: • Acknowledge the track warrant being cancelled with the Addressee followed by the time. (c) The Addressee will confirm by the words “that is correct” and the time given by Train Control endorsed in the space provided. Note: After reporting clear of the limits the Addressee must not again act on the authority of that track warrant. (d) Cancellation Endorsement The word "Cancelled" must be written across the face of the track warrant when either: • the addressee has reported clear of the limits, or • the track warrant has been cancelled by a further track warrant. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 421 - 412 Calling Train Control Enroute When Clause 10 of a track warrant specifies that a call is to be made at a location, then that call must be made but the train need not stop for an acknowledgement from Train Control. When Train Control acknowledges, the addressee must advise their location and the terminating limit of the warrant held. 413 Mandatory Calling of Limits As a train approaches a station warning board, distant signal, intermediate signal, or the beginning of TWC when a track warrant is held, the Addressee must call on radio channel 1 advising: • the train number; • location being approached • the terminating limit of the warrant held. This procedure also applies when approaching a station at the end of TWC. Hi-Rail vehicles and MTMV’s operating with a track warrant must also comply with this procedure, advising the vehicle identification number if not operating with a train number. When MTMV’s are travelling as a train, the train number must be used. When calling on the radio make sure there are no other transmissions on channel 1 otherwise your transmission will not be heard correctly. 414 Train Handling - Approach to a Warrant Station (a) Station Warning Board Locomotive Engineers must have their train under sufficient control after passing a Station Warning Board to enable the train to stop before the Arrival Signal or Facing Points Indicator. (b) Marker Posts The train must be sufficiently under control before reaching the Marker Post to enable it to stop before the Arrival Signal or Points Indicators. (c) Starting Signals or Trailing Points Indicators • Locomotive Engineers must have their train under sufficient control to enable the train to stop before the Starting Signal or Trailing Points Indicator. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 422 - 415 Warrant Station – Crossing of Trains (a) When crossings are required the Addressees must, before entering the station: • Establish the whereabouts of each other by calling on radio channel 1 If radio contact cannot be established: • except as prohibited in Rule 415 (c), entry into the station may occur after visual observation indicates it is safe to do so, or • request Train Control to establish and advise the whereabouts of the opposing train. In all situations a clear understanding must be achieved as to the berthing arrangements to prevent both movements entering the station at the same time. (b) If the first train to arrive berths on the main line the Locomotive Engineer must set the route for the opposing train to enter the loop and, where arrival signals/points indicators are not provided, hand signal the train into the loop. (c) If the first train to arrive is required to stop significantly short of the trailing points when berthing on the main line: The train must not enter station limits until: • the Locomotive Engineer of the opposing train has been contacted, and, • acknowledge that the first train is stopping short on the main line, and, • acknowledge that the main line points will not be set for the diverging route. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 423 - 416 Warrant Station – Arrival Signals, Points Indicators and Hand Points (a) Arrival Signals and Points Indicators Where provided Arrival Signals and Points Indicators are controlled by track circuiting and operate automatically for most movements. They may also be controlled manually by operation of pushbutton controls. (b) Hand Points Where the main line points are equipped with a hand lever they will be secured with a TW lever lock and an AS padlock unless otherwise specified in the Rail Operating Procedures. When a TW lever lock is provided the key will be impounded when the lever is unlocked and cannot be removed until the lever is secured in the normal position. The Addressee must ensure hand points are restored to normal after use and locked. Exception: Where authorised by Rail Operating Procedures, High Column Switch Stand points may be left locked in the reverse position. (c) Arrival Signals • The Arrival signals are equipped with an "L" light and an "A" light. At a Junction the “L” light is omitted from the Arrival signal that does not have a route to the branch line. • The "L" light illuminated indicates that the points are set for the crossing loop or between the branch and main line but not necessarily that the route is unobstructed. • The "A" light illuminated indicates that the motor points are correctly set and secured for either the mainline, loop or branch line but not necessarily that the route is unobstructed. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 424 - 417 Operation of Warrant Stations equipped with Arrival Signals and/or Points Indicators • Push button controls for Arrival signals and Points Indicators operate in an identical manner at the new type loops. At other loops full control is only available at the Arrival signal/Facing Points Indicator. • When trains are to cross at a station or junction, pushbuttons will normally need to be operated for one train only. Remaining movements will be signalled automatically. • The pushbutton controls must be operated in the following circumstances: Situation Action Required The first train to arrive for a crossing has berthed on the main line. • Operate the “Stop” button at the Trailing Points Indicator. • Where a time delay light is fitted wait for this to extinguish then operate the loop button. • Close the control box door. The first train to arrive is required to berth on the loop. • The “Stop” button at the Arrival signal/Facing Points Indicator must be operated. • Wait for the time delay light to extinguish. • Operate the loop pushbutton. • Close the control box door. A train (or shunt) is depart from the loop when no crossing has taken place. • Operate the “Loop” button at the Trailing Points Indicator. To move the points for shunting. • Operate the controls from a control box (new station type) • Operate the controls from the Arrival signal/Facing Points Indicator control box (old type) Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 425 - Situation Action Required A train has arrived at a junction and the required route indication is not displayed. • Operate the “Stop” button at the Arrival Signal/Points Indicator. • The Signals/Points Indicators will revert to stop. • Where a time delay light is fitted wait for this to extinguish then operate the main/branch button. • Close the control box door. To hold a signal or indicator at stop. • Operate the “Stop” button. • Leave the control box door open. To obtain a proceed indication after a “Stop” button has been operated • Operate the “main” or “loop/branch” button. • Close the control box door. A movement is to enter or leave the backshunt at the end of the loop. • Operate the key switch alongside the control buttons for the Trailing Points Indicator. • Leave in the “GO” position until the movement is clear of the points. When delayed at a warrant station and a level crossing is located within 600 metres of the Signal/Points Indicator at which the train is stopped. The Locomotive Engineer must ensure the alarms do not operate continuously and delay road traffic. • Operate the Arrival signal/Points Indicator control stop button. • The Signal/Points Indicator will revert to stop. • The alarms will stop operating after the time delay has run. • Once the train is ready to proceed: • Operate the Main or Loop/Branch button. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 426 - Situation Action Required A vehicle or vehicles which cannot be relied upon to operate track circuits requires to berth on or depart from the main line. (Old type) • Operate the Ganger’s Control Switch at that end of the station. • Leave in the “ON” position (New station type) • Operate the Ganger’s Control Switch at that end of the station. • Ensure that the points locked indication or “A” light is illuminated. • Leave in the “Main” position • With both types the switch must be left in this position until the movement has passed completely over the points • Further details concerning the operation of Arrival signals and Points Indicators are included in the appendices at the completion of the Track Warrant Rules. 418 Sidetracked Trains to be drawn in Clear Sidetracked trains must be drawn in clear of Signals, Points Indicators or the fouling point before advising Train Control that the train has arrived. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 427 - 419 Working of Sidings off the Main Line (a) Procedure The Addressee must: • obtain an appropriate track warrant,’ • operate the main line points. • restore the main line points, ensuring they are locked in the normal position and all is safe for the passage of trains through on the main line. (b) To completely enter a siding and allow other trains to pass on the main line. • certify to Train Control that, - the main line points are secured in the normal position, and - the main line will not again be fouled, or - the main line points will not be operated, until authorised to do so by subsequent track warrant. • clear limits of the track warrant. This process should be carried out once the items in the first bullet point have been completed Upon receipt Train Control may authorise other movements on the main line. (c) Track warrants issued to trains running through on the main line while the train is locked in a siding must contain advice of the train in the siding. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 428 - 420 Train Disabled When a train becomes disabled: • The Locomotive Engineer must advise Train Control of the failure. • Train Control will arrange for a relief train and advise the Locomotive Engineer of the direction relief will arrive from. • The Locomotive Engineer will then proceed on foot in the direction from which the relief train will arrive from and will locate and identify the first full or half km peg, tunnel portal, signal, points indicator, intermediate board or main line hand points beyond the train. • The Locomotive Engineer will then proceed a further 200 metres and must place three detonators 10 metres apart on each rail at this point. • The Locomotive Engineer will then proceed back to the metrage peg, tunnel portal, signal, points indicator, intermediate board or main line hand points and advise Train Control of this place and that detonator protection has been established. • Train Control will then issue a Track Warrant to the Locomotive Engineer of the disabled train instructing that the train not be moved, and confirming the location that the relief train will arrive from. • Train Control will then issue a Track Warrant to the relief train advising the location of the disabled train and the method for its removal. • The relief train will be piloted to the disabled train from the detonator protection. • The person piloting the relief train must remain at a safe distance from the detonators. (recommended distance 50 metres) • If the distance that the Locomotive Engineer is required to walk will exceed 1km or should a tunnel or deep cutting intervene, then the Locomotive Engineer and Train Control must come to an agreement on the time of the next radio call. Note: If the detonator protection cannot be provided due to a bridge without walkways or a constrictive tunnel or other physical obstruction making it unsafe to do so. ? The Locomotive Engineer must advise Train Control. ? Train Control must advise the relief train of the situation and direct that, while in the obstructed section, the speed must be reduced to enable the relief train to stop in half the clear distance that can be seen ahead. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 429 - Example of detonator protection Figure 408 421 Train Divided or Stalled (a) When a train is divided or stalled owing to an accident or the inability of the locomotive to take the whole of the train forward, and the locomotive has to take forward a portion of the train and return for the remaining part of the train: The Locomotive Engineer must: • Arrange for the rear portion of the train to be secured. Train crew or staff asked to assist must: • Uncouple the portion that is to be taken forward. • Hand signal the Locomotive Engineer to move this portion forward approximately 200 metres. • Three detonators are to be placed 10 metres apart on each rail at a distance of 200 metres from the front vehicle of the rear portion to warn the Locomotive Engineer, when returning, of the position of the remainder of the train. • Advise the class and number of the rear vehicle on the front portion to the Locomotive Engineer. Establishing Protection Station A Disabled train Station B 1/2 or full k m peg or other authorised permanent fixture 10m apart 200m Detonator Protection Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 430 - The detonators provide an audible warning to the Locomotive Engineer when returning for the remainder of the train. Train Divided • Accidental When a train has become accidentally divided and both portions have come to a stop within sight of each other and a controlled signal does not intervene the front portion may be signalled back to the rear portion provided the two portions can be effectively coupled. If there is a locomotive assisting in the rear of the train the permission of the Locomotive Engineer of the locomotive must be obtained. Should the rear portion not be in sight the Locomotive Engineer or the person asked to assist must proceed back and once the whereabouts of the rear portion has been established the front of the train can then be moved back provided the two portions can be effectively coupled. If the train cannot be coupled and it is necessary for the train to be removed from the section in more than one portion then the procedures set out for train stalling must be observed. • Planned When a train is carrying out maintenance work and it is necessary because of the nature of the work to divide the train then after the rear portion has been adequately secured the front portion of the train can be moved forward to carry out the required work. Once this has been completed the front portion must return to the remainder of the train and be coupled. (b) Precautions when Double Banking The Locomotive Engineer, on arrival at the station, must check that the front portion has arrived complete, advising Train Control and the Officer in Charge if the station is attended. Train Control after ensuring that: • A current Track Warrant held to permit the locomotive to recover the remaining portion of the train. • No subsequent authority has been granted for Track Occupancy, i.e. stock crossing/foul time. • At an interlocked station • Points are correctly set and • Proceed indication on the Starting Signal. The Locomotive Engineer may then return and remove the remainder of the train out of the section. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 431 - (c) Display of End of Train Marker An End of Train Marker must not be carried on the locomotive or last vehicle of the front portion of the train while in a Track Warrant Control area. If the locomotive or front portion of the train has to pass out of a Track Warrant Control area an End of Train Marker must then be placed on the rear.

Check Track Warrant limits before proceeding.. # At Kai Iwi and Ruatangata the “L“ light illuminated also indicates that the loop to sidings points are set for the loop. Note: • If two opposing trains are closely approaching the station at the same time, both main line arrival signals will display red over red with the “A” light illuminated. At a Junction this includes a branch/main line situation. • A main line Arrival signal will revert from “Caution Normal Speed” to Stop if a second train occupies the track circuit approaching the other end of the station. @ If an “A” light is extinguished when either a Caution Normal Speed or “L” light indication is displayed the points are still correctly locked and set for the intended route. The defective A light must be reported to Train Control for repair Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 434 - Trailing Points Indicator Meaning Trailing Points Indicator Aspect Red • Stop. • The motor points may be incorrectly set, or • A “stop” pushbutton may have been operated, • Operate the push button in accordance with TWC Rule 417 If the required aspect fails to display: • Advise Train Control of fault. • Secure the Motor points, for the intended movement, before passing over them. • Check Track Warrant limits before proceeding. (b)Signals Controlled by Signaller Any signal may be passed at “Stop” on the receipt of verbal or written instructions from, or the exhibition of proper hand signals by, the Signaller who controls that signal. The Signaller must not give such verbal or written instructions or hand signals when a fixed signal can be properly used for the movement. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 435 - (c) Train Stopped at Intermediate Stop and Proceed Signal. (i) When a Locomotive Engineer observes a Stop and Proceed signal at Stop the train must be stopped before the signal, if at the expiration of 10 seconds the signal is still at stop the train may proceed cautiously in accordance with the conditions of the Track Warrant. The Locomotive Engineer being prepared to find the line ahead to the next fixed signal may either be; occupied, obstructed or have displaced rail. (ii) Where there are mainline points on the line ahead of a Stop and Proceed signal which has been passed at Stop the Locomotive Engineer must examine the points to see they are correctly set and secured so that the train may pass safely over them. (iii) After passing a Stop and Proceed signal at Stop the Locomotive Engineer must regulate the speed of the train being able to stop short of an obstruction within half the distance of clear line that is visible ahead. (iv) Level crossings on the line ahead equipped with automatic alarms must also be approached with caution as they may not operate correctly. (v) If the signal next in advance is observed to be at “Caution” or “Clear” the Locomotive Engineer must not relax vigilance but must, until they reach the signal, be prepared to stop the train clear of any obstructions. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 436 - KiwiRail Rail Operating Rules Section 4 Appendix to Track Warrant Control Rules Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 437 - Appendix to the Track Warrant Rules - Rule 417 Operation of Arrival signals and Points indicators in Track Warrant Control territory. The information in the appendices is in addition to that detailed in Track Warrant Rule 417. Automatic Operation • The automatic operation of the system is controlled by track circuiting which can identify the direction in which a movement is being made, but cannot tell the difference between vehicles which operate track circuits, trains or track circuiting faults. • The system works automatically for through movements on the main line while the loop is not occupied. Facing Points Indicator type • When a train approaches, the indicator will clear to purple to show the motor points are locked and set for the main line. As the train passes the indicator will turn red. Arrival Signal new station and old type • When a train approaches, the Arrival signal will clear to a yellow aspect to show the track circuited section is clear and the motor points are locked and set for the main line. As the train passes the signal will turn red. Note: If the loop is occupied the system may operate as though a crossing is taking place (see below). • For a crossing of opposing trains which takes place in the normal sequence (one train berths, second train passes through and first train departs) the system will work automatically when the controls are operated as described in the first or second situation in this rule. • Most other movements need to be wholly or partly controlled manually by the pushbutton controls. For example, if the crossing is an overtaking movement the train to use the loop will need the pushbuttons operated to enable it to enter the loop and the train being overtaken will need the pushbutton operated to depart, whether it is on the loop or the main. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 438 - • The system will restore all motor points to the normal position when all control boxes on the main are closed and all of the track circuited area is unoccupied. (The position of the loop control box doors will not affect this operation). • The system may assume that any train, vehicle or track circuit fault in a track circuited area is a train to which it should react. The system may operate as though that vehicle etc. is part of the normal crossing sequence. Example 1 A train passes through the station on the main while a wagon is standing on the loop. The system may treat that wagon as a train and set the road for the wagon to depart from the loop when the train has cleared the points at the entrance to the station. The points will remain reversed until reset manually by operation of the pushbuttons. Example 2 A train which is to pass through a station without crossing another train, stops at the station to shunt off the main line. The system may treat the movement from the main, across the loop to the siding, as a train entering the loop for a crossing. If this happens the main line points at the other end of the loop will reverse behind the train on the main. These points will remain reversed until either they are returned to the normal position by the push-button controls, or they operate automatically as detailed in the seventh paragraph on the previous page. At a junction the system operates in a similar manner to the end of a crossing station. A movement on the "normal" route (usually the main line) will be like a movement on the main at a crossing station. A movement on the other route (usually between branch and main line) will be like a movement on the loop, with the following exception; the system will automatically set the route to the main for a movement which approaches either Trailing Arrival Signal if no other track circuit is occupied. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 439 - Manual Operation Control Boxes - Location and Function • A control box (secured with an AS padlock) is at each Arrival Signal/Facing Points Indicator and a gangers control box (secured with a 100 padlock) is at each end of the crossing loop. • The control box at the Arrival Signal/Facing Points Indicator has three pushbuttons and a "time delay operating" indication lamp. The "Stop" button cancels the route indicated. The "Main" and "Loop" buttons select the relative route. New station type • A control box (secured with an AS padlock) is at each Trailing Points Indicator on the main. The control box is the same as the control box at the Arrival signal and operates in an identical manner. There is no control box at the Trailing Points Indicator on the loop. Old type/Facing Points Indicator type • A control box (secured with an AS padlock) is at each Trailing Points Indicator on the main. The control box has two pushbuttons. The “Stop” button cancels a route which is indicated as being set for the main. The “Main” button reselects a route for the main after it has been cancelled either by the “Stop” button or by the train passing the indicators. Example 1 - All locations A train enters a station on the main for a crossing. The "Stop" button in this control box must be operated. If after the points indicator has been cancelled it is found that the crossing will not take place, the "Main" button must be operated to get an indication for the train to proceed. Example 2 After a train enters the main at a station it is found necessary to set back past the Indicator behind the train. (Old type/Facing Points Indicator type) The “Main” button in the control box behind the train must be operated to obtain the indication that the route is correctly set. (New station type) The “Stop” button in the control box behind the train must first be operated followed by the “Main” to obtain the indication that the route is correctly set. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 440 - Movements on the loop (Old type/Facing Points Indicator type) • The control box at the Trailing Points Indicator on the loop also has two pushbuttons. The "Stop" button cancels a route which is indicated as being set for the loop. The "Loop" button selects a route from the loop when a crossing has not taken place, or reselects after it has been cancelled by either the "Stop" button or by the train passing the indicators. Where there is a purple arrow for movements into a backshunt in the Indicator there will also be a key switch in the control box. If the key switch is turned "on" when the points are in the normal position the purple arrow will light up. Gangers Control (Old type/Facing Points Indicator station) • The gangers control is used for movement of vehicles which do not operate track circuits over the points when set for the main line. The control box contains a switch and a "Points set for the main line" indication lamp. When the switch is turned "on" while the points are in the normal position, the points will lock normal, the Arrival signal/Facing Points Indicator and Trailing Points Indicator will both clear to a proceed aspect and the indication lamp above the switch will light up. When the switch is turned "off" the Arrival Signal/Facing Points Indicator and Trailing Points Indicator will both revert to stop and the indication lamp will go out. The points will remain locked for a further 30 seconds. The door of the control box cannot be shut unless the switch is in the "off" position. Note: The switch will not cause the points to move to the normal position if the points are either in the reverse position or not properly normal when it is operated. Gangers Control (New station type) • The gangers control is used for the movement of vehicles which do not operate track circuits over the points. The control box contains a switch and a "Points Locked" indication lamp. When the required movement is over the points set for the main, operate the control switch to the “Main” position. The “A” light and the “Points Locked” indication light above the switch will light up. When the movement has been completed and is clear of the points operate the switch to the “Off” position, the “A” light and indication lamp will go out. When the required movement is over the points set for the loop, operate the switch to the “Loop” position. The points will drive to the reverse position (set for the loop), the “A” light, “L” light and the “Points Locked” indication light above the switch will light up. When the movement has been completed and is clear of the points operate the switch to the “Off” position, the “A” light, “L” light and indication lamp will go out and the points drive to the normal position (set for the main). The door of the control box cannot be shut unless the switch is in the "off" position. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 441 - Note: The switch WILL cause the points to move to the position of the switch if the points are not already in that position. If the points are reverse when the switch is operated to the “Off” position the points WILL move to the normal position. Control Box at Arrival Signal (old type)/Facing Points Indicator ?? When the Door is Open • Train Movements td outside station limits When a train which has just moved out of the station is present and occupying the track circuit outside the Arrival Signal/Facing Indicator: If the movement came from the main the Trailing Indicator and Facing Indicator will re-clear for the main and the Arrival signal “A” light will light up with the top unit at red. If the movement came from the loop the Trailing Indicator and Facing Indicator will re-clear for the loop and the Arrival signal “A” and “L” lights will light up with the top unit at red The Signal/Indicators will remain set until the "Stop" button is operated. Where there are level crossing alarms between the Arrival Signal/Facing Indicator and the Trailing Indicator the Signals/Indicators will not re-clear if the movement has cleared the crossing. • Train Approaching Facing Indicators When a train is approaching (or has approached) the Facing Indicator and the indicators have cleared automatically the indicators will, remain cleared for the route set. • Train Approaching Arrival Signals When a train is approaching (or has approached) the Arrival Signal and the indicators have cleared automatically for the main line the Arrival Signal will revert to Red over Red with the “A” light lit, the Trailing Indicator will, remain cleared for the route set. When the Arrival signal has cleared automatically for the loop, Red over Red with “A” and “L” lights lit, the trailing indicator and Arrival Signal “A” and “L” lights will remain cleared for the route set. The indicators at that end of the station will not operate automatically. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 442 - ?? How to Take Control Operate the "Stop" button. After the time delay light has extinguished (30 to 110 seconds), operate the button for the required route. Where there are level crossing alarms between the Trailing Indicator and Arrival Signal /Facing Indicator it will be necessary to re-clear the Signal/Indicators with the relative “Main” or “Loop” button for each movement past either a Signal or Indicator. This may be done from the controls at the Signal or Indicator. Control Box at a Trailing Points Indicator on the Main (old type) • An indication that the points are set for the main can be cancelled from this control box after it has been lit up for 60 seconds and the train has occupied the main line between the Trailing Points Indicators for 60 seconds. • 30 seconds after the indication has been cancelled the points will drive over to the loop route. • An indication that the points are set for the loop cannot be cancelled from this control box. • If the door of the control box is left open it will prevent the points at that end of the station from moving to the normal position. It will not prevent the points moving from normal to reverse when the Indicator is showing "Stop". Control Box at a Trailing Points Indicator on the Loop (old type) • An indication that the points are set for the loop can be cancelled by operating the "Stop" button in this control box. • 30 seconds after the indication has been cancelled the points will drive over to the main line route. At locations where a purple arrow is provided the purple arrow must also have been extinguished for 30 seconds. • An indication that the points are set for the main cannot be cancelled from this control box. • If the door of the control box is left open it will prevent the points at that end of the station from moving to the reverse position. It will not prevent the points moving from reverse to normal when the Indicator is showing "Stop". Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 443 - Control Box at Arrival Signal and Main Trailing Indicator (new station type) The control boxes at the Arrival signal and at the main line Trailing indicator are identical. If it is necessary to change the route set for a movement to the main or loop, manual control of the points can be taken from either control box at that end of the station. Opening of the control box door has no effect on the operation of the signalling system. ?? How to Take Control Operate the "Stop" button. After the time delay light has extinguished (30 to 110 seconds), operate the button for the required route. It will be necessary to re-clear the Signal/Indicators with the relative “Main” or “Loop” button for each movement past either a Signal or Indicator. Control Boxes at Junctions The control box at the facing and trailing Arrival signals at a junction operates in a similar manner to that on a main line at the end of a crossing station (old type). Sequence of Normal Crossings Example 1 The first train to arrive for a crossing is to berth on the main. Facing Points Indicator Type • When the front of the train entering the main passes the Facing Points Indicator the adjacent Trailing Indicator will turn red. When the front of the train passes this Trailing Indicator the indicators at the other end of the station will light up to show those points set for the main. The Facing Points Indicator will turn red when the rear of the train passes it. Arrival Signal Station (both types) • When the front of the train entering the main passes the Arrival Signal, the signal will turn red, the “A” light will remain lit; at an original type stations the adjacent Trailing Indicator will turn red (at the new station type the Trailing indicator is already at red). When the front of the train passes this Trailing Indicator, the Trailing Indicator at the other end of the station will light up to a purple aspect to show those points set for the main. The “A” light on the Arrival Signal will go out when the rear of the train passes the signal. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 444 - After the train has berthed on the main Arrival Signal (old type) and Facing Points Indicator Type • After the train has berthed, the "Stop" button in the main line control box at the Trailing Points Indicator must be operated and the door closed, (first situation in this rule). The points at the end of the station will automatically set for the opposing train to enter the loop. When the train to berth on the loop reaches the track circuited area the Arrival signal “A” light and “L” light will light up, the Facing Points Indicator (where installed) and Trailing Points Loop Indicator will clear to a purple aspect. Arrival Signal (new location type) • After the train has berthed, the "Stop" button in the main line control box at the Trailing Points Indicator must be operated, wait for the time delay to extinguish (110 seconds), then operate the loop button and close the door. The points at the end of the station will set for the opposing train to enter the loop. When the train to berth on the loop reaches the track circuited area the Arrival signal “A” light and “L” light will light up. After train has berthed on the loop Arrival Signal (old type) and Facing Points Indicator Type • When the front of the train entering the loop passes the Arrival Signal/Facing Points Indicator, the loop Trailing Indicator will turn red. All types • When the rear of the train berthing on the loop passes this Arrival Signal/Facing Indicator, + the “A” and “L” lights will go out/Indicator will go red. • When the train enters the loop the route will (if the train on the main is in clear of this Trailing Indicator) set for the train to depart from the loop (the exact point at which this happens may vary from loop to loop). If the train on the main is not in clear the route will set when that train pulls in clear of the Trailing Indicator. • When the rear of the train entering the loop clears the Trailing Indicator the route at that end will set for the train on the main to depart. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 445 - When both trains have departed • When both trains have departed and cleared the track circuited area the main line points will restore to "Normal" Arrival Signal (old type) and Facing Points Indicator Stations • If one of the trains is required to wait for more than one train, after operating the "Stop" button at the Trailing Indicator the door of the control box may be left open. The system will work automatically if the door is closed when only one train has still to arrive. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 446 - Example 2 The first train to arrive for a crossing is to berth on the loop before the opposing train arrives. • The "Stop" button in the control box at the Arrival Signal/Facing Points Indicator must be operated. After the "time delay light" has extinguished the "loop" button must be operated and the door of the control box closed (second situation in this rule). Facing Points Indicator Type • When the front of the train entering the loop passes the Facing Points Indicator the adjacent Trailing Indicator will turn red. If not already lit, when the front of the train passes the Trailing Indicator the indicators at the other end of the station will light up all red but will not indicate the points set for the main until the opposing train is in the track circuited area. The Facing Points Indicator will turn red when the rear of the train passes it. Arrival Signal (both types) • When the front of the train entering the loop passes the Arrival Signal the signal will turn red, the “A” and “L” lights will remain lit and at the old type stations Trailing Indicator will turn red (at new type stations the Trailing indicator is already at red). If not already lit, when the front of the train passes the Trailing Indicator the loop indicator at the other end of the station will light up all red but the Trailing Indicator and adjacent Arrival signal will not indicate that the points set for the main until the opposing train is in the track circuited area. The “A” and “L” lights on the Arrival Signal will go out when the rear of the train passes the signal. All types • When the rear of the train entering the loop clears the Trailing Indicator and points at that end, the points will restore to normal. When opposing train enters the main Facing Points Indicator Type • When the opposing train entering the main line arrives and the front passes the Facing Points Indicator, the adjacent Trailing Indicator will turn red. The Facing Points Indicator will turn red when the rear of the train passes it. Arrival Signal (both types) • When the opposing train entering the main line arrives and the front passes the Arrival Signal the signal will turn red, the “A” light will remain lit and at old type stations the adjacent Trailing Indicator will turn red (at new type stations the Trailing indicator is already at red). The “A” light on the Arrival Signal will go out when the rear of the train passes the signal. Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 447 - All types • When the rear of the train clears the adjacent Trailing Indicator the route at that end will set for the train on the loop to depart. • When both trains have departed and cleared the track circuited area the main line points will restore to "Normal. Train required to wait for more than one train All types • If one of the trains is required to wait for more than one train, after operating the "Stop" button at the Trailing Indicator the door of the control box may be left open. The system will work automatically if the door is closed when only one train has still to arrive except that at the new type stations the “Stop” button is to be operated after each through movement. Example 3 Train arriving at the Junction from the Branch The first train to arrive at a junction is the train from the Branch. That train is to wait for another train to pass through on the main line before it passes through the junction onto the main line. • As the branch train approaches the junction the route will set for the train to proceed through the junction on to the main line. • The train must be stopped short of the Trailing Arrival Signal. The signal should be cancelled from the control box at the Arrival Signal on the branch and the door closed. • If the main line train is travelling in the opposite direction to the branch train, the route will again set for the branch train to proceed through the junction after the main line train has gone past. • If the main line train is travelling in the same direction as the branch train, the route will not automatically set for the branch train to follows the main line train. The "Branch" pushbutton at the Branch Arrival Signal must be operated after the train has passed to set the route for the branch train to follow. • When both trains have departed and cleared the track circuited area, the main line points will restore to "Normal". Uncontrolled Copy KiwiRail Rail Operating Rules Section 4: Track Warrant Control Rules - 448 - Example 4 Train arriving at a Junction on the Main Line The first train to arrive at a junction is approaching from the direction of the trailing Arrival Signal on the main line. The train is to wait for a branch train to pass through the junction onto the branch or from the branch onto the main line ahead of the first train. • As the first train approaches the junction the route will set for it to proceed through the junction on the main line. • The train must be stopped short of the trailing Arrival Signal. The signal must be cancelled from the control box at the trailing Arrival Signal on the main and the door closed. • If the branch train is travelling in the opposite direction to the first train, the route will again set for the main line to proceed through the junction after the branch train has gone past. • If the branch train is travelling in the same direction as the first train, the route will not automatically set for the main line train to follow the branch train. The "Main" pushbutton at the trailing Arrival Signal must be operated after the train has passed to set the route for the main line train to follow. Uncontrolled Copy
