1 Introduction 1.1 Purpose 1.1.1 Capacity Assessments Capacity Assessments (CA) of the CQCN are undertaken to determine if there is sufficient Capacity to meet the Committed (or contracted) Capacity and any changed or additional capacity requested by an Access Seeker in an Access Application.

Further to these Capacity Assessments undertaken for new or modified access Aurizon Network performs • Capacity Assessments on an annual basis for publication in the Capacity Assessment Report. • Capacity Assessments to assess changes to infrastructure or operations to support expansions in the CQCN.

1.1.2 System Operating Parameters When a Capacity Assessment is undertaken, it is based on a definition of Capacity and the application of a defined methodology and input parameters. This document is the System Operating Parameters (SOP) and describes • the definition of Capacity applied, • the methodology, • the input parameters used and • an explanation of why these inputs have been used when undertaking the Capacity Assessment.

1.1.3 System Capacity Assessment System Capacity Assessments are broader assessments of the capacity of the Supply Chain and include broader supply chain constraints outside of Aurizon Networks control. These may impact how Access Holders (and Seekers) utilise Capacity.

Following the completion of the Capacity Assessment Aurizon Network will undertake a System Capacity Assessment.

System Operating Parameters / 2019 PCAR 4 Aurizon Network 2019

2 Capacity

The purpose of this section is to

• Provide Aurizon Networks definition of Capacity

• Describe how the definition of Capacity is used within our simulation tools

• Describe the pass and fail criteria of Capacity Assessments

• Explain the exclusions outside of the capacity definition and how the System Capacity Assessment will incorporate those factors

2.1 Capacity Definition The definition of the capacity of the network that Aurizon Network applies is

The number of trains that can be operated in the CQCN taking into account the processes by which trains are scheduled and the impact that Aurizon Network has on

(a) when those trains can be scheduled (availability)

(b) how they operate (cycle time and Network caused losses)”

This excludes external factors1 which Network does not control and there are no contracted understandings between parties including

• Reliability and availability of rolling stock • Reliability and availability of mine loadout (and recharge time) • Reliability, availability and mode of operation of port

2.1.1 Relationship to UT5 Under UT5, Aurizon Network is obliged to complete an annual capacity analysis to determine the Capacity of the Rail Infrastructure, comprised in each of the Coal Systems it manages. As a result, it is the capacity of the Rail Infrastructure, not the supply chain as a whole, which is the focus of Aurizon Network’s Capacity Assessments.

Aurizon Network has developed its System Operating Parameters to align with its contractual commitments to its access holders. This is important as each of Aurizon Network and its access holders are bound by those commitments, and they represent an objective baseline from which to measure Rail Infrastructure capacity. This approach also recognises that Aurizon Network only controls and operates the Rail Infrastructure and cannot dictate how other supply chain participants approach key considerations which impact on overall supply chain capability. These considerations include matters

1 These factors are considered part of the System Capacity Assessment

System Operating Parameters / 2019 PCAR 5 Aurizon Network 2019

such port operating methodology, mine and port inventory levels, volume and availability of rollingstock and appetite to invest in infrastructure and systems.

This approach is consistent with UT5, which requires that in conducting its capacity analysis Aurizon Network must include “consideration of the following factors

(A) The terms of Access Agreements relating to Train Services operating in each Coal System; and (B) The interfaces between the Rail Infrastructure and other facilities forming part of, or affecting, the relevant Supply Chain” (clause 7A.4.2(b)(iv))

Access Agreements include the following factors (including factors relating to supply chain interfaces) that are used in the generation of the System Operating Parameters. These include:

• Number of Train Service Entitlements (TSEs) required • Mode of operation (even railings) • The time taken for trains to traverse sections of the network (Section Run Times or “SRTs”) • The time at interface locations (load and unload times) • How operators will operate on the network – described in Operating Plans

These parameters are a joint agreement between Aurizon Network and Access Holders on how the Access Holder will operate on the Rail Infrastructure.

Aurizon Network note that Access Agreements do not always reflect the current scheduling and operating parameters. Therefore, the parameters relating to loading, unloading and SRTs have been updated to reflect the scheduled parameters in the 2019 SOP and Capacity Assessment. 2.2 Application within simulation suite 2.2.1 Planning, Scheduling and Operating processes The process by which trains are planned, scheduled and operated is summarised below, this forms the basis of the simulation approach and structure of the SOP.

2.3 Exclusions and incorporation in System Capacity Assessments There are a range of parameters that there are no contracted understandings between Aurizon Network and other parties including:

From feedback received during on SOP and BCA, Aurizon Network have identified that there is a desire from stakeholders to understand the Supply Chain Capability. These items are activities or actions that affect the Supply Chain Capability and are outside of the control (or agreed interface parameters) of Network. These include:

• Mine, Port or Train availability: Losses associated with the (planned) time that mines / ports or rolling stock are not available for the movement of coal through the supply chain.

• Mine, Port, Train or external DOO loss: Losses associated with failures and other events outside of the control of Network. This may include items such as load and unload time variation through to rolling stock failures and coal availability.

• Supply Chain Operation: The mode of operation and how trains are ordered differ from the even railings basis by which Network capacity is derived and can lead to losses.

• Payload variation: Network provides capacity in the form of Train Service Entitlements (TSEs) which are derived using a payload as part of the Access Request process. Actual payload can vary.

• Force Majeure: Losses associated with significant events that trigger force majeure events.

• Demand: The changes in demand above and below the contracted demand

These factors (and other relevant parameters) will be considered in the System Capacity Assessment

System Operating Parameters / 2019 PCAR 8 Aurizon Network 2019

3 Network Configuration

This section of the SOP describes the infrastructure used in Capacity Assessments. It contains information regarding the network: • Configuration • Speeds • Signalling • Interfaces, including: o Yards o Ports o Mines • Operational Constraints 3.1 Infrastructure configuration

The infrastructure configuration used in the model reflects the committed infrastructure, which is the existing infrastructure and modifications already committed to over the life of the capacity analysis.

3.1.1 Planned changes Capacity Assessments are based on the existing infrastructure with the following changes

• RCS implemented in the Newlands system between Collinsville and Newlands Jn (see section 3.3.1) • Drake connection in the Newlands system • Washpool connection in the Blackwater system • Olive Downs connection in the Goonyella system • Meteor Downs South connection in the Blackwater system • Starlee passing loop in the Blackwater system

A summary of the CQCN is provided in Figure 2. A more detailed representation of the network through line diagrams is provided in the Review of Rail Infrastructure and Line Diagrams for the Central Coal Region1 published on the Aurizon website.

Figure 2: CQCN summary overview

System Operating Parameters / 2019 PCAR 10 Aurizon Network 2019 3.2 Sectional Running Times (SRTs) SRTs can be sourced from

• Access Agreements

• System Operating Parameters

• Scheduled

• Actual

Historically the SOP has been based on the parameters contracted in Access Agreements. Feedback on previous SOPs has indicated that this is not preferred, and Aurizon Network notes that Access Agreements do not always reflect the current scheduling and operating parameters. Therefore, the parameters relating to loading, unloading and SRTs have been updated to reflect the scheduled parameters in the 2019 SOP and Capacity Assessment

3.2.1 Start / Stop allowances SRTs are produced for continuous green light running (with the exception of arriving and departing mines, ports and yards). When scheduling services an increase in time is applied to reflect the additional time to traverse the section whenever a train needs to start or stop. This additional time is used in the CA whenever a train needs to start or stop.

System Operating Parameters / 2019 PCAR 11 Aurizon Network 2019 3.3 Signalling Description Aurizon Network has three signalling systems in place across the CQCN • Remote Control Signalling (RCS) • Direct Train Control (DTC) • DTC with Main Line Point Indicators (DTC-MLPI)

This section of the SOP describes where each signalling system is and how it is implemented in the Capacity Assessment. The specific application of the signalling is sourced from the relevant AS plan.

3.3.1 Newlands System

The Newlands system currently operates with a mix of RCS and DTC-MLPI signalling. Full RCS installation has been deferred while system demand is lower than contract. As this infrastructure will be in place prior to full contracted capacity being reached, the assessment assumes RCS to be installed across the entire Newlands System. This provides a better measure of whether full contract can be delivered.

Figure 3: Newlands system and NML train control map

System Operating Parameters / 2019 PCAR 12 Aurizon Network 2019

3.3.2 Goonyella system The Goonyella system has RCS throughout.

Figure 4: Goonyella system train control map.

System Operating Parameters / 2019 PCAR 13 Aurizon Network 2019

3.3.3 Blackwater system The Blackwater system has RCS throughout with the exception of the Rolleston and Minerva branches which have DTC installed. Memooloo (on the Rolleston branch) has DTC-MLPI installed.

Figure 5: Blackwater system train control map

System Operating Parameters / 2019 PCAR 14 Aurizon Network 2019

3.3.4 Moura system The Moura system is largely RCS with the exception of DTC on the Dakenba branch (to Callide) and DTC-MLPI west of Moura mine junction to Baralaba.

Figure 6: Moura system train control map

System Operating Parameters / 2019 PCAR 15 Aurizon Network 2019

3.3.5 Remote Control Signalling (RCS) RCS is a system of safe working where rail traffic movements are regulated by signals usually controlled from a remote location and/or automatically by the passage of rail traffic. The RCS system operates on the principle of only one rail traffic movement being on a signal section at one time. Key characteristics are as follows: • Normal authority for rail traffic movements is by o two, three or four colour light signals for running movements o position light signals for non-running movements • A signal at PROCEED is the authority to go forward • The position of rail traffic on the track is detected by o track circuits, or o axle counters • Points are generally controlled by points machines The application of RCS in the CA is described below.

Table 2: RCS application in CA

Activity Description Time impact (mins) Provision of authority Network controller issues authority on UTC screen which is displayed on Nominal (0) RCS to train crew Movement of trains Following the provision of an authority the time taken for a train to Nominal (0) commence moving Movement of points Route set in UTC requires points to move from Normal to Reverse (or Nominal (0) vice versa) Release of section Train exits a train detection section which is released for the provision of Nominal (0) authority of other trains

Explanatory notes Application of RCS in the CA incurs a total time impact of 0 minutes. The following points explain this in more detail:

• Provision of authority and movement of points occur in advance of train movements and are not required to occur in sequence of train movements

• Movement of trains do not incur additional time. These are captured in the start/stop times added to section run times

• Release of section automatically occurs and is detected via track circuits or axle counters

System Operating Parameters / 2019 PCAR 16 Aurizon Network 2019

3.3.6 Direct Traffic Control (DTC)

The movement of rail traffic is governed by instructions contained in DTC Authorities issued by the Network Control Officer to Rail Traffic Crew.

In Direct Traffic Control (DTC) territory the route is divided into sections known as DTC blocks, which are identified by Block Limit Boards (see Figure 7). A DTC Authority gives rail traffic possession of the block (or multiple blocks) up to a nominated Block Limit Board. Ownership of the block(s) will be passed from the Network Control Officer to the Rail Traffic Crew when the Network Control Officer issues a DTC Authority.

The actual time taken for trains to cross in DTC territory is dependent upon the interval between the first train arriving and the second train arriving. The parameters used for capacity analysis purposes represent the worst case arrival times. Waiting times between train arrivals are governed by model dynamics.

Figure 7: DTC Blocks and Position of Block Limit Boards

There are two types of passing loop configuration used in DTC territory:

1. Directional Running 2. Mainline points Indicators (MLPI)

These are described below.

System Operating Parameters / 2019 PCAR 17 Aurizon Network 2019

3.3.6.1 Directional Running In this system the passing loop turnouts are arranged with trailable facing points (TFP) such that trains can travel through the passing loop without requiring any switching of the turnouts. They are normally arranged such that loaded trains will always be routed through the mainline and empty trains through the passing loop. This system has the advantage that train crews do not need to operate the turnouts, they are very simple and inexpensive to install. The disadvantages are the TFP’s are relatively high in maintenance and require that all trains slow to 25km/h prior to entering the turnout. This is taken into account in the SRT’s.

When trains are required to cross, additional time delays are applied to the trains to replicate the processes that are carried out to cross another train. These are defined in Table 3: Crossing Time Parameters.

Table 3: Crossing Time Parameters Directional Running

Train Activity Time 1 Traverses section enters crossing loop and stops at Block Limit Board 10 mins 1 Releases Section 2 Traverses section and stops at BLB 5 mins 2 Gets authority to enter station and traverse into Section 2 Pulls forward past BLB, traverses section 5 mins 2 Releases Section once past BLB 1 Gets authority to pass BLB and traverse into Section 6 mins

1 Pulls forward past BLB and traverses Section

Explanatory notes: Train 1 is first to arrive.

Train 2 is second to arrive.

System Operating Parameters / 2019 PCAR 18 Aurizon Network 2019

3.3.6.2 Main Line Points Indicators (MLPI)

Passing loops fitted with MLPI’s have power operated turnouts and illuminated indicators to give train crews advanced indication of the direction the turnout is set. Train crews needing to enter the passing loop can set the turnout by use of a hand-held remote control.

The advantages of this type of equipment are:

• It removes the need for manual operation of turnouts by train crew. • Trains travelling through the mainline can do so at full line speed. Disadvantages include: • Higher capital cost than directional running • Crossing times are longer due to in built safety logic • Need for mains power supply

Table 4: Crossing Time Parameters -MLPI

Train Activity Time 1 Traverses Section and stops at Block Limit Board 1 Sets points for loop road 20 mins 1 Pulls forward and stops in loop 1 Sets points for mainline 1 Releases Section

2 Traverses Section and stops at BLB 10 mins 2 Gets authority to enter station and next section 2 Pulls forward past BLB and continues to next section 2 Releases previous section 1 Waits second train to clear, gains new authority 21 mins 1 Set points to enter mainline from loop road 1 Pulls forward past BLB and traverses into next section

Explanatory Notes Application of DTC-MLPI in the CA incurs a total time of 12 minutes. However, additional time is considered for the Movement of points.

System Operating Parameters / 2019 PCAR 19 Aurizon Network 2019 3.4 Electrification

Electric trains can operate throughout the CQCN with the exception of the following areas

• Newlands and GAPE systems north of North Goonyella • Blackwater system west of Burngrove • Moura system • Mt Miller branch

Figure 8: Electrification of CQCN.

System Operating Parameters / 2019 PCAR 20 Aurizon Network 2019 3.5 Yards

Yard activities that occur on Network infrastructure by Above Rail Operators are performed in accordance with their operating plans. These activities as applied to the Capacity Assessment are described in the appropriate operator appendix.

Non Network yards are included in the capacity model and assumed to provide sufficient capacity for the Above Rail operators activities and not impact Network capacity. 3.6 Interfaces 3.6.1 Load / Unload times

The primary interfaces between the CQCN and the rest of the supply chain is at mines and ports and are defined as the time taken to load and unload trains.

These interface parameters can be sourced from

• Access Agreements

• System Operating Parameters

• Scheduled

• Actual

Historically the SOP has been based on the parameters contracted in Access Agreements. Feedback on previous SOPs has indicated that this is not preferred, and Aurizon Network notes that Access Agreements do not always reflect the current scheduling and operating parameters. Therefore, the parameters relating to loading, unloading and SRTs have been updated to reflect the scheduled parameters in the 2019 SOP and Capacity Assessment.

3.6.2 Interface availability and reliability

Capacity Assessments do not take into account constraints to the operation outside of the CQCN interface point. For instance,

• constraints due to belt routes in ports are not included when assessing network capacity.

• Availability of mine or port infrastructure is assumed to align with rail network capacity

System Operating Parameters / 2019 PCAR 21 Aurizon Network 2019 4 Maintenance Scope

This section of the SOP describes how the scope for maintenance and renewal activities is generated including

• The source of historic maintenance and renewals information

• Scope of activities included

• Scaling made to possessions to reflect changes in demand between historic and contracted 4.1 Fixed activities: Maintenance, Renewals and Construction Aurizon Network’s aim is to best replicate a maintenance and renewal program that aligns accurately with current practices to provide a realistic view network availability. 4.1.1 Source In order to best align modelling with current practices Aurizon Network has used the maintenance and renewal activities detailed in each of the monthly Master Train Plan (MTP) reports for the calendar year of 2018. Aurizon’s MTP Customer Report is created monthly and contains a detailed outlook of all maintenance and renewal activities scheduled to be undertaken for the forthcoming month.

4.1.2 Scope 133 individual work types are detailed in the MTP reporting. To create greater simplicity these were allocated into the below sub groups: • BCM / Ballasting • GIJ's • Level Crossing Maintenance • OHLE Mtce • Other • Rail Repairs • Re-Railing • Re-Sleepering • Re-Stressing • Spot Resurfacing • Turnout Mtce • Undercutting

4.1.3 Scaling Work products determined by Aurizon’s Network Strategic Asset Plan (NSAP) model as tonnage dependant have been scaled up proportionally from the tonnes delivered in 2018 compared to that contracted on a system by system basis. These products are: • Ballast Cleaning • Ballasting • BCM • Grinder • Resurfacing • Spot Resurfacing

System Operating Parameters / 2019 PCAR 22 Aurizon Network 2019

• Undercutting

As per the NSAP model, a 1% increase in tonnes delivered equates to an approximate increase of 0.49% in the tonnage dependant maintenance. This scaling has therefore been applied as an extension to activity durations of the above products to reach contract tonnes from that delivered in calendar year 2018.

Table 5: Tonnage dependent activity increase

System Operating Parameters / 2019 PCAR 23 Aurizon Network 2019

4.1.5 System Closures The number of system closure hours in years subsequent to 2018 are substantially less across the four systems. This has been as a result of a concerted effort to compress scope and maximise efficiency where possible for FY20. It is assumed that the increased scope in each system in future years (due to increased tonnes) will increase the closure durations to no more than the closure hours in 2018.

The following system shuts are included in the Capacity Assessment.

Table 8: System closure hours per system

Month Blackwater Goonyella Moura Newlands Jan 12 12 10 24 Feb 12 12 11 24 Mar 36 24 12 24 Apr 36 36 36 24 May 36 16 24 Jun 12 Jul 24 58 24 Aug 24 48 12 108 Sep 48 48 60 Oct 58 24 12 54 Nov 48 24 12 21 Dec 36

The majority of tonnage dependant activities conducted in the Newlands and Moura systems take place in their respective system closures, they have therefore been scaled by the same ratios of the tonnage dependant maintenance activities (Newlands 34.18% and Moura 18.59%) to reach a contract tonnage state.

This has resulted in an additional 41hrs and 77hrs of system closure hours in the Moura and Newlands systems respectively.

System Operating Parameters / 2019 PCAR 24 Aurizon Network 2019 4.2 Moving maintenance activities In addition to the fixed activities that require possessions for the work to be undertaken there are moving activities that are undertaken to: • Inspect the infrastructure • Transport material or work trains to / from site • Perform maintenance on the move (i.e. grinding)

To establish the amount of moving activities to incorporate within the Capacity Assessment a review was performed of 2018 records. Historical maintenance train data was sourced from the Vizirail Datawarehouse for a period of 1 calendar year – 01/01/2018-31/12/2018. The 3205 train services are maintenance trains moving or working between locations and does not include on track machinery movements within maintenance possessions.

A summary of the services identified through the analysis is provided in Table 9 below.

Table 9: Maintenance moving activities service category

Maintenance moving activities Service Category Proportion of services Resurfacing and Lining (MMA070/MMA500/MMA501) 40%

Ballast Train 8%

Others (Sleeper, track laying, Track Geometry, Tuition, Scissor & unidentified) 19%

System Operating Parameters / 2019 PCAR 25 Aurizon Network 2019 5 Network Planning

This section of the System Operating Parameters refers to the activities undertaken to:

• Plan non-coal (MaTP) traffic • Plan maintenance and renewals • Provide available capacity information for the scheduling of services 5.1 Non Coal (MaTP Services)

The provision of capacity for Non-Coal trains on the CQCN is a legislative requirement of the Transport Infrastructure Act (TIA) 1994. The TIA specifies the minimum number of train paths to be made available to Non- coal services. Non-coal trains are typically included in the Master Train Plan (MaTP) developed in conjunction with Queensland rail for services operating on the NCL.

The MaTP contains the following types of traffic:

• Livestock • Passenger: o o Sprit of Outback o • Freight • Light Engine1

To ensure that the Capacity Assessment is based on an adequate representation of Non-coal traffic the MaTP has been compared to the TIA requirements. Where it was found that the MTP had less trains operating than in the TIA additional trains were added to the simulated MaTP.

5.1.1 Seasonal traffic

Seasonal grain traffic is not included in the MaTP. 5.2 Alignment with supply chain interfaces All port and mine maintenance and renewal activities are assumed to occur in alignment with network closures and other network activities. I.e. – there is no capacity loss assumed with these activities when undertaking Capacity Assessments and coal is assumed to be available at the mine.

1 Paths to facilitate Light Engine movements are not preserved under the TIA

System Operating Parameters / 2019 PCAR 26 Aurizon Network 2019 5.3 Pathing Plan

The AN Tactical Planning team develop pathing plans to advertise the paths that are available for Access Holders to operate trains on. These are based on the constraints from MaTP services, possessions and moving products. This approach is replicated in the Capacity Assessment as described below.

5.3.1 Network Pathing

A base template for train paths is developed for each system based on the achievable headway through each component as described in Table 10 below.

Table 10: Model Pathing. Section Empty Separation Loaded Separation

Newlands

Abbot Point – Pring Headway separation Demand basis for port availability

Pring – Birralee 36 minutes – fixed times Headway separation

Goonyella

Hay Point – Jilalan Headway separation Demand basis for port availability

Jilalan – Coppabella 20 minutes – fixed times 20 minutes – fixed times

Coppabella – Gregory Jct Headway separation Headway separation

Coppabella - Wotonga Headway separation Headway separation

Blackwater

Callemondah – Bluff1 15 minutes – fixed times 20 minutes – fixed times

West of Bluff Headway separation Headway separation

Moura

Callemondah – Dumgree2 90 minutes – fixed times Headway separation

This differs from the pathing templates used by the tactical planning team in the following respects:

• Newlands System Capacity Assessments assume that RCS has been implemented through the Newlands system resulting in a lower path separation than currently used.

System Operating Parameters / 2019 PCAR 29 Aurizon Network 2019 6 Operator planning and logistics 6.1 Train Operation 6.1.1 Fleet Size

The modelling process seeks to ensure that all demand is met, therefore the quantum of rolling stock modelled may differ from that operated in each system. When undertaking a Capacity Assessment Aurizon Network adjusts the quantum of rolling stock to meet the demand requirements. This is primarily because the fleet sizes each operator may have in each system may not match that required to meet the demand scenario considered in the Capacity Assessment

The number of trains used for the Capacity Assessment will be published in the relevant Capacity Assessment report.

6.1.2 Payloads Because Aurizon Network provides capacity in terms of TSEs (rather than tonnes), any increase in payload beyond contract assumptions, will not have any impact on network capacity, unless that increase in payload results in consumption of an additional path or changes the interface parameters. The Capacity Assessment is therefore performed to understand if the number of Train Service Entitlements (TSEs) can be achieved.

Payloads from Schedule F of UT5 are used to convert the TSEs into mtpa for information purposes in the Capacity Assessment.

System Operating Parameters / 2019 PCAR 30 Aurizon Network 2019 6.2 Cycle description The ability of Network infrastructure to deliver Access Holder demand depends on the design of the above rail operation. This operation is included within the capacity assessment to enable the planned operation to be tested.

Typically, operators generally plan and operate to the following cycle in the CQCN:

• Train departs home depot

• Crew change at designated point

• Arrive mine and load train

• Crew change at designated point

• Arrive port and unload train

• Return to home depot

• Relieve crew

• Provision train for next journey

• Undertake any train inspections, maintenance and shunting

Aurizon Network sources information relating to each operator’s cycle from the relevant Operating Plan supplemented with information from scheduled operations. This interpretation of the cycle is provided in each operator specific appendix which includes:

• Cycle Description Description of the train cycle including crew changes, operations in yards and other activities en-route

• Interface times: The times used for interface locations (load / unload)

System Operating Parameters / 2019 PCAR 31 Aurizon Network 2019 7 Network Scheduling

This section of the SOP describes how Coal train services that operate within the CQCN are scheduled within the Capacity Assessment. This includes:

• The demand • How rolling stock is assigned to meet demand 7.1 Demand

The CQSCM is a discrete event simulation model used to generate schedules using business rules based on the demand entered. This demand, entered as TSEs is

• Converted into a number of train orders required • Scaled by the number of days in the month. Demand used in the Capacity Assessment is provided in the relevant Capacity Assessment report. 7.2 Dispatching

During the simulation the train orders are injected into the CQSCM Dispatcher. The dispatcher is a queue based management system that registers the orders and allocates them to available trains. The dispatcher prioritises orders to maximise order fulfilment equally across all demand

Within the CQSCM’s Dispatcher, several sub-processes are executed to determine if a train accepts the order and commences its service. To enable a successful allocation of an order to a train to form an active service, all sub- processes must successfully complete.

These are:

• Availability of Network Paths This process controls the Network Path allocated to a train. When a Network Path is available, the Dispatcher reserves the Network Path for the train and continues to evaluate the other sub-processes. In the event a network path is not available, train orders are not processed and are queued.

• Train Configuration applicability This process checks to ensure the train configuration is suitable for the available order. In some cases, there are restrictions on the train configurations such as Electric trains operating to non-electrified origins.

• Train Loadout management This process predicts the trains arrival time at the mine to ensure the loadout is available to accept the train. The availability of the loadout is evaluated to minimise train delays at the loadout.

• Route availability This process evaluates the availability of the track network to ensure the train can reach its origin mine. In the event an outage on the network is encountered, the Dispatcher will prevent the service from being created and seek to find a suitable time that aligns track network and mine availability.

• Empty direction Prior to dispatching a train service from the origin, the model looks forward in time. This determines if the train service is able to traverse the track to the destination load out without being blocked by a closure or track possession. If the model detects that one of these two events will block the train from reaching its destination, the train service will not dispatch.

System Operating Parameters / 2019 PCAR 32 Aurizon Network 2019

The model continuously re-evaluates to dispatch a train service. This method will see that trains depart their respective service origin to arrive at the section under closure or possession at a point in time when the track becomes available.

The look ahead function in the model utilises reference train SRTs and considers scheduled dwells such as crew changes. Variation to SRTs and contracted dwells is not considered in this method. Based on this approach the model may dispatch a train service in the empty direction that will be blocked by a closure or possession, dependant on the variation levels entered.

Network paths are also considered and managed in the Dispatcher for the mainline corridor.

• Loaded direction Train services departing the mine assess the availability of the track up to the next point of capacity (i.e. signal or passing loop). Using this method in the model, train services will proceed along their route to the identified separation location where trains dwell for network paths.

Once a train arrives at the separation point, a network path is allocated to a train. Trains will dwell at the separation location until the network path time is reached and will then continue the journey to the destination port.

During the trains journey, the train continues to assess the track sections being traversed to ensure the network is available. In the event congestions or an outage is reached, trains will proceed once the following sections and/or queued trains have cleared.

The dispatcher seeks to fulfil demand equally across all contracts by prioritising those that have achieved the smallest proportion of their demand during the simulation period.

System Operating Parameters / 2019 PCAR 33 Aurizon Network 2019 8 Train Operation

This section of the System Operating Parameters describe how the Capacity Assessment replicates the operation of trains across the CQCN through:

• Network Control • Speed of trains (speed restrictions) • Day of Operations loss • Force Majeure 8.1 Network Control The management of a trains journey in the CQSCM is handled through a Track Control process. The purpose of this process is to continuously monitor the situation of trains on the track network and determine the next possible moves similar to that of a Network Controller operating trains, including.

• Manage conflicts at a nodal level to pass trains at crossing locations • Manage the route set ahead to avoid deadlocks • Manage the routing of trains around maintenance being undertaken on the track network • Manage the trains entire journey to ensure its cycle is completed • Manage activities in yards and allocation of roads in a yard • Manage safe-working and headway constraints of the track network 8.2 Temporary Speed Restrictions (TSRs)

To replicate the impact of TSRs on the rail network, historical data for the CQCN for 1/1/18 to 31/12/18 was analysed. This information was used to generate a set of representative speed restrictions through the following process:

• Collate historical speed restrictions Records of the location, duration and speed limit imposed across the CQCN were collated for a 12 month period

• Determine time impact The impact of the TSR was determined by calculating the additional time taken to traverse the speed restriction length (including decelerating and accelerating) compared to the time taken to cover the section without speed restrictions applied.

System Operating Parameters / 2019 PCAR 34 Aurizon Network 2019

Figure 9: Assumed impact to train speed used to calculate TSR impact to SRT • Inclusion in the Capacity Assessment A table was generated that identified for each TSR the:

• Location • Track • Start Date / End Date • Time impact

Table 15 to Table 18 illustrates the typical speed restrictions (total minutes) applied on each branch of the CQCN systems in the Capacity Assessment. The impact of these speed restrictions is dependent on the amount of traffic operating over each speed restriction.

8.3 Network caused Day of Operations Losses

Day of operations losses result from a number of varying influences, which include (but are not limited to):

• Adverse weather conditions (excludes those declared as Force Majeure) • Infrastructure faults and failures • Incidents at interfaces (e.g. level crossing incidents, trespassing)

These can manifest in the DOO as delays and failures. To represent this, the operating logic in the dynamic model randomly applies cancellations to 10% of empty train services scheduled to depart the origin. 8.4 Force Majeure

Force Majeure Events are not included in the Capacity Assessment, which is in accordance with all Access Agreements whereby obligations are suspended during a Force Majeure Event.

System Operating Parameters / 2019 PCAR 38 Aurizon Network 2019 9 Information 9.1 Train Service Entitlements

Aurizon Network provides capacity in the form of TSEs i.e. the provision of the ability for an Access Holder to operate a specified number and type of train services between a mine and a port. Aurizon Network determines the number of TSEs that are required to be contracted based on throughput and payload assumptions provided by the Access Seeker in the COP. Two TSEs are required for cyclic traffic, one for the empty leg and one for the loaded leg.

The derivation of TSEs from a tonnage is described below:

Table 19: Train Service Entitlements calculation Table.

Value Source / Calculation

million tonnes per annum (MTPA) Access Holder / Seeker Train payload (tonnes) Access Holder / Seeker Annual TSEs = 2 * (MTPA / Payload) Monthly1 TSEs = Annual TSE / 12 The agreed TSEs are included in the Access Agreement.

1 Rounding of fractional part of TSE calculation based on method described in section 0

System Operating Parameters / 2019 PCAR 39 Aurizon Network 2019 9.2 Measurement of capacity 9.2.1 Monthly scaling

To ensure there is sufficient network capacity to service existing and future contracts TSEs are tested in the dynamic Capacity Model based on a 30 day month with adjustments made for non 30 day months. Once scaled for the non-30-day months adjustments are made as per the following:

• if the remainder of TSEs are less than or equal to 0.29, then round down • if the remainder of TSEs are greater than 0.29, then round up

9.2.2 Pass / Fail criteria Capacity Assessments are assessed on a monthly basis to determine if the demand can be met for each month.

• Each mine / port combination must achieve all TSEs in each month of the simulation

• Capacity is limited at the worse performing month.

Capacity

Available Capacity is determined as the over achievement of demand through the simulation. This Available Capacity is illustrative only as does not take account of the specific demand which may be required. Specific scenarios can be initiated by Access Seekers through the Access Request process.
