www.asa.transport.nsw.gov.au

This technical note is issued by the Asset Standards Authority (ASA) to notify updates to

T MU AM 01008 ST Technical Maintenance Plans and Coding System, version 2.0.

The following changes apply:

1. Section 2.1. Scope Section 2.1. Scope is replaced with the following content:

This standard establishes the requirements of a TMP and associated framework for TMCs for

TfNSW owned assets. This standard defines the framework for TMCs required to be used in the

development and maintenance of maintenance plans assigned to both new and existing asset

types. This standard also defines how:

• to identify the need for a new TMC

• TMCs are structured and grouped within the framework

• to request a new TMC when developing a new or modifying an existing maintenance plan

(developing a new TMP may result from modifying an existing TMP due to service schedule

variations as part of a configuration change)

The details of TMCs covering various disciplines are published on T MU AM 01009 TI Technical

Maintenance Coding Register. It is intended that similar information for all engineering disciplines

and other modes will be published in a future release of this standard. In the interim contact the

relevant ASA discipline lead engineer for those discipline TMCs not covered in the current

release of the register.

Maintenance within the scope of this document refers to both routine maintenance and renewals

maintenance.

Preface The Asset Standards Authority (ASA) is an independent unit within Transport for NSW (TfNSW)

and is the network design and standards authority for defined NSW transport assets.

The ASA is responsible for developing engineering governance frameworks to support industry

delivery in the assurance of design, safety, integrity, construction, and commissioning of

transport assets for the whole asset life cycle. In order to achieve this, the ASA effectively

discharges obligations as the authority for various technical, process, and planning matters

across the asset life cycle.

The ASA collaborates with industry using stakeholder engagement activities to assist in

achieving its mission. These activities help align the ASA to broader government expectations

of making it clearer, simpler, and more attractive to do business within the NSW transport

industry, allowing the supply chain to deliver safe, efficient, and competent transport services.

The ASA develops, maintains, controls, and publishes a suite of standards and other

documentation for transport assets of TfNSW. Further, the ASA ensures that these standards

are performance-based to create opportunities for innovation and improve access to a broader

competitive supply chain.

This standard provides information regarding the requirements for the application of a technical

maintenance code for all assets owned by TfNSW. This standard sets the requirements of a

technical maintenance plan (TMP) and associated framework for technical maintenance codes

for TfNSW owned assets.

This standard is a second issue. The changes from the previous version include the following:

• minor formatting change

• minor updates to tables

1. Introduction The Assets Standard Authority (ASA) is committed to effective and efficient management of

Transport for New South Wales (TfNSW) assets. The ASA is collaborating with other

government and non-government organisations to continuously improve the capability,

performance and condition of the assets over the full life cycle.

The technical maintenance plan (TMP) specifies the maintenance plan required for TfNSW

owned infrastructure and fleet assets. The TMP provides a comprehensive list of all the

preventive maintenance service schedule requirements specified for a specific asset type in

accordance with a technical maintenance code framework.

This standard defines the requirements of a TMP and associated framework for technical

maintenance codes for TfNSW owned assets. These requirements will ensure standardised

coding practices are applied.

The ASA expects to develop and publish a series of technical maintenance codes relevant to

each mode of transport and asset class for use by Authorised Engineering Organisations (AEO)

and service providers.

2. Purpose The objective of this document is to inform stakeholders of the requirements of a TMP and

associated framework for technical maintenance codes for TfNSW owned assets.

This standard specifies the framework for technical maintenance codes (TMCs) owned by

TfNSW as defined within the TMP. The standard also refers to a published register containing

approved TMCs.

Assets owned by TfNSW shall have their maintenance plan defined within the TMP by asset

type aligned with a TMC.

2.1. Scope This standard establishes the requirements of a TMP and associated framework for TMCs for

TfNSW owned assets. This standard defines the framework for TMCs required to be used in the

development and maintenance of maintenance plans assigned to both new and existing asset

types. This standard also defines the following:

• how to identify the need for a new TMC

• how TMCs are structured and grouped within the framework

• how to request a new TMC when developing a new or modifying an existing maintenance

plan (developing a new TMP may result from modifying an existing TMP due to service

schedule variations as part of a configuration change)

The details of TMCs provided in Section 9 and Section 10 of this document are currently for

heavy rail, covering the electrical and signalling and control system disciplines. It is intended

that similar information for other engineering disciplines and other modes will be published in a

future release of this standard. In the interim, contact the relevant ASA discipline lead engineer

for those discipline TMCs not covered in this standard and supporting register.

Maintenance within the scope of this document refers to both routine maintenance and

renewals maintenance.

2.2. Application This standard applies to TfNSW, transport cluster agencies, AEOs and service providers

performing asset management related services to TfNSW, including their suppliers involved in

developing new or modified TMPs for TfNSW owned new or altered assets or systems. This

standard shall be applied during all phases of the asset life cycle.

The standard also applies to the asset register (creation and management of assets in

accordance with the asset classification structure – defined in the T MU AM 02001 ST Asset

Information Management) and the associated planning, scheduling and execution of preventive

maintenance service schedules (defined in the TMP) required to be undertaken by maintenance

AEOs. Refer to the T MU AM 02001 ST for further information on asset register requirements.

4. Terms and definitions The following terms and definitions apply in this document:

AEO Authorised Engineering Organisation

ASA Asset Standards Authority

asset is an item, thing or entity that has potential or actual value to an organisation. Physical

assets usually refer to equipment, inventory and properties owned by the organisation. Physical

assets are the opposite of intangible assets, which are non-physical assets such as leases,

brands, digital assets, use rights, licences, intellectual property rights, reputation or agreements.

asset life the period from asset creation to asset end-of-life (disposal)

asset system set of assets that interact or are interrelated

asset type identifies the variation of assets that fulfil the same asset function. An asset type will

have characteristics that distinguish them separately from other asset types within an asset

function (different technical specification or different construction). The difference in

specification within an asset type including variations in make and model is identified by the

Technical Maintenance Code (TMC).

availability the measure of the percentage of time that an item or system is available to perform

its designated function

conditional failure A defect is a conditional failure when it has the potential to become a

functional failure and occurs when the asset condition is outside a maintenance threshold but it

is still able to perform its function and does not yet have operational consequences (may need

to be monitored as part of condition assessment or repaired).

functional failure a defect is a functional failure, when the equipment cannot fully perform its

design function and causes immediate operational consequences such as train delays or loss of

power (subject to the level of available redundancy)

life cycle stages involved in the management of an asset

maintainability a characteristic of design and installation, expressed as the probability that an

item will be restored to operating condition, within a given period of time, using prescribed

procedures and resources

reliability the probability that a specified item will perform a specified function within a defined

environment, for a specified length of time

renewals maintenance includes the cyclic renewal and upgrading of assets (including

component and asset overhaul) to avoid deterioration in their condition to ensure long term

asset performance and financial sustainability. Renewals maintenance is also referred to as

capital maintenance or major periodic maintenance (MPM).

routine maintenance is a collective of all preventive and repair activities excluding renewals. It

includes planned inspections, preventive maintenance, corrective maintenance and emergency

response to ensure the safety and reliability of assets. Routine maintenance is also referred to

as recurrent maintenance.

rotable spare item replaced during corrective and breakdown maintenance or refurbishment

which are repairable, and are returned to stock for reuse if economically viable to repair

TMC technical maintenance code; the TMC is used to identify the variation of unique technical

specifications for an asset type. Assets are assigned a TMC to reflect its configuration based on

the asset type and specification and to define the applicable maintenance plan.

TMP technical maintenance plan; a TMP defines the maintenance plan applicable for an asset

(assets are associated with their required maintenance plan by the TMC). The TMP defines

what maintenance tasks are to be performed (packaged as service schedules), when

(frequency, conditional or statistical trigger) and where the maintenance tasks are to be

performed including required materials, consumables and tools and equipment.

5. Maintenance concept The maintenance concept shall facilitate the achievement of the following maintenance

objectives in a cost effective manner:

• assure the continued safety and reliability of the system

• maximise availability

• minimise service disruptions and delays as a result of asset or system defects

The development of the maintenance concept during the planning stages assures that the

functions of design and support are integrated with each other and aimed towards the same

maintenance goals. This prevents individual components of the system reflecting different

design approaches, which can cause incompatibility and increase support costs.

Asset maintenance shall be safety and reliability centred due to the immediate impact that most

single point failures could have on the network and the ability to ensure safety to passengers,

personnel or public at large. Due cognisance shall be taken of this fact when developing the

maintenance support structure. The maintenance concept should be considered as a dynamic

statement which will progressively change over time to reflect the evolving design solutions,

changes in the maintenance environment and business objectives. The maintenance concept is

related to and driven by the operational concept.

The maintenance concept shall provide the basis for establishing supportability requirements

during the design phase of system configuration changes and the establishment of

requirements for total logistic support, including the determination of the following:

• maintenance tasks

• task frequencies and times

• personnel and skill levels

• test and support equipment

• spare parts

• packaging, handling, storage and transport

• facilities

• technical data

5.1. Levels of maintenance Maintenance of TfNSW assets are carried out at two levels – on-system and off-system.

At both levels, the maintenance is performed on the basis of time, operation, usage driven, on

condition (measured or monitored) and by the correction of conditional or functional failures.

Where replacement is by a rotable item, the rotable item is generally repaired at level 2

off-system.

For each type of asset, the criteria for scheduling preventive maintenance are set out in the

TMP. The specific tasks to be carried out are set out in the service schedules. The results of

maintenance activities and any corrective actions taken shall be recorded in the AEO's asset

information system.

5.1.1. Level 1 – On-system operational maintenance In general, assets are maintained on-system. This maintenance is arranged or carried out by

maintenance AEOs.

Assets are accessed for maintenance either by reducing system capabilities such as failure

tolerance, traffic speed, or suspending operations and providing alternate transport for

customers. Such arrangements shall be limited to very short durations outside of peak service

times. When it is necessary to close one or more tracks for maintenance (track possession), this

shall be arranged through the track possession system.

On-system maintenance, which is conducted on the system in the field, includes preventive

maintenance, corrective maintenance and modifications, upgrades, refurbishments and new

installations.

Preventive maintenance consists mainly of two forms:

• short duration surveillance tasks conducted during peak traffic periods

• lengthier preventive service or surveillance tasks at other times

Corrective maintenance consists of three forms:

• immediate corrective maintenance which is conducted immediately on notification to, or

discovery by maintenance staff – conditional failures

• call out corrective maintenance (breakdown maintenance), outside normal shift times,

which is attended to by staff called out from home or staff on standby – functional failures

• follow-up corrective maintenance which is undertaken to rectify any temporary repairs

previously completed or to undertake corrective maintenance for those conditional failures

found during preventive maintenance that did not require immediate repair

Modification, upgrades, refurbishments and new installations may be carried out by either

maintenance staff or construction staff depending on task requirements.

On-system operational level restoration of function shall generally be by replacement of

configuration items or parts thereof, or by replacement of consumables, or by the adjustment of

out of tolerance parameters.

5.1.2. Level 2 – Off-system facilities maintenance If specialist facilities are required and it is more cost effective to take the equipment off-system,

certain asset items shall be maintained at accredited specialised facilities operated by

contractors or by the original equipment manufacturer (OEM).

Workshop level maintenance such as a complete overhaul or extensive repair shall normally be

conducted off-system on major asset items. It shall be performed in workshops that are

recognised by the maintenance AEO and are specialised workshops (repair facilities) which

have the throughput to justify the necessary support equipment and quality systems.

Off-system facilities depot level repair shall include servicing tasks and internal parts

replacement and tasks requiring limited support equipment and non-specialised skills.

Workshop level repair shall include the repair or overhaul of configuration items to the deepest

level possible while remaining cost effective. Repair and overhaul shall be completed in

accordance with approved specifications and standards.

6. Technical maintenance plans TMPs are sets of preventive and surveillance maintenance plans designed to ensure the asset

(maintainable configuration item) will continue to operate within design tolerances to meet

performance outcomes. The TMP is developed as an output of the maintenance requirements

analysis (MRA). Refer to T MU AM 01002 MA Maintenance Requirement Analysis Manual for

MRA information.

The TMP shall include as a minimum the following information:

i. what maintenance is carried out (required tasks and associated maintenance actions

including reference maintenance and operating manuals)

ii. when maintenance is carried out (frequency of servicing – time, condition, event, statistic –

defined set of tasks)

iii. why maintenance is carried out (reference for traceability to requirement)

iv. where maintenance is carried out (maintainable item – make, model, type of equipment) –

this is the link to the asset type (configuration item)

The TMP does not include the following information:

v. who maintains (resources, competencies – allocated via preventive maintenance

scheduling process)

vi. how maintenance will be carried out (in accordance with AEO processes and procedures)

AEOs shall develop TMPs for existing and new type approved assets in accordance with

T MU AM 010003 ST Development of Technical Maintenance Plans.

Items in i. to iv. (standard) are owned by TfNSW with the ASA being the custodian.

Items in v. and vi. (procedures and processes) are owned by the AEO.

The TMP is one element only of a comprehensive approach to asset management. Asset

management philosophy is based on achieving specified service requirements (such as safety,

reliability and sustainability) associated with an asset at minimum cost of ownership through the

whole asset life cycle.

6.1. Candidate assets included in the TMP Any item that contains one or more of the following features shall be allocated a TMC and have

a TMP:

• is repairable

• is used for zonal maintenance (patrols and examinations) covering multiple similar assets

or systems

• has a defined maintenance plan, that is, the item has a scheduled maintenance activity at a

defined interval – based on time, condition, event or statistic trigger

• requires some special maintenance management activity and thus requires certain

information to be recorded

6.2. Application of TMPs TMPs shall ultimately allow work to be rationally planned and provide the basis of a

maintenance scheduling and work order system.

Maintenance is required to be programmed in accordance with the latest update of the TMP and

maintenance tasks are carried out in accordance with the associated service schedules, which

are published for each relevant TMC.

New or modified TMPs once approved as per the requirements of the T MU AM 01003 ST

Development of Technical Maintenance Plans shall be fully implemented within six months from

the date of approval.

The TMP service schedules, otherwise known as maintenance actions, shall be carried out at

periods based on assets in fair and reasonable condition in an operating environment of a

reasonable standard, and with a normal level of usage across the network.

Service schedules shall contain a planning latitude which reflects the allowed variation around

the due date; that is, the earliest start date and latest finished date. Planning latitudes shall be

20% for service schedules of 42 days or less and 10% for service schedules greater than

42 days unless otherwise stated in the TMP. A planning latitude shall be defined for each TMC

service schedule within the TMP.

Service schedules shall contain a classification to identify it as being safety critical, safety

significant or reliability as per the requirements and criteria defined in T MU AM 01004 ST

Routine Maintenance Service Schedule Classification and Compliance. A classification shall be

defined for each TMC service schedule within the TMP.

The periodicity and operational triggers specified in the TMPs are the maximum periods, based

on average usage and operational conditions. These periods can be varied to compensate for

local conditions, such as above average usage, difficult maintenance window or access, and

environmentally unfriendly conditions, with the decision to vary from the recommended period

being based on local knowledge and economics. The rationale for change shall be included in

appropriate maintenance analysis documentation. Any change of periods in TMP requires

approval by AEO’s authorising officer.

Additional maintenance actions and reduced maintenance periods shall be directed by the

maintenance AEO as appropriate to meet as needed local conditions. Local conditions shall be

monitored and documented by maintenance staff and additional maintenance shall also be

directed as required to particular locations at times of vulnerability. For example, at times of

construction or mechanised maintenance activities at a site or at locations experiencing

vandalism or where the operating environment has degraded and is imposing greater wear or

loads on the assets.

Changes to approved existing TMPs such as change of service schedule tasks, frequency and

latitude shall be managed, approved and published as per the requirements defined in

T MU AM 01003 ST Development of Technical Maintenance Plans. A revision number shall be

applied to ensure the correct version is published as well as to provide a revision history listing

the changes applied.

Perceived errors in the content of the TMP shall be made in writing via email to

[email protected].

6.3. TMP layout The TMP layout identifies the asset (configuration item) and its maintenance plan.

The layout shall contain the following fields:

• the TMC – structured code up to 6 levels

• name – applied at each of the TMC levels

• manufacturer – name and reference, applied at the assembly or subassembly – usually at

level 4 or level 5

• on-system maintenance details

• publication reference and notes

Figure 1 provides and illustrative example of a TMP layout:


Figure 1 – Example of a TMP

6.4. TMP field 1 – TMC The TMC provides for a unique code that describes the configuration items within an

application, which satisfies the candidacy criteria in Section 6.1. The code is a hierarchal

structure with a maximum of 6 levels as described in the TMC framework in Section 7.

6.5. TMP field 2 – Name TMP field 2 shall contain the name of asset or configuration item. The name used shall be,

wherever possible, the name used by the manufacturer as it appears on the configuration

control documents (accepted abbreviation may be used to fit the available space). Generic

names may be used if configuration control documentation is not available.

6.6. TMP field 3 – Manufacturer – name and reference TMP field 3 shall contain the prime manufacturer of the item. This shall not be confused with the

supplier.

6.7. TMP field 4 – On–system maintenance details The first column contains the service schedule identifier. This shall be recorded on the

maintenance work order.

The second column shall contain the periodicity and allowable scheduling latitude of the service

schedule (for example weekly, monthly or yearly).

The third column shall contain operational and event conditions for the service schedule. For

example:

• performed on condition – replace transformer oil

• performed on event – post feeder trip – sustained fault, post flood, three fault openings

6.8. TMP field 5 – Publication reference The publication reference refers to the reference number and description of the service

schedule.

7. TMC framework The TMC provides for a unique description of configuration items within the application, which

satisfies the candidacy criteria in Section 6.1. The code is a hierarchical structure with a

maximum of six levels described as follows:

• Level 1 Application – Code of two alphas which describes the application. For example,

'SC' for signalling and control systems.

• Level 2 System – Number which is a two numeric code allowing up to 99 systems to be

identified within an application.

• Level 3 Subsystem – Number which is a two numeric code allowing up to 99 subsystems

to be identified within a system. In some subsystems this level is used to group asset

functions with similar maintenance requirements.

• Level 4 Assembly – Number which is a two numeric code allowing up to 99 major

assemblies to be identified within a subsystem. This level provides information on the

differing technologies and type of asset in the system which provides essentially the same

function. This is the level associated and linked with the asset defined in an asset register

and shall be used to define a specific make, model or type of assembly that fulfils a

function within a subsystem. See Section 8 for details regarding the TMC link with the

asset register and asset classification.

• Level 5 Subassembly or item – Number which is a two numeric code allowing up to 99

items (components) to be identified within a major assembly.

• Level 6 Item – number used where level 5 is used to identify a subassembly. It defines the

item (component) within the subassembly.

The TMC shall typically be a 10 character code (based on the concatenation of level 1 to

level 5) with 12 characters allowed only when level 6 is defined.

The TMC is used to identify the unique technical specification for an asset type within the

framework and to identify and assign the asset type within an application, system, subsystem

and assembly based on its configuration and function.

The TMC framework caters to group assets of the same asset type to allow for variation in

manufacturers, specifications and components.

The TMC links the technical specification of the asset type with the asset in the asset register as

well as defining a list of general components used to help identify the item or part that is to be

inspected, serviced or repaired on a work order.

The TMC once allocated for use shall not be reused. TMCs shall be reserved for new assets

planned or when modifications are being planned that alters existing asset configurations.

7.1. TMC application groups TMC level 1 application groups have been defined to cover both network infrastructure and fleet

assets by engineering discipline or by fleet class.

Infrastructure assets shall have a TMC associated with one of the following application groups

as shown below in Table 1.

Table 1 – TMC application groups for network infrastructure

Level 1 TMC description

EP For electrical assets (substations, distribution, overhead and electrolysis). Refer to Section 9 for more details.

SC For signalling and control assets and systems. Refer to Section 10 for more details.

7.2. Purpose of the TMC Asset identification and coding is generally established during the acquire stage of the life cycle

and will continue to be applied throughout the operate and maintain stage. Coding is required to

uniquely identify the assets for a range of purposes.

The TMC forms the basis of the numbering system used for the following purposes:

• group, categorise and define maintenance plans (preventive maintenance service

schedules) by asset type based on an reliability centred maintenance (RCM) analysis

(different asset types within the same function may adopt the same TMP)

• group and categorise asset types (configuration items) within an asset register

• ensure the application of maintenance plans and reporting of maintenance compliance for

all assets are contained with the asset register

• as a primary reference for configuration documents such as drawings, specifications as

well as derived documents such as TMPs, maintenance analysis documentation, failure

and defect coding

The TMC also shall define the following:

• component and sub-component parts required to support failure and defect identification

and management (component and sub-components are not directly associated to the each

asset but are linked via the asset type that defines a common parts list for all assets of that

type)

• warranty to be applied

• materials list (inventory) required for servicing, maintenance and repairs

The TMC defines the system down to six levels which includes systems, subsystems,

assemblies and items that make up the complete system. This specification provides a

description of asset types (configuration items) from the 4th level to the 6th level of the TMP.

The 4th level to 6th level breaks down the asset to manufacturer and component levels.

7.3. Requesting a new TMC TfNSW are the owners of the TMPs and associated TMCs. ASA is the custodian on behalf of

TfNSW and as a result controls and manages the published register of approved TMCs for use

across the transport network.

A TMC shall be requested when developing a new or modifying an existing maintenance plan. A

new TMP may result from modifying an existing TMP due to service schedule variations as part

of a configuration change.

The request for a new TMC shall align with the framework developed for each discipline as

detailed in later sections of this document. Requests shall be made in writing via email to

[email protected].

8. TMC link with the asset register and asset classifications All assets shall be classified by class, function and type as defined in T MU AM 02001 ST. The

asset function shall be used to group one or more asset types that perform the same function.

The TMC shall be used to define the unique make, model or type (technical specification) that is

linked to an asset type for an asset performing a designated function. There can be one or

many TMCs that exist for an asset type that are approved for use on the transport network.

The asset type shall be a separate identifier recorded against the asset in the asset register.

These assets have common characteristics which distinguish them separately and need to be

managed as a unique configuration item.

The TMC shall be a separate identifier recorded against the asset in the asset register. Only

one TMC shall be recorded against the asset in the asset register. The TMC shall remain

recorded against the asset in the asset register for historical purposes even after all assets of

that type have been disposed and no longer exist on the transport network.

The TMC framework caters to group assets of the same asset type to allow for variation in

manufacturers, specifications and components. Figure 2 shows the asset register linked to the

TMC and Table 3 provides details and examples of asset association.

10. TMCs – Signalling and control systems The TfNSW signalling and control system assets comprise the following vital and non-vital

system assets.

The vital system assets are:

• signals

• trainstops

• track circuit train detection systems

• point operation and detection systems

• traction (electrical current) return arrangements

• vital interlocking systems and protected level crossing systems

• automatic train protection (field equipment)

The non-vital elements of the signalling system that support and interface to the vital system,

includes:

• control systems, such as the advanced train running information control system (ATRICS),

which are part of a consolidated train control centre

• control and indication panels for signallers

• the track side components that provide information to remote indication systems used for

management and train control purposes

• control systems that are part of a consolidated train control centre inclusive of SigView, the

Wollongong train describer (WTD), train location systems (TLS) and all forms of ATRICS

• high voltage transmission, distribution, rectification and control of electric power for

purposes of supplying electric trains, electrical supply to the railway signalling system,

electrical supply to commercial and industrial buildings and other applications (includes

workshops, railway stations, offices, lifts and escalators, trackside infrastructure buildings

and tunnel pumps)

The following sections contain the TMC groupings to level 3 (subsystem). The TMCs within

each group down to level 4 and level 5 are contained within T MU AM 01009 TI.

10.1.6. SC06 – Automatic train protection Automatic train protection (ATP) is a safety system that relays signal, track speed and other

track data to trains. It provides a safety net to drivers by preventing trains from significantly

exceeding track speed and by ensuring safe speeds when approaching signals at stop. If

speeds are too high, in both situations the ATP system intervenes by applying the train’s

brakes. Also, drivers will be warned before a speed limit is exceeded and in most cases before

a limit of authority is overrun.
