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.

TfNSW has identified an absence of nationally recognised qualifications or competency

standards for certain specialised functions within the railway signalling discipline. It has also

identified the need to assist the Authorised Engineering Organisations (AEOs) in articulating

and assessing the competency of their personnel on certain signalling systems and functions

that are carried out on the TfNSW Transport Network.

This standard has been developed in response to this identified need and sets the generic

competency requirements for personnel to be recognised as competent to perform functions

within the signalling discipline on the TfNSW heavy rail network.

This document has been approved by the ASA Configuration Control Board and is a first issue.

1. Introduction Every Authorised Engineering Organisation (AEO) has a responsibility to ensure that

engineering activities carried out by an AEO on behalf of TfNSW are performed by suitably

trained and experienced personnel, that is, personnel designated as being 'competent' persons.

This is important to meet the legislative and regulatory obligations of the Rail Safety National

Law 2012, AS 4292.1 Railway Safety Management - General Requirements, Work Health and

Safety Act 2011 and the requirements stated in T MU MD 00009 ST AEO Authorisation

Requirements.

This standard sets the generic competency requirements for the designing and commissioning

functions within the signalling discipline. This standard provides additional information to an

AEO to develop a competency management system (CMS) that meets the minimum AEO

requirements, stated in T MU MD 00009 ST. It also provides guidance to the AEOs in the

assessment of personnel who are required to demonstrate competency within the signalling

discipline.

2. Purpose This standard aims at establishing the generic competency requirements of personnel who are

required to be recognised as competent to perform functions within the signalling discipline on

the TfNSW heavy rail network. This standard assists in the assessment and determination of

the competency of the signalling personnel in a consistent manner.

2.1. Scope This standard provides the competency requirements that can be incorporated into the AEO's

CMS and can be used for assessing the competency of the signalling personnel. It also

provides the context, drivers and definitions behind the standards that serve as a point of

reference for AEOs and other key stakeholders.

This standard is limited to generic competency requirements only and does not cover specific

domain or product knowledge elements which may be required by the AEO for network specific

licensing and authorisation; for example, domain and product requirements set out by the

relevant operator and maintainer or rail infrastructure manager (RIM).

This standard covers the requirements for the functions within the concept design phase,

detailed design phase and commissioning phase of the asset life cycle.

This standard does not cover other functions that exist in the asset life cycle.




2.2. Application This standard applies to AEOs who engage signalling personnel to perform work on the TfNSW

heavy rail network. This standard is intended to provide the AEOs with information on

function-specific minimum generic competency requirements.

5. Overview of competency standard This standard provides the competency requirements for personnel to develop and demonstrate

the competencies and proficiency levels required to undertake the specified signalling functions.

It also specifies the minimum generic competency tasks and evidence criteria, relevant to these

functions.

The functions that are selected and addressed within this standard primarily exist across the

infrastructure designing, and testing and commissioning areas of signalling systems.

The competency tasks and associated evidence criteria presented within this standard

encompass the competency requirements of functions within a role. The AEOs should

determine the applicability of each competency task, based on the scope of work being carried

out in the project and tailor the criteria accordingly. AEOs may choose to specify on a

commercial basis more than is documented within this standard.

The competency standards are provided for those functions where there is limited information

available to enable AEOs to develop reasonable assessment criteria. They are not intended to

cover the exhaustive list of functions that exist over the full asset life cycle.

Note: Reference has been made to the competency requirements of the Institution of

Railway Signal Engineers as an internationally recognised framework and extracted

the relevant elements, while adding specific local requirements.

The competency standard is subject to review at regular intervals as the industry needs

changes.

Section 5.1 through to Section 5.7 explains the different elements of the competency standard

such as the roles and functions, proficiency levels, and competency requirements.

Appendix A explains the process flow and guides the AEOs in applying this standard.




5.1. TfNSW competence, compliance and licensing The ASA has presented the competency standards which are generic and considered the

minimum requirements to work on the TfNSW heavy rail network.

The standards are independent of network specific domain or product knowledge requirements

that are required to perform the services or operate the network.

This is illustrated in Figure 1.


Figure 1 - Competency laws and regulations

5.2. Domain and product specific requirements The domain knowledge and product knowledge are specific to an application or industry area

and are gained from a combination of organisational standards, safety practices, locality, local

systems, infrastructure arrangements and principles, and local arrangements for work. This can

be independent or supplementary to generic knowledge.

Each RIM has developed processes and procedures for the management of the engineering

activities in their respective discipline area or area of operation (that is, domain). In many

instances, the processes were developed independently and over many years, often being

bespoke to the specific domain or discipline area. This has resulted in similar, but different,

approaches being used for the same area of activity from one domain or discipline to another.

To deliver particular engineering tasks, the AEO shall demonstrate competence to domain

specific requirements when undertaking an engineering task that affects any Transport asset.



The AEO shall ensure that the person undertaking the designing, testing and commissioning

engineer functions has demonstrated domain and product specific competence relating to the

specific RIM domain for which works are being carried out.

The AEO can demonstrate its capabilities in meeting the domain or product competence by

satisfying the following:

• evidence requirements specified in Section 6, Section 7, Section 8 and achieving the

identified domain knowledge and product knowledge; this can vary slightly within each

railway network

• licensed to the RIM specific authorisation standard (refer to the applicable RIM for

guidance)

5.3. Role and functions This standard covers a range of generic role functions, rather than referring to generic job titles;

that is, the functions that a jobholder is expected to perform. The function is a speciality area of

a role comprised of a collection of tasks.

Figure 2 illustrates how the functions are attached to a particular role.


Figure 2 - Functions within a role

Table 1 provides a list of high level functions and their description within any signalling roles.

Table 1 – Signalling functions and description

Function Description

Design The process of defining requirements or creating a solution or modifying the existing solution based on the identified requirements of that phase.

Check (review) A document based process of examination of the design to determine the adequacy of the output items of a specific development phase fulfils the requirements of that phase.

Verify A process of examination of the design followed by a judgement based on evidence that output items of a specific development phase fulfils the requirements of that phase in relation to completeness, correctness and consistency.

Approve A process based examination of the design to make sure all required steps have been completed in that phase in accordance with the approved quality requirements.



Function Description

Construct (install) The process of realisation of the design by building one or more products or set up the product to be functional as specified within the design phase.

The application of these functions to a particular job or role is explained in the following

examples:

• Example 1

A design engineer responsible for designing a part of a subsystem in the signalling

infrastructure requires competency for signalling detailed design.

• Example 2

An experienced signalling engineer responsible for verifying the detailed signalling design

for a signalling system requires competencies in detailed design, checking / reviewing and

verification.

• Example 3

A commissioning engineer responsible for deploying a major system into service requires

competencies for the testing and commissioning functions.

5.4. Signalling functions and asset life cycle The functions within the signalling systems cover the following:

• requirements specification (includes subsystem requirements)

• concept design

• preliminary design

• detailed design

• construction (build)

• factory acceptance subsystem testing

• site acceptance testing

• certification

• commissioning

• preventative

• corrective maintenance

• investigations




• technical strategy

• type approval

This standard covers the functions and the generic competency requirements within the concept

phase, design phase, and testing and commissioning phase of the TfNSW asset life cycle

model.

Figure 3 shows the alignment of the signalling functions within the TfNSW asset life cycle

model. The asset life cycle includes the following stages:

• demand/need

• plan

• acquire

• operate/maintain

• dispose


Figure 3 – Signalling system life cycle model

5.5. Defining prerequisite competence requirements The mandatory requirement for defining competence requirements is stated in

T MU MD 00009 ST AEO Authorisation Requirements.

The level and depth of the requirements depends on industry requirements or those required by

the standards.

An AEO's processes shall satisfy quality and safety requirements, as a minimum.



As part of the AEO authorisation process, AEOs shall have their own competency assessment

process as described in T MU MD 00009 ST.

The AEO may tailor the competency standard requirements to meet the project or industry

needs in consultation with the relevant stakeholders to align with the project requirements. Any

modification to the competency requirements stated in Section 6, Section 7 and Section 8 shall

be justified and be subject to audit. The ASA shall establish and maintain consistency among

AEOs’ assessments using the surveillance audit mechanism.

5.6. Proficiency levels The AEO’s competency management system shall define the proficiency levels that are relevant

and current for any particular function in accordance with the requirements of

T MU MD 00009 ST. While the AEO is responsible for setting a proficiency level framework, the

proficiency levels provided in Table 2 are suggested as most appropriate to be used with this

standard.

Table 2 – Proficiency levels and description

Proficiency Description

Level 0 A person who has had no previous experience of a particular task or activity. Requires supervision while performing tasks.

Level 1 A person who has limited knowledge. Requires supervision in more complex tasks and activities to allow that person to gain relevant experience. May perform simple tasks unsupervised where previous experience can be demonstrated.

Level 2 A person who has sufficient knowledge allowing to work unsupervised in tasks and activities within the relevant experience. May perform more complex tasks unsupervised where previous experience can be demonstrated. Requires supervision to perform more complex activities and tasks where previous experience cannot be demonstrated.

Level 3 A person who has demonstrated knowledge and experience, who can work unsupervised in tasks and activities within their relevant experience. May perform more complex tasks unsupervised where previous experience can be demonstrated. Has the relevant experience to execute the duties in a senior position as a leader and has the ability to solve problems. Can interpret and apply applicable domain standards and principles. Is considered to be a subject matter expert (SME) and has the capability and experience to supervise.




5.7. Competency requirements This standard establishes the signalling competency requirements for the personnel carrying

out the key signalling functions during the concept phase, design phase, and testing and

commissioning phase of the asset life cycle.

The competency requirements apply to the key functions that are broken down into tasks and

evidence criteria. The signalling personnel are assessed based on these tasks and the

evidence criteria that help to support and demonstrate the competency of a person.

The generic evidence and domain and product evidence should be mapped against each

evidence criteria of a given task.

The generic tasks within the signalling discipline that are identified in this standard are as

follows:

• application of principles

• general technical skills and experience

• railway operations

• interdisciplinary review (IDR)

• safety assurance

• product safety

• commission system into service

Table 3 lists some examples that explain the evidence criteria and provides appropriate

examples of evidence for a task.

Table 3 – Examples of tasks and evidence criteria


Task Evidence criteria Appropriate evidence examples

Application of signalling design principles

Understanding of general signalling principles including signal positioning, calculation of braking distances, headways requirements and signal sighting

• assessment of logbook and currency of entries; these will typically include work experience storyboards detailing particulars of work carried out, training records (academic or industry) and so on

• demonstrate academic record to include relevant industry training

• example deliverables, meeting minutes • design review comments registers • reports of corrective actions • reassessment engineer reports • approved signalling design

documentation



Task Evidence criteria Appropriate evidence examples

General technical skills and experience

• creates concept design deliverables

• reliability, availability, maintainability and safety (RAMS) analysis

• understanding of operators’ requirements

• evidence of meeting minutes • design review comments registers • reports of corrective actions • reassessment engineer reports

The order in which the tasks and the evidence criteria are presented is not intended to imply

relative importance to each other; however, it attempts to correspond to the logical sequence of

tasks performed across the asset life cycle model.

Different levels of responsibility and proficiency apply to each task, rising from designer up

through checker to verifier. While the evidence criteria described for each task can be the same,

the appropriate proficiency level for the role shall be considered.

AEOs shall seek scalable evidence that reflects the range and complexity of the work being

carried out to ensure that the signalling personnel has the required breadth of knowledge and

the experience and expertise to enable them to carry out the required function in a competent

manner.

6. Signalling concept design generic competencies The signalling concept design is the phase of project planning that includes producing ideas and

taking into account the pros and cons of implementing those ideas. This phase of a project is

done to minimise the likelihood of error, manage costs, assess options and risk, and evaluate

the potential success of the intended project.

The signalling personnel undertaking works on behalf of the AEO during the concept design

phase shall demonstrate sufficient competence and understanding of minimum requirements

detailed in T MU AM 04001 PL TfNSW Configuration Management Plan; however, the size and

complexity of the work being carried out should be considered.

Table 4 through to Table 9 describes the minimum generic competence requirements for the

signalling concept design phase. These tables also indicate when the applicable RIM is required

to seek further evidence of domain and product competency requirements and minimum

evidence requirements.

The information provided in Table 4 through to Table 9 can also be used as a guide or template

for the AEOs to gather evidence of assessment to satisfy the AEO's CMS and their claim for

competence to the applicable RIM for licensing.

The signalling personnel shall have the assessable ability to produce the following key

deliverables during the concept design phase:

• signalling arrangement plan or scheme plan © State of NSW through Transport for NSW of 39



• control tables

• signalling functional specification (SFS)

• input into the assurance process in accordance with applicable configuration management

process

Note: Depending on individual project requirements, these deliverables are not

necessarily required at the concept design phase.

8. Signalling commissioning generic competencies The signalling commissioning is the systematic process of ensuring that all equipment and

systems perform interactively according to the design intent and the operational and user

requirements.

The signalling personnel undertaking works on behalf of the AEO during the signalling

commissioning phase shall demonstrate sufficient competence and understanding of minimum

requirements detailed in T MU AM 04001 PL; however, the size and complexity of the work

being carried out should be considered.

Table 25 through to Table 30 describes the minimum generic competence requirements for the

signalling testing and commissioning phase. These tables also indicate when the applicable

RIM is required to seek further evidence of domain and product competency requirements and

minimum evidence requirements. © State of NSW through Transport for NSW of 39



The signalling personnel shall have the ability to produce the following key deliverables during

the testing and commissioning phase:

Appendix A Process flow for claiming competence

The process flow diagram depicts the steps to be followed to assess the competency of a

signalling person and obtain the authorisation to work from the RIM.

This process guides the AEOs in applying this standard through the different stages of

assessment and helps to achieve the following:

• identify the appropriate role and the relevant prerequisites / qualifications that a signalling

person should hold for the role they are being considered for

• identify if the signalling person is able to demonstrate compliance with the detailed generic

competency standards

The competency standards are expressed as a series of functional tasks and evidence criteria

and the objective evidence that the signalling person would be expected to present to support a

claim of competency in any area.

Figure 4 shows the process flow diagram for claiming competence and deploying a competent

person to discharge a particular function on the infrastructure.

Note: This is an indicative process that suits the existing situations of the current RIM

of the Sydney metropolitan area.




Step 7 - AEO claim for competence to RIM – assess candidate against evidence criteria based on defined suitable evidence

requirements & assess to levels of proficiency

Step 1 – Assess candidate’s broad role for functions expected

to perform

Step 2 – Identify lifecycle phases applicable to the role

Step 3 – Determine which functions apply (Sections 6-8)

Step 4 – Determine the level of proficiency required for each

element of the role (refer section 5.6)

Step 5 – Identify the evidence requirements for applicable

functions

Can candidate complete the claim for competence? YES

No

Step 6 – Undertake gap analysis between role requirements and

level of proficiency and the assessment results and address

RIM Reviews Application

Generic ProductDomain

RIM comment on application and any additional domain and product

attributes clarified.

Candidate deemed fully competent?

Yes

No

Skills gap analysis and training needs identified. Candidate can be reassessed again in the future. Revised or restricted

competency issued in interim.

Issue Certificate of Competency for assessed scope

RIM reviews Certificate of Competency and validates

RIM issues authorisation to work


Figure 4 – Process flow diagram

The following steps describe the process:

i. Assess the signalling person's broad role for the functions they are expected to perform.

Refer to Section 5.3 for more information on roles and functions.

ii. Identify the life cycle phases that are applicable to the role.

Refer to Figure 3 for the life cycle phases in the asset life cycle.

iii. Determine the functions that apply to the signalling person's role.

The tasks for each function are explained in Section 6, Section 7 and Section 8.

iv. Determine the level of proficiency required for each task of the role.

Refer to Section 5.6 for proficiency levels.

v. Identify the evidence requirements for applicable functions and determine if the signalling

person has sufficient evidence to complete the claim for competence.

vi. If the signalling person does not have sufficient evidence then undertake a gap analysis

between role requirements and level of proficiency and the assessment results.



Address the gaps to then complete the claim for competence.

Or

If the signalling person has sufficient evidence then the AEO claims for competence to the

RIM to assess the signalling person against the criteria-based evidence across generic,

product, domain requirements and assess to levels of proficiency.

vii. RIM reviews application to determine if any additional domain and product attributes need

clarification and determine if the signalling person is deemed fully competent.

viii. If the signalling person is not deemed competent, identify the skills gap analysis and

training needs.

The signalling person can be reassessed in the future. A revised or restricted competency

certification can be issued in the interim.

Or

If the signalling person is deemed competent, then the Certificate of Competency is issued

for assessed scope of work.

ix. The RIM reviews and validates the Certificate of Competency and issues the authorisation

to work.
