ARA National Matrix Update

The National Rail Industry Worker Matrix Committee (NRIWMC) and its Matrix Working Group have been working on standardising new national matrices.

National roles assist contractors working for multiple Employers, Operators or across multiple Networks as roles are recognised and accepted nationally. 

The aim of standardising roles is to provide consistency and agreed minimum requirements at a national level. The roles are reviewed and agreed upon by subject matter experts who join the working group from across industry.

There are currently four 
National Matrices live in the RIW System:
National Matrix Update

Recently, the National Rail Industry Worker Matrix Committee (NRIWMC) and its Matrix Working Group have been working on releasing new national matrices. The next four national matrices to be released are the following:
  • National Power & Electrical Matrix – released, 8 May 2023
  • National Signalling Matrix – to be released, TBC
  • National Engineering Matrix – to be released, TBC
  • National Project Management Matrix – to be released, TBC

The new roles and matrices will be prioritised and released based on industry demand.
This means that contractors who work for multiple Network Operators, Rail Infrastructure Managers or Rolling Stock Operators will no longer need to undergo repeat training and will gain instant recognition for their qualifications and health obligations via the Rail Industry Worker Program across states.

By agreeing on minimum requirements and ensuring consistency across states, this initiative will provide many benefits to industry.

The new National Power & Electrical Matrix will be the first matrix to be released. It will include the following 4 national roles in the initial release:
  • Traction Overhead Lineworker – National (In-training)
  • Traction Overhead Lineworker – National
  • Distribution Overhead Lineworker – National (In-training)
  • Distribution Overhead Lineworker – National
The next area of focus will be substation roles which will be included in the second National Power & Electrical Matrix release. These roles are still under development. Communication to industry will be issued once they go live.

What does this mean for me?

Cardholders / Employer Administrators
1. If you or your employee already hold a Network version of the Lineworker Traction or Distribution Overhead Role(s) for one or more networks:
I. You will need to add one of the above equivalent National Role(s) to your RIW card.
II. You may need to obtain new competencies or complete other requirements. Please check with your employer administrator if this is the case. (Please note, once the new role has been added to a cardholders profile the system will identify what competencies are missing from the job role)
​​III. Any existing certified competencies that are an exact match from your network role will automatically transfer when you have added the new National Role.
​2. Keep an eye out on Network Operator communication, as the relevant Network Operator will communicate to industry when they will mandate the national equivalent Lineworker Roles and any additional required actions.  

Network Operators, Rail Infrastructure Managers and Rolling Stock Operators
1. If your organisation already has a relevant Network Role(s) for Lineworker:
I. You will need to alter the Business Rules in RIW as some requirements will move from your existing Network Role to the new National Role.
II. You will need to review your requirements to determine if a domain specific Lineworker role is required to capture any local requirements.
III. You will need to communicate a date to relevant employees and contractors for when the new role requirements for your network come into effect.
IV. You can begin adding the new National Roles to your employees RIW cards.

Next Steps for the National Rail Industry Worker Matrix Committee (NRIWMC) and its Matrix Working Group:

Based on industry needs, in no particular order, the following activities are planned:
  • Release the second version of the National Power & Electrical Matrix to include the Substation roles.
  • Finalise the National Signalling Matrix, Engineering Matrix & Project Management Matrix and communicate release dates to industry.
  • Begin consultation with Subject Matter Experts (SMEs) and develop the next 4 national matrices for industry benefit:
    • National Train Driver Matrix
    • National Track Protection Matrix
    • National Rollingstock Maintenance Matrix
    • National Telecommunications Matrix
