What are the RIW Matrices and how were they developed?

An RIW Matrix is a table that is used to clearly demonstrate the competencies required to hold a particular role to work in the rail industry. 

The RIW Matrices can be found on the RIW website at https://www.riw.net.au/business-rules/network-operators/ 

The National Rail Industry Worker Governance Committee (NRIWGC) is continually working to standardise roles across the rail industry nationally.

In September 2018, the NRIWGC revised the National Matrices which outline the competencies required to hold specific roles. These updates were to improve and simplify the selection of roles and provide improved descriptions for users. In most cases the competency requirements for these roles have been rationalised.


The revised matrices provide further consistency and agreed minimum requirements across participating rail operators and will assist contractors working for multiple employers, operators or across multiple networks. There have been limited changes made to the competencies and roles within the previous matrix. The most significant change to be aware of is the new structure – the matrix has now been simplified and split out into four matrices. 

The following National Matrices are applicable to the RIW Program:

  • National Track and Civil Matrix
  • National Plant Matrix
  • National Trades Matrix
  • National Operator Roles Matrix

The requirements as outlined in these matrices have been agreed by the following rail operators in the NRIWGC:

  • Australian Rail Track Corporation (ARTC)
  • Department of Planning Transport and Infrastructure (DPTI)
  • John Holland Group (Country Regional Network – CRN)
  • Metro Trains Melbourne (MTM)
  • Queensland Rail (QR)
  • Transport for NSW
  • V/Line


NOTE: Meeting the requirements for roles within the National Matrices does not automatically allow a cardholder access to the various Networks. It is important to check with the operator to determine the application of the National Matrices to the Network and if there are any other requirements a cardholder needs to meet before they can work on track.

Note: Some Network Operators do have additional matrices for working on their Network. Please refer to https://www.riw.net.au/business-rules/network-operators/ or check with the relevant Network Operator
