Last year, we consulted with industry on the requirement to have an Interoperability Management Plan for operations on the National Network for Interoperability (NNI).
Your feedback outlined the importance of a concise, clear and easily understood definition of the NNI, which needs to be gazetted prior to the requirement coming into effect. We also heard that the Hunter Valley Rail Network should be included within the NNI due to its strategic importance to the nation’s freight network.
We sought feedback on the updated NNI map and associated definition, found in this consultation paper.
Background - creating an interoperable rail system
Australia’s rail system is made up of 18 separate rail networks, 11 different signalling systems, and countless different rules.
With $155 Billion being spent modernising our rail networks and introducing digital train control systems, now is the time to ensure we have technologies that work together, more common operating rules and a simpler way to get trains on tracks.
Creating an interoperable rail system is a priority for all Australian governments.
Right now, under the Rail Safety National Law (RSNL) rail transport operators do not need to consider the national interoperability impacts of their individual network decisions.
A lack of interoperability across rail networks is a challenge to creating a safer and more efficient railway system.

Interoperability Management Plan (IMP)
To improve interoperability, the NTC has developed a new regulatory requirement in the RSNL National Regulations.
From 1 November, rail transport operators on the National Network for Interoperability (NNI) will need to have systems and processes that identify and consider interoperability matters. These must be applied when making changes to operations on the NNI.
If interoperability matters are identified, an Interoperability Management Plan will be required.
The new requirements will be phased in over a transition period, taking full effect on 28 February 2026.
The Office of the National Rail Safety Regulator (ONRSR) has released a Draft Interoperability of Railway Operations Guideline to help operators comply with these changes.
If you have feedback or questions about the guideline, email ONRSR at contact@onrsr.com.au
