New requirements for the interoperability of railway operations have been agreed by Australia’s Infrastructure and Transport Ministers and take full effect on 28 February 2026.
To support rail transport operators to comply with the changes, ONRSR has developed a guideline in collaboration with the National Transport Commission (NTC) and Rail Industry and Safety Standards Board (RISSB).
Consultation on the guideline is open until 14 November 2025. Find out more below.
The NTC consulted with industry in late 2024 on a regulation that requires operators on the National Network for Interoperability (NNI) to consider interoperability when making changes to their operations. For any changes that will impact interoperability, operators will be required to prepare an Interoperability Management Plan (IMP) as part of their safety management system.
The nation’s Infrastructure and Transport Ministers recently approved the regulation and officially the change will be made on 1 November 2025 and, after a transition period, operators will be required to comply from 28 February 2026.
Interoperability in the Australian rail industry refers to the ability of different rail systems, technologies, rules and operators to work together safely, seamlessly and efficiently across the NNI.
Historically, Australia’s railways developed in isolation across states, resulting in inconsistent standards, signalling systems, communications and operational rules.
Improving interoperability and establishing the NNI reduces safety risk from system complexity and increases freight and passenger productivity. It also supports the adoption of modern digital rail technologies and national harmonisation initiatives led by ONRSR, the NTC and industry stakeholders. In practical terms, interoperability enables a more connected, efficient and future-ready rail system for Australia.

The new requirements will only apply to accredited rail infrastructure managers that are part of the NNI and accredited rolling stock operators that have accreditation to operate on the NNI. Operators that are determined by the Regulator to be a tourist and heritage operator will be exempt from the new requirements.
The Draft Guideline - Interoperability of Railway Operations is designed to support operators with implementation of the requirements.
Interested parties can provide feedback on the draft guideline until 14 November 2025 by emailing contact@onrsr.com.au
