Infrastructure and transport ministers have brought Australia’s major interstate rail corridors under one digital signalling technology standard. It’s an historic step to drive a more productive, safer, and sustainable national rail system.
Rail interoperability has been a long-standing challenge in Australia, with different gauges, digital systems and regulatory frameworks creating inefficiencies across the country’s 18 freight and passenger networks.
In what has been described as the biggest change to rail since electrification, infrastructure and transport ministers have set a national direction to address this fragmentation – setting a national digital signalling pathway, strengthening rail governance, and streamlining rolling stock approvals to improve productivity and safety and reduce transport emissions, while helping to move more freight and people around the country.
Getting alignment across networks is a National Cabinet priority, and ministers have now agreed to one digital signalling technology standard across major connected freight and passenger corridors, known as the National Network for Interoperability (NNI).
It means that all digital signalling introduced on the NNI in future must meet mandatory ETCS (European Train Control System) standards so trains fitted with ETCS technology can move seamlessly across rail lines connecting Australia’s busiest cities, regions and ports.
“We wanted to avoid each Australian rail network adopting its own system and creating a new digital break-of-gauge between networks,” says Catherine King, Minister for Infrastructure, Transport, Regional Development and Local Government.
“To truly unlock the potential of rail, we are committed to improving harmonisation and interoperability across the sector. This means streamlining regulations and standards nationwide.”
National Transport Commission Chair Carolyn Walsh likened the decision to the announcement last century to have a standard rail gauge across the country.
“It really is monumental for the future of rail in Australia in that it will improve efficiency, reduce costs and, importantly, improve the safety of railways,” Walsh says.
The changes have been welcomed by states and industry, with New South Wales Secretary of Transport Josh Murray noting it was hard to overstate the significance of states, territories and the Commonwealth all agreeing to pursue a common digital operating system.
“It’s the modern-day equivalent of finally choosing between VHS and Betamax, but for all the nation’s passenger and freight train control systems,” Murray says.
“The ideal is that freight trains will be able to move from the ARTC network to the network of another operator and utilise a consistent signalling system,” says King, adding that ministers had also strengthened the role of the Rail Industry Safety and Standards Board (RISSB) to ensure Australia had consistent, industry-led rail standards.
Australasian Railway Association (ARA) Chief Executive Officer Caroline Wilkie says the move will end decades of incompatibility and deliver “meaningful progress” toward a safer and more productive national rail system.
It will help to improve reliability and transit times, increase local manufacturing opportunities and help to reduce emissions through better fuel efficiency.
Rolling out ETCS
With the pathway now set, attention turns to implementation as the Australian Rail Track Corporation (ARTC) works closely with the NTC to roll out ETCS across the NNI.
The ARTC will lead the development of ETCS for non-urban environments, coordinating with other below-rail operators, customers, governments, and suppliers. While the NTC works with industry to develop a national rollout strategy, identifying the best order and timeline to fit ETCS technologies onto trains and tracks, as well as a cost-sharing framework to support future investment strategies, Infrastructure Australia has also identified the rollout of aligned national signalling on its national priority list.
“Digital signalling systems will give us powerful new insights,” Walsh says. “They’ll allow us to monitor trains’ performance, improve maintenance efficiency, and increase safety across the networks.”
Importantly, ETCS provides a shared digital language that allows data to flow seamlessly between networks. This creates opportunities to cut costs, boost productivity, and improve workforce mobility.
“Workers won’t need to retrain every time they move to a new network,” Walsh explains. “That’s a game-changer for both skills development and career pathways.”
Establishing a stronger national standards body
Alongside its decision on a national digital signalling platform, ministers endorsed a new, strengthened rail governance model with a bigger role for the Rail Industry Safety and Standards Board (RISSB) to advance national standards and deliver greater consistency across rail technology, trains, infrastructure, skills and training.
The model aims to overcome 20 years of low adoption of national standards by establishing a strengthened national standards body with teeth.
When making the decision, ministers considered three new governance options: expanding the role of the national regulator, creating a new statutory body, or strengthening RISSB. They rejected the first two as either conflicting or costly, instead tasking RISSB with taking on a bigger role as the industry-led standards body.
“Ministers agreed that the best way of continuing national reforms in a co-regulatory environment was for industry-led organisations to be involved in developing national standards with stronger alignment to national priorities,” says NTC Chief Executive Officer, Michael Hopkins.
“This will be a significant shift from Australia’s long-standing voluntary approach to standards to a more strategic and coordinated national approach that binds public and private rail operators together.”
The changes also require a more proactive role for the Office of the National Rail Safety Regulator (ONRSR) around interoperability. This will be explored as part of the consultation regulatory impact assessment for Rail Safety National Law reforms, already approved by ministers and out for public engagement in early 2026.
RISSB Chair Gillian Miles says the new RISSB will be led by industry, bringing public and private operators and suppliers to the table, with unions and governments to harmonise rail standards and implement the national rail standards.
RISSB Chief Executive Officer Alan Fedda says the organisation has already begun redesigning its standards development process, backed by stronger technical expertise and governance.
The changes will see RISSB lead the development of harmonised standards to support interoperability while the NTC continues to coordinate the development of rail’s first mandatory standards for ministerial approval. The first three mandatory standards will cover digital train control, driver interface, and rolling stock approvals.
Standards reform is based around a three-tiered framework with a must do/ should do/ can do logic.
“This unified approach will form the backbone of Australia’s future rail system,” says Hopkins.
A national pathway for rolling stock approvals
Another key reform agreed by ministers was a new national pathway for rolling stock approvals, as well as a coordinated national procurement strategy for passenger trains to boost local industry participation, grow Australia’s manufacturing capability, and build greater resilience across the rail supply chain.
Today, rail operators must navigate separate and often inconsistent approval processes in every jurisdiction they operate in. It’s costly and duplicative and means that in some cases it takes longer to get a new train approved than to build it.
The NTC and various states and rail infrastructure managers have been working on ways to remove complexities and reduce differences between network requirements.
The national pathway endorsed by ministers was developed by Transport for NSW in partnership with the NTC to consolidate and coordinate all rolling stock approval reform into one plan. It ensures all initiatives are pushing towards the same long-term vision of reducing the cost of rolling stock approvals for both rail operators and infrastructure managers.
The pathway includes work that the NTC is doing with governments and industry to:
- develop safety assurance guidance
- develop and pilot a single application form
- harmonise testing arrangements.
As well as jurisdiction-related projects, including harmonised interface standards, the New South Wales network acceptance process, and RISSB’s rolling stock register and registration system.
It’s a huge job, and the intent of the national pathway is to progressively build towards the national vision, starting with a pilot involving a small group of rail infrastructure managers and scaling up, says Hopkins.
New interoperability regulations help drive national rail reform
Further steps towards a more seamless rail system were taken recently with amendments to Rail Safety National Law regulations requiring rail transport operators on the NNI to have an Interoperability Management Plan as part of their Safety Management System.
The Plan will require rail infrastructure managers and rail operators to show they have considered national interoperability before making changes to their network. This marks a significant shift from the current approach, where networks need only focus on what works best for their own operations.
The amendment was made after extensive industry consultation and will come into effect from 1 November 2025 with a transition period until 28 February 2026.
“Right now, there’s such strong support for getting rail reform achieved,” says Walsh.
“This is about making rail a more competitive transport option. It’s about reducing emissions, improving safety, and helping move more people and freight efficiently as our population grows.”
