The National Transport Commission shares why investing in interoperability will play a key role in enabling Australia to move more freight on rail.
Lifting capacity across Australia’s rail networks is critical if the sector is to take on a bigger share of the country’s growing freight task. This requires greater efficiency and improved connectivity, so trains can move more easily across the networks that link cities, regions, ports and supply chains.
The independent body Infrastructure Australia (IA) has identified the interoperability of digital signalling and train control systems as a top infrastructure investment priority, reflecting its importance to Australia’s rail system and economy.
The National Transport Commission (NTC) has been working with the rail industry and governments to help meet this objective through the National Rail Action Plan (NRAP). The NRAP provides a coordinated approach to addressing long-standing challenges in Australia’s rail system by reducing differences and aligning systems and practices across networks. A key element of the plan is coordinating the deployment of digital train control systems on major interstate freight and passenger corridors, collectively known as the National Network for Interoperability (NNI).
“The national interoperability of digital signalling and train control proposal will support a safer, more reliable and productive rail system while improving supply chain efficiency and capacity,” said David Tucker, IA’s Chief of Project Advisory and Evaluation. “It will encourage more freight to move from road to rail, reducing emissions and easing pressure on road networks.”
NTC Chief Executive Officer Michael Hopkins said interoperable digital signalling technologies will strengthen the resilience of Australia’s freight networks, improving their ability to respond to shocks such as the current oil crisis.
“Getting agreement from Australia’s infrastructure and transport ministers on a single digital train control standard – the ETCS (European Train Control System) – for the NNI marked an historic step,” he noted. “However, there is still much to be done.”
Learning from Europe’s experience
European experience shows there is a risk that as the new ETCS technology is deployed, individual networks will adapt the system to suit local requirements, Hopkins said.
“If this occurs, we risk creating even greater barriers to interoperability and lower safety and productivity outcomes,” he added.
To avoid this, the NTC has been working with the Australian Rail Track Corporation (ARTC), governments and industry to plan for a consistent and cost-efficient rollout of ETCS across Australia’s diverse railways – from busy urban centres to remote outback corridors which currently have no signalling systems and, in some locations, no electricity.
The NTC plays a coordinating role in trackside and rolling stock strategies and facilitates a cost-sharing approach. Meanwhile, the ARTC leads planning for an ETCS solution, with a particular focus on the non-urban freight environment. This takes a whole-of-system view, including track infrastructure, rolling stock, network control and system integration.
“The focus is on identifying a scalable approach, balancing safety, performance and cost, while maintaining commercial viability over the short, medium and long term,” said Adrian Teaha, the ARTC’s Chief Interoperability and Development Officer.
“This includes progressing a national scoping business case to determine how digital systems can be introduced in a commercially sustainable way, maximising value for freight and passenger services while maintaining connectivity with key urban interfaces.”
The work is being undertaken in partnership with the Commonwealth and state jurisdictions, above and below rail operators and in significant consultation with technology suppliers and the broader freight industry, including unions.
“It’s a long-term transformation, requiring a phased pathway that recognises existing systems and constraints, incorporates interim solutions and allows for the adoption of emerging technologies over time,” Teaha said.
Why collaboration is important
While interoperability is critical if rail’s freight task is to grow and remain competitive, it cannot be addressed by any single organisation, Teaha said.
“NRAP is an important mechanism for bringing governments and industry together around the shared challenge of improving the efficiency and effectiveness of Australia’s railways.
“This extends beyond the rail corridor, ensuring that the movement of goods and people aligns with the national interest and remains cost-effective.
“NRAP provides a framework to support that alignment, helping to establish common priorities, guiding principles and a more coordinated path forward.”
Industry leaders such as Caroline Wilkie, Chief Executive Officer of the Australasian Railway Association (ARA), agree that taking a national approach to address interoperability is critical.
“A lack of interoperability across Australia’s rail networks is the single biggest drain on the industry’s productivity,” said Wilkie.
” National Cabinet’s identification of this issue as a priority gives us a once-in-a-generation opportunity to take action and supercharge our industry.
“The ARA has worked closely with the NTC on initiatives to improve interoperability under NRAP, and we look forward to continuing this focus as we enter a new phase of national rail reforms.”
With national alignment and sustained investment, the sector is well-positioned to play a much larger role in meeting Australia’s freight needs.
In an era of rising freight demand and high fuel costs, the advantages of rail are becoming increasingly clear.
The challenge now is to modernise and integrate the network to realise that opportunity.
