Building resilience today secures Australia’s freight rail network for the long haul

By Ilan Sagi, Director, Transport Clients & Growth, KBR

Australia’s freight rail network is the backbone of our economy, providing just-in-time essential products, moving bulk commodities, and connecting supply chains across vast distances. But as customer expectations increase, climate pressures intensify and freight demand surges, resilience has become a critical priority. Recent floods, bushfires, and cyclones have exposed vulnerabilities in key freight corridors, disrupting major supply chains and costing hundreds of millions in lost productivity.

According to the National Freight Data Hub, domestic freight volumes are forecast to grow by 26% between 2020 and 2050 with 6% of that growth in rail freight alone. The challenge is clear – we need modern and reliable rail networks that can withstand extreme weather and rising capacity demands.

The challenges operators face

Australian operators are navigating through a mix of critical risks and challenges. Climate volatility and extreme weather events pose ongoing threats, with flooding and heatwaves repeatedly impacting train services and exposing the fragility of our aging infrastructure. These disruptions ripple across supply chains, leaving communities without supplies, and undermining confidence in rail as a reliable freight mode.

At the same time, demand for intermodal and bulk freight is rising sharply, straining networks that lack redundancy and appropriate resilience standards. Trying to address these challenges, rail infrastructure managers and operators also contend with the true complexity of integrating digital signalling, automation, and predictive maintenance into systems originally designed for a different era. The result is a rail network that is still vulnerable to both physical and technological disruptions, where every failure carries economic and reputational risk.

What needs to be done

To build resilience into Australia’s freight rail network, we need a coordinated and strategic approach. First, we must acknowledge the critical role rail plays in our supply chain and society, ensuring its importance is reflected in planning and policy decisions. This includes lobbying for greater government investment in resilience and moving beyond the current ‘user-pay’ funding model that limits long-term and step-change improvements.

Rail infrastructure managers must develop a deep understanding of their networks and proactively address both current and future vulnerabilities. Comprehensive hydrological assessments, such as those recently undertaken by ARTC, are essential to fully grasp the potential impacts of extreme weather and climate change on key corridors. Similarly, live temperature mapping can help identify extreme heat induced track buckling and extreme cold induced rail breaks, enabling preventative measures to be implemented in track sections most at risk.

Strategic investment in resilience and redundancy is equally important, with measures such as major culvert upgrades, improved capacity and alternative pathways to limit impact and maintain continuity during disruptions.

Adoption of advanced monitoring systems and live data capabilities which can detect risks early and enable proactive maintenance and response is also key. This means embracing technologies such as predictive maintenance, AI-driven asset management, and automation to optimise performance and extend asset life. Finally, robust contingency planning is critical to minimise supply chain impacts and keep essential goods moving when extreme events do occur.

Looking ahead

The refreshed National Freight and Supply Chain Strategy identifies resilience as a core priority alongside productivity and decarbonisation. The Australasian Railway Association (ARA) is leading the charge, developing an industry-first Resilience Framework to provide a nationally consistent approach to managing climate risks and operational disruptions. Industry bodies like Roads Australia echo this call, advocating for coordinated investment and a unified approach to resilience across the transport sector.

With billions in investment earmarked for Australia’s rail upgrades over the next decade, there has never been a better time to build resilience into Australia’s freight rail network. And projects such as Inland Rail and ARTC’s Network Investment Program (NIP) show what’s possible when resilience is embedded from the outset, designing networks that anticipate climate extremes and operational pressures. Future-proofing Australia’s freight rail network will require collaboration between government, industry, network operators and users. After all, resilience is not just about hardening assets; it’s about creating adaptive systems that recover quickly and thrive under pressure, safeguarding supply chains and economic stability. By making the right decisions today, we can help to build a thriving, resilient and sustainable freight rail network for years to come.
