Is Rio Tinto’s A$150m Karratha move the start of mining infrastructure reshoring in Australia?

How Rio Tinto’s Karratha rail car project could reshape Australian regional manufacturing in 2025

Rio Tinto has officially launched the first iron ore rail car manufactured in Karratha, Western Australia, marking a major milestone in its A$150 million strategic partnership with Gemco Rail to strengthen local industrial capacity. This rail car is the first of its kind to be built in the Pilbara, part of a broader initiative to construct 100 iron ore rail cars in Western Australia and move key manufacturing operations closer to the heart of Rio Tinto’s mining activity.

The new rail car was completed at a purpose-built Gemco Rail facility in Karratha, following the earlier delivery of 40 Western Australia-made cars at Gemco’s Perth operations. The remaining 59 units of the contract are set to be assembled in Karratha using relocated machinery and tools from the Perth site. These rail cars will be deployed to haul iron ore from Rio Tinto’s 18 Pilbara mining operations to its coastal ports at Dampier and Cape Lambert, beginning later this month.

Each of these new cars is capable of transporting up to 118 tonnes of ore and will help support Rio Tinto’s logistics network, which spans nearly 2,000 kilometres of track and moves more than 300 million tonnes of iron ore annually. With a fleet of approximately 13,500 ore cars and an average replacement rate of 10 units per year, the miner’s shift to local manufacturing reflects both a strategic supply chain realignment and an effort to reinforce regional industrial ecosystems.

Why Rio Tinto is reshoring rail car manufacturing to the Pilbara

The decision to bring rail car production into the Pilbara reflects a wider shift in how mining companies approach supply chain risk, regional resilience and community engagement. Rio Tinto’s move to produce rail cars in Karratha marks a rare reshoring initiative in the Australian mining sector, one that analysts believe could signal broader changes in procurement patterns across heavy industry.

Matthew Holcz, Chief Executive of Rio Tinto Iron Ore, stated that local manufacturing has tangible benefits for the company’s operations and for the communities in which it works. He highlighted that relocating this capability to the Pilbara not only creates local jobs and boosts economic activity but also enhances supply chain security for mission-critical rolling stock components.

According to Holcz, Rio Tinto’s logistics challenge is not just about moving tonnes of ore efficiently, but doing so with an agile and maintainable fleet that can be supported in close proximity to mine sites. The company’s Pilbara rail operation is among the largest privately owned heavy-haul rail systems in the world. Bringing manufacturing into the region is expected to cut down on transit delays, improve spare part availability and reduce long-term maintenance costs.

The new Karratha workshop is also expected to support bearing refurbishment activities and serve as a platform for additional rail engineering functions in the future. Up to 25 local jobs are being created in the first phase, with potential expansion based on production needs and broader supply chain integration.

How Gemco Rail is building rail car capabilities in Karratha

Gemco Rail, a subsidiary of Engenco Limited, is leading the Karratha manufacturing operation and has made significant infrastructure investments to support the program. The company relocated key assembly equipment and machinery from its existing Perth-based operations to the new Pilbara facility, ensuring continuity in quality and production capacity.

Dean Draper, Chief Executive Officer of Engenco Limited, said the Karratha expansion enhances the company’s ability to work closely with mining clients, reduce logistics lead times and build a local talent pipeline in heavy rail fabrication and maintenance. Draper described the project as a proof point in Australia’s ability to reindustrialise its remote regions through public-private collaboration and long-term offtake commitments.

The Karratha site is being positioned not only as a production base but also as a regional service hub capable of scaling its activities in step with demand from Rio Tinto and potentially other resource companies in the future. Draper noted that the ability to respond quickly to customer needs, manage component life cycles and ensure high-quality outcomes is made easier when manufacturing is integrated locally.

What the Western Australian Government hopes to achieve from this partnership

The Western Australian Government has been a vocal backer of reshoring manufacturing capacity in both metropolitan and regional areas. Premier Roger Cook described the milestone as part of a broader industrial strategy to transform Western Australia from a raw material exporter into a globally competitive advanced manufacturing jurisdiction.

He noted that Western Australia has already brought railcar manufacturing back to Perth for public transport vehicles and now, with Rio Tinto and Gemco Rail’s effort in Karratha, is making inroads into the high-capacity resource logistics sector. According to Cook, these local production capabilities are key to economic diversification, regional job creation and long-term industrial resilience.

The state’s support for the initiative was framed as a way to unlock regional development and encourage more large corporations to follow Rio Tinto’s example in partnering with local suppliers and reinvesting in regional infrastructure. Cook emphasised that such partnerships are vital to building a future where Western Australia “makes more things here,” even in remote locations like the Pilbara.

How does CRRC Qiqihar’s engineering support strengthen Rio Tinto’s push to localise rail car manufacturing in the Pilbara?

The Karratha rail car rollout was made possible through a three-way partnership formed in 2023 between Rio Tinto, Gemco Rail and Chinese rolling stock manufacturer CRRC Qiqihar Rolling Stock Co. Ltd. While the manufacturing has now been partially localised, CRRC Qiqihar continues to provide engineering support and supply chain coordination to ensure that the locally produced cars meet global quality and performance benchmarks.

Vincent Zhu, a representative from CRRC Qiqihar, stated that the company is proud to support Rio Tinto’s localisation efforts in Karratha and remains committed to delivering value through technical collaboration. Zhu said the project demonstrates the ability of global partners to adapt their support models to align with regional development goals.

By combining local manufacturing with international design and engineering expertise, the partnership seeks to create a sustainable ore car production ecosystem that can adapt to future technological and logistical challenges while reinforcing Western Australia’s manufacturing credibility.

What this means for Western Australian suppliers and Rio Tinto’s local spending

The Karratha initiative is part of a broader strategy by Rio Tinto to embed itself more deeply within the Western Australian economy. In 2024, the miner disclosed that it had spent a record A$10.3 billion with Western Australia-based suppliers, spanning categories from engineering services and maintenance to equipment, energy and construction.

This level of local procurement reflects a deliberate strategic shift toward regional engagement, particularly as resource companies face increasing scrutiny over their social licence to operate, local hiring practices and environmental footprint. It also signals the growing economic interdependence between major extractive companies and the communities in which they operate.

Analysts tracking mining procurement trends say Rio Tinto’s local-first approach could accelerate interest from other miners looking to de-risk their supply chains, especially for high-usage components like rolling stock, tyres, conveyor belts and autonomous vehicle modules. They see Pilbara-based manufacturing as a test case for broader reshoring in Australian mining and energy infrastructure.

Could this rail car project trigger a new wave of mining infrastructure reshoring?

Industry observers believe that Rio Tinto’s commitment to building ore cars in Karratha could mark a turning point in the localisation of mining support infrastructure. While cost pressures and labour availability remain ongoing concerns, the success of the current program may encourage other resource players to consider similar moves for different asset classes such as truck chassis, mobile equipment, bulk handling systems or even critical technology components.

From a policy and investment perspective, regional manufacturing hubs like the Karratha facility could also serve as anchor points for broader economic clusters involving vocational training, component manufacturing, and services provision. For local businesses, it opens up a long-tail opportunity to integrate into mining value chains that were previously inaccessible due to geographic and logistical constraints.

The pilot’s success will depend not just on unit economics but also on the long-term collaboration between government, industry, and suppliers. If scalable, Rio Tinto’s Karratha rail car program could become a leading case study in how remote manufacturing can thrive in Australia when backed by capital-intensive industries.
