Five Bowen Basin mines.
One long-term rail agreement.
Aurizon has secured a new long-term, performance-based coal haulage agreement with BHP Mitsubishi Alliance, covering five of BMA’s major metallurgical coal operations across Queensland’s Bowen Basin.
The agreement can accommodate annual volumes of up to 37 million tonnes, begins on 1 July 2028 and can run for up to 12 years.
There is no reliable publicly disclosed contract value — and the commercial story does not need one.
The scale sits in the physical supply chain: mines, locomotives, wagons, workshops, rail infrastructure and export interfaces operating together for potentially more than a decade.
What Aurizon has actually secured
The new agreement is a long-term, performance-based rail haulage contract between Aurizon and BMA.
It becomes effective on 1 July 2028 and will replace the existing BMA agreement signed in 2015.
Annual volume-flexibility provisions allow haulage of up to 37 million tonnes per annum.
The contract can run for up to 12 years, subject to its performance and extension provisions.
At its maximum term, that would take the relationship through to 2040.
The agreement reaches across five major BMA operations
Collectively, those operations span some of the Bowen Basin’s most established metallurgical-coal mining districts.
Their output does not simply leave a mine gate.
It moves through a chain of loading infrastructure, heavy-haul rail operations, network paths and export-terminal interfaces before reaching international customers.
Reliability has to work from mine loadout to export terminal
A disruption at any one of those interfaces can affect the rest of the supply chain.
That is why a performance-based haulage agreement is not simply about locomotives completing kilometres.
It is about consistently moving coal through an interconnected mine-to-port system.
The contract connects production reliability with export reliability
Long-term haulage gives both miner and rail operator a stronger planning horizon around fleet, train paths, crews and asset availability.
The eventual task remains simple to describe but difficult to execute consistently: move metallurgical coal from multiple mines through a heavily utilised rail system and into export terminals on schedule.
What sustained haulage means beyond the locomotive cab
Rail haulage at this scale depends on a broad operating ecosystem.
Select a part of the system below to see where the supporting work sits.
Long-term volumes support continuing demand for fleet inspections, planned maintenance, wheel and brake work, components, condition monitoring, cleaning, reliability engineering and operational servicing.
Track, turnouts, signalling, communications, train control, electrical systems and network-maintenance windows all affect the ability to move contracted coal volumes consistently.
Fleet availability depends on workshops, maintenance labour, spare parts, machining, fabrication, specialist equipment, inspections and planned overhauls throughout the contract period.
Mine production, train scheduling, network paths and terminal receival all need to work together. The real performance metric is not simply train movement — it is reliable movement through the complete export chain.
Every tonne hauled creates an asset-reliability obligation
Long-term rail contracts give maintenance planning a much longer horizon than spot or short-duration haulage.
Locomotives and wagons accumulate operating hours and kilometres. Workshops have to absorb scheduled maintenance. Components wear. Wheels, brakes and running gear need attention.
Reliability therefore becomes a recurring industrial-services story throughout the term of the agreement.
Where long-term haulage creates recurring industrial demand
The physical numbers matter more than an invented contract value
Those numbers explain why the contract matters without assigning a speculative dollar figure.
At the upper annual volume, a large quantity of metallurgical coal must repeatedly move through the same fleet, workshops, rail corridors and export interfaces.
Asset availability therefore becomes a long-term commercial requirement rather than a short-term logistics exercise.
The agreement sits inside Australia’s largest export coal rail network
Aurizon Network operates and manages the Central Queensland Coal Network, a 2,670km multi-user rail network serving the Bowen Basin.
The CQCN comprises the Newlands, Goonyella, Blackwater and Moura systems together with the Goonyella Abbot Point connecting system.
Aurizon says the network connects more than 50 mines with five major export terminals as well as domestic customers.
That wider network scale matters because BMA trains operate inside a system shared with numerous mines, rail operators and terminal supply chains.
Contract performance therefore depends not only on individual train assets, but also on how well capacity, maintenance and disruption are managed across the wider network.
The commercial story is sustained utilisation, not a headline contract value
There is no need to manufacture a billion-dollar number to make this agreement significant.
Aurizon has secured a rail task covering five major Bowen Basin metallurgical coal operations, annual volume flexibility of up to 37Mt and a potential contract horizon extending to 2040.
That is physical scale.
The recurring contractor story sits underneath it.
Locomotives have to remain available. Wagons have to remain safe and serviceable. Workshops need capacity. Track and signalling need reliability. Traincrew and network paths have to line up. Mine loadouts and export terminals have to stay coordinated.
The agreement therefore helps underpin a wider rail-services, maintenance and logistics ecosystem that sits between Bowen Basin production and international steelmaking-coal markets.
For BBI readers, the useful question is not “what is the contract worth?”
It is: what assets and services must remain available for Aurizon to reliably move up to 37Mt every year?
