The most advanced electric locomotives on the planet have already begun operating in Australia, revolutionizing industrial mobility.
Manufactured by Progress Rail for the mining company Fortescue, these machines feature 14.5 MWh batteries, the largest installed in mobile land vehicles.
Currently, these are used to transport iron ore from the mines.
Thus, the deployment of two units will allow for a reduction of around one million liters of diesel per year in one of the most energy-intensive industries.
Record-breaking batteries for heavy rail transport
Built in Sete Lagoas, Brazil, these electric locomotives are part of Fortescue’s plan to achieve zero operational emissions in the Pilbara region before the end of the decade.
The decision was made over two years ago, when this type of solution still generated skepticism.
Each locomotive has eight axles and a capacity of 14.5 MWh. This makes them the largest mobile land batteries in the world.
It’s not just about size: they incorporate regenerative braking capable of recovering up to 60% of energy during loaded descents.
In mining routes, with steep slopes and tons of material, that makes a difference.
The recharging is done at 2.8 MW, allowing for quick rotations without stopping the operation for hours.
Moreover, the electricity used comes from the company’s own renewable installations.
The main features of the electric locomotives
- Battery capacity: 14.5 MWh per unit
- Regenerative braking: recovers up to 60% of energy
- Recharging power: 2.8 MW
- Axles: 8 per locomotive
- Diesel reduction: 1 million liters annually between both units
- Energy: 100% renewable from own installations
Australia leads the transition in mining
The electric locomotives began operating on real mineral transport routes, a harsh, remote, and demanding environment.
Precisely where classic electrification via catenary is complex, expensive, or directly unfeasible.
Although the delivery was initially scheduled for 2023, it was finally completed this year. The first locomotive arrived in June and the second just a few weeks ago.
Both landed in Port Hedland before heading to the Pilbara mining complex. “They are not concepts,” stated Dino Otranto, CEO of Fortescue.
And he reinforced: “They are operational assets that are redefining what is possible in heavy rail transport.”
Fortescue is not alone on this path. Other Australian mining companies are following the same route towards decarbonization.
Earlier this month, BHP received its own battery-powered electric locomotives, manufactured by Wabtec.
In this case, with a capacity of 7 MWh and also with energy recovery systems.
These units will soon begin operating in real conditions. If they meet expectations, the message will be clear: heavy rail can be electrified without waiting for large infrastructures.
The impact of electric locomotives on industrial decarbonization
These locomotives are not going to save the climate on their own, but they mark a realistic path. They demonstrate that the energy transition is not just solar on rooftops or urban electric cars.
It’s also about steel, minerals, logistics, and bold industrial decisions. In the short term, they can accelerate the replacement of diesel locomotives on mining, forestry, or industrial routes.
In the medium term, their logic could extend to non-electrified rail corridors on other continents. This would reduce emissions without waiting decades for new infrastructures.
And in the long term, combined with local renewables, stationary storage, and smart grids, these solutions can decarbonize one of the most challenging links in the energy chain. It’s not epic, it’s practical.
