- BHP has run two Wabtec FLXDrive battery-electric locomotives on its Jimblebar-to-Port Hedland ore route in the Pilbara for nearly a year, with the source reporting the units are 'ready for prime time.'
- Wabtec's FLXDrive locomotives each deliver 4,400 hp from a 7 MWh battery pack, using high-torque electric motors instead of diesel generators to haul up to 35,000 tonnes of ore.
- Regenerative braking on long downhill loaded runs can recapture enough energy to send the unladen train back uphill for reloading, meaning the locomotives could effectively need only a single charge to keep cycling.
- BHP announced it commissioned the two FLXDrive units in Port Hedland in FY2026 and is bringing two Progress Rail BELs — delivered to Perth in FY2026 — to Port Hedland for commissioning in FY2027.
- Peter Thomas, Wabtec's Regional Senior Vice President for ANZ & SEA, framed the Pilbara deployment as a step toward decarbonizing rail operations in 'one of the world's most demanding environments.'
- Wabtec released a new video explainer for the FLXDrive program, which the article embeds above the original August coverage.
Why it matters: Mining heavy-haul rail is one of the largest diesel sinks on the planet, and BHP's near-year-long successful trial of 4,400 hp battery-electric locomotives — plus its decision to add Progress Rail units for FY2027 side-by-side evaluation — moves BELs from demonstration toward fleet-scale operation. The regenerative-braking math (downhill loaded runs powering empty returns) could fundamentally change fuel-cost economics for any mine with favorable topography.
