Infinity Train Completes First 1,100-Kilometer Test and Moves Into Next-Stage Trials

Fortescue Zero’s regenerative-braking prototype will undergo rigorous real-world evaluations before full-scale deployment on the Pilbara freight line later in 2025.

Overview

  • The Infinity Train uses downhill regenerative braking to recharge its batteries without external power or diesel fuel.
  • In its inaugural trial the electric prototype covered 1,100 kilometers between Perth and the Pilbara entirely on recovered energy.
  • Fortescue Zero estimates a full fleet could save about 82 million liters of diesel and cut roughly 235,000 tons of CO₂ emissions each year.
  • The Pilbara’s 620-kilometer downhill grade from mine to port allows the train to generate more energy than it consumes on the uphill return trip.
  • Following a series of performance tests this year, Fortescue plans to launch the system on its main Pilbara corridor and offer the design to other operators.
