In Australia's Pilbara region, Rio Tinto manages an extensive system of 17 iron ore mines and four port terminals, all linked by an extensive rail network. In 2019, Hitachi Rail will work with Rio Tinto to introduce AutoHaul™, the world's first fully autonomous heavy-haul rail operation, facilitating the movement of approximately one million tonnes of iron ore per day. Monitored remotely from an operations centre in Perth, the 2.4-kilometre-long trains travel over 1,900 kilometres of track, transporting iron ore from mine to port. In parallel with AutoHaul™, a major project was launched to upgrade the Integrated Control and Supervision System (ICSS) that supports the network's operations.
The three-year project will replace the existing MicroTrax ICSS with Hitachi Rail's MicroLok II to improve network throughput, on-time performance and lifecycle efficiency. The ICSS is the technology platform for integrated train control, monitoring and subsystem supervision. The MicroLok II computer-based interlocking system handles key wayside functions, ensuring the safe and efficient movement of freight across multiple tracks and crossings. Its advanced technology includes train detection, track circuit integrity, coded communication, cab signalling, event recording and vital interlocking code.
The completed ICSS Phase 1 and Phase 2 projects replaced the existing interlocking system and supporting wayside equipment on 100 kilometres of the Tom Price line and 200 kilometres of the Yandi line.
Phase 3 will now focus on the Paraburdoo line and is expected to be operational in 2025.
