# Rio Tinto Iron Ore: AutoHaul autonomous heavy-haul rail

Mainline driving can be automated while exceptions move to remote operations.

Function: Logistics. Patterns: Exception-based operations; Autonomous with a backstop. Evidence: reported.

Freshness: current. Reviewed: 2026-08-23. Updated: 2026-08-22.


Source quality: 2 primary; publication outcomes are reported.

## Before

1. **Train driver** — Drives the heavy-haul train between mine and port until the 12-hour shift limit. (control: Rail rules and onboard safety systems.)
2. **Relief crew and road vehicle** — Travels to the train for mid-journey driver changes, requiring about 1.5 million road km annually. (control: Published sources quantify road exposure but do not provide baseline injury count.)

## After

1. **AutoHaul onboard control** — Controls speed, braking, and responses to restrictions and alarms across the private mainline. (control: Automatic train protection, onboard cameras, and upgraded crossings.)
2. **Remote rail operators** — Monitor missions and manage stops, alarms, and network exceptions. (control: Human network authority; exception latency and intervention thresholds are not published.)

## Decision rights

Automation drives routine missions; remote control owns network decisions.

## Exception path

Stopped missions and alarms follow rail-safety control procedures.

## Outcomes

- **Driver-transfer road exposure** (reported): About 1.5 million km/year → Road travel eliminated. Avoided exposure, not injuries prevented.

## Executive lesson

Automation removed the shift-change handoff, not network control.

## Anti-pattern

Do not infer injuries prevented.

## Questions for leaders

- Where is the operating threshold set and who can override it?
- What measured result would trigger rollback or retraining?
- Which residual decisions must remain human-owned?
