Runaway coal train hit 90km/h on 20km journey in Australia's Hunter Valley

An unmanned coal train traveled 20 kilometers through New South Wales' Hunter Valley at speeds reaching 90 km/h before coming to a halt, according to an interim report.

The Pacific National train, consisting of three locomotives and 96 wagons, began moving from Newdell Junction on July 25. The Office of Transport Safety Investigations (OTSI) found the train reached speeds significantly exceeding the safe operating limit of 60 km/h for loaded coal trains.

After its uncontrolled journey, the train began rolling backward for 5 kilometers, eventually stopping between two level crossings near Glennies Creek. The report noted damage to rolling stock and minor damage to the track.

Investigators are examining locomotive and braking systems, data loggers, CCTV footage, and the actions of the train crew. They will also review organizational processes for responding to train brake faults, operating procedures, maintenance systems, and incident response systems. The chief investigator aims to determine how and why the train ran away and if the incident could have been anticipated. Pacific National is cooperating with the investigation, stating that safety is its highest priority.
