Investigation in progress


On 16 June 2020, freight train 2BW4 was operating between Brisbane, Queensland and Port Kembla, New South Wales. As train 2BW4 was passing through Dungog station in New South Wales, workers nearby reported a wagon made contact with the platform. This information was communicated to the train driver and the train was diverted in to the loop at Wallarobba. 

Inspection of the train detected the platform on the 35th wagon (RKOX4055Y) was detached and resting on the bogie bolster. Train 2BW4 consisted of three locomotives and a rake of 53 wagons with 24 empty wagons in front of wagon RKOX4055Y and 9 empty wagons behind in the consist.

Damage was reported on Grafton, Taree and Dungog platforms, suspected to be a result of the out-of-gauge wagon on train 2BW4.

An ATSB investigation is being undertaken by officers from the NSW Office of Transport Safety Investigations, under the provisions of the Transport Safety Investigation Act 2003. Investigators have commenced collecting evidence from involved parties.

Should any safety-critical information be discovered at any time during the investigation, the ATSB will immediately notify operators and regulators so appropriate and timely safety action can be taken.

A final report will be published at the conclusion of the investigation.
