The ATSB is investigating the derailment of Pacific National operated freight service 1221 (loaded garbage waste train).

The train derailed in a John Holland Rail controlled network near Lake Bathurst (adjacent to Inveralochy Siding Road). The derailment site is located between Goulburn and Tarago, NSW.

A wheel bearing assembly of the trailing axle of the lead bogie of wagon RQEY1962D failed. This caused the trailing wheel/axle of the lead bogie to derail for a distance of approximately 2,500 m. There were no reported injuries to staff or members of the public. Wagon RQEY1962D suffered damage to the lead bogie and frame with minor damaged to track infrastructure.

This investigation is being led by the  NSW Office of Transport Safety Investigations (OTSI). OTSI conducts rail investigations in NSW on behalf of the ATSB under 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.
