The ATSB is investigating a derailment involving loaded grain train 3966 near Dombarton, New South Wales on 15 December 2020

At approximately 0454, the train crew reported they had lost brakes on the decent of the Moss Vale to Unanderra rail line and were gaining speed. The loaded grain train derailed near Dombarton, New South Wales. The train had parted in three sections as a result of the derailment. The train crew advised they had brought the two locomotives and the remaining two wagons to a stand at Farmborough Heights.

As part of the investigation, the ATSB will interview the train crew, obtain and analyse the train data logger report, radio communications recordings, track and rolling stock maintenance and inspection records, and gather additional information.

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

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.
