A preliminary report has detailed factual information established in the early evidence collection phase of the ongoing investigation into the derailment of a freight train near Geelong, Victoria on the morning of 14 November 2022.
The transport safety investigation is being conducted by the Chief Investigator, Transport Safety, who conducts rail investigations in Victoria on behalf of the Australian Transport Safety Bureau.
The report notes that the freight train was travelling at about 80 km/h over a culvert near Inverleigh, west of Geelong, when 16 of its 55 wagons derailed.
Significant rainfall was recorded at Inverleigh in the 12-hour period prior to the derailment, and the embankment supporting the track at the location of the culvert collapsed.
The incident resulted in substantial track damage, and 16 destroyed wagons. There were no injuries.
“Since attending the derailment site and completing a site and train inspection, investigators have examined drainage in the waterway catchment area and commenced hydrology studies,” Chief Investigator, Transport Safety Mark Smallwood said.
“Investigators have also examined operational information, conducted interviews, and commenced collecting other relevant information.”
Mr Smallwood said investigation will further review the waterway catchment, weather warnings in the area, the effect of prior rainfall on soil moisture and catchment flow and culvert design, including capacity.
Investigators will also review maintenance of track infrastructure and train operation.
A final report will be released at the conclusion of the investigation.
“However, should a critical safety issue be identified during the course of the investigation, relevant parties will be notified immediately, so appropriate and timely safety action can be taken,” Mr Smallwood said.
