Update: 26 September 2019

The investigation into the derailment of coal train MR336 at Antienne, NSW on 26 September 2018 is continuing.

ATSB investigators have so far gathered and analysed numerous information sources including:

  • Train Data Loggers
  • Interviews
  • Post-derailment photographs and measurements
  • Unit train consists
  • Loading point systems.

The investigation is currently in the examination and analysis phase. During this phase, evidence is reviewed and evaluated to determine its relevance, validity, credibility and relationship to other evidence and to the occurrence. ATSB investigators may:

  • undertake detailed data analysis
  • create simulations and reconstruct events
  • examine company, vehicle, government and other records
  • examine selected wreckage in the laboratory and test selected components and system
  • research scientific literature related to human factors associated with the evidence
  • review specialist reports (such as meteorology, component examination, post-mortem report and toxicology reports)
  • conduct further interviews, and
  • determine the sequence of events.

Once the examination of the evidence is complete, the investigation team will test a series of hypotheses to arrive at a number of safety factors that could have contributed to the transport safety occurrence or issue, or otherwise increased safety risk.  

The investigation team then convenes a Safety Factor Review with ATSB management. This is a rigorous internal review of the progress of the investigation, its preliminary findings and focus. The Safety Factor Review involves the investigation team presenting their evidence and analysis to reach consensus on the investigation findings. Once consensus is achieved, the report drafting phase of the investigation can begin.

Currently, the anticipated completion and publication release date of the final report is during the fourth quarter of 2019. However, should any critical safety issues be identified during any phase of this investigation, the ATSB will immediately notify those affected and seek safety action to address the issue.

Summary

The ATSB is investigating the derailment of coal train MR336 at Antienne, New South Wales on 26 September 2018.

At approximately 1200, Pacific National Coal Train MR336 travelling towards Newcastle derailed near Antienne on the Up Main line. The derailed trailing bogie on the 25th wagon was ejected into the path of the adjacent track. An Aurizon train, WC195, travelling in the opposite direction collided with the bogie.

The ATSB has commenced an investigation into this accident, which will be 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 and statements from involved parties, which will be analysed and a draft investigation report compiled.

A final report will be released at the end of the investigation.

Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify those affected and seek safety action to address the issue.
