The investigation into the derailment of train 6MP9 train near Cook, South Australia on 6 January 2019 is continuing.

The report into the investigation is currently in the ‘Final Report: Drafting’ phase. The dynamic and complex nature of investigations means that during the drafting of the report it may be necessary to return to the evidence collection or examination and analysis phases of an investigation. There will often be significant overlap in time between the evidence collection, examination and analysis and final report drafting phases.

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

  • an independent examination report on a ruptured wheelset from the occurrence
  • relevant industry inspection standards and procedures.

Currently, publication of the final report is anticipated during the second quarter of 2020.
