Post-incident inspection of the derailment site identified a number of factors that increased the risk of a derailment in the refuge and main line. ARTC’s maintenance activities had identified some but not all of these factors prior to the derailment.
Safety action taken: ARTC undertook restorative work following the derailment and repaired the section of track.
The ATSB notes that the action taken will addresses the immediate safety issue, but does not resolve the underlying factors that contributed to the safety issue.
