The ATSB’s rail safety investigation role occurs concurrently with the Office of the National Rail Safety Regulator.
The ATSB investigates selectively. When the ATSB investigates an accident or incident, investigators will seek to determine its circumstances, identify any safety issues, and encourage relevant safety action. The aim of all ATSB investigations is to prevent the occurrence of other accidents and incidents, rather than to assign blame or liability.
