Abstract
At about 1655 on Tuesday 11 November 2008, freight train 2PM6 derailed on the Nullarbor Plain approximately 11 km west of Loongana in Western Australia. There were no injuries as a result of the derailment but there was significant damage to rolling stock and track. The investigation found that the combined effects of atmospheric wind and induced wind due to train movement was likely to have been sufficient to initiate the overturning and subsequent derailment of a lightly loaded, double stacked wagon and other vehicles. Two safety issues were identified relating to the suitability for double stacking of certain wagon types, particularly in high-wind operations, and maintenance of container securing mechanisms. The train operator has taken safety action to address those issues.
