Preliminary report released 21 July 2011
At about 2016 on Friday 6 May 2011, freight train 4PM6 derailed the trailing bogie of the 49th wagon (RQHY 07069C) at Port Augusta, South Australia near the Carlton Parade level crossing (91.559 km). About 1300 m later, the wagon re-railed itself as it entered the road pavement near the Stirling Road level crossing. There were no injuries as a result of the derailment but there was minor damage to rolling stock and track. The investigation is reviewing a number of factors including the condition of the track and rolling stock, train speed and the interaction of rail wagons and the track through this location.
