At about 0618 on Thursday 25 November 2010, freight train (4DA2) operated by FreightLink Pty Ltd derailed on the Central-Australia Railway line, near the 826 km mark, about 5 km south of Cadney Park in South Australia.

There were no injuries as a result of the derailment but there was significant damage to rolling-stock and about 300 m of track required replacement.

The investigation determined that a severe weather event, very strong winds associated with thunderstorm activity, were of a sufficient magnitude to initiate the rollover and subsequent derailment of a group of lightly loaded double-stacked container wagons.

A number of minor safety issues were identified as a result of the investigation and have been brought to the attention of Genesee & Wyoming Australia Pty Ltd (GWA). These issues primarily relate to the wind effect on lightly loaded/high vehicles (particularly double-stacked containers) and the identification of and response to severe weather events.

Safety issues

RO-2010-012-SI-01 - RO-2010-012-SI-02 -  

Effects of wind load on rail wagons

Double stacked container wagons are at particular risk of wind induced roll-over. This is a direct relationship of exposed side area, and was therefore probably exacerbated by out of gauge/high loads on some wagons with a large surface area exposed to the gust front.
