At about 0415 on 8 October 2010, freight train 5MP5 travelling from Melbourne to Perth reported having derailed on the Defined Interstate Rail Network (DIRN) between Wirrega and Keith in South Australia.

No one was injured and there was only minor damage to rolling-stock during the derailment, however approximately 400 m of track required repairs before services could resume and 2900 concrete sleepers were subsequently replaced to restore track integrity.

It was established that the derailment was the result of a screwed journal on the 12th wagon (RQJW 22034D) in the consist behind the locomotives.
