Doolan's Heavy Haulage delivered the four stored CM40-8M model locomotives to Roy Hill's Flash Butt yard on the 2nd of December 2017. The units were then tested on the 22nd of December, before CD4302 was used to power the loaded fuel train from Tad Yard (Boodarie) to Roy Hill mine. And the units have been in service ever since.
