The 6000 Class units use the C44aci production model first used with the 92 Class, but since used with other locomotive classes throughout Australia. Twelve units entered service in 2009 and 2010, and additional five arrived in 2017 and 2018. They have been used in a range of duties, including Hunter Valley coal working and Melbourne-Adelaide intermodal service. Six members of the class were reclassified as ACA Class for use in Western Australia, but later returned to their original designation.
