These units were obtained to meet the growing demand for iron ore and an expanding railway network in the Pilbara region of Western Australia. They entered service with Pilbara Iron, which has since become Rio Tinto Iron Ore. The ES44DCi model provided greater fuel efficiency and lower emissions than earlier locomotives, as well as larger cooling systems to cope with the hot temperatures experienced in the Pilbara. The letters ‘ES’ in the model designation refers to ‘Evolution Series’. All 100 members of the class remain in service.
