These units were the most powerful diesel locomotives in Australia upon beginning service in 1995 with Hamersley Iron in the Pilbara region of Western Australia. Hamersley Iron later merged with Robe River to become Pilbara Rail, then later Pilbara Iron, which is owned by Rio Tinto Iron Ore. Further C44-9W locomotives were obtained until 2006, eventually bringing the total to 72. All class members remain in service throughout Rio Tinto Iron Ore’s Pilbara network.
