First entering service with the Department of Railways in New South Wales in 1959, the 48 Class eventually comprised 165 units, which made them for many decades the most numerous of any class of diesel locomotive in Australia. Units 4886–165 had larger fuel tanks than earlier deliveries. Designated branch line units, they provided reliable service in a range of duties, including freight and passenger work. Seven were rebuilt as the PL Class and others have been renumbered. Numerous members of the 48 Class remain in service with various operators.
