3000 class (Adelaide). The 3000 class are a group of ten Clyde-built diesel-electric locomotives constructed for the Australian National Railways Commission (AN) between 1978 and 1979. Based on the EMD GT26CW-2 model, they were designed for heavy freight and passenger duties on the broad gauge network radiating from Adelaide. The class served Australian National and its successors for over four decades, becoming a familiar sight on key routes like the Adelaide–Melbourne railway line and the Adelaide–Port Augusta railway line.
The 3000 class was ordered by Australian National in the late 1970s as part of a fleet modernization program to replace older locomotives such as the 900 class and B class units. The contract was awarded to Clyde Engineering's Granville workshops, which constructed the locomotives under license from GM-EMD. Their introduction coincided with the expansion of intermodal services and the operation of prestigious passenger trains like The Overland between Adelaide and Melbourne. The class's arrival significantly boosted the haulage capacity of Australian National on the critical South Australian broad gauge network.
The 3000 class is a Co′Co′ configuration locomotive, built on the robust GT26CW-2 frame. It is powered by a single EMD 16-645E3 V16 diesel engine, producing 2,460 kW (3,300 hp), which drives a D77 DC main generator supplying power to six D29 traction motors. This powertrain was proven in other Australian designs like the 82 class and the N class. Key features include a modular, North American-style full-width cab for crew comfort, dynamic brakes for mountain descents, and a maximum speed of 115 km/h. The locomotives were equipped with Westinghouse air brakes and initially delivered with multiple-unit train control capabilities for working in tandem with other AN classes like the 830 class.
Upon entering service, the 3000 class was immediately deployed on the most demanding AN freight and passenger assignments across South Australia. They were the primary motive power for The Overland for many years, also hauling the Indian Pacific on the Port Augusta leg prior to the completion of the standard gauge line. The class worked extensively on bulk freight, including grain and mineral services from Eyre Peninsula and the Mid North to Port Adelaide. Following the privatisation of Australian National in 1997, the entire class was acquired by Australian Southern Railroad (ASR), later Genesee & Wyoming Australia (GWA). Under Pacific National and later One Rail Australia (ORA) ownership, they continued on interstate freight, particularly between Adelaide and Melbourne, until their gradual withdrawal in the 2020s.

The 3000 class was delivered in the striking Australian National "candy" livery: a deep Indian red body with a broad, almond-shaped candy apple red stripe outlined in white, running the length of the locomotive. This scheme was identical to that applied to contemporary AN locomotives like the AL class and the BL class. Following the takeover by ASR, most units were repainted into that company's dark blue and yellow scheme. Under GWA and ORA, surviving locomotives received the respective corporate liveries of Pacific National (navy blue and yellow) and One Rail Australia (white, red, and black). Number 3001 was restored to its original AN "candy" colors for preservation at the National Railway Museum, Port Adelaide.
