The 44 class are a class of diesel-electric locomotives built by AE Goodwin, Auburn for the New South Wales Government Railways between 1957 and 1967.

The 44 class were built by Alco's Australian licensee AE Goodwin, and are based on the Alco DL500B model. The locomotives are fitted with Alco 12-251B engines, developing 1343 kW. They were built in two batches, the first 60 between July 1957 and April 1961 and the second 40 between October 1965 and December 1967. The last 40 had Associated Electrical Industries as opposed to General Electric generators and traction motors as well as illuminated segregated number boxes at the No.2 end.

During their career these locomotives have served every part of New South Wales and operated every type of train. They are very similar to the South Australian Railways 930 class.

With driving cabs within both ends, the front (No.1 end) of the locomotive had a rounded nose (however not as round as the Clyde/GM "Bulldog nose" type) and a flat nose at the No.2 end.

Withdrawals started in the late 1980s of some earlier examples in need of rewiring, however many survived into the 1990s with the last being withdrawn in July 1997. The State Rail Authority still had over forty on its books that were auctioned in December 1994.

While most were scrapped, a number saw service with other freight operators. Chicago Freight Car Leasing Australia, Great Northern Rail Services, Independent Rail of Australia, Silverton Rail and Southern Shorthaul Railroad all operated 44s with most ending up with Qube Logistics until their withdrawal in 2014.
