ALCO DL531

The ALCO DL531, also sold as the RSD-8, was a road locomotive design of the American Locomotive Company that was built and run in several countries. Its best known production came from Australia, where the Alco licensee A E Goodwin of Auburn built 295 of them between 1958 and 1970. The New South Wales Government Railways bought 165 as its 48 class, the largest diesel class it ever owned, and South Australian Railways took its 830 class in batches over the same years. Silverton Rail bought three narrow gauge units. The type also worked in Brazil, Pakistan and Peru, and a four-axle relative, the DL532 or RS8, ran in Jamaica, Greece and South Korea.
