The 1502 class was a class of diesel locomotives built by Clyde Engineering, Eagle Farm for Queensland Railways between 1967 and 1969.
The 1502 class was an evolution of the 1460 class fitted with a more powerful Electro-Motive Diesel 645E engine and upgraded generators and traction motors.[1] They operated services in South East Queensland including suburban trains in Brisbane.[2]
In 1996, four were sold to Tranz Rail in New Zealand. After rebuilding at Hutt Workshops, they were placed in service with the Australian Transport Network in Tasmania as the DQ2000 class.[3][4][5]
All had been withdrawn by 1999. In 2002, six were overhauled and fitted with 1,435 mm (4 ft 8+1⁄2 in) standard gauge bogies from FreightCorp 49 class locomotives for use by Interail in New South Wales as the 423 class.[6][7]
In 2005, seven have been exported to Ferrocarril de Antofagasta a Bolivia, Chile.[2] In 2006, two were rebuilt and transferred to Australian Railroad Group for use in Western Australia as the AD class.[8]
