Queensland Railways 1502 class

The 1502 class was a class of diesel locomotives built by Clyde Engineering, Eagle Farm for Queensland Railways between 1967 and 1969.

History
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. They operated services in South East Queensland including suburban trains in Brisbane.

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.

All had been withdrawn by 1999. In 2002, six were overhauled and fitted with bogies from FreightCorp 49 class locomotives for use by Interail in New South Wales as the 423 class.

In 2005, seven have been exported to Ferrocarril de Antofagasta a Bolivia, Chile. In 2006, two were rebuilt and transferred to Australian Railroad Group for use in Western Australia as the AD class.
