Queensland Railways 1600 class

The Queensland Railways 1600 class was a class of eighteen diesel branch line locomotives built by English Electric at Rocklea for Queensland Railways between 1962 and 1964. They were ordered in two contracts, twelve and then six, and delivery was delayed because the first four came out over the design weight, so numbers 1604 and 1605 were the first to enter service. The locomotives were based at Alpha in Central West Queensland and at Roma, were used for shunting around the state, and were soon all based at Alpha. The 1620 class followed as a development of them. The class was withdrawn in 1991 and five locomotives have been preserved, held by railway societies and museums in Queensland and Victoria.
