The 45 class are a class of diesel-electric locomotives built by AE Goodwin, Auburn for the New South Wales Government Railways between 1962 and 1964.
The 45 class were built by Alco's Australian licensee AE Goodwin, and are based on the Alco DL-541 model. They initially entered service on the Main Southern line but later operated on all main lines. One was destroyed in a collision in May 1972.
From June 1984 the Australian Federated Union of Locomotive Enginemen placed a ban on the class as leading locomotives, meaning they could only be used as second locomotives, although they were able to be used on Sydney metropolitan trip and Liverpool Range banking duties.
Six were fitted with upgraded cabs and modified bogies at Cardiff Workshops in 1989 and reclassified as class 451s and later class 35s, allowing them again to be used as lead locomotives, although they spent most of their time being used as Liverpool Range bankers and Yeerongpilly, Brisbane shunters. Following a poor wheat crop, the Class 45s were placed in store at Junee Locomotive Depot in December 1991. A locomotive shortage saw most return to service from March 1993. They remained in service until replaced by FreightCorp by Class 82s in 1994/95.
Thirty-two were auctioned in December 1994 with most being sold for scrap. One was retained by the State Rail Authority as a designated heritage locomotive while four were transferred to Rail Services Australia before being sold to Great Northern Rail Services in 2000. One remains in service with Greentrains.
