The New South Wales 45 class are a class of diesel-electric locomotives built for and operated by the New South Wales Government Railways from 1962. The number grouping was previously occupied by a single electric locomotive numbered 4501, which was renumbered 7100 to free up the grouping.

The 45 class were built by the Alco's Australian licensee A.E Goodwin, and are based on the Alco DL-541 model. The South Australian Railways also has similar units, and are classified as the 600 class. The locomotives are fitted with an Alco 12-251C engine, developing 1455 kW, the same as the 44 class. Six of these locomotives have been upgraded in the cabs, and reclassified as the 35 class. Some also had a unique 'red terror' type of livery to distinguish the units.
These hood units were introduced into service in 1962, and initially serviced the Main Southern line, but moved to the North and Northwest of the state later on, as with the other Alco units.
