The 422 class diesel electric locomotive were introduced into the New South Wales rail system in 1969. Clyde Engineering of Granville, New South Wales obtained the contract to build 20 of these units.
The class have an EMD 16-645E engine, developing 1,640 kW (2,200 hp), with a maximum speed of 124km/h. They operate on standard gauge, have a Co-Co wheel arrangement, have a length of 18.44 m and have a mass of 110 t. In 1980, the 42220 was rebuilt by Clyde Engineering, having its generator replaced with a EMD model AR16-D14, and equipped with EMD's dash-2 electrics and “Super Series” wheel slip technology. It was in effect, a test bed for many of the features incorporated in to the 81 class.
The 422 class were trouble-free riders, and spent their time usually operating services in the South. They have been used for services such as the famous Southern Aurora, Intercapital Daylight, Spirit of Progress and Sydney/Melbourne Express, double heading or occasionally be coupled to a 421 class instead of another 422. The class can also be seen frequently double heading freight services between New South Wales and Victoria.
Following the introduction of newer locomotives, the older locomotives of New South Wales State Rail Authority were phased out in favour of newer ones. None were preserved nor scrapped, but have been sold to various other rail companies, and in most cases, renumbered.
- 16 have been sold to Australian Railroad Group.
- 2 have been sold to CFCLA.
- 2 have been sold to Northern Rivers Railroad, and then to Queensland Rail subsidiary Interail.
