The 422 class are a class of diesel locomotives built by Clyde Engineering, Granville for the New South Wales Government Railways in 1969/70.
The 422 class were the first Australian locomotives built with non-streamlined dual cab bodies. Manufactured by Clyde Engineering, Granville, they were introduced into service on the Main South and Illawarra lines where they would spend most of their New South Wales careers hauling passenger and freight services. Among the services they hauled were the Canberra Express, Intercapital Daylight, South Coast Daylight Express, Southern Aurora, Spirit of Progress and Sydney/Melbourne Express.
In 1980 42220 was rebuilt by Clyde Engineering, Rosewater, receiving an AR16 alternator, a new electrical system and Super Series wheel slip technology. It was a test bed for many of the features incorporated into the 81 class.
From 1982 they began to operate through to Melbourne. This ceased in February 1990 when non air-conditioned locomotives would no longer be accepted by Victorian drivers.
With the formation of National Rail, the 422s were all allocated to the new interstate carrier in July 1995 pending delivery of its NR class locomotives. This saw them again frequently operating to Melbourne, albeit usually as second units and over new territory to Parkes via Forbes and from August 1996 via the North Coast line to Brisbane. When they were returned to FreightCorp in September 1997, their Southern duties were now being handled by Class 81s so most were stored.
