The 442 class are a class of diesel locomotives built by AE Goodwin and Comeng, Auburn for the New South Wales Government Railways between 1970 and 1973.

The 442 class were ordered and operated by the New South Wales Government Railways. They were the second generation of Alco units to be built, and were used on both main freight and passenger service in New South Wales. Since entering private ownership they have operated across Australia. They are identical to the South Australian Railways 700 class. They were nicknamed Jumbos, due to their 1971 delivery coinciding with that of Qantas' first Boeing 747s.

The 442 class were built from 1971 to replace the 40 class locomotives dating from 1951, as they could not be economically rebuilt to modern standards. Twenty locomotives were initially ordered from AE Goodwin, the contract stipulating that the 40 class be accepted as a trade in, with some parts from the older units used for the new locomotives. The contract was later extended by 20 units.

The first locomotive was completed in October 1970 but was rejected due to rough riding concerns in testing, with five months passing before it was finally accepted after modifications to the bogie design. After AE Goodwin was placed in administration it was sold to Comeng who completed the last six locomotives with a Mitsubishi alternator in lieu of a generator.

The 442 class operated mainline services across the state. In 1985 some (including 23-27, 29 & 30) were fitted with V/Line radios to allow them to operate services through to Melbourne. This ceased in 1987 with those fitted being sent to Melbourne to have the equipment removed.
