The R Class are diesel locomotives built by English Electric, Rocklea for the Western Australian Government Railways in 1968. They were followed by the revised RA class.
The R class were a hood type general purpose diesel-electric locomotive. They were similar to the Queensland Railways 1300 class. All equipment, except traction motors, were interchangeable with the standard gauge K class. The bogies are an English Electric design with low weight transfer characteristics. They feature fully equalised primary spring gear, all traction motors in each bogie mounted with the nose-suspension facing inwards, traction thrust at near axle level and long pivot centres to reduce inter-bogie transfer. Adhesion loss at maximum tractive effort is limited to 4.5 per cent allowing 1,830 long tons (1,860 t; 2,050 short tons) trailing load to be hauled up a 1 in 100 grade. [1]
In 1968 the Western Australian Government Railways took delivery of five narrow gauge versions of the K class for use on bauxite traffic, the last three being fitted with 6 tonnes (5.9 long tons; 6.6 short tons) of ballast to improve their tractive effort. All were fitted with dynamic brakes. [2] [3] [4]

The X class is a class of diesel locomotives built by English Electric for the Tasmanian Government Railways between 1950 and 1952. They were the first class of diesel locomotive to enter mainline service on a Government-owned railway in Australia.
B-B and Bo-Bo are the Association of American Railroads (AAR) and British classifications of wheel arrangement for railway locomotives with four axles in two individual bogies. They are equivalent to the B′B′ and Bo′Bo′ classifications in the UIC system. The arrangement of two, two-axled, bogies is a common wheel arrangement for modern electric and diesel locomotives.
The WAGR X class is a now-withdrawn class of diesel locomotives built by Beyer, Peacock & Company and Metropolitan-Vickers, Bowesfield Works, Stockton-on-Tees for the Western Australian Government Railways (WAGR) between 1954 and 1956. Several members of the class have been preserved.
The Y class are a class of diesel locomotives built by Clyde Engineering, Granville for the Victorian Railways between 1963 and 1968.
The New South Wales AD60 class were Beyer-Garratt patent articulated four-cylinder, simple, non-condensing, coal-fired superheated, 4-8-4+4-8-4 heavy goods steam locomotives built by Beyer, Peacock & Company for the New South Wales Government Railways in Australia.
The K class are a class of diesel locomotives built by English Electric, Rocklea for the Western Australian Government Railways between 1966 and 1969.
The L Class are a class of diesel locomotives built by Clyde Engineering, Granville and Eagle Farm, and Commonwealth Engineering, Rocklea for the Western Australian Government Railways between 1967 and 1973.
The GT42CU AC is a model of diesel electric locomotives manufactured by EDi Rail, Maryborough between 1999 and 2005 under licence from Electro-Motive Diesel, for use on narrow gauge railways in Queensland.
The South Australian Railways 930 class was a class of diesel-electric locomotives built for the South Australian Railways between 1955 and 1967 by AE Goodwin, Auburn, New South Wales, the Australian licensee of the American Locomotive Company (Alco). Based on the Alco DL500B World series model, they were fitted with Alco 12-251B four-stroke V12 turbocharged diesel engines that developed 1600 horsepower for traction. The first six of the class had a driving cab at one end only; the remaining 31 locomotives had two. The latter series, up-rated, were the basis of the almost identical New South Wales 44 class, of which 100 were built from 1957.
The 500 class were a class of South Australian Railways diesel shunter locomotives built at Islington Railway Workshops between 1964 and 1969.
The BHP Newcastle 37 class were a class of diesel locomotives built by A Goninan & Co, Broadmeadow for the BHP's, Newcastle Steelworks between 1960 and 1983.
The T class was a class of diesel locomotives built by Tulloch Limited, Rhodes for the Western Australian Government Railways between 1967 and 1970.
The F class were a class of diesel locomotives built by English Electric, Rocklea for the Midland Railway of Western Australia in 1958. They were later sold to the Western Australian Government Railways.
The C class are a class of diesel locomotives built by English Electric, Rocklea for the Western Australian Government Railways in 1962.
The WAGR A/AA/AB classes are classes of diesel locomotives built by Clyde Engineering, Granville, New South Wales, Australia, for the Western Australian Government Railways (WAGR) between 1960 and 1969.
The D/DA class are a class of diesel locomotives built by Clyde Engineering, Granville for the Western Australian Government Railways in 1971-1972.
The 1270 class were a class of diesel locomotive built by English Electric, Rocklea for Queensland Railways between 1964 and 1966.
The 1502 class was a class of diesel locomotives built by Clyde Engineering, Eagle Farm for Queensland Railways between 1967 and 1969.
The Z class are a class of diesel locomotives built by English Electric Rocklea for the Tasmanian Government Railways in 1973. They were a development of the WAGR RA class and were the last of a line of very successful locomotives fitted with the English Electric 12CSVT Mk II engine.
The RA Class are diesel locomotives built by English Electric, Rocklea for the Western Australian Government Railways between 1969 and 1972. They were a revised version of the R class.
