The WAGR W class is a class of 4-8-2 steam locomotives operated by the Western Australian Government Railways (WAGR) between 1951 and 1972.
The class was first proposed by Chief Mechanical Engineer Frederick Mills in 1947. However, the death of Mills in 1949 put a hold on the project, with his successor Charles Clarke, taking up the project on his appointment later that year.
Mills had requested Beyer, Peacock & Co to reserve capacity for their construction when the design was first proposed, however, by the time Clarke took over, Beyer, Peacock & Co had identified a number of possible problems with the design. This led to a meeting in the United Kingdom in 1950, the outcome of which was a substantial redesign of the locomotive. [1] [2] [3]
The resultant locomotive included many proprietary boiler and ancillary fittings, as well as parts interchange ability. The firebox was substantially altered to take into account the properties of Collie coal. This included a combustion chamber, thermic syphons and arch bar tubes. [4]
The running gear was based heavily on Beyer, Peacock & Co's Standard Light Garratt, which was built for the South Australian Railways as its 400 class. The first 40 were delivered partially erected, whilst the final 20 were fully assembled prior to shipping. The last 20 had larger tenders, capable of holding an additional 2,500 litres (550 imp gal; 660 US gal). All were delivered between April 1951 and June 1952. [1] [5] [6]
The light axle load of the W class, 9.5t, gave it availability across the entire WAGR Network. Although essentially a freight engine, the W class regularly hauled The Australind from Perth to Bunbury. [4] It effectively replaced the aged O and G classes still working on lighter parts of the network.
The class had a reputation for being free steamers and strong pullers. Although they have a well-deserved reputation for their reliability, like any new class the W locos suffered some minor teething problems, including ashpan failures, and leaks in and around the foundation ring. The leaks were traced to faulty welding. The class suffered from stay failures in its early days, particularly in and around the throat plate. The first to fail was W913 in 1952. At one point, no fewer than 34 of the class were in Midland Railway Workshops or regional depots for stay repair. The problem was traced back to the thermic syphons creating significant water movement in the area, overstressing the boiler plates, as well as problems with the quality of the original stays. The syphons were progressively removed over a seven-year period, eliminating the problem. [3] [7]
Following the modification, the last of which was made in 1959, the class gave excellent service. As dieselisation of WAGR continued, the class was gradually moved to the southern parts of the network. Withdrawals commenced in 1968 with the last condemned in 1972. Most of the class was scrapped in 1971, although 19 were held in reserve at Midland Railway Workshops until 1972. [1] [3] [8] The last few remained at Midland until 1980.
Beyer, Peacock & Co built four additional engines to the same design for the Silverton Tramway Company, designated as its W class.
The light axle load of the W class along with their relative youth resulted in them being sought after by tourist operators, both in Western Australia and interstate with 15 preserved. Today they form the backbone of the Hotham Valley Railway and Pichi Richi Railway fleets with each having three operational examples. Until 2006, Hotham Valley Railway's Ws operated services on the Brookfield Rail network, but today they are confined to its own heritage line. [6] [9]
Pichi Richi Railway is a 39 kilometres narrow-gauge heritage railway in the southern Flinders Ranges of South Australia between Quorn and Port Augusta. For much of its length the line lies in the picturesque Pichi Richi Pass, where the line was completed in 1879 as work proceeded north to build a railway to the "Red Centre" of Australia – the Central Australia Railway.
Beyer, Peacock and Company was an English general engineering company and railway locomotive manufacturer with a factory in Openshaw, Manchester. Charles Beyer, Richard Peacock and Henry Robertson founded the company in 1854. The company closed its railway operations in the early 1960s. It retained its stock market listing until 1976, when it was bought and absorbed by National Chemical Industries of Saudi Arabia.
The Hotham Valley Tourist Railway is a tourist and heritage railway in the Peel region of Western Australia.
Western Australian Government Railways (WAGR) was the state owned operator of railways in the state of Western Australia between October 1890 and June 2003. Owned by the state government, it was renamed a number of times to reflect extra responsibility for tram and ferry operations that it assumed and later relinquished. Westrail was the trading name of the WAGR from September 1975 until December 2000, when the WAGR's freight division and the Westrail brand were privatised. Its freight operations were privatised in December 2000, with all remaining passenger operations transferred to the Public Transport Authority in July 2003.
The Albany Progress was an overnight passenger train operated by the Western Australian Government Railways between Perth and Albany via the Eastern and Great Southern lines from May 1961 until December 1978.
The Australian Standard Garratt (ASG) was a Garratt articulated steam locomotive designed and built in Australia during World War II for use on the 1067 mm narrow-gauge railway systems owned by the Australian states of Queensland, South Australia, Tasmania and Western Australia. After the war, ASGs operated in South Australia and at the Fyansford Cement Works railway in Victoria.
The Steamtown Peterborough Railway Preservation Society Inc. was a not-for-profit incorporated society that operated a heritage steam railway from Peterborough, South Australia, north along a section of the Peterborough to Quorn railway line, between 1977 and 2002. The society based its operations on the former South Australian Railways roundhouse at Peterborough and purpose-built sheds and yard at Peterborough West.
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 Commonwealth Railways NC class consisted of two diesel-hydraulic locomotives built by Clyde Engineering, Granville, New South Wales in 1956. The Lakewood Firewood Company, Kalgoorlie was the first owner; the Commonwealth Railways purchased them in 1965. They ceased revenue service in the early 1980s.
The Commonwealth Railways NSU class was a class of diesel-electric locomotives built in 1954 and 1955 by the Birmingham Railway Carriage and Wagon Company, England, for the Commonwealth Railways to be deployed on the narrow-gauge Central Australia Railway and North Australia Railway.
The WAGR P and Pr classes were two classes of 4-6-2 steam locomotives designed for express passenger service on the Western Australian Government Railways mainline network. The initial designs were prepared by E.S. Race and together the two classes had a total build number of thirty-five locomotives, the P and Pr classes entering service in 1924 and 1938 respectively. Both classes were used on express passenger services, greatly improving the economy and speed of long-distance passenger travel in Western Australia, the results of which were most visible on the Western Australian stage of the Trans-Australian Railway and Westland Express.
The WAGR V class was the last class of steam locomotive to enter service with the Western Australian Government Railways (WAGR). The class was part of the post war regeneration plan for the WAGR, intended for the heavy coal traffic between the Collie coal fields and Perth.
The Western Australian Government Railways (WAGR) Z class was a class consisting of three lightweight six-wheeled diesel-mechanical locomotives which were active in Western Australia from November 1953 to January 1983 and which have since been preserved.
The South Australian Railways W and Wx class was a class of 2-6-0 steam locomotives operated by the South Australian Railways. Some were used by the Commonwealth Railways in the Northern Territory and by contractors.
The WAGR Pm and Pmr classes were two classes of 4-6-2 tender engine steam locomotives operated by the Western Australian Government Railways (WAGR) between 1950 and the early 1970s.
The WAGR T class was a class of 4-4-0 steam locomotives operated by the Great Southern Railway (GSR) and later Western Australian Government Railways (WAGR).
The WAGR G class is a class of steam locomotives operated by the Western Australian Government Railways (WAGR) from 1889. The class's wheel arrangement varied; 48 were 2-6-0s and 24 were 4-6-0s.
The WAGR A class was a class of 2-6-0 steam locomotives designed by Beyer, Peacock & Co and operated by the Western Australian Government Railways (WAGR) between 1881 and 1955.
The Silverton Tramway W class was a class of 4-8-2 steam locomotives operated by the Silverton Tramway Company.
WAGR G class G233 Leschenault Lady is a preserved 2-6-0 steam locomotive, built in 1898 by James Martin & Co of Gawler, South Australia, for the Western Australian Government Railways (WAGR). It is the third oldest Australian-built steam locomotive still in operational order, after Victorian Railways Y class 112 and WAGR A class 15.
