The Western Australian Government Railways (usually abbreviated to WAGR) operated many unique steam, diesel and electric locomotive classes. Often suffering from lack of available funds the WAGR locomotive fleet often consisted of locomotives far older than their expected operational life. Only one electric locomotive was operated by the government during the WAGR years.
The first WAGR locomotives were two 1875 2-6-0 tender engines, later classified as the M class, built in England in 1875 and shipped to WA by sea. They operated on the first government railway in Geraldton, some 450 km north of Perth. [1] The opening of the Fremantle to Guildford railway in 1881 saw the use of two 0-6-0T tank engines from the British Robert Stephenson and Co, numbered Numbers 1 and 2 and later classified as the C Class in 1885. The C class engines were later given small tenders to increase fuel storage. C1 was later renamed 'Katie' and is currently preserved at the Rail Transport Museum. [2]
The contractor responsible for the construction of the Fremantle-Guildford railway, John Robb, sold his locomotive to the WA government also in 1881, and it became Number 3. Number 3 became to prototype of the WAGR A class 2-6-0 tender locomotives. [1] The A class locomotives were soon supplemented by the B class 4-6-0T tank engines which had twice the haulage capacity of the A class. During this time the WAGR had been greatly expanded over the Darling Scarp and into the large agricultural strip to the East, specifically to the centers of Chidlow, Northam and Toodyay (then Newcastle). With the beginning of WA gold rushes in 1888 the railways required massive expansion and in 1889 the WAGR received a larger version of the A class which had been used in the construction of the private Great Southern Railway in Albany, on the southern coast of Western Australia. [1] The new locomotives were a vast improvement over previous types and became the WAGR G Class, of which a total of 72 were eventually ordered, becoming the railways' most numerous type for its entire history. The G class existed in two forms - the initial 2-6-0 configuration and a later 4-6-0 type with improved running stability. The G class was immensely successful on a wide range of duties, and although phased out of mainline workings in the early 20th century, it lingered until the very end of steam in WA, with two examples still working as shunters at Bunbury in August 1972. [3]
The steep 1 in 30 gradients over the Darling Scarp presented a major problem to the early railway system, so in 1893/94 the K class 2-8-4T tank engines were introduced for traffic on this Eastern Railway. The K class was the first class of locomotives designed new for the WAGR, and some were later ordered for use in South Africa. The K class was unfortunately too heavy for branch-line operations and was so restricted to main-line services. [1] In 1896 two new classes were introduced to the WAGR, namely the N Class 4-4-4T suburban tank engines and the O Class 2-8-0T&T, so classified for the presence of tenders and boiler-side fuel-storage bunkers. The N and O classes shared a standard boiler and cylinders which gave them compatibility. The N class was primarily used on suburban passenger and shunting duties - a role which it dominated for almost two decades. [1] The O class was used initially on mainline goods services but was quickly relegated to branch line services where it served successfully. In the event further orders were placed until the class totaled fifty-six, with 10 being built locally at the Midland Railway Workshops. [3]
The R class 4-4-0s represented a radical departure from previous WAGR locomotive design. The engines featured the largest diameter wheels of any WAGR locomotive at 1.45m, which allows for higher speeds at reduced power. Given the nature of WA's railways, however, this was not beneficial and the class saw limited service in its intended role as express engines, but continued to serve in country areas (such as around Northam) for many years. [1] The class numbered 24 and was withdrawn in the mid-1920s when replaced by much larger locomotives. [3]
The onset of the 20th century saw the introduction of many new locomotives to the W.A.G.R. Notable examples included the E and F class engines of 1902 which were near identical with the exception of their wheel arrangements. An additional variant of the E class was provided as the Ec class, built in the United States. The E class was used for passenger services and was accordingly given the larger diameter driving wheels in a 4-6-0 configuration, while the F class freight locomotives had a 4-8-0 arrangement, providing extra power at the expense of speed. The D class 4-6-4T suburban tank engines were likewise introduced in 1902 and replaced the N class engines in suburban operations. All three classes, with the exception of some individual locomotives, underwent the process of superheating in 1912 to become the Es, Fs and Ds classes respectively. [1] Also in 1912 the M class garratt-type locomotives were introduced, representing the first use of this type of locomotive in full-size mainline operation. The class was well adapted to WAGR's light branchlines and tight-radius curves thanks to its articulation. [1]
Suffering from the effects of both the First World War and the Great Depression, the WAGR introduced relatively few locomotive classes in the years between World War One and World War Two. The P class 4-6-2 pacific-type locomotives were introduced in 1924 and in 1938 an improved version, the Pr Class was constructed at the Midland workshops. 8 P class engines were converted to Pr class between 1941 and 1944 to alleviate war time stresses on the aged WAGR locomotive fleet, most of which dated back to the 19th century. [4] In 1936, the company owned 420 locomotives and 4 railcars. [5]
In the years following World War Two, the WAGR underwent a massive expansion and quickly introduced new services and many new locomotive classes.
Mainline diesel locomotives arrived on the WAGR in 1953 with the introduction of the WAGR Y class and in 1954 with the X Class while diesel shunting locomotives had arrived in 1953 with the Z Class.
Under the Whyte notation for the classification of steam locomotives, 4-6-2 represents the wheel arrangement of four leading wheels on two axles, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The 4-6-2 locomotive became almost globally known as a Pacific type after a New Zealand locomotive that was shipped across the Pacific Ocean.
The Southern Railway took a key role in expanding the 660 V DC third rail electrified network begun by the London & South Western Railway. As a result of this, and its smaller operating area, its steam locomotive stock was the smallest of the 'Big Four' companies.
Beyer, Peacock and Company was an English railway locomotive manufacturer with a factory in Openshaw, Manchester. Founded by Charles Beyer, Richard Peacock and Henry Robertson, it traded from 1854 until 1966. The company exported locomotives, and machine tools to service them, throughout the world.
The Eastern Railway is the main railway route between Fremantle and Northam in Western Australia. It opened in stages between 1881 and 1893. The line continues east to Kalgoorlie as the Eastern Goldfields Railway.
Western Australian Government Railways (WAGR) was the operator of railway services 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 WAGR from September 1975 until December 2000, when the WAGR's freight division and the Westrail name and logo were privatised. Its freight operations were privatised in December 2000 with the remaining passenger operations transferred to the Public Transport Authority in July 2003.
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 WAGR D class was a class of 4-6-4T tank locomotive operated by the Western Australian Government Railways (WAGR) between 1912 and 1964.
The WAGR Dm class was a class of 4-6-4T tank locomotive operated by the Western Australian Government Railways (WAGR) between 1945 and 1971.
The WAGR Dd class was a class of 4-6-4T tank locomotive operated by the Western Australian Government Railways (WAGR) between 1946 and 1972.
The Western Australian Government Railways (WAGR) O Class was a class consisting of fifty-six 2-8-0 steam locomotives which were introduced by the WAGR between 1896 and 1912. Despite them being tender locomotives, they also featured short boiler side tanks for additional water storage. A useful feature for the long distances required by operation on Western Australia's country lines.
The WAGR N class was a class of steam locomotives operated by the Western Australian Government Railways (WAGR) from 1896 until 1960.
The WAGR C Class was a class of steam locomotives built by Robert Stephenson and Company for the Western Australian Government Railways in 1880 to the same design as the NZR F class.
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 H class was a class of two steam locomotives operated by the Western Australian Government Railways (WAGR) introduced in 1889.
The WAGR Q class was a six-member class of 4-6-2T tank engine steam locomotives operated by the Western Australian Government Railways (WAGR) between 1896 and 1925.
The WAGR B class was a class of 4-6-0T tank locomotives operated by the Western Australian Government Railways (WAGR) between 1884 and 1959.
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 WAGR D class was a single member class of 0-4-0ST tank locomotive operated by the Western Australian Government Railways (WAGR) from 1884 until 1903.
The Cape Government Railways 1st Class 4-4-0T of 1875 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.
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.
