Queensland B18¼ Class Locomotive
The Queensland Railways B18¼ class locomotive was a class of 4-6-2 steam locomotives operated by the Queensland Railways. History The first batch of 17 B18¼ class locomotive were built by the North Ipswich Railway Workshops in 1926. Per Queensland Railway's classification system they were designated the B18 class, B representing they had three driving axles, and the 18 the cylinder diameter in inches. Further orders saw the class total 83 by 1947 with some built by Walkers Limited. The latter examples were fitted with modified boilers and improved cabs. The early examples were painted prussian blue with the boilers having a natural finish. The latter examples were painted black with red lining. In 1949 all were repainted green with red lining. From 1951 they began to be relegated following the delivery of the BB18¼ class. The first was withdrawn in March 1967, with the last removed from traffic in 1970.

North Ipswich Railway Workshops
North Ipswich Railway Workshops is a heritage-listed former Australian railway workshop at North Street, North Ipswich, Queensland. It was built from 1878 to 1980s. It is also known as the Workshops Rail Museum. It was added to the Queensland Heritage Register on 21 April 1997. History Unlike other colonies, the first railway in Queensland started from a provincial town, Ipswich, instead of from the capital city, Brisbane. The rationale was that transport between Brisbane and Ipswich was already adequately serviced by the Brisbane River, and the most urgent need was to improve transport between Ipswich and the productive Darling Downs region. The construction contract was awarded to well-known British contractor Peto, Brassey and Betts. Work started in early 1864 and the first section of line was opened in 1865, gradually extending to the Darling Downs and eventually further west. The line between Ipswich and Brisbane was completed in 1875. The first workshops were also built i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walkers Limited
Walkers Limited was an Australian engineering company, based in Maryborough, Queensland. It built ships and railway locomotives. The Walkers factory still produces railway locomotives and rolling stock as part of Downer Rail. History In 1863 John Walker and three friends set up the ''Union Foundry'' of John Walker & Co in Ballarat. In 1867 a branch was opened in Maryborough. The Ballarat assets were disposed of in 1879 and in 1884, the business became a limited company under the title ''John Walker & Co Limited'', being renamed ''Walkers Limited'' in 1888. The company produced most of the parts for machinery at sugar mills. In 1980 Walkers Limited was sold to Evans Deakin Industries. It was included in the purchase of Evans Deakin by Downer Group in March 2001 and today the Maryborough factory continues to operate as part of Downer Rail. In 2003 Bundaberg Foundry Engineers completed the acquisition of the Walkers Sugar Business and moved to change the operating name t ...

4-6-2
Under the Whyte notation for the classification of steam locomotives, 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 locomotive became almost globally known as a Pacific type. Overview The introduction of the design in 1901 has been described as "a veritable milestone in locomotive progress". On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric locomotive, electric or diesel locomotive, diesel-electric locomotives during the 1950s and 1960s. Nevertheless, new Pacific designs continued to be built until the mid-1950s. The type is generally considered to be an enlargement of the 4-4-2 (locomotive), Atlantic type, although its NZR Q class (1901), prototype had ...

Walschaerts Valve Gear
The Walschaerts valve gear is a type of valve gear used to regulate the flow of steam to the pistons in steam locomotives, invented by Belgium, Belgian railway mechanical engineering, engineer Egide Walschaerts in 1844. The gear is sometimes named without the final "s", since it was incorrectly patented under that name. It was extensively used in steam locomotives from the late 19th century until the end of the steam era. History The Walschaerts valve gear was slow to gain popularity. The Stephenson valve gear remained the most commonly used valve gear on 19th-century locomotives. However, the Walschaerts valve gear had the advantage that it could be mounted entirely on the outside of the locomotives, leaving the space between the locomotive frame, frames clear and allowing easy access for service and adjustment, which resulted in it being adopted in some articulated locomotives. The first locomotive fitted with the Walschaerts valve gear was built at the Belgian Tubize worksh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queensland Rail
Queensland Rail (QR) is a railway operator in Queensland, Australia. Owned by the Queensland Government, it operates local and long-distance passenger services, as well as owning and maintaining approximately 6,600 kilometres of track and related infrastructure. QR was also responsible for all Queensland freight services, and from 2002 operated interstate services under the Australian Railroad Group, Interail and QR National brands. These were all spun out into a separate entity in July 2010, and later privatised as Aurizon. History Beginnings Queensland Railways was the first operator in the world to adopt narrow gauge (in this case ) for a main line, and this remains the systemwide gauge within Queensland today. The colony of Queensland separated from New South Wales in 1859, and the new government was keen to facilitate development and immigration. Improved transport to the fertile Darling Downs region situated west of Toowoomba was seen as a priority. As adequate river ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

List Of Queensland Steam Locomotives
Between 1864 and 1958, Queensland Railways ordered 47 types of locomotives for purposes such as freight, passenger and mail train use. Classification Until 1889, each of the isolated sections of the Queensland Railways adopted its own locomotive numbering system. With the impending joining of most of the sections, in 1890 a new centralised classification system was adopted to eliminate duplications. Locomotives on the Southern & Western Railway retained their existing numbers, with locomotives on other networks renumbered where there was a duplication. The classification system consisted of a letter, indicating the number of driving axles, followed by a number, indicating the cylinder diameter in inches and factions of inches. This was confusing for two reasons: *it differed from the international system *it could lead to several classes having the same classification number Where classification numbers were duplicated, the classes were usually distinguished by the name of the ...

Driving Wheel
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. On diesel and electric locomotives, the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft drive and coupling rods were used in the past (e.g. in the Swiss Crocodile locomotive) but their use is now confined to shunting locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets which are linked together within the set. Diameter Driving wheels ...

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber.

Queensland BB18¼ Class Locomotive
The Queensland Railways BB18¼ class locomotive was a class of 4-6-2 steam locomotives operated by the Queensland Railways. History The first 35 BB18¼ class locomotives were built by the Vulcan Foundry in Newton-le-Willows, England in 1950/51. Per Queensland Railway's classification system they were designated the BB18¼ class, BB representing they had three driving axles, and the 18¼ the cylinder diameter in inches. A further 20 built by Walkers Limited, Maryborough between 1955 and 1958. No. 1089 was the last steam engine placed into service on a mainline Australian railway. Their route availability was always the same as for the BB18¼ and C19. The extremities of that availability when they were introduced were (from Brisbane) Roma, Wallan-garra, Merinda (near Bowen), plus branches Bundamba to 3 miles 8 chains (on loop to Redbank), Gowrie to Wyreema loop, Warwick to Thane (South-Western Line), Ipswich to Workshops Gate, South Brisbane to Lota, Kuraby and Corinda, Sho ...

Railway Locomotives Introduced In 1926
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...
