New South Wales AD60 Class Locomotive
The 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 and Company for the New South Wales Government Railways in Australia. Design The AD60 Class 4-8-4+4-8-4 Beyer-Garratt patent consists of a boiler carried on a separate frame in the centre of the locomotive and supported by the frames of the two engines, one at each end. The locomotive thus consists of three parts: a front engine unit carrying a water tank, an intermediate chassis pivoted to each engine unit supporting a boiler and cab, and a rear engine unit carrying a coal bunker and water tank. The standard gauge coupled axle loading of and able to negotiate curves. The design incorporated the most modern technology to minimise maintenance and repairs, including: *integral cast steel engine bed frames incorporating the cylinders *large steel boiler with roundtop firebox and flexible stays *mec ...

Cowan Bank
Cowan Bank is an double-track section of the standard gauge Main North line in New South Wales, Australia. It starts at Cowan station, north of Sydney, descending from to sea level at Hawkesbury River station. It has an average grade of 2.5% (1 in 40). Overview Cowan Bank has five tunnels (of which four are still in use), one level crossing (for track work road vehicles only) situated between Boronia #2 and #3 tunnels, and two road bridges. The line crosses under the Pacific Highway twice, once using a road bridge near Cowan station and again while passing through Boronia #1 tunnel. It crosses under the Sydney-Newcastle Freeway while passing through Boronia #2 tunnel. The line was built through very rugged and heavily forested terrain on the western edge of the Ku-ring-gai Chase National Park. Because of its isolated location there are very few places from where the track can be observed - sections of the Pacific Highway on the ridge between Cowan and the Hawkesbury Rive ...

Mechanical Stoker
A mechanical stoker is a mechanical system that feeds solid fuel like coal, coke or anthracite into the furnace of a steam boiler. They are common on steam locomotives after 1900 and are also used on ships and power stations. Known now as a spreader stoker they remain in use today especially in furnaces fueled by wood pellets or refuse. There are three types: the over feed, the under feed and the cross feed. The over feed delivers coal on to the top of the coals already in the furnace in the manner of a human working a shovel. The under feeder pushes fresh coal into the bottom of the furnace and then advances it upwards so that it mixes with the burning coal above. The mechanical means used are, depending on design, combinations of the screw feed, the conveyor belt, the bucket chain, the paddle and the ram. Steam jets from the boiler or a mechanical catapult may also be used to throw coal into the far reaches of the furnace. Use in steam locomotives The confined working c ...

Detonator (railway)
A railway detonator (torpedo in North America) is a coin-sized device that is used as a loud warning signal to train drivers. It is placed on the top of the rail, usually secured with two lead straps, one on each side. When the wheel of the train passes over, it explodes, emitting a loud bang. It was invented in 1841 by English inventor Edward Alfred Cowper. Uses Typical uses of detonators include: * A warning, caution or stop signal in dense fog, when signals are difficult to see * A warning of a train stopped on the line ahead by an incident or accident—the train crew are usually responsible for placing the detonators * A warning of ongoing engineering works ahead * When a signaller or other railway employee requires to stop approaching trains in an emergency On a high-speed line, detonators may need to be placed on both rails. As with all explosives, detonators can become unstable over time and must, therefore, be replaced regularly. They are triggered by pressure, r ...

Goulburn, New South Wales
Goulburn ( ) is a regional city in the Southern Tablelands of the Australian state of New South Wales, approximately south-west of Sydney, and north-east of Canberra. It was proclaimed as Australia's first inland city through letters patent by Queen Victoria in 1863. Goulburn had a population of 23,835 at June 2018. Goulburn is the seat of Goulburn Mulwaree Council. Goulburn is a railhead on the Main Southern line, a service centre for the surrounding pastoral industry, and also stopover for those traveling on the Hume Highway. It has a central park and many historic buildings. It is also home to the monument the Big Merino, a sculpture that is the world's largest concrete-constructed sheep. History Goulburn was named by surveyor James Meehan after Henry Goulburn, Under-Secretary for War and the Colonies, and the name was ratified by Governor Lachlan Macquarie. The colonial government made land grants to free settlers such as Hamilton Hume in the Goulburn area from the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enfield, New South Wales
Enfield is a suburb in the Inner West of Sydney, in the state of New South Wales, Australia. It is 11 kilometres south-west of the Sydney central business district in the Local government in Australia, local government area of Municipality of Burwood. History The suburb is named after Enfield Town, a suburb of London, England. Aboriginal culture Before the arrival of the First Fleet in 1788, the Enfield area belonged to the Wangal people, a clan of the Eora tribe, which covered most of Sydney. In the early years, the Eora people were badly affected by smallpox, which arrived with the British. Many of the clans became unsustainably small and the survivors formed new bands who lived where they could. While it would be wrong to say that the local indigenous population gave no resistance to British land claims (Pemulwuy being a notable example), within thirty years or so of the colony's establishment, most of the land in the inner-west had been conceded to British settlers.

New South Wales D57 Class Locomotive
The D57 class was a class of 4-8-2 steam locomotives built by Clyde Engineering for the New South Wales Government Railways in Australia. The tenders were built by Mort's Dock. Introduction The locomotives were among the heaviest of locomotives in Australia with a axle load and this along with their width restricted their sphere of operation to Thirroul on the Illawarra line, Wallerawang on the Main Western line and Junee on the Main South line. Due to the immense size of the firebox, they could not be hand fired and had to use a mechanical stoker, thus becoming the first New South Wales locomotive class to use a mechanical stoker. They were later followed by the 58 class and the 60 class They were not permitted to operate on the Main Northern line due to load limitations on some bridges and a tighter loading gauge. They had the highest tractive effort of any conventional engines used in Australia and were of approximately equal capability to the modified 60 class Garratt ...

South African Railways
Transnet Freight Rail is a South African rail transport company, formerly known as Spoornet. It was part of the South African Railways and Harbours Administration, a state-controlled organisation that employed hundreds of thousands of people for decades from the first half of the 20th century and was widely referred to by the initials SAR&H (SAS&H in Afrikaans). Customer complaints about serious problems with Transnet Freight Rail's service were reported in 2010. Its head office is in Inyanda House in Parktown, Johannesburg. History Railways were first developed in the area surrounding Cape Town and later in Durban around the 1840s. The first line opened in Durban on 27 June 1850. The initial network was created to serve the agricultural production area between Cape Town and Wellington. The news that there were gold deposits in the Transvaal Republic moved the Cape Colony Government (supported by British Government) to link Kimberley as soon as possible by rail to Cape Town ...

Frame (locomotive)
A locomotive frame is the structure that forms the backbone of the railway locomotive, giving it strength and supporting the superstructure elements such as a cab, boiler or bodywork. The vast majority of locomotives have had a frame structure of some kind. The frame may in turn be supported by axles directly attached to it, or it may be mounted on bogies ( UK) / trucks ( US), or a combination of the two. The bogies in turn will have frames of their own. Types of frame 250px, Preserved GWR 9017 showing outside frames Three main types of frame on steam locomotives may be distinguished:, p 255. Plate frames These used steel plates about thick. They were mainly used in Britain and continental Europe. On most locomotives, the frames would be situated within the driving wheels ("inside frames"), but some classes of an early steam locomotive and diesel shunters were constructed with "outside frames". Some early designs were double framed where the frame consisted of plates both in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garratt
A Garratt (often referred to as a Beyer Garratt) is a type of steam locomotive invented by British engineer Herbert William Garratt that is articulated into three parts. Its boiler, firebox, and cab are mounted on a centre frame or "bridge". The two other parts, one at each end, have a pivot to support the central frame; they consist of a steam engine unit – with driving wheels, trailing wheels, valve gear, and cylinders, and above it, fuel and/or water storage. Articulation permits locomotives to negotiate curves that might restrict large rigid-framed locomotives. The design also provides more driving wheels per unit of locomotive weight, permitting operation on lightly engineered track. Garratt locomotives produced as much as twice the power output of the largest conventional locomotives of railways that introduced them, reducing the need for multiple locomotives and crews. Advantages of the Garratt concept The principal benefit of the Garratt design is that the boil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reversing Gear
On a steam locomotive, the reversing gear is used to control the direction of travel of the locomotive. It also adjusts the cutoff of the steam locomotive. Reversing lever This is the most common form of reverser. It consists of a long lever mounted, parallel to the direction of travel, on the driver’s side of the cab. It has a handle and sprung trigger at the top and is pivoted at the bottom so as to pass between two notched sector plates. The reversing rod, which connects to the valve gear, is attached to this lever, either above or below the pivot, in such a position as to give good leverage. A square pin is arranged so as to engage with the notches in the plates and hold the lever in the desired position when the trigger is released. The advantages of this design are that change between forward and reverse gear can be made very quickly as is needed in, for example, a shunting engine. Disadvantages are that, because the lever must rest at one of the notches, fine adjustment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crankpin
A crankpin or crank pin, also known as a rod bearing journal, is a mechanical device in an engine which connects the crankshaft to the connecting rod for each cylinder. It has a cylindrical surface, to allow the crankpin to rotate relative to the "big end" of the connecting rod. The most common configuration is for a crankpin to serve one cylinder. However, many V engines have each crankpin shared by each pair of cylinders. Design The crankpin connects to the larger end of the connecting rod for each cylinder. This end of the connecting rod is called the "big end", as opposed to the "small end" or "little end" (which connects to the wrist/gudgeon pin in the piston). The bearing which allows the crankpin to rotate around its shaft is called the "rod bearing". In automotive engines, the most common type of rod bearing is the plain bearing, however Bushing (bearing), bushings or roller bearings are also used in some engines. Configurations In a single-cylinder engine, strai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
