Commonwealth Railways G Class
The Commonwealth Railways G class was a class of twenty-six tender locomotives of the Commonwealth Railways, Australia. The class operated between Port Augusta (later, Port Pirie Junction railway station, Port Pirie) and Kalgoorlie on the Trans-Australian Railway. History The Commonwealth Railways was only inaugurated in 1911, so when in 1912 the railway planned to acquire its first locomotives, the decision was to adopt a design of proven reliability from another Australian railway system. The New South Wales Government Railways had the advantage of being the only other standard-gauge railway on the continent, and its 191-strong fleet of New South Wales C32 class locomotive, P class (later named C32 class) locomotives had been refined since their introduction 20 years earlier. In December 1912, companies were Invitation to tender, invited to quote for four locomotives based on the P class but with much larger Tender (rail), tenders because of the long distances be ...

National Railway Museum, Port Adelaide
Australia's National Railway Museum is the largest railway museum in Australia. More than 100 major exhibits, mainly from the South Australian Railways (SAR) and Commonwealth Railways and their successor, Australian National Railways Commission, Australian National, are on display at its site in Port Adelaide, South Australia. The museum opened at Lipson Street in 1988 after 18 years at the SAR's former main locomotive depot at Mile End, South Australia, Mile End. History Mile End, 1964–1988 In 1963, a group of rail preservationists asked the South Australian Railways Commissioner to allocate land on the site of the former Mile End, South Australia, Mile End roundhouse to hold a small collection of withdrawn steam locomotives. The first locomotive arrived in 1964 and in 1970 the site opened as the Mile End Railway Museum. Only a few exhibits were under cover and the effects of weather took their toll; an alternative, under-cover venue was sought. Move to Port Adelaide In ...

Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

Commonwealth Railways GM Class
The GM class are a class of diesel locomotives built by Clyde Engineering, Granville for the Commonwealth Railways in several batches between 1951 and 1967. As at January 2014, some remain in service with Aurizon and Southern Shorthaul Railroad. History The design was based on the Electro-Motive Diesel EMD F7 locomotive. The first 11 were delivered with EMD 16-567B, engines and four powered axles with the remainder having 16-567C, engines and six powered axles. The final 11 were fitted with dynamic braking. Delivered to operate on the standard gauge Trans-Australian Railway, the first entered service in September 1951. Further orders saw 47 in service by December 1967. They operated on all of Commonwealth Railways's standard gauge lines including those to Broken Hill, Alice Springs, Marree and Adelaide when converted to standard gauge in 1970, 1980 and 1982 respectively. In January 1972, three (31, 32 & 34) were loaned to the Victorian Railways for use on the North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonwealth Railways C Class
The Commonwealth Railways C class was a class of passenger locomotives built in 1938 by Walkers Limited, Maryborough, for the Commonwealth Railways, Australia. History Following the extension of Commonwealth Railways' standard gauge line from Port Augusta to Port Pirie in 1937, and with increasing loads being hauled on the Trans-Australian Railway, an order was placed with Walkers Limited, Maryborough for eight 4-6-0 passenger locomotives to the same design as the New South Wales Government Railways' C36 class, but with higher capacity tenders. Chris's Commonwealth Railways Pages All were delivered between January and April 1938. The new locomotives were able to shave 10 hours off the journey time of the '' |
Steam
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. ...

Superheater
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres). Types * A radiant superheater is placed directly in radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. * A convection superheater is located in the convective zone of the furnace usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters. * A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system. This superheater design incorporates additional burners in the area of superheater pipes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trans-Australian
The ''Trans-Australian'' (originally known as the ''Trans-Australian Express'') was an Australian passenger train operated by the Commonwealth Railways initially between Port Augusta and Kalgoorlie on the Trans-Australian Railway line, and later extended west to Perth, and east to Port Pirie and Adelaide. History The train commenced operating between Port Augusta and Kalgoorlie in 1917 following the completion of the Trans-Australian Railway.Trans-Australian Passenger Train comrail.com It was extended to in 1937 following the conversion of this line to standard gauge.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Ballast
Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it. A variety of materials have been used as track ballast, including crushed stone, washed gravel, bank run (unwashed) gravel, torpedo gravel (a mixture of coarse sand and small gravel), slag, chats, coal cinders, sand, and burnt clay. The term "ballast" comes from a nautical term for the stones used to stabilize a ship. Construction The appropriate thickness of a layer of track ballast depends on the size and spacing of the ties, the amount of traffic on the line, and various other factors. Track ballast should never be laid down less than thick, and high-speed railway lines may require ballast up to thick.Bell 2004, p. 39 ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
