520 Class Steam Locomotive
The South Australian Railways 520 class is a class of 4-8-4 steam locomotives operated by the former South Australian Railways. Need During the war years in the early 1940s, the South Australian Railways (SAR) had a desperate need for additional tractive power on increasingly growing troop and supply trains and with the combined need for quick acceleration and high speed running on the flat and generally straight mainlines to the north of Adelaide to Port Pirie, as well as power "under the belt" for the long , 1-in-45 (2.2%) graded slog up the Adelaide Hills to Melbourne, a new locomotive design was required by the SAR. With this in mind, the 520 class was commissioned, combining the better features of the earlier 500 and 620 class locomotives. Design The class used the 4-8-4 configuration of the modified 500B class, but was also designed for work on branch lines with light rail with a reduced tender load. The considerable weight of the locomotive was spread over eight axles, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Playford IV
Sir Thomas Playford (5 July 1896 – 16 June 1981) was an Australian politician from the state of South Australia. He served continuously as Premier of South Australia and leader of the Liberal and Country League (LCL) from 5 November 1938 to 10 March 1965. Though controversial, it was the longest term of any elected government leader in Australian history. His tenure as premier was marked by a period of population and economic growth unmatched by any other Australian state. He was known for his parochial style in pushing South Australia's interests, and was known for his ability to secure a disproportionate share of federal funding for the state as well as his shameless haranguing of federal leaders. His string of election wins was enabled by a system of malapportionment and gerrymander later dubbed the "Playmander". Born into the Playford family, an old political family, he was the fifth Thomas Playford and the fourth to have lived in South Australia; his grandfather Thomas Pla ...

Pennsylvania Railroad
The Pennsylvania Railroad (reporting mark PRR), legal name The Pennsylvania Railroad Company also known as the "Pennsy", was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. It was named for the commonwealth in which it was established. By 1882, Pennsylvania Railroad had become the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Its budget was second only to the U.S. government. Over the years, it acquired, merged with, or owned part of at least 800 other rail lines and companies. At the end of 1926, it operated of rail line;This mileage includes companies independently operated. PRR miles of all tracks, which includes first (or main), second, third, fourth, and sidings, totalled 28,040.49 at the end of 1926. in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific and Atchison, T ...

Balhannah
Balhannah is a town in the Adelaide Hills about 30 km southeast of Adelaide, the capital of South Australia. It was established in 1839 as a farming community by James Turnbull Thomson, who built the first hotel. The town soon grew to incorporate two once adjoining towns: Gilleston (named for Osmond Gilles) and Blythetown, named for James Blythe, another Scottish settler. It is on the main interstate railway between Adelaide and Melbourne. In the past it was the junction for a branch line that ran up the Onkaparinga Valley and beyond to Birdwood and Mount Pleasant. Much of Balhannah is along Onkaparinga Valley Road, although there are some other residential streets, and Greenhill Road terminates near the town centre. One of the larger businesses in the town is a long-established hardware store, now part of the Mitre 10 Mitre 10 is an Australian retail and trade hardware store chain. Operations are based on a cooperative system, where the store owners are member ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Railway Historical Society
The Australian Railway Historical Society (ARHS) aims to foster an interest in the railways, and record and preserve many facets of railway operations. It had divisions in every state and the Australian Capital Territory, although the ACT division was wound up in 2016, along with the Victorian division in 2020. Since 1967, when each division incorporated, the state divisions have operated as separate entities. Each still trades under the ARHS brand, except in Western Australia, where the division is called Rail Heritage WA. Individual membership exceeds 2,500. Background The ARHS was founded in Sydney in 1933 as The Railway Circle, becoming the Australasian Railway and Locomotive Historical Society shortly afterwards. The society's name was changed to the present form in 1952. Divisions were later formed in most states, most of which established a railway museum, namely: *ACT - Canberra Railway Museum, Kingston *Queensland - Rosewood Railway Museum *South Australia - SteamRang ...

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 ...

SteamRanger
The SteamRanger Heritage Railway is a long broad gauge tourist railway, formerly the Victor Harbor railway line of the South Australian Railways (SAR). It is operated by the not-for-profit South Australian Division of the Australian Railway Historical Society. As the last operating non-suburban line of the former broad-gauge network, on which Australia's first public railway was opened, the line and its associated rail assets have high historical significance. History In the 1970s, the South Australian Division of the Australian Railway Historical Society established SteamRanger as a not-for-profit railway preservation offshoot to operate its train tours from Adelaide, mainly on rural lines throughout the state's broad gauge networks. SteamRanger opened their first purpose-built depot at Dry Creek railway station, north of Adelaide in 1980. From the mid-1980's, SteamRanger gradually took over the operation & maintenance of the Victor Harbor railway line. When plans were an ...

South Australian Railways Loco 526 On Port Pirie Line Near Mallala, August 1970
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

Blowback (steam Engine)
A blowback (also blow back or blow-back) is a failure of a steam locomotive, which can be catastrophic. One type of blowback is caused when atmospheric air blows down the locomotive's chimney, causing the flow of hot gases through the boiler tubes to be reversed, with the fire itself being blown through the firehole onto the footplate, with potentially serious consequences for the crew. The risk of backdraught is higher when the locomotive enters a tunnel because of the pressure shock. Such blowbacks can be prevented by opening the blower before closing the regulator. Similar blowback can be caused by debris or other obstructions in the smokebox. In the days when steam-hauled trains were common in the United Kingdom, blowbacks occurred fairly frequently. In a 1955 report on an accident near Dunstable, the Inspector wrote: He also recommended that the British Transport Commission carry out an investigation into the causes of blowbacks. Blowbacks can also occur when a steam tub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

South Australian Railways 830 Class
The 830 class are a class of diesel locomotives built by AE Goodwin, Auburn for the South Australian Railways between 1959 and 1966. The New South Wales 48 class and Silverton Rail 48s class are of a very similar design. History In 1959, the South Australian Railways placed an order for 10 Alco DL531 locomotives for use in light freight haulage, especially on branch lines where a low axle load was essential. Further orders saw the fleet built up to 44 by February 1970 with 15 narrow gauge, 12 standard gauge and 17 broad gauge examples. In February 1970, an additional unit was purchased second hand from Silverton Tramway. In March 1978, 43 were included in the transfer of the South Australian Railways to Australian National with the other two (no. 830 & 845) going to the State Transport Authority before also moving to Australian National. From July 1974 until December 1980 847–849, were loaned to the Public Transport Commission where they were pooled with the 48 class. ...

Indicated Horsepower
Horsepower (hp) is a unit of measurement of Power (physics), power, or the rate at which Work (physics), work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish people, Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the International System of Units, SI unit watt for measurement of power. With the implementation of the EU Directive Units of Measure Directive#Directive 80/181/EEC, 80/181/EEC on 1 J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roller Bearing
In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding. One of the earliest and best-known rolling-element bearings are sets of logs laid on the ground with a large stone block on top. As the stone is pulled, the logs roll along the ground with little sliding friction. As each log comes out the back, it is moved to the front where the block then rolls on to it. It is possible to imitate such a bearing by placing several pens or pencils on a table and placing an item on top of them. See " bearings" for more on the historical development of bearings. A rolling element rotary bearing uses a shaft in a much larger hole, and cylinders called "rollers" tightly fill the space between t ...
