Jamestown Viaduct
The Jamestown Viaduct is part of the northern approach to the Forth Bridge in Scotland. It crosses the hamlet of Jamestown and the village of North Queensferry in Fife. History It was constructed between 1887 and 1890, and listed as a Grade B listed building in 2004. In 2005, the viaduct was strengthened during an eight-day closure of the railway. of steel and of high strength concrete were used to add a reinforced concrete slab underneath the track, in order to improve the load-carrying capacity to Network Rail's standards. The work was worth around , and engineered by Corus and carried out by Mowlem. 20,000 man-hours were worked during the period of closure, which coincided with a "possession" of the Forth Bridge. Design It has four main steel girder spans, supported by three sandstone piers. As well as the four steel spans, there is a stone arch at each end of the viaduct. The steel spans are long, and are at a skew of 70° The spans consist of twin truss gird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LNER Class K4
The London and North Eastern Railway (LNER) Class K4 is a class of 2-6-0 steam locomotives designed by Nigel Gresley for the steep grades of the West Highland Line. West Highland Line challenge The North British Railway (NBR) West Highland line to Mallaig via Fort William, presented a combined triple operating challenge of: steep gradients; severe curves; and restrictive axle loading limits. Having used D34 'Glen' 4-4-0s, increased loads led to regular double-heading. Locomotive engineers proposed use of LNER Class K3, but they would not have been permitted to operate between Fort William and Mallaig. Having proposed a new design based on a K3 boiler, in October 1924 a loan was made of a single LNER Class K2, which provided the required increase in power and adhesion. As K3s replaced K2 on the network, more K2s were loaned to the line, with the loan becoming permanent from October 1925. With further increases in load and needs for additional traffic speed, in Septembe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges In Fife
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Bridges In Scotland
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 ...

Viaducts In Scotland
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A90 Road
The A90 road is a major north to south road in eastern Scotland, running from Edinburgh to Fraserburgh, through Dundee and Aberdeen. Along with the A9 and the A82 it is one of the three major north–south trunk roads connecting the Central Belt to the North. Background The creation and development of the A90 road has to be understood in terms of the development of the economy of the North-East of Scotland which had resulted in an increase in traffic along the route between Perth and Aberdeen. In recognition of this, in 1979, the British government announced that it was giving priority to the upgrading of the route to dual carriageway standard. It had already been decided that the trunk route between Dundee and Stonehaven which, previously, had followed the same route as the railway line between the two towns, would now follow an inland route through Forfar and Laurencekirk. The new route would incorporate the A85 from Perth to Dundee the A929 between Dundee and Forfar, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longannet Power Station
Longannet power station was a large coal-fired power station in Fife, and the last coal-fired power station in Scotland. It was capable of co-firing biomass, natural gas and sludge. The station stood on the north bank of the Firth of Forth, near Kincardine on Forth. Its generating capacity of 2,400 megawatts was the highest of any power station in Scotland. The station began generating electricity in 1970, and when it became fully operational it was the largest coal-fired station in Europe. At the time of closure it was the third largest, after Bełchatów in Poland and Drax in England, and the 21st most polluting. Longannet was operated by the South of Scotland Electricity Board until 1990, when its operation was handed over to Scottish Power following privatisation. After failing to win a contract from National Grid, the station closed on 24 March 2016. The station was a regional landmark, dominating the Forth skyline with its chimney stack. Longannet lacked cooling tow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
