Staines Railway Bridge
Staines Railway Bridge is a railway viaduct in Staines-upon-Thames, Surrey, around west of central London. It carries the Waterloo to Reading line across the Thames. Immediately to the east is Thames Street bridge, which carries the railway over the B376 and the Thames Path. History An act of parliament was granted in 1853, authorising the Staines, Wokingham and Woking railway (SWWR) to build a line between Staines and Wokingham railway stations. Construction of the Staines Railway Bridge, across the River Thames, was completed in 1856. The SWWR merged with the London and South Western Railway in 1878. The line across the viaduct was electrified in 1937. Staines Railway Bridge was designed by John Gardner and cost £10,000 to build. It is constructed of wrought iron girders supported on six cast iron pillars, embedded in the river bed. The main span is wide and the total length of the bridge is . It is upstream of London Bridge. During the Second World War, the line was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterloo–Reading Line
The Waterloo–Reading line is a National Rail electric railway line between London Waterloo and Reading. The line runs west through a series of South West London suburbs to Reading, in central Berkshire. Its passenger operation is by South Western Railway (SWR), which also manage its stations. The Waterloo–Reading line is the core of a group of lines and branches heading generally westwards from Waterloo, providing predominantly passenger services into London. All of the branches and connecting lines have direct services into a dedicated group of platforms at Waterloo, so most of the services using the line do not run the whole length of the line. After leaving Waterloo, the line runs parallel to the South West Main Line before diverging at Clapham Junction and heading westwards. Within Greater London, the Hounslow Loop Line diverges at Barnes and reconnects again near Feltham, whilst the Kingston Loop Line diverges at Twickenham to join up with the South West Main Line a ...

Cast Iron
Cast iron is a class of iron– carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applicatio ...

Railway Bridges In Surrey
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges Across The River Thames
The River Thames is the second-longest river in the United Kingdom, passes through the capital city, and has many crossings. Counting every channel – such as by its islands linked to only one bank – it is crossed by over 300 bridges. If taking cuts – excavated channels – to be measurements of river, its course west of Tilbury, traversing has 27 tunnels, six public ferries, one cable car link, and one ford. From end to end a channel of the Thames can be seen, mostly its main flow, which is passed over by 138 bridges. These are listed here with 2 former bridges and a seasonal festival bridge. Over 162 other bridges link to such places as typical or man-made islands or across an array of corollary and lesser side channels (backwaters), particularly in and around Oxford and the non-village channel of Ashton Keynes — these are not listed. The river's lower estuary is shallow – but wide – and has no crossing east of Tilbury, the ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staines Bridge
Staines Bridge is a road bridge running in a south-west to north-east direction across the River Thames in Surrey. It is on the modern A308 road and links the boroughs of Spelthorne and Runnymede at Staines-upon-Thames and Egham Hythe. The bridge is Grade II listed. The bridge crosses the Thames on the reach between Penton Hook Lock and Bell Weir Lock, and is close to and upstream of the main mouth of the River Colne, a tributary. The bridge carries the Thames Path across the river. Its forebear built in Roman Britain, the bridge has been bypassed by three arterial routes, firstly in 1961 by the Runnymede Bridge near Wraysbury and in the 1970s by the building of the UK motorway network (specifically near Maidenhead and Chertsey). Owing to the commercial centres of the town in Spelthorne and of Egham, the bridge has had peak hour queues since at least the 1930s. History In Roman times, Staines lay on the Devil's Highway, an important road connecting the provincial capita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platoon

HMNB Portsmouth
His Majesty's Naval Base, Portsmouth (HMNB Portsmouth) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Devonport). Portsmouth Naval Base is part of the city of Portsmouth; it is located on the eastern shore of Portsmouth Harbour, north of the Solent and the Isle of Wight. Until the early 1970s, it was officially known as Portsmouth Royal Dockyard (or HM Dockyard, Portsmouth); thereafter the term 'Naval Base' gained currency, acknowledging a greater focus on personnel and support elements alongside the traditional emphasis on building, repairing and maintaining ships. In 1984 Portsmouth's Royal Dockyard function was downgraded and it was formally renamed the 'Fleet Maintenance and Repair Organisation' (FMRO). The FMRO was privatized in 1998, and for a time (from 2002 to 2014), shipbuilding, in the form of block construction, returned. Around 2000, the designation HMS ''Nelson'' (which until then had been specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Bridge
Several bridges named London Bridge have spanned the River Thames between the City of London and Southwark, in central London. The current crossing, which opened to traffic in 1973, is a box girder bridge built from concrete and steel. It replaced a 19th-century stone-arched bridge, which in turn superseded a 600-year-old stone-built medieval structure. This was preceded by a succession of timber bridges, the first of which was built by the Roman Empire, Roman founders of London. The current bridge stands at the western end of the Pool of London and is positioned upstream from previous alignments. The approaches to the medieval bridge were marked by the church of St Magnus-the-Martyr on the northern bank and by Southwark Cathedral on the southern shore. Until Putney Bridge opened in 1729, London Bridge was the only road crossing of the Thames downstream of Kingston upon Thames. London Bridge has been depicted in its several forms, in art, literature, and songs, including the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardenable by heating and quenching. Wrought iron is highly refined, with a small amount of silic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Thames
The River Thames ( ), known alternatively in parts as the River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire, and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west it flows through Oxford (where it is sometimes called the Isis), Reading, Henley-on-Thames and Windsor. The Thames also drains the whole of Greater London. In August 2022, the source of the river moved five miles to beyond Somerford Keynes due to the heatwave in July 2022. The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of . From Oxford to the Estuary the Thames drops by 55 metres. Running through some of the drier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Electrification In Great Britain
Railway electrification in Great Britain began in the late 19th century. A range of voltages has been used, employing both overhead lines and conductor rails. The two most common systems are using overhead lines, and the third rail system used in Southeast England and on Merseyrail. As of March 2020, (38%) of the British rail network was electrified. According to Network Rail, as at 2003, 64% of the electrified network used the 25kVAC overhead system, and 36% used the 660/750VDC third-rail system.Network Rail, 2003 Technical Plan, Chapter 11 "Network Capability", page 7 "Electrification". "Approximately 40% of the rail network is currently equipped with electrification." From page 1, total network is 30764 km, 7587 km of 25 kV AC, 4285 km of 650/750 V DC and 28 km of 1500 V DC. Excludes CTRL, LUL, Old Danby test track, bulk of Tyne and Wear Metro, etc. NB it does not state what method of counting length of network is used - i.e. sidings, loops, double track etc. produce d ...
