Railroad Rail
Railway track ( and UIC terminology) or railroad track (), also known as permanent way () or "P way" ( and Indian English), is the structure on a railway or railroad consisting of the rails, fasteners, sleepers (railroad ties in American English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable, low-friction surface on which steel wheels can roll. Early tracks were constructed with wooden or cast-iron rails, and wooden or stone sleepers. Since the 1870s, rails have almost universally been made from steel. Historical development The first railway in Britain was the Wollaton wagonway, built in 1603 between Wollaton and Strelley in Nottinghamshire. It used wooden rails and was the first of about 50 wooden-railed tramways built over the subsequent 164 years. These early wooden tramways typically used rails of oak or beech, attached to wooden sleepers with iron or wooden nails. Gravel or small stones were packed ...

Baulk Road
Baulk road is the name given to a type of railway track or 'rail road' that is formed using rails carried on continuous timber bearings, as opposed to the more familiar 'cross-sleeper' track that uses closely spaced sleepers or ties to give intermittent support to stronger rails. Baulk road was popularised by Isambard Kingdom Brunel for his broad gauge railways in the UK, but has also been used for other railways and can still be found in modified form in special locations on present day railways. Development Brunel sought an improved design for the railway track needed for the Great Western Railway (GWR), authorised by act of parliament in 1835 to link London and Bristol. He refused to accept received wisdom without challenge. The gauge that had been adopted by most railways at that time had been fine for small mineral trucks on a horse-drawn tramway, but he wanted something more stable for his high-speed railway. The large diameter wheels used in stage coaches gave bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diagram Of Section Of Ladder Track Type Of Sleeper On Leeds And Selby Railway
A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since prehistoric times on walls of caves, but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization which is then projected onto a two-dimensional surface. The word ''graph'' is sometimes used as a synonym for diagram. Overview The term "diagram" in its commonly used sense can have a general or specific meaning: * ''visual information device'' : Like the term "illustration", "diagram" is used as a collective term standing for the whole class of technical genres, including graphs, technical drawings and tables. * ''specific kind of visual display'' : This is the genre that shows qualitative data with shapes that are connected by lines, arrows, or other visual links. In science the term is used in both ways. For example, Anderson (1997) stated more generally: "diagrams are pictorial, yet abstract, represent ...

Rubber-tyred Metro
A rubber-tyred metro or rubber-tired metro is a form of rapid transit system that uses a mix of road transport, road and rail transport, rail technology. The vehicles have wheels with rubber tires that run on a roll way inside guide bars for traction. Traditional, Flange, flanged steel wheels running on rail tracks provide guidance through Railroad switch, switches and act as backup if tyres fail. Most rubber-tyred trains are purpose-built and designed for the system on which they operate. Guided buses are sometimes referred to as 'trams on tyres', and compared to rubber-tyred metros. History The first idea for rubber-tyred railway vehicles was the work of Scotsman Robert William Thomson, the original inventor of the pneumatic tire, tyre. In his patent of 1846 he describes his 'Aerial Wheels' as being equally suitable for, "the ground or rail or track on which they run". The patent also included a drawing of such a railway, with the weight carried by pneumatic main wheels runnin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapid Transit
Rapid transit or mass rapid transit (MRT) or heavy rail, commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separation, grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as el trains – short for "elevated" – or skytrains. Rapid transit systems are usually electric railway, electric railways, that unlike buses or trams operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles. Modern services on rapid transit systems are provided on designated lines between metro station, stations typically using electric multiple units on railway tracks. Some systems use rubber-tyred metro, guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typica ...

Track Geometry
Track geometry is concerned with the properties and relations of points, lines, curves, and surfaces in the three-dimensional positioning of railroad Track (rail transport), track. The term is also applied to measurements used in design, construction and maintenance of track. Track geometry involves standards, speed limits and other regulations in the areas of track gauge, alignment, elevation, curvature and track surface. Standards are usually separately expressed for Horizontal plane, horizontal and Vertical direction, vertical layouts although track geometry is three-dimensional. Layout Horizontal layout Horizontal layout is the track layout on the horizontal plane. This can be thought of as the Multiview orthographic projection#Plan, plan view which is a view of a 3-dimensional track from the position above the track. In track geometry, the horizontal layout involves the layout of three main track types: ''tangent track'' (straight line), ''curved track'', and ''track transit ...

Feste Fahrbahn FFBögl
Feste is a fictional character in William Shakespeare's comedy ''Twelfth Night''. He is a fool (royal jester) attached to the household of the Countess Olivia. He has apparently been there for some time, as he was a "fool that the Lady Olivia's father took much delight in" (2.4). Although Olivia's father has died within the last year, it is possible that Feste approaches or has reached middle age, though he still has the wit to carry off good 'fooling' when he needs to, and the voice to sing lustily or mournfully as the occasion demands. He is referred to by name only once during the play, in answer to an inquiry by Orsino of who sang a song that he heard the previous evening. Curio responds "Feste, the jester, my lord; a fool that the lady Olivia's father took much delight in. He is about the house" (2.4). Throughout the rest of the play, he is addressed only as "Fool," while in the stage directions he is mentioned as "Clown." Feste seems to leave Olivia's house and return at ...

Singapore
Singapore, officially the Republic of Singapore, is an island country and city-state in Southeast Asia. The country's territory comprises one main island, 63 satellite islands and islets, and one outlying islet. It is about one degree of latitude () north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south along with the Riau Islands in Indonesia, the South China Sea to the east, and the Straits of Johor along with the State of Johor in Malaysia to the north. In its early history, Singapore was a maritime emporium known as '' Temasek''; subsequently, it was part of a major constituent part of several successive thalassocratic empires. Its contemporary era began in 1819, when Stamford Raffles established Singapore as an entrepôt trading post of the British Empire. In 1867, Singapore came under the direct control of Britain as part of the Straits Settlements. During World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Singapore LRT
The Light Rail Transit system, locally known by the initialism LRT, are a series of localised automated guideway transit (AGT) systems in Singapore which acts as feeder services to the heavy rail Mass Rapid Transit (MRT), and together forms the core of the country's rail transport services. The first LRT line was opened in 1999 and the system has since expanded to two lines, each serving three new towns, namely Bukit Panjang, Sengkang and Punggol, with a total system length of approximately . Trains on these lines have at least one station interchange link to the MRT. The conventional definition of light rail generally refers to an upgraded form of tram that uses articulated low-floor tram cars and partial grade separation; in some cases such as the Docklands Light Railway (DLR) in London or the Skytrain in Vancouver, LRT refers to a medium-capacity rail-based light metro system. However, the term "LRT" in Singaporean parlance refers to rubber-tired automated people mover ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromated Copper Arsenate
Chromated copper arsenate (CCA) is a wood preservative containing compounds of chromium, copper, and arsenic, in various proportions. It is used to impregnate timber and other wood products, especially those intended for outdoor use, in order to protect them from attack by microbes and insects. Like other copper-based wood preservatives, it imparts a greenish tint to treated timber. CCA was invented in 1933 by Indian chemist Sonti Kamesam, and patented in Britain in 1934. It has been used for timber treatment since the mid-1930s, and is marketed under many trade names. In 2003, the United States Environmental Protection Agency and the lumber industry agreed to discontinue the use of CCA-treated wood in most residential construction. This agreement was intended to protect the health of humans and the environment by reducing exposure to the arsenic in CCA-treated wood. As a result of this decision, CCA-treated wood can no longer be used to construct residential structures such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
