Summit Tunnel
Summit Tunnel in England is one of the world's oldest railway tunnels. It was constructed between 1838 and 1841 by the Manchester and Leeds Railway Company to provide a direct line between Leeds and Manchester. When built, Summit Tunnel was the longest railway tunnel in the world. The tunnel, between Littleborough and Walsden near Todmorden, was bored beneath the Pennines, a natural obstruction to most forms of traffic. The tunnel is just over long and carries two standard-gauge tracks in a single horseshoe-shaped tube, approximately wide and high. Summit Tunnel was designed by Thomas Longridge Gooch, assisted by Barnard Dickinson. Progress on its construction was slower than anticipated, largely because excavation was more difficult than anticipated. On 1 March 1841, Summit Tunnel was opened by Sir John Frederick Sigismund Smith; it had cost of £251,000 and 41 workers had died. On 20 December 1984, the Summit Tunnel fire occurred. There were no deaths and five months lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Rail
Northern Rail, branded as Northern, was an English train operating company owned by Serco-Abellio that operated the Northern Rail franchise from 2004 until 2016. It was the primary passenger train operator in Northern England, and operated the most stations of any train operating company in the United Kingdom. Northern Rail was replaced on 1 April 2016 by Arriva Rail North. History In 2000 the Strategic Rail Authority announced that it planned to reorganise the North West Regional Railways and Regional Railways North East franchises operated by First North Western and Arriva Trains Northern. A TransPennine Express franchise would be created for the long-distance regional services, with the remaining services to be operated by a new Northern Rail franchise. On 1 July 2004 the Strategic Rail Authority awarded the franchise to Serco-NedRailways, beating FirstGroup. The franchise was awarded for six years and nine months, with a two-year extension subject to performance target ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Stephenson
Robert Stephenson Fellow of the Royal Society, FRS HFRSE FRSA Doctor of Civil Law, DCL (16 October 1803 – 12 October 1859) was an English civil engineer and designer of locomotives. The only son of George Stephenson, the "Father of Railways", he built on the achievements of his father. Robert has been called the greatest engineer of the 19th century. Life Robert was born in Willington Quay near Wallsend, Northumberland, the son of George Stephenson and his wife, Frances Henderson. The family moved to Killingworth, where Robert was taught at the local village school. Robert attended the middle-class Percy Street Academy in Newcastle and at the age of fifteen was apprenticed to the mining engineer Nicholas Wood. He left before he had completed his three years to help his father survey the Stockton and Darlington Railway. Robert spent six months at Edinburgh University before working for three years as a mining engineer in Colombia. When he returned his father was building t ...

Bricklayer
A bricklayer, which is related to but different from a mason, is a craftsman and tradesman who lays bricks to construct brickwork. The terms also refer to personnel who use blocks to construct blockwork walls and other forms of masonry. In British and Australian English, a bricklayer is colloquially known as a "brickie". A stone mason is one who lays any combination of stones, cinder blocks, and bricks in construction of building walls and other works. Bricklaying is a part of masonry. Bricklaying may also be enjoyed as a hobby. For example, the former British Prime Minister Winston Churchill did bricklaying as a hobby. Bricklayers occasionally enter competitions where both speed and accuracy are judged. The largest is the "Spec-Mix Bricklayer 500" held annually in Las Vegas, Nevada, USA. Required training Bricklaying and masonry are ancient professions that even centuries later require modern training. Bricklayers usually go through a formal apprenticeship which includ ...

Industrial Action
Industrial action (British English) or job action (American English) is a temporary show of dissatisfaction by employees—especially a strike action, strike or slowdown or working to rule—to protest against bad working conditions or low pay and to increase bargaining power with the employer and intended to force the employer to improve them by reducing productivity in a workplace. Industrial action is usually organized by trade unions or other organised labour, most commonly when employees are forced out of work due to contract termination and without reaching an agreement with the employer. Quite often it is used and interpreted as a euphemism for strike action, strike or mass strike, but the scope is much wider. Industrial action may take place in the context of a labour dispute or may be meant to effect political or social change. This form of communication tends to be their only means to voice their concerns about safety and benefits. Types *Strike action, Strike *Occup ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Bedrock
In geology, bedrock is solid Rock (geology), rock that lies under loose material (regolith) within the crust (geology), crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysics, geophysical methods is an important task in most civil engineering projects. Superficial deposition (geology), deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave ...

Ventilation Shaft
In subterranean civil engineering, ventilation shafts, also known as airshafts or vent shafts, are vertical passages used in mines and tunnels to move fresh air underground, and to remove stale air. In architecture, an airshaft is a small, vertical space within a tall building which permits ventilation of the building's interior spaces to the outside. The floor plan of a building with an airshaft is often described as a "square donut" shape. Alternatively, an airshaft may be formed between two adjacent buildings. Windows on the interior side of the donut allow air from the building to be exhausted into the shaft, and, depending on the height and width of the shaft, may also allow extra sunlight inside. See also * Ventilation (architecture) * Stack effect * Underground mine ventilation * Courtyard * Lightwell * Skylight * Atrium (architecture) In architecture, an atrium (plural: atria or atriums) is a large open-air or skylight-covered space surrounded by a building. Atria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railroad Tie
A railroad tie, crosstie (American English), railway tie (Canadian English) or railway sleeper (Australian and British English) is a rectangular support for the rails in railroad tracks. Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge. Railroad ties are traditionally made of wood, but prestressed concrete is now also widely used, especially in Europe and Asia. Steel ties are common on secondary lines in the UK; plastic composite ties are also employed, although far less than wood or concrete. As of January 2008, the approximate market share in North America for traditional and wood ties was 91.5%, the remainder being concrete, steel, azobé (red ironwood) and plastic composite. Tie spacing may depend on the type of tie, traffic loads and other requirements, for example 2640 concrete ties per mile on North American mainline railroads to 2112 timber ties per mile ...

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
40085 Emerges From Summit Tunnel At Littleborough
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other hand, t ...

Kingston Upon Hull
Kingston upon Hull, usually abbreviated to Hull, is a port city and unitary authority in the East Riding of Yorkshire, England. It lies upon the River Hull at its confluence with the Humber Estuary, inland from the North Sea and south-east of York, the historic county town. With a population of (), it is the fourth-largest city in the Yorkshire and the Humber region after Leeds, Sheffield and Bradford. The town of Wyke on Hull was founded late in the 12th century by the monks of Meaux Abbey as a port from which to export their wool. Renamed ''Kings-town upon Hull'' in 1299, Hull had been a market town, military supply port, trading centre, fishing and whaling centre and industrial metropolis. Hull was an early theatre of battle in the English Civil Wars. Its 18th-century Member of Parliament, William Wilberforce, took a prominent part in the abolition of the slave trade in Britain. More than 95% of the city was damaged or destroyed in the blitz and suffered a perio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
