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 ... [...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 Regional Railways North West 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-Abellio, Serco-NedRailways, beating FirstGroup. The franchise was awarded for six years and nine months, with a two-year extension subject to perform ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Stephenson
Robert Stephenson , (honoris causa, Hon. causa) (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. Stephenson's death was widely mourned, and his funeral afforded marks of public honour. He is buried in Westminster Abbey. Early life Robert Stephenson was born on 16 October 1803, at Willington Quay, east of Newcastle upon Tyne, to George Stephenson and Frances ( Henderson), usually known as Fanny. She was twelve years older than George, and when they met she was working as a servant where George was lodging. After marrying, George and Fanny lived in an upper room of a cottage; George worked as a brakesman on the Stationary steam engine, stationary winding engine on the Quay, and in his spare time he cleaned and mended clocks and repaired shoes.In 1804, George bec ...

New Year's Eve
In the Gregorian calendar, New Year's Eve refers to the evening, or commonly the entire day, of the last day of the year, 31 December, also known as Old Year's Day. In many countries, New Year's Eve is celebrated with dancing, eating, drinking, and watching or lighting fireworks. Many Christians attend a watchnight service to mark the occasion. New Year's Eve celebrations generally continue into New Year's Day, January 1, 1 January, past midnight. The local time zone determines the advent of the New Year; the first places to welcome the New Year are west of the International Date Line: the Line Islands (part of Kiribati), Samoa and Tonga, in the Pacific Ocean. In contrast, American Samoa, Baker Island and Howland Island (part of the United States Minor Outlying Islands) are among the last. By region Africa Algeria In Algeria, New Year's Eve is usually celebrated with family and friends. In the largest cities, there are fireworks at midnight. The Martyrs' Memorial, Algiers, Ma ...

Bricklayer
A bricklayer, which is related to but different from a mason, is a craftsperson and tradesperson 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 Professional bricklayers usually go through a formal apprenticeship which includes about three to four years of on-the-job training combined with classroom ins ...

Industrial Action
Industrial action (British English) or job action (American English) is a temporary show of dissatisfaction by employees—especially a 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 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 * Blue flu * General strike ( mass strike) * Occupatio ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of Clay mineral, clay minerals (hydrous aluminium phyllosilicates, e.g., Kaolinite, kaolin, aluminium, Al2Silicon, Si2Oxygen, O5(hydroxide, 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 (Lamination (geology), laminae) less than one centimeter in thickness. This property is called ''Fissility (geology), 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 narrower 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 in ...

Bedrock
In geology, bedrock is solid rock that lies under loose material ( regolith) within the 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 geophysical methods is an important task in most civil engineering projects. Superficial 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 it susceptible to erosion. Bedrock may also experience subsur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, also known as a lightwell, is typically 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 A skylight (sometimes called a rooflight) is a light-permitting structure or window, usually made of transpare ...

Blackpool
Blackpool is a seaside town in Lancashire, England. It is located on the Irish Sea coast of the Fylde peninsula, approximately north of Liverpool and west of Preston, Lancashire, Preston. It is the main settlement in the Borough of Blackpool, borough of the same name. Blackpool was originally a small hamlet; it began to grow in the mid-eighteenth century, when sea bathing for health purposes became fashionable. Blackpool's beach was suitable for this activity, and by 1781 several hotels had been built. The opening of a railway station in 1846 allowed more visitors to reach the resort, which continued to grow for the remainder of the nineteenth century. In 1876, the town became a borough. Blackpool's development was closely tied to the Lancashire cotton mill, cotton-mill practice of annual factory maintenance shutdowns, known as wakes weeks, when many workers chose to visit the seaside. The town saw large growth during the late Victorian and Edwardian periods. By 1951 its popu ... [...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 on North American mainline railroads to on London, Midland and Scottish Railway joi ...

Steam Engine
A steam engine is a heat engine that performs Work (physics), 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 (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they 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 Boiler (power generation), boilers etc.), such as railway steam locomot ...

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 a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga would add a horizontal line on top of the digit, and the Kshatrapa and Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, ending up with a digit very close to the original Brahmin cross. While the shape of the character ...
