Sierra Leone Government Railway
:''This article is part of the history of rail transport by country series'' The Sierra Leone Government Railway operated in Sierra Leone from 1897 to 1974. It was unusual in that it formed a national railway system constructed solely to a Narrow gauge railway, narrow gauge, whereas in other countries, gauge of such a narrow width was usually confined to feeder railways. History Beginnings A number of early proposals for a railway in the British colony of Sierra Leone date from 1872, including a proposal for a trans-Sahara railway, all of which came to naught. Finally in 1893, a proposal financed by the Liverpool Chamber of Commerce was adopted, and surveying commenced. Survey parties confronted many difficulties, especially disease, which delayed completion of the survey. Opening Construction commenced from Freetown in 1896, and the first section of railway was opened to Wellington (7 miles) by March 1897. Subsequent openings were: :* Waterloo, April 1898 :* Songo (32 miles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Rail Transport By Country
The history of rail transport began in the BCE times. It can be divided into several discrete periods defined by the principal means of track material and motive power used. Ancient systems The Post Track, a prehistoric causeway in the valley of the River Brue in the Somerset Levels, England, is one of the oldest known constructed trackways and dates from around 3838 BC, making it some 30 years older than the Sweet Track from the same area. Various sections have been designated as scheduled monuments. Evidence indicates that there was a 6 to 8.5 km long '' Diolkos'' paved trackway, which transported boats across the Isthmus of Corinth in Greece from around 600 BC.Cook, R.

Sierra Leone Railway Strike Of 1926
From January 14 to February 26, 1926, all grades of the African workers within the Railway Department of the Sierra Leone Government participated in a strike. This strike represented the first time a trade union in Sierra Leone was effective in politically organizing with a set organizational structure. It is also the first strike and act of political disobedience in which the Creole elite identified with and supported the strikers and the working class against the British colonizing power. Historical background The financial situation in Sierra Leone in the mid-1920s following World War I was not dire. While the deficit for 1921 reached £343,171, by 1923, it was at a surplus of £116,926. The high unemployment rate after the war had gradually been reduced, but the wage rates of the majority of government artisan workers, throughout this improving economic situation, had remained stagnant. In 1919, this engendered a railway strike, where the railway workers tried to build allian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-6-2T
T, or t, is the twentieth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''tee'' (pronounced ), plural ''tees''. It is derived from the Semitic Taw 𐤕 of the Phoenician and Paleo-Hebrew script (Aramaic and Hebrew Taw ת/𐡕/, Syriac Taw ܬ, and Arabic ت Tāʼ) via the Greek letter τ ( tau). In English, it is most commonly used to represent the voiceless alveolar plosive, a sound it also denotes in the International Phonetic Alphabet. It is the most commonly used consonant and the second most commonly used letter in English-language texts. History ''Taw'' was the last letter of the Western Semitic and Hebrew alphabets. The sound value of Semitic ''Taw'', Greek alphabet Tαυ (''Tau''), Old Italic and Latin T has remained fairly constant, representing in each of these; and it has also kept its original basic shape in most of these alphabets.

Hunslet Engine Company
The Hunslet Engine Company is a locomotive-building company, founded in 1864 in Hunslet, England. It manufactured steam locomotives for over 100 years and currently manufactures diesel shunting locomotives. The company is part of Ed Murray & Sons. History The early years 1864–1901 The company was founded in 1864 at Jack Lane in Hunslet by John Towlerton Leather, a civil engineering contractor, who appointed James Campbell (son of Alexander Campbell, a Leeds engineer) as his works manager. The first engine was completed in 1865. It was ''Linden'', a standard gauge delivered to Brassey and Ballard, a railway civil engineering contractor as were several of the firm's early customers. Other customers included collieries. This basic standard gauge shunting and short haul "industrial" engine was to be the main-stay of Hunslet production for many years. In 1871, James Campbell bought the company for £25,000 (payable in five instalments over two years) and the firm rema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithi ...

Rail Gauge
In rail transport, track gauge (in American English, alternatively track gage) is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A ''loading gauge'' is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A ''structure gauge'' specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. Uses of the term The most common use of the term "track gauge" refers to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desire ...

Bauxite
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), Mixture, mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium Clay minerals, clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). Bauxite appears dull in Lustre (mineralogy), luster and is reddish-brown, white, or tan. In 1821, the French people, French geologist Pierre Berthier discovered bauxite near the village of Les Baux-de-Provence, Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished Laterite, lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predomin ...
