Fell Mountain Railway System
The Fell system was the first third-rail system for steep grade railway, railways that were too steep to be Rail adhesion, worked by adhesion on the two running rails alone. It uses a raised centre rail between the two running rails to provide extra traction and braking, or braking alone. Trains are propelled by wheels or braked by shoes pressed horizontally onto the centre rail, as well as by the normal running wheels. Extra brake shoes are fitted to specially designed or adapted Fell locomotives and brake vans, and for traction the locomotive has an auxiliary engine powering horizontal wheels which clamp onto the third rail. The Fell system was developed in the 1860s and was soon superseded by various types of rack railway for new lines, but some Fell systems remained in use into the 1960s. The Snaefell Mountain Railway still uses the Fell system for (emergency) braking, but not for traction. History The Fell system was designed, developed and patented by British engineer Jo ...

Snaefell Mountain Railway Car No 4 On Mountain
Snaefell ( on, snjœ-fjall/snjó-fall – snow mountain) – ( gv, Sniaull) is the highest mountain and the only summit higher than on the Isle of Man, at above sea level. The summit is crowned by a railway station, cafe and several communications masts. Views It is a well-known saying in the Isle of Man that on a clear day six monarchy, kingdoms can be seen from the top: the Isle of Man, England, Ireland, Scotland, Wales and Heaven. Some versions add a seventh kingdom, that of Manannán (or the sea). The plaque at the summit indicates the directions of five points from Snaefell as well as their distances: * to the Mull of Galloway (Scotland) * to Sca Fell, Scafell (England) * to the Mourne Mountains, Mountains of Mourne (Northern Ireland) * to Liverpool (England) * to Dublin (Republic of Ireland) (For some reason, Wales is absent from the plaque). While highly dependent on weather conditions and visibility, all of the four countries of the United Kingdom can be seen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fell Locomotive Museum
The Fell Locomotive Museum in Featherston, New Zealand, exhibits the only remaining steam-powered Fell railway locomotive in the world. From 1877, locomotive H 199 climbed up the Rimutaka Incline using John Barraclough Fell's unique method of four grip wheels on a raised centre rail. It is housed and tended to by a group of dedicated rail enthusiasts. H 199 is one of six H class locomotives designed for use on the 1 in 15 Rimutaka Incline, where they worked for 77 years. Their story is recalled by audio-visual programmes, models, photographs and memorabilia in the museum. History At the official opening ceremony for the Rimutaka Tunnel on 3 November 1955 at Speedy's Crossing, the Minister for Railways, Mr McAlpine, presented H 199 to the Borough of Featherston for display. After H 199 completed its duties on the demolition trains removing the Incline track it was towed to Hutt Workshops where it was stored until August 1958, when it was towed to Featherston and mounted o ...

South Australian Register
''The Register'', originally the ''South Australian Gazette and Colonial Register'', and later ''South Australian Register,'' was South Australia's first newspaper. It was first published in London in June 1836, moved to Adelaide in 1837, and folded into '' The Advertiser'' almost a century later in February 1931. The newspaper was the sole primary source for almost all information about the settlement and early history of South Australia. It documented shipping schedules, legal history and court records at a time when official records were not kept. According to the National Library of Australia, its pages contain "one hundred years of births, deaths, marriages, crime, building history, the establishment of towns and businesses, political and social comment". All issues are freely available online, via Trove. History ''The Register'' was conceived by Robert Thomas, a law stationer, who had purchased for his family of land in the proposed South Australian province after be ...

Minimum Railway Curve Radius
The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions. It has an important bearing on construction costs and operating costs and, in combination with superelevation (difference in elevation of the two rails) in the case of train tracks, determines the maximum safe speed of a curve. The minimum radius of a curve is one parameter in the design of railway vehicles as well as trams; monorails and automated guideways are also subject to a minimum radius. History The first proper railway was the Liverpool and Manchester Railway, which opened in 1830. Like the tram roads that had preceded it over a hundred years, the L&M had gentle curves and gradients. Reasons for these gentle curves include the lack of strength of the track, which might have overturned if the curves were too sharp causing derailments. The gentler the curves, the greater the visibility, thus boosting safety via increased ... [...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 ...

Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of inc ...

Railcar
A railcar (not to be confused with a railway car) is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach (carriage, car), with a driver's cab at one or both ends. Some railway companies, such as the Great Western, termed such vehicles "railmotors" (or "rail motors"). Self-propelled passenger vehicles also capable of hauling a train are, in technical rail usage, more usually called "rail motor coaches" or "motor cars" (not to be confused with the motor cars, otherwise known as automobiles, that operate on roads). The term is sometimes also used as an alternative name for the small types of multiple unit which consist of more than one coach. That is the general usage nowadays in Ireland when referring to any diesel multiple unit (DMU), or in some cases electric multiple unit (EMU). In North America the term "railcar" has a much broader sense and can be used (as an abbr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

Estrada De Ferro Cantagalo
The Estrada de Ferro Cantagalo or Cantagalo Railway in Brazil operated from 1873 to 1965, and used the Fell mountain railway system, with equipment from the temporary Mont Cenis Pass Railway which closed in 1871. From 1883 the Fell rail was used for braking only. Cameron says that the line was to which the locomotives and rolling stock were converted (though another source says that the line was to the same gauge as the Mont Cenis Pass Railway). The line was built by British engineers and capital. The railway, from Niterói to Nova Friburgo, was Brazil's first mountain railway. The coastal plain was followed by a steep rise of to the inland plateau, starting at Cachoeiras de Macacu, and spread over , with the steepest section of about between Boca do Mato and Theodoro de Olivera: was 1 in 12, and between 1 in 14 and 1 in 33 (7% and 3%). Curvature was severe, from radius. The locomotives initially were 0-4-0T tank engines of about . Four new locomotives were purchased from ...

Compressed Air
Compressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air is an important medium for transfer of energy in industrial processes, and is used for power tools such as air hammers, drills, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles. Brakes applied by compressed air made large railway trains safer and more efficient to operate. Compressed air brakes are also found on large highway vehicles. Compressed air is used as a breathing gas by underwater divers. It may be carried by the diver in a high pressure diving cylinder, or supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing apparatus used by firefighters, mine rescue workers and industrial workers in hazardous atmospheres. In Europe, 10 percent of all industrial electricity consumption is to produce compressed air—amountin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
