Wainhill Crossing Halt Railway Station
Wainhill Crossing Halt was a halt on the Watlington and Princes Risborough Railway which the Great Western Railway opened in 1925 to serve the Oxfordshire hamlet of Wainhill. The opening of the halt was part of a GWR attempt to encourage more passengers on the line at a time when competition from bus services was drawing away patronage. History Opened in 1925, the halt - the last station to open on the line - sought to encourage passenger traffic in the face of increased competition from buses. It was situated to the south of a level crossing over an unclassified road leading to Lower Wainhill and Hempton Wainhill. The lane saw very occasional traffic as it was unsuitable for motor vehicles and only served nine or ten houses on the eastern side of the Watlington and Princes Risborough Railway. A modest crossing keeper's cottage had been provided by the railway company which comprised two ground floor rooms and one bedroom on the first floor; there was no mains water, gas or e ...

Chinnor
Chinnor is a large village and Civil parishes in England, civil parish in South Oxfordshire about southeast of Thame, close to the border with Buckinghamshire. The village is a spring line settlement on the Icknield Way below the Chiltern Hills, Chiltern escarpment. Since 1932 the civil parish has included the village of Emmington. The United Kingdom Census 2011, 2011 Census recorded the parish's population as 5,924. Pre-history The Icknield Way is a pre-Roman Britain, Roman road. The site of an British Iron Age, Iron Age settlement from perhaps the 4th century BC has been excavated on the Chiltern ridge in the southern part of the parish. Traces of Romano-British culture, Romano-British occupation have been found both on the same high ground and below on Icknield Way. A twin Tumulus, barrow on Icknield Way has been found to contain the weapons of a Saxons, Saxon warrior that have been dated to the 6th century. Chinnor's Toponymy, toponym may originally have meant the ''ora'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Lamp
A kerosene lamp (also known as a paraffin lamp in some countries) is a type of lighting device that uses kerosene as a fuel. Kerosene lamps have a wick or mantle as light source, protected by a glass chimney or globe; lamps may be used on a table, or hand-held lanterns may be used for portable lighting. Like oil lamps, they are useful for lighting without electricity, such as in regions without rural electrification, in electrified areas during power outages, at campsites, and on boats. There are three types of kerosene lamp: flat-wick, central-draught (tubular round wick), and mantle lamp. Kerosene lanterns meant for portable use have a flat wick and are made in dead-flame, hot-blast, and cold-blast variants. Pressurized kerosene lamps use a gas mantle; these are known as Petromax, Tilley lamps, or Coleman lamps, among other manufacturers. They produce more light per unit of fuel than wick-type lamps, but are more complex and expensive in construction and more complex to oper ...

Former Great Western Railway Stations
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the a ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects radiation (usually light) back to its source with minimum scattering. This works at a wide range of angle of incidence, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence. Being directed, the retroflector's reflection is brighter than that of a diffuse reflector. Corner reflectors and cat's eye reflectors are the most used kinds. Types There are several ways to obtain retroreflection: Corner reflector A set of three mutually perpendicular reflective surfaces, placed to form the internal corner of a cube, work as a retroreflector. The three corresponding normal vectors of the corner's sides form a basis in which to represent the direction of an arbitrary incoming ray, . When the ray reflects from the first side, say x, the ray's ''x''-component, ''a'', is reversed to −''a'', while the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinnor And Princes Risborough Railway
The Chinnor and Princes Risborough Railway is a preserved standard gauge heritage railway with its headquarters and main station at Chinnor in South Oxfordshire, England. It runs along the foot of the Chilterns escarpment. Although a few fields away it has since been given the nickname 'The Icknield Line' for its connection to the Lower Icknield Way. History The line was part of the former Great Western Railway branch line between Watlington and Princes Risborough. British Railways closed the line to passenger traffic in 1957. The section between Chinnor and Princes Risborough thereafter carried a freight-only cement service until 1989. Preservation Reopening The Chinnor and Princes Risborough Railway Association was formed around August 1989. On 19 May 1991, the first train - a works train headed by a 0-4-0 Baguley diesel - ran from Chinnor. It began to operate passenger trains between Chinnor and the site of the former Wainhill Halt (about 1 km NE of Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cement
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource. Cements used in construction are usually inorganic, often lime or calcium silicate based, which can be characterized as hydraulic or the less common non-hydraulic, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable in wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gypsum
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula . It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard or sidewalk chalk, and drywall. Alabaster, a fine-grained white or lightly tinted variety of gypsum, has been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, the Byzantine Empire, and the Nottingham alabasters of Medieval England. Gypsum also crystallizes as translucent crystals of selenite. It forms as an evaporite mineral and as a hydration product of anhydrite. The Mohs scale of mineral hardness defines gypsum as hardness value 2 based on scratch hardness comparison. Etymology and history The word ''gypsum'' is derived from the Greek word (), "plaster". Because the quarries of the Montmartre district of Paris have long furnished burnt gypsum (calcined gypsum) used for various purposes, this dehydrated gypsum became known ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lane
In road transport, a lane is part of a roadway that is designated to be used by a single line of vehicles to control and guide drivers and reduce traffic conflicts. Most public roads (highways) have at least two lanes, one for traffic in each direction, separated by lane markings. On multilane roadways and busier two-lane roads, lanes are designated with road surface markings. Major highways often have two multi-lane roadways separated by a median. Some roads and bridges that carry very low volumes of traffic are less than wide, and are only a single lane wide. Vehicles travelling in opposite directions must slow or stop to pass each other. In rural areas, these are often called country lanes. In urban areas, alleys are often only one lane wide. Urban and suburban one lane roads are often designated for one-way traffic. History For much of human history, roads did not need lane markings because most people walked or rode horses at relatively slow speeds. However, when a ...

South Oxfordshire
South Oxfordshire is a local government district in the ceremonial county of Oxfordshire, England. Its council is temporarily based outside the district at Abingdon-on-Thames pending a planned move to Didcot, the district's largest town. The areas located south of the River Thames are within the historic county of Berkshire. History The district was formed on 1 April 1974, under the Local Government Act 1972, covering the area of six former districts, which were abolished at the same time: *Bullingdon Rural District * Henley-on-Thames Municipal Borough *Henley Rural District *Thame Urban District * Wallingford Municipal Borough *Wallingford Rural District The two Wallingford districts had previously been part of the administrative county of Berkshire, whilst the other four districts had been in the administrative county of Oxfordshire. The new district was originally given the name "Wallingford District". The shadow authority elected in 1973 to oversee the transition request ...

Level Crossing
A level crossing is an intersection where a railway line crosses a road, Trail, path, or (in rare situations) airport runway, at the same level, as opposed to the railway line crossing over or under using an Overpass#Railway, overpass or tunnel. The term also applies when a light rail line with separate Right-of-way (railroad), right-of-way or reserved track crosses a road in the same fashion. Other names include railway level crossing, railway crossing (chiefly international), grade crossing or railroad crossing (chiefly American), road through railroad, criss-cross, train crossing, and RXR (abbreviated). There are more than 100,000 level crossings in Europe and more than 200,000 in North America. History The history of level crossings depends on the location, but often early level crossings had a Flagman (rail), flagman in a nearby booth who would, on the approach of a train, wave a red flag or lantern to stop all traffic and clear the tracks. Gated crossings bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
