Crossbucks
A crossbuck is a traffic sign used to indicate a level railway crossing. It is composed of two slats of wood or metal of equal length, fastened together on a pole in a saltire formation (resembling the letter X). Crossbucks are sometimes supplemented by electrical warnings of flashing lights, a bell, or a boom barrier that descends to block the road and prevent traffic from crossing the tracks. Vienna Convention The Vienna Convention on Road Signs and Signals, a multilateral treaty of the United Nations with the intention of standardizing traffic signs around the world, prescribes several different regulations for the "crossbuck" sign. The sign should consist of two arms not less than long, crossed in the form of an . The first model may have a white or yellow ground with a thick red or black border. The second model may have a white or yellow ground with a thin black border and an inscription, such as "RAILWAY CROSSING". If lateral clearance obstructs the placement of the si ...

Boom Barrier
A boom barrier, also known as a boom gate, is a bar, or pole pivoted to allow the boom to block vehicular or pedestrian access through a controlled point. Typically the tip of a boom gate rises in a vertical arc to a near vertical position. Boom gates are often counterweighted, so the pole is easily tipped. Boom gates are often paired either end to end, or offset appropriately to block traffic in both directions. Some boom gates also have a second arm which hangs 300 to 400 mm below the upper arm when lowered, to increase approach visibility, and which hangs on links so it lies flat with the main boom as the barrier is raised. Some barriers also feature a pivot roughly half way, where as the barrier is raised, the outermost half remains horizontal, with the barrier resembling an upside-down ''L'' when raised. Automatic boom barrier There are various technologies for an automatic boom barrier. One of them is electro-mechanical, which is widely used due to its reliability. The o ...

Manual On Uniform Traffic Control Devices
The ''Manual on Uniform Traffic Control Devices for Streets and Highways'' (usually referred to as the ''Manual on Uniform Traffic Control Devices'', abbreviated MUTCD) is a document issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT) to specify the standards by which traffic signs, road surface markings, and signals are designed, installed, and used. In the United States, all traffic control devices must legally conform to these standards. The manual is used by state and local agencies as well as private construction firms to ensure that the traffic control devices they use conform to the national standard. While some state agencies have developed their own sets of standards, including their own MUTCDs, these must substantially conform to the federal MUTCD. The MUTCD defines the content and placement of traffic signs, while design specifications are detailed in a companion volume, ''Standard Highway Signs''. This manual de ...

Level Crossings
A level crossing is an intersection where a railway line crosses a road, path, or (in rare situations) airport runway, at the same level, as opposed to the railway line crossing over or under using an overpass or tunnel. The term also applies when a light rail line with separate 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 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 became commonplace in many areas, as they protected the railway fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saltire
A saltire, also called Saint Andrew's Cross or the crux decussata, is a heraldic symbol in the form of a diagonal cross, like the shape of the letter X in Roman type. The word comes from the Middle French ''sautoir'', Medieval Latin ''saltatoria'' (" stirrup"). From its use as field sign, the saltire came to be used in a number of flags, in the 16th century for Scotland and Burgundy, in the 18th century also as the ensign of the Russian Navy, and for Ireland. Notable 19th-century usage includes some of the flags of the Confederate States of America. It is also used in the flag of Jamaica and on seals, and as a heraldic charge in coats of arms. The term saltirewise or in saltire refers to heraldic charges arranged as a diagonal cross. The shield may also be divided per saltire, i.e. diagonally. A warning sign in the shape of a saltire is also used to indicate the point at which a railway line intersects a road at a level crossing. Heraldry and vexillology The saltire i ...

Iconograph
{{Unreferenced, date=December 2009 An iconograph is a picture formed by a word or words. It can take the form of irregularly shaped letters or (especially in the case of poems) irregularly aligned text. American poet May Swenson popularized such poems in her 1970 book ''Iconographs'', which contained a number of poems laid out to resemble their subjects (e.g. a butterfly Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths.

Chevron (insignia)
A chevron (also spelled cheveron, especially in older documents) is a V-shaped mark or symbol, often inverted. The word is usually used in reference to a kind of fret in architecture, or to a badge or insignia used in military or police uniforms to indicate rank or length of service, or in heraldry and the designs of flags (see flag terminology). Ancient history Appearing on pottery and petrographs throughout the ancient world, the chevron can be considered to be one of the oldest symbols in human history, with V-shaped markings occurring as early as the Neolithic era (6th to 5th millennia BC) as part of the Vinča symbols inventory. The Vinča culture responsible for the symbols appear to have used the chevron as part of a larger proto-writing system rather than any sort of heraldic or decorative use, and are not known to have passed the symbol on to any subsequent cultures.Mäder, Michael: ''Ist die Donauschrift Schrift?''

Warning Sign
A warning sign is a type of sign which indicates a potential hazard, obstacle, or condition requiring special attention. Some are traffic signs that indicate hazards on roads that may not be readily apparent to a driver. While warning traffic sign designs vary, they usually take the shape of an equilateral triangle with a white background and thick red border. In the People's Republic of China (except for Macau and Hong Kong), they appear with a black border and a yellow background. In Sweden, Serbia, Bosnia and Herzegovina, Greece, Finland, Iceland, North Macedonia and Poland, they have a red border with an amber background. The polar bear warning sign in Svalbard recently changed from displaying a black bear on white background to a white bear on black background (both signs are triangular with a red border). Some countries (like France, Norway and Spain) that normally use a white background have adopted an orange or amber background for road work or construction signs. War ...

Regulatory Sign
A regulatory sign is used to indicate or reinforce traffic laws, regulations or requirements which apply either at all times or at specified times or places upon a street or highway, the disregard of which may constitute a violation, or a sign in general that regulates public behavior in places open to the public. The FHWA defines ''regulatory sign'' as "a sign that gives notice to road users of traffic laws or regulations". Traffic signs Regulatory traffic signs follow international conventions, usually being: * White circle or rectangle with red border, with a black pictogram, black text, or both * Blue circle or rectangle with white border and white pictogram * Red rectangle with white border and white text * Red octagon with white border and white text (stop signs only) United States Regulatory traffic signs within the United States must comply with the federal Manual on Uniform Traffic Control Devices (MUTCD) or the State MUTCD, depending on the state in which the sign is i ...

Ferrocarril Roca
The General Roca Railway (FCGR) (native name: Ferrocarril General Roca) is a broad gauge railway in Argentina which runs from Constitución station in Buenos Aires to the south of the country through the provinces of Buenos Aires, La Pampa, Neuquén and Río Negro. It was also one of the six state-owned Argentine railway divisions formed after President Juan Perón's nationalisation of the railway network in 1948, being named after former president Julio Argentino Roca.
