Nové Spojení
The ''Nové spojení'' (Czech for "New Connection", full name ''Nové spojení Praha hl.n., Masarykovo n. – Libeň, Vysočany, Holešovice'') is a series of tunnels and bridges forming an important part of the railway network in Prague, Czech Republic. The network was constructed between 2004 and 2008 and opened in 2010. It links the two central stations, Praha hlavní and Praha Masarykovo, to Libeň, Vysočany and Holešovice stations and the start of their respective mainline corridors towards Česká Třebová, Hradec Králové and Ústí nad Labem. The construction has increased the capacity of the trunk lines serving Praha hlavní nádraží, allowing more trains to terminate there. Prior to its completion, many international trains terminated at Holešovice station, due to lack of access to the centre from the northern and eastern routes. Trains are now also able to travel at speeds of up to on the tunnel sections. The construction is also part of a larger plan to ...

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 or the road etc. 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. Road-grade crossings are considered incompatible with high-speed rail and are virtually non-existent in European high-speed train operations.

Praha-Smíchov Railway Station
Praha-Smíchov railway station (, ) is a major railway station in Prague, Czech Republic, located in Smíchov, in the south-west of the city. It serves as a major railway station on the Czech national rail network, and is connected to the rest of Prague by its metro station of the same name and numerous tram routes which stop on Nádražní street outside the station. It is also a major bus terminus for lines going to the south and southwest of Prague and beyond. In 2009 the station served almost 4 million people. The station was opened in 1862 as the terminus of the line linking Prague to Plzeň, operated by ''Česká Západní Dráha'' (Czech Western Railway). In 1872 and 1873, two more lines were built to the station, one from Hostivice and the other from Rudná. The present station building was built between 1953 and 1956 and designed by architects Jan Zázvorka and Ladislav Žák.

Karlín
Karlín () is a cadastral area of Prague, part of Prague 8 municipal district, formerly an independent town (which became part of Prague in 1922). It is bordered by the river Vltava and Holešovice to the north, Vítkov hill and Žižkov to the south, New Town to the west and Libeň to the east. History The building of the Karlín district began in 1817, surrounding the Rosarium of the Knights of the Cross with the Red Star. The new settlement was named after the fourth wife of Emperor Francis I of Austria, Caroline Augusta of Bavaria. After the demolition of the city walls, the properties in Karlín were counted among the cheapest properties of Prague. For that reason, the number of industrial enterprises and dwellings grew very quickly in the area of "Rohan Island" (''Rohanský ostrov''). On 1 January 1922 Karlín was incorporated into Prague. At this time, the electrical engineering pioneer and industrialist František Křižík had great influence in the area. He est ...

Austria
Austria, formally the Republic of Austria, is a landlocked country in Central Europe, lying in the Eastern Alps. It is a federation of nine Federal states of Austria, states, of which the capital Vienna is the List of largest cities in Austria, most populous city and state. Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has Austrians, a population of around 9 million. The area of today's Austria has been inhabited since at least the Paleolithic, Paleolithic period. Around 400 BC, it was inhabited by the Celts and then annexed by the Roman Empire, Romans in the late 1st century BC. Christianization in the region began in the 4th and 5th centuries, during the late Western Roman Empire, Roman period, followed by the arrival of numerous Germanic tribes during the Migration Period.

New Austrian Tunnelling Method
The new Austrian tunneling method (NATM), also known as the sequential excavation method (SEM) or sprayed concrete lining method (SCL), is a method of modern tunnel design and construction employing sophisticated monitoring to optimize various wall reinforcement techniques based on the type of rock encountered as tunneling progresses. This technique first gained attention in the 1960s based on the work of Ladislaus von Rabcewicz, Leopold Müller, and Franz Pacher between 1957 and 1965 in Austria. The name NATM was intended to distinguish it from earlier methods, with its economic advantage of employing inherent geological strength available in the surrounding rock mass to stabilize the tunnel wherever possible rather than reinforcing the entire tunnel. NATM/SEM is generally thought to have helped revolutionise the modern tunneling industry. Many modern tunnels have used this excavation technique. The Sequential Excavation Method is very cost effective, even in karst conditions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Czech Koruna
The koruna, or crown (sign: Kč; code: CZK, ), has been the currency of the Czech Republic since 1993. The koruna is one of the European Union's eight currencies, and the Czech Republic is legally bound to adopt the euro in the future. The official name in Czech is (plural , though the zero-suffixed genitive plural form is used on banknotes and coins of value 5 Kč or higher). The ISO 4217 code is CZK and the local acronym is Kč, which is placed after the numeric value (e.g., "50 Kč") or sometimes before it (as is seen on the 10-koruna coin). One crown is made up of 100 '' hellers'' (abbreviated as "h", official name in Czech: singular: , nominative plural: , genitive plural: – used with numbers higher or equal to 5 – e.g. ), but hellers have now been withdrawn from circulation, and the smallest unit of physical currency is 1 Kč. History In 1892, the Austro-Hungarian krone replaced the gulden at the rate of two kronen to one gulden (which is also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noise Barrier
A noise barrier (also called a soundwall, noise wall, sound berm, sound barrier, or acoustical barrier) is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution. Noise barriers are the most effective method of mitigating roadway noise, roadway, railway, and industrial noise sources – other than cessation of the source activity or use of source controls. In the case of surface transportation noise, Noise mitigation#Roadways, other methods of reducing the source noise intensity include encouraging the use of Hybrid vehicles, hybrid and electric vehicles, improving Automotive aerodynamics, automobile aerodynamics and tire design, and choosing low-noise Pavement (material), paving material. Extensive use of noise barriers began in the United States after noise regulations were introduced in the early 1970s. History Noise barriers have been built in the United States since the mid-twentieth century, when vehicular traffic burgeoned. ...

Fibre-optic Cable
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for fiber-optic communication in different applications, for example long-distance telecommunication or providing a high-speed data connection between different parts of a building. Design Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers (or fibers formed into ribbons or ...

DC Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify '' current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power ...

Kilovolt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. It can be expressed in terms of SI base units ( m, kg, s, and A) as : \text = \frac = \frac = \frac = \text\text^2\text^. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, s, and A) as : \text = \frac = \frac = \frac = \text\text^2\text^. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivale ...
