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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prague
Prague ( ; cs, Praha ; german: Prag, ; la, Praga) is the capital and largest city in the Czech Republic, and the historical capital of Bohemia. On the Vltava river, Prague is home to about 1.3 million people. The city has a temperate oceanic climate, with relatively warm summers and chilly winters. Prague is a political, cultural, and economic hub of central Europe, with a rich history and Romanesque, Gothic, Renaissance and Baroque architectures. It was the capital of the Kingdom of Bohemia and residence of several Holy Roman Emperors, most notably Charles IV (r. 1346–1378). It was an important city to the Habsburg monarchy and Austro-Hungarian Empire. The city played major roles in the Bohemian and the Protestant Reformations, the Thirty Years' War and in 20th-century history as the capital of Czechoslovakia between the World Wars and the post-war Communist era. Prague is home to a number of well-known cultural attractions, many of which survived the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Praha-Smíchov Railway Station
Praha-Smíchov railway station ( cs, Nádraží Praha-Smíchov, ) 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. All trains going from Prague towards Plzeň and Písek pas ...

Karlín
Karlín (german: Karolinenthal) 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 January 1, 1922, Karlín was incorporated into Prague. At this time, the electrical engineering pioneer and industrialist František Křižík had great influe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, 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 a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

České Velenice
České Velenice (, german: Unterwielands, Gmünd-Wielands, Gmünd-Bahnhof, 1938–45: Gmünd III)) is a town in Jindřichův Hradec District in the South Bohemian Region of the Czech Republic. It has about 3,500 inhabitants. It lies on the border with Austria and shares the railway and pedestrian border crossing with Gmünd. History Until 1870, there were only small settlements of Česká Cejle, Josefsko and Dolní Velenice in the area constituting current České Velenice, and it was part of the Austrian town of Gmünd. In 1868 the main railway station and the factory for repairing rolling stock and locomotives were established. The development of this border area was decisively increased by the inauguration of the Emperor Franz Joseph Railway connecting Vienna to Prague in 1869. Due to the construction, housing estates were built and the population grew, especially of Czech nationality. At the end of World War I, the Treaty of Saint-Germain-en-Laye (1919) awarded the territory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 works built by the Sequential Excavation Method are very attractive from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Czech Koruna
The koruna, or crown, (sign: Kč; code: CZK, cs, koruna česká) has been the currency of the Czech Republic since 1993. The koruna is one of the European Union's 9 currencies, and the Czech Republic is legally bound to adopt the euro currency in the future. The official name in Czech is (plural , though the zero-grade 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 crown replaced the florin, at the rate of one florin to two crow ... [...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, railway, and industrial noise sources – other than cessation of the source activity or use of source controls. In the case of surface transportation noise, other methods of reducing the source noise intensity include encouraging the use of hybrid and electric vehicles, improving automobile aerodynamics and tire design, and choosing low-noise 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. I-680 in Milpitas, California was the first noise barrier. In the late 1960s, analytic acoustical t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 bundles) then have a tough r ...

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 supp ...

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). It is named after the Italian physicist Alessandro Volta (1745–1827). 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. 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. 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 equivalent to electronvolts per elementary charge: : \text = \text\Omega = \frac = \ ...
