Rapid Transit In Greece
Rapid transit in Greece refers to the systems of rapid transit at present active in Greece. A "rapid transit", "underground", "subway", "elevated railway", "metro" or "metropolitan railway" system is an electric passenger railway in an urban area with a high capacity and frequency, and grade separation from other traffic.; Rapid transit systems are typically located either in tunnels or on elevated rails above street level. Outside urban centers, rapid transit lines may run on grade separated ground level tracks. In Greece there are several systems that are called "Rapid Transit": * Athens Metro, an underground and overground railway network serving the city of Athens since 1904; * Athens Tram, a tram network serving the city of Athens, began electrified service in 1908 and revived in 2001; * Thessaloniki Metro The Thessaloniki Metro ( el, Μετρό Θεσσαλονίκης, ', ) is an underground rapid-transit system under construction in Thessaloniki, Greece's second larg ...

Rapid Transit
Rapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport generally found in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways (usually electric railway, electric) that operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles, and which is often grade-separated in tunnels or on elevated railways. Modern services on rapid transit systems are provided on designated lines between rapid transit station, stations typically using electric multiple units on rail tracks, although some systems use guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train a ...

Grade Separation
In civil engineering (more specifically highway engineering), grade separation is a method of aligning a junction of two or more surface transport axes at different heights (grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways. Bridges (or overpasses, also called flyovers), tunnels (or underpasses), or a combination of both can be built at a junction to achieve the needed grade separation. In North America, a grade-separated junction may be referred to as a ''grade separation'' or as an '' interchange'' – in contrast with an '' intersection'', ''at-grade'', a ''diamond crossing'' or a ''level crossing'', which are not grade-separated. Effects Advantages Roads with grade separation generally allow traffic to move freely, with fewer interruptions, and at higher overall ...

Athens Metro
The Athens Metro ( el, Μετρό Αθήνας, Metro Athinas, translit-std=iso) is a rapid-transit system in Greece which serves the Athens urban area and parts of East Attica. Line 1 opened as a conventional steam railway in 1869 and electrified in 1904. In 1991, Attiko Metro S.A. constructed and extended Lines 2 and 3. It has significantly changed Athens by providing a much-needed solution to the city's traffic and air pollution problem, as well as revitalising many of the areas it serves. Extensions of existing lines are under development, as well as a new Line 4, whose central section began construction in October 2021. The Athens Metro is actively connected with the other means of public transport, such as buses, trolleys, the Athens Tram and the Athens Suburban Railway. The Athens Metro is hailed for its modernity (mainly the newer lines 2, 3) and many of its stations feature works of art, exhibitions and displays of the archaeological remains found during its construc ...

Athens
Athens ( ; el, Αθήνα, Athína ; grc, Ἀθῆναι, Athênai (pl.) ) is both the capital and largest city of Greece. With a population close to four million, it is also the seventh largest city in the European Union. Athens dominates and is the capital of the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years and its earliest human presence beginning somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state. It was a centre for the arts, learning and philosophy, and the home of Plato's Academy and Aristotle's Lyceum. It is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political influence on the European continent—particularly Ancient Rome. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Gre ...

Athens Tram
The Athens Tram is the modern public tram network system serving Athens, Greece. The system is owned and operated by STASY, which replaced Tram S.A. in June 2011. STASY operates a fleet of 25 Alstom Citadis and 35 Sirio vehicles, which serve two tram lines and 60 stops. The tram network spans a total length of throughout ten Athenian suburbs. This network runs from Syntagma (central Athens) to the coastal suburb of Palaio Faliro, where the line splits in two branches: the first runs along the Athens coastline toward the southern suburb of Voula, while the other heads toward the port of Piraeus. The network covers the majority of the city's Saronic Gulf coastline. Athens' tram system provides average daily service to 65,000 passengers, and employs 345 people. History Old tram networks (1908-1960) Athens Tram began its operations in 1882 with horse tramways. After 1908, the metre gauge tram network was electrified and was extended to 21 lines. The original Athens tram syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thessaloniki Metro
The Thessaloniki Metro ( el, Μετρό Θεσσαλονίκης, ', ) is an underground rapid-transit system under construction in Thessaloniki, Greece's second largest city. Estimates for the cost of the megaproject are €1.62 billion ( $ billion) for the main line and €640 million ($ million) for the Kalamaria extension, for a total of €2.26 billion ($ billion). The project is primarily funded with loans from the European Investment Bank (EIB) and the European Regional Development Fund (ERDF) and funds from the Greek government. Construction by a Greek-Italian consortium is overseen by Attiko Metro S.A., the Greek state-owned company which oversaw construction of the Athens Metro and Athens Tram. Proposed during the 1910s and first seriously planned in the 1980s, construction of the main line began in 2006 and on the Kalamaria extension in 2013. Although the initial proposal included three extensions to the main line, the latest Attiko Me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Railways In Greece
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 posit ...
