Copenhagen Metro
The Copenhagen Metro ( da, Københavns Metro, ) is a 24/7 rapid transit system in Copenhagen, Denmark, serving the municipalities of Copenhagen, Frederiksberg, and Tårnby. The original system opened in October 2002, serving nine stations on two lines: M1 and M2. In 2003 and 2007, the Metro was extended to Vanløse and Copenhagen Airport (Lufthavnen) respectively, adding an additional six plus five stations to the network. In 2019, seventeen stations on a wholly underground circle line, the M3, was added bringing the number of stations to 37.MetroselskabetCityringen åbner The driverless light metro supplements the larger S-train rapid transit system, and is integrated with local DSB and regional (Øresundståg) trains and municipal Movia buses.

M2 (Copenhagen)
M2 is a line of the Copenhagen Metro, colored yellow on the map. It runs from Vanløse to Lufthavnen through the center of Copenhagen, sharing track with the M1 from Vanløse to Christianshavn. The line was built along with M1 as part of the redevelopment of Ørestad. The principle of the line was passed in 1992, and construction commenced in 1998. The line opened in several stages between 2002 and 2007. It is owned by Metroselskabet and operated by Metro Service, and operates with a headway between four and twenty minutes. The line is long, and runs in a tunnel through the city center between Lindevang and Amager Strand. It connects the western borough of Vanløse and the municipality of Frederiksberg to the city center of Copenhagen, as well as the eastern parts of Amager and Copenhagen Airport. It provides transfer to the S-train at three stations and to DSB trains at two stations. Its southern end, in the district of Amager Øst, largely follows the same route as a disuse ...

M1 (Copenhagen)
M1 of the Copenhagen Metro, colored green on the map, runs from Vanløse to Vestamager. It connects the Ørestad neighborhood of Copenhagen, Denmark, to the city center. The line is elevated while traveling through Ørestad, while it runs in a tunnel below the city center. From Christianshavn to Vanløse, the line is shared with M2. History The background for the metro was the urban development of the Ørestad area of Copenhagen. The principal of building a rail transit was passed by the Parliament of Denmark on 24 June 1992, with the ''Ørestad Act''. The responsibility for developing the area, as well as building and operating the metro, was given to the Ørestad Development Corporation, a joint venture between Copenhagen Municipality (45%) and the Ministry of Finance (55%). Initially, three modes of transport were considered: a tramway, a light rail and a rapid transit. In October 1994, the Development Corporation chose a light rapid transit system.

Rome Metro
The Rome Metro ( it, Metropolitana di Roma) is a rapid transit system that operates in Rome, Italy. It started operation in 1955, making it the oldest in the country. The Metro comprises three lines – A (orange), B (blue) and C (green) – which operate on of route, serving 73 stations.Counting Termini, the interchange station between Lines A and B, and San Giovanni, the interchange station between Lines A and C, only once. The original lines in the system, lines A and B, form an X shape with the lines intersecting at '' Termini'' station, the main train station in Rome. Line B splits at the ''Bologna'' station into two branches. The third line opened in 2014 and connects to the rest of the system through an interchange with Line A at '' San Giovanni''. Rome's local transport provider, ATAC, operates the Metro and several other rail services: the Roma–Giardinetti line and the Roma–Nord line. The Roma–Lido, which connects Rome to Ostia, on the sea, used to be ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platform Screen Door
Platform screen doors (PSDs), also known as platform edge doors (PEDs), are used at some train, rapid transit and people mover stations to separate the Railway platform, platform from train tracks, as well as on some bus rapid transit, tram and light rail systems. Primarily used for passenger safety, they are a relatively new addition to many metro systems around the world, some having been retrofitted to established systems. They are widely used in newer Asian and European metro systems, and Latin America, Latin American bus rapid transit systems. History The idea for platform edge doors dates as early as 1908, when Charles S. Shute of Boston was granted a patent for "Safety fence and gate for railway-platforms". The invention consisted of "a fence for railway platform edges", composed of a series of pickets bolted to the platform edge, and vertically movable pickets that could retract into a platform edge when there was a train in the station. In 1917, Carl Albert West was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Third Rail
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third rail systems are usually supplied from direct current electricity. Modern tram systems, street-running, avoid the risk of electrocution by the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge railways. Description Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") fo ...

Insulated-gate Bipolar Transistor
An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch, which, as it was developed, came to combine high efficiency and fast switching. It consists of four alternating layers (P–N–P–N) that are controlled by a metal–oxide–semiconductor (MOS) gate structure. Although the structure of the IGBT is topologically the same as a thyristor with a "MOS" gate ( MOS-gate thyristor), the thyristor action is completely suppressed, and only the transistor action is permitted in the entire device operation range. It is used in switching power supplies in high-power applications: variable-frequency drives (VFDs), electric cars, trains, variable-speed refrigerators, lamp ballasts, arc-welding machines, induction hobs, and air conditioners. Since it is designed to turn on and off rapidly, the IGBT can synthesize complex waveforms with pulse-width modulation and low-pass filters, so it is also used in switching ...

Electric Motor
An electric motor is an Electric machine, electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a Electromagnetic coil, wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, Inverter (electrical), inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be Brushed motor, brushed or Brushless motor, brushless, single-phase, Two-phase electric power, two-p ...

Induction Motor
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable and economical. Single-phase induction motors are used extensively for smaller loads, such as household appliances like fans. Although traditionally used in fixed-speed service, induction motors are increasingly being used with variable-frequency drives (VFD) in variable-speed service. VFDs offer especially important energy savings opportunities for existing and prospective induction motors in variable-torque centrifugal fan, pump and compressor load applications. Squirrel ...

Three-phase
Three-phase electric power (abbreviated 3φ) is a common type of alternating current used in electricity generation, Electric power transmission, transmission, and Electric power distribution, distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by multiple people. Three-phase power works by the voltage and currents being 120 degrees phase shift, out of phase on the three wires. As an AC system it allows the voltages to be easily stepped up using transformers to high voltage for transmission, and back down for distribution, giving high efficiency. A three-wire three-phase circuit is usually more economical than an equivalent two-wire Single-phase electric power, single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a giv ...
