Line 4 (São Paulo Metro)
Line 4 (Yellow) ( pt, Linha 4–Amarela) is one of the six lines that make up the São Paulo Metro and one of the thirteen lines that make up the São Paulo Metropolitan Rail Transportation Network. Originally called Southeast-Southwest Line, the line goes from Vila Sônia to Luz and currently has 11 stations along its and transports around 800,000 users/day. It is one of the most modern subway lines in Latin America and the first line in the region to utilize driverless trains and platform screen doors in all stations. Due to fiscal constraints, the construction of the line was divided into two phases: The phase one was completed in 2011 and the phase two was partially inaugurated between 2014 and 2018 and was fully completed by 2021. Now completed, Line 4 - Yellow goes from Vila Sônia to Luz station, in a long stretch. It was expected that the line would be fully completed by 2014. However, the deadline has been repeatedly pushed back and completion was only completed on 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
São Paulo Metro
The São Paulo Metro ( pt, Metrô de São Paulo, ), commonly called the ''Metrô'' () is one of the urban railways that serves the city of São Paulo, alongside the São Paulo Metropolitan Trains Company (CPTM), forming the largest metropolitan rail transport network of Latin America. The six lines in the metro system operate on of route, serving 91 stations. The metro system carries about 5,300,000 passengers a day. Metro itself is far from covering the entire urban area in the city of São Paulo and only runs within the city limits. However, it is complemented by a network of metropolitan trains operated by CPTM and Via Mobilidade, which serve the São Paulo and the São Paulo Metropolitan Region. The two systems combined form a long network. The metropolitan trains differs from Metro because it also serves other municipalities around São Paulo with larger average distance between stations and freight trains operating in some lines (except for the Line 9, which has almos ...

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) that operate on an exclusive 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 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 and platform. They are typically integrated with other public tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volt
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 = \fra ...

Direct 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 ...

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current colle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
