British Rail Class 707
The British Rail Class 707 ''Desiro City'' is an electric multiple unit passenger train. Siemens Mobility built 30 five-carriage sets. Initially leased by South West Trains, its franchise successor South Western Railway began phasing them out of their network. Since September 2021, 18 have entered service with Southeastern. The remaining 12 will be transferred to Southeastern in 2023. Background In September 2014, South West Trains (SWT) announced plans to procure 30 five-car trains to expand its fleet to take advantage of significant infrastructure improvements that would allow the operation of ten-car trains. The Class 707 was the second product purchased for use on the British network from the ''Desiro City'' range, following the purchase of the Class 700 for Thameslink. All are leased from rolling stock company (ROSCO) Angel Trains. Construction of the first vehicles began in June 2015, with the first completed in March 2016. The first two were completed as dual-voltage u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 sup ...

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, second, s, and ampere, 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 = \tex ...

Peterborough Railway Station
Peterborough railway station serves the city of Peterborough, Cambridgeshire, England. It is down the East Coast Main Line from . The station is a major interchange serving both the north–south ECML, as well as long-distance and local east–west services. The station is managed by London North Eastern Railway. Ticket gates came into use at the station in 2012. History There have been a number of railway stations in Peterborough: Peterborough East (1845–1966), the current station which opened in 1850 (previously known by various names including Peterborough North); and briefly Peterborough Crescent (1858–1866). Peterborough was the site of the first mast to be installed as part of the ECML electrification project, which is located behind platform 1. Openings Peterborough East opened on 2 June 1845 along with the Ely to Peterborough Line built by Eastern Counties Railway (ECR) and the Northampton and Peterborough Railway built by the London and Birmingham Railwa ...

East Coast Main Line
The East Coast Main Line (ECML) is a electrified railway between London and Edinburgh via Peterborough, Doncaster, York, Darlington, Durham and Newcastle. The line is a key transport artery on the eastern side of Great Britain running broadly parallel to the A1 road. The line was built during the 1840s by three railway companies, the North British Railway, the North Eastern Railway, and the Great Northern Railway. In 1923, the Railway Act of 1921 led to their amalgamation to form the London and North Eastern Railway (LNER) and the line became its primary route. The LNER competed with the London, Midland and Scottish Railway (LMS) for long-distance passenger traffic between London and Scotland. The LNER's chief engineer Sir Nigel Gresley designed iconic Pacific steam locomotives, including '' Flying Scotsman'' and '' Mallard'' which achieved a world record speed for a steam locomotive, on the Grantham-to-Peterborough section. In 1948, the railways were nationalise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wegberg-Wildenrath Test And Validation Centre
The Wegberg-Wildenrath Test and Validation Centre (german: Prüf- und Validationscenter Wegberg-Wildenrath) is a railway test centre owned by Siemens near Wildenrath in North Rhine-Westphalia, Germany. History The centre is located on the site of the former RAF Wildenrath British military airfield. After the airfield closed in 1992, it was taken over by Siemens who opened the test and validation centre in June 1997. It had five tracks over . By 2007, the railway test tracks had taken over considerable areas of the airfield, with all but the western threshold and overrun of the runway obliterated. The north-east dispersal is completely taken over by sidings, workshops and loops. Of the southern dispersals, the central and eastern are bisected by the main railway oval test track. There are ovals of track for testing trains, and various electrification systems. The test track is connected to the rest of the German railway network by the German portion of the Iron Rhine freight railw ...

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 collectors ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantograph (transport)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...

Govia Thameslink Railway
Govia Thameslink Railway (GTR) is a train operating company that operates the Thameslink, Southern and Great Northern (TSGN) rail franchise in England. Within the franchise, GTR runs the Thameslink, Great Northern, Southern (Govia Thameslink Railway), Southern and Gatwick Express services. GTR is a subsidiary of Govia, which is itself a joint venture between the British Go-Ahead Group (65%) and French company Keolis (35%). The franchise was awarded, after repeated delays, to Govia Thameslink Railway on 23 May 2014. On 14 September 2014, GTR took over operations for the prior franchisee First Capital Connect; during July 2015, both Southern and Gatwick Express operations were integrated into GTR. This change made it the largest rail franchise in terms of passengers, staff and fleet in the UK. The franchise has an unusual structure involving a management contract that sees all fare revenues going straight to the Department for Transport (DfT), which in turn pays GTR fixed amou ...

British Rail Class 700
The British Rail Class 700 ''Desiro City'' is an electric multiple unit passenger train capable of operating on from overhead wires or 750 V DC from third rail. 115 trainsets were built between 2014 and 2018, for use on the Thameslink network, as part of the Thameslink Programme in the United Kingdom. , they are operated by Govia Thameslink Railway. In 2011, the consortium Cross London Trains (XLT) consisting of Siemens Project Ventures, 3i Infrastructure, and Innisfree was announced as preferred bidder with Siemens Mobility to manufacture the trains. The decision was politically controversial as the trains were to be built in Germany, while the competing consortium led by Bombardier Transportation had a UK train factory. Both the procurement process and final close of contract were significantly delayed, resulting in the expected first delivery date moving from 2012 to 2016. The £1.6 billion contract to manufacture and provide service depots for the trains was fina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
