British Rail Class 92
The British Rail Class 92 is a dual-voltage electric locomotive, which can run on 25 kV AC from overhead wires or 750 V DC from a third rail. It was designed specifically to operate services through the Channel Tunnel between Great Britain and France. Eurotunnel indicates the Class 92 locomotive as the reference for other locomotives which railway undertakings might want to get certified for usage in the Channel tunnel. Locomotives of this type are operated by GB Railfreight/Europorte 2 and DB Cargo UK. In France, a number were also owned and operated by SNCF; these were classified as CC 92000 on French railways. The Class 92 was intended as a mixed-traffic locomotive both for hauling international freight trains and the ill-fated, never introduced ''Nightstar'' passenger sleeper trains though the Channel Tunnel. Since introduction, the fleet was exclusively allocated to freight; however, in March 2015, six locomotives owned by GB Railfreight have begun passenger operation ...

Caledonian Sleeper
''Caledonian Sleeper'' is the collective name for overnight sleeper train services between London and Scotland, in the United Kingdom. It is one of only two currently operating sleeper services on the railway in the United Kingdom, the other being the ''Night Riviera'' which runs between London and Penzance. A sleeper service has been run along the West Coast Main Line since 24 February 1873. Sleepers were historically run on the rival East Coast Main Line as well; however, all remaining sleeper services that ran on the east coast routes were withdrawn in May 1988. While InterCity continued to operate what would later become known as the ''Caledonian Sleeper'', it decided to remove all seating accommodation on its remaining sleeper services during the mid-1990s. The Anglo-Scottish sleeper services were transferred to ScotRail on 5 March 1995; as a consequence of the privatisation of British Rail, on 31 March 1997, the service was privatised as a part of the wider ScotRail fr ...

Transmission Voie-Machine
Transmission Voie-Machine (TVM, English: track-to-train transmission) is a form of in-cab signalling originally deployed in France and is mainly used on high-speed railway lines. TVM-300 was the first version, followed by TVM-430. TVM-300 was developed in the 1970s as part of the TGV project. At speeds faster than 220 kilometres per hour, TGV trains only run along dedicated tracks designated as (LGV). When travelling at high speed, it is not possible for the driver to accurately see colour-light railway signals at the side of the track. Signalling information is instead transmitted to the train and displayed on the train driver's dashboard. The driver is shown the safe operating speed, measured in kilometres per hour. The 1980s-developed TVM-430 system provides more information than traditional signalling systems would allow, including track gradient profiles and information about the state of signalling blocks further ahead. This high degree of automation does not remove the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurotunnel
Getlink, formerly Groupe Eurotunnel, is a European public company based in Paris that manages and operates the infrastructure of the Channel Tunnel between England and France, operates the Eurotunnel Shuttle train service, and earns revenue on other trains that operate through the tunnel (Eurostar passenger and DB Schenker freight). Groupe Eurotunnel was established on 13 August 1986 to finance, build, and operate the Channel Tunnel under a concession granted by the French and British governments. The tunnel was constructed between 1988 and 1994 by TransManche Link (TML) under a contract issued by Groupe Eurotunnel; construction costs would overrun considerably, from TML's original estimate of £4.7 billion to the final cost of £9.5 billion. On 6 May 1994, the completed tunnel was officially opened. Its rail infrastructure comprises of double track railway in the main tunnels, plus extensive surface-level terminal facilities at Folkestone in England and Calais in Fr ...

Channel Tunnel
The Channel Tunnel (french: Tunnel sous la Manche), also known as the Chunnel, is a railway tunnel that connects Folkestone (Kent, England, UK) with Coquelles ( Hauts-de-France, France) beneath the English Channel at the Strait of Dover. It is the only fixed link between the island of Great Britain and the European mainland. At its lowest point, it is deep below the sea bed and below sea level. At , it has the longest underwater section of any tunnel in the world, and is the third longest railway tunnel in the world. The speed limit for trains through the tunnel is . The tunnel is owned and operated by the company Getlink, formerly "Groupe Eurotunnel". The tunnel carries high-speed Eurostar passenger trains, the Eurotunnel Shuttle for road vehicles and international freight trains. It connects end-to-end with the high-speed railway lines of the LGV Nord in France and High Speed 1 in England. In 2017, through rail services carried 10.3 million passengers and 1.22 milli ...

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 ...

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 ...

Overhead Wires
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 are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of re ...

Railfreight Distribution
Railfreight Distribution was a sub-sector of British Rail, created by the division in 1987 of British Rail's previous Railfreight sector. It was responsible for non-trainload freight operations, as well as Freightliner and Intermodal services. In its early years, the division was occasionally referred to as Speedlink Distribution. It was later responsible for freight operations through the Channel Tunnel. History In the 1980s, freight traffic on the railway was in decline, due to a mixture of increased competition from road transport, a shrinking network that had reduced rail's reach and a decline in the domestic manufacturing industry, reducing internal demands for raw materials and transport of finished product for export. By the late 1980s, British Rail In October 1988, took three troublesome divisions of their freight operations; Speedlink (wagonload), Freightliner (Container), Railfreight International (International traffic) and merged them into one entity, Railfreight ...

British Rail
British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most of the overground rail transport in Great Britain from 1948 to 1997. It was formed from the nationalisation of the Big Four British railway companies, and was privatised in stages between 1994 and 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in January 1963, when it was formally renamed the British Railways Board. The period of nationalisation saw sweeping changes in the railway. A process of dieselisation and electrification took place, and by 1968 steam locomotives had been entirely replaced by diesel and electric traction, except for the Vale of Rheidol Railway (a narrow-gauge tourist line). Passengers replaced freight as the main source of business, and one-third of the network was closed by the Beeching cuts of the 1960s in an effort to reduce rail subsidies. On privatis ...
