Meridian (train)
The British Rail Class 222 ''Meridian'' is a group of 5- or 7- car diesel-electric multiple-unit high-speed passenger train capable of . Twenty-seven sets were built by Bombardier Transportation in Bruges, Belgium. The Class 222 is part of the Bombardier Voyager family, so it is very similar to the and trains used by CrossCountry and Grand Central. In comparison, the Class 222s have a different interior and also have more components fitted under the floors to free up space within the body. Built for Midland Mainline and Hull Trains, today all are operated by East Midlands Railway and are branded as the ''Meridians''. All 5- and 7-car sets were converted to their present state from cars from the past 4- and 9-car sets. Details All are equipped with a Cummins QSK19 diesel engine of at 1,800rpm. This powers a generator, which supplies current to motors driving two axles per coach. Approximately can be travelled between each refuelling. Class 222 have rheostatic braking u ...

East Midlands Railway
East Midlands Railway (EMR; legally Transport UK East Midlands Limited) is a British train operating company owned by Transport UK Group, and is the current operator of the East Midlands franchise. Originally owned by Abellio (transport company), Abellio, EMR took over operations from East Midlands Trains (EMT) on 18 August 2019, on an agreement to run the franchise for eight years. As part of the franchise commitments, EMR placed an order for 33 new bi-mode British Rail Class 810, Class 810 ''Aurora'' high speed train sets, and sourced over 40 pre-existing British Rail Class 170, Class 170 ''Turbostar'' diesel multiple units from other operators. During early 2020, passenger numbers and ticket revenues collapsed following the onset of the COVID-19 pandemic, leading to the original franchise agreement being initially suspended before being replaced entirely. Under the new National Rail Contract signed in 2022, the franchise is to last until October 2030. In February 2023, Trans ...

Automatic Warning System
Automatic Warning System (AWS) is a railway safety system invented and predominantly used in the United Kingdom. It provides a train driver with an audible indication of whether the next Railway_signal, signal they are approaching is clear or at caution. Depending on the upcoming signal state, the AWS will either produce a 'horn' sound (as a warning indication), or a 'bell' sound (as a clear indication). If the train driver fails to acknowledge a warning indication, an emergency brake application is initiated by the AWS; if the driver correctly acknowledges the warning indication, by pressing an acknowledgement button, then a visual 'sunflower' is displayed to the driver, as a reminder of the warning. Principles of operation AWS is a system based on trains detecting magnetic fields. These magnetic fields are created by permanent magnets and electromagnets installed on the track. The polarity and sequence of magnetic fields detected by a train determine the type of indication ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Coupling
A coupling or coupler is a mechanism, typically located at each end of a rolling stock, rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train. Throughout the history of rail vehicles, a variety of coupler designs and types have been developed worldwide. Key design considerations include strength, reliability, easy and efficient handling, and operator safety. Automatic couplers engage automatically when the cars are pushed together. Modern versions not only provide a mechanical connection, but can also couple brake lines and data lines. Different countries use different types of couplers. While North American railroads and China use Janney couplers, railroads in the former Soviet Union use SA3 couplers and the European countries use Scharfenberg coupler, Scharfenberg and Buffers and chain coupler, screw ...

Rheostatic Braking
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an electrical c ...

Electric Current
An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface. The moving particles are called charge carriers, which may be one of several types of particles, depending on the Electrical conductor, conductor. In electric circuits the charge carriers are often electrons moving through a wire. In semiconductors they can be electrons or Electron hole, holes. In an Electrolyte#Electrochemistry, electrolyte the charge carriers are ions, while in Plasma (physics), plasma, an Ionization, ionized gas, they are ions and electrons. In the International System of Units (SI), electric current is expressed in Unit of measurement, units of ampere (sometimes called an "amp", symbol A), which is equivalent to one coulomb per second. The ampere is an SI base unit and electric current is a ISQ base quantity, base quantity in the International System of Qua ...

Electrical Generator
In electricity generation, a generator, also called an ''electric generator'', ''electrical generator'', and ''electromagnetic generator'' is an electromechanical device that converts mechanical energy to electrical energy for use in an external circuit. In most generators which are rotating machines, a source of kinetic power rotates the generator's shaft, and the generator produces an electric current at its output terminals which flows through an external circuit, powering electrical loads. Sources of mechanical energy used to drive generators include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. Generators produce nearly all of the electric power for worldwide electric power grids. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

222008 First Class Interior
8 (eight) is the natural number following 7 and preceding 9. Etymology English ''eight'', from Old English '', æhta'', Proto-Germanic ''*ahto'' is a direct continuation of Proto-Indo-European '' *oḱtṓ(w)-'', and as such cognate with Greek and Latin , both of which stems are reflected by the English prefix oct(o)-, as in the ordinal adjective ''octaval'' or ''octavary'', the distributive adjective is ''octonary''. The adjective ''octuple'' (Latin ) may also be used as a noun, meaning "a set of eight items"; the diminutive ''octuplet'' is mostly used to refer to eight siblings delivered in one birth. The Semitic numeral is based on a root ''*θmn-'', whence Akkadian ''smn-'', Arabic ''ṯmn-'', Hebrew ''šmn-'' etc. The Chinese numeral, written (Mandarin: ''bā''; Cantonese: ''baat''), is from Old Chinese ''*priāt-'', ultimately from Sino-Tibetan ''b-r-gyat'' or ''b-g-ryat'' which also yielded Tibetan '' brgyat''. It has been argued that, as the cardinal num ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CrossCountry
CrossCountry (legal name XC Trains Limited) is a British train operating company owned by Arriva UK Trains, operating the current CrossCountry franchise. The CrossCountry franchise was restructured by the Department for Transport (DfT) in 2006, incorporating elements of both the Central Trains and the Virgin CrossCountry franchises, ahead of its invitation to tender on October of that year. On 10 July 2007, the DfT announced that Arriva had been awarded the New Cross Country franchise. CrossCountry is one of only two franchised train operating companies that does not manage any stations, the other being Caledonian Sleeper. CrossCountry's services have been periodically disrupted by industrial action amongst its staff, often due to disputes over rostering and pay. While the franchise had been originally due to conclude on 31 March 2016, multiple subsequent agreements have been enacted; in September 2023, the DfT confirmed that the franchise has been extended for a further four yea ...

High-speed Rail
High-speed rail (HSR) is a type of rail transport network utilising trains that run significantly faster than those of traditional rail, using an integrated system of specialised rolling stock and dedicated railway track, tracks. While there is no single definition or standard that applies worldwide, lines built to handle speeds of at least or upgraded lines of at least are generally considered to be high-speed. The first high-speed rail system, the Tōkaidō Shinkansen, began operations in Honshu, Japan, in 1964. Due to the streamlined spitzer (bullet), spitzer-shaped nose cone of the 0 Series Shinkansen, trains, the system also became known by its English nickname bullet train. Japan's example was followed by several European countries, initially in High-speed rail in Italy, Italy with the Florence–Rome high-speed railway, Direttissima line, followed shortly thereafter by High-speed rail in France, France, High-speed rail in Germany, Germany, and High-speed rail in Spain, ...
