British Rail Class 801
The British Rail Class 801 ''Azuma'' is a type of electric multiple unit (EMU) built by Hitachi Rail for London North Eastern Railway. The units have been built since 2017 at Hitachi Newton Aycliffe, Hitachi's Newton Aycliffe Manufacturing Facility and have been used on services on the East Coast Main Line since 16 September 2019. As part of its production, the Class 801 units were ordered as part of the Intercity Express Programme and are in the Hitachi A-train, Hitachi AT300 product family, alongside the closely related British Rail Class 800, Class 800 units. LNER have branded the units as the ''Azuma'', just like on their Class 800 units. Background and design As part of the UK Government's Intercity Express Programme, the Class 801 units were to be built as replacements for the InterCity 125 and InterCity 225 sets which were the main trains used for services on the Great Western Main Line (GWML) and the East Coast Main Line (ECML) at the time. Differing from the Class 800 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London North Eastern Railway
London North Eastern Railway (LNER) is a British train operating company. It is owned by the DfT OLR Holdings for the Department for Transport (DfT). The company's name echoes that of the London and North Eastern Railway, one of the Big Four companies which operated between 1923 and 1948. During June 2018, LNER took over the InterCity East Coast franchise, after the previous privately owned operator Virgin Trains East Coast (VTEC) returned it to the government following sustained financial difficulties. The DfT intended for the company to operate the franchise until a new public–private partnership could be established during 2020. However, in July 2019, it was announced that LNER had been given a direct-award to run these services beyond 28 June 2020, up until 2025, making it the longest franchise on the East Coast Main Line since Great North Eastern Railway (GNER). Early on, the integration of Great Northern services into LNER's operation after the expiration of the T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbo-diesel
The term turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler. Turbocharging of diesel engines began in the 1920s with large marine and stationary engines. Trucks became available with turbo-diesel engines in the mid-1950s, followed by passenger cars in the late 1970s. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping. Principle Diesel engines are typically well suited to turbocharging due to two factors: * A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture. ...

Railnews
''Railnews'' is a national monthly newspaper and news website for the British railway network. Content ''Railnews'' concentrates on issues important to employees of the railway industry, such as investment, careers, changes to industry structure, and political developments, as well as industrial relations and other trade union matters. It also maintains a focus on the people of the rail industry, rather than the companies alone. As a trade title covering the modern industry, it is not designed for railway enthusiasts or the heritage railway market. The ethos of ''Railnews'' is to be "dispassionate, objective and accurate". Following this, ''Railnews'' never carries unmarked advertorials, although much of its advertising revenue does come from major rail firms and franchise operators. History ''Railnews ''was originally the house newspaper of British Railways, published by the British Railways Board. It first appeared in 1963 under the editorship of Keith Horrox with a pric ...

Great Western Main Line
The Great Western Main Line (GWML) is a main line railway in England that runs westwards from London Paddington to . It connects to other main lines such as those from Reading to Penzance and Swindon to Swansea. Opened in 1841, it was the original route of the first Great Western Railway which was merged into the Western Region of British Railways in 1948. It is now a part of the national rail system managed by Network Rail with the majority of passenger services provided by the current Great Western Railway franchise. The line has recently been electrified along most of its length. The eastern section from Paddington to was electrified in 1998. Work to electrify the remainder of the route started in 2011 with an initial aim to complete the work all the way to Bristol by 2016, but in that year the section through Bath to Bristol Temple Meads was deferred with no date set for completion because costs had tripled.

British Rail Class 800
The British Rail Class 800 ''Intercity Express Train'' or ''Azuma'' is a type of bi-mode multiple unit train built by Hitachi Rail for Great Western Railway and London North Eastern Railway. The type uses electric motors powered from overhead electric wires for traction, but also has diesel generators to enable trains to operate on unelectrified track. It is a part of the Hitachi AT300 product family. The Class 800 was produced under the Intercity Express Programme (IEP) as a replacement for the Intercity 125 and Intercity 225 fleets of high speed trains. The trains were manufactured by Hitachi between 2014 and 2018, assembly being performed at the Hitachi Newton Aycliffe facility, alongside the related Class 801, from bodyshells shipped from the Kasado plant in Japan; no body construction takes place in the UK. As well as resembling the Class 801, the units are also very similar to the Class 802 units, which have uprated diesel engines and larger fuel tanks. The respectiv ...

Intercity Express Programme
The Intercity Express Programme (IEP) is an initiative of the Department for Transport (DfT) in the United Kingdom to procure new trains to replace the InterCity 125 and InterCity 225 fleets on the East Coast Main Line and Great Western Main Line. These new trains would be built by Hitachi as part of their A-train family, classified as Class 800 electro-diesel units and Class 801 electric multiple units. Hitachi designated the units as the AT300 family, which is their Intercity High Speed fleet. Other AT300 units have also been ordered for other train operating companies, which are not part of the IEP. History Formation It was first announced on 12 February 2009 by the DfT that Agility Trains (a consortium led by Hitachi) was the preferred bidder for the IEP, with the fleet initially being named as ''Hitachi Super Express''. The final decision on the award of contract, and its value and composition, originally expected by early 2009, was delayed by several years: a delay ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ex ...

Train Protection & Warning System
The Train Protection & Warning System (TPWS) is a train protection system used throughout the British passenger main-line railway network, and in Victoria, Australia. The British Rail Safety and Standards Board's definition is: The purpose of TPWS is to stop a train by automatically initiating a brake demand, where TPWS track equipment is fitted, if the train has: *passed a signal at danger without authority *approached a signal at danger too fast *approached a reduction in permissible speed too fast *approached buffer stops too fast. TPWS is not designed to prevent SPADs but to mitigate the consequences of a SPAD, by preventing a train that has had a SPAD from reaching a conflict point after the signal. A standard installation consists of an on-track transmitter adjacent to a signal, activated when the signal is at danger. A train that passes the signal will have its emergency brake activated. If the train is travelling at speed, this may be too late to stop it before the poin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Train Control System
The European Train Control System (ETCS) is the signalling and control component of the European Rail Traffic Management System (ERTMS). It is a replacement for legacy train protection systems and designed to replace the many incompatible safety systems currently used by European railways. The standard was also adopted outside Europe and is an option for worldwide application. In technical terms it is a type of positive train control (PTC). ETCS is implemented with standard trackside equipment and unified controlling equipment within the train cab. In its advanced form, all lineside information is passed to the driver wirelessly inside the cab, removing the need for lineside signals watched by the driver. This will give the foundation for a later to be defined automatic train operation. Trackside equipment aims to exchange information with the vehicle for safely supervising train circulation. The information exchanged between track and trains can be either continuous or i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Warning System
The Automatic Warning System (AWS) was introduced in the 1950s in the United Kingdom to provide a train driver with an audible warning and visual reminder that they were approaching a distant signal at caution. Its operation was later extended to give warnings for; * A colour light signal displaying a double yellow (steady or flashing), single yellow or red aspect * A reduction in permissible speed * A temporary or emergency speed restriction * An automatic barrier crossing locally monitored (ABCL), an automatic open crossing locally monitored (AOCL), or an open crossing (OC). AWS was based on a 1930 system developed by Alfred Ernest Hudd and marketed as the "Strowger-Hudd" system. An earlier contact system, installed on the Great Western Railway since 1906 and known as automatic train control (ATC), was gradually supplanted by AWS within the Western Region of British Railways. Principles of operation Information is conveyed by magnetic fields to the moving train thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
