British Rail Class 710
The British Rail Class 710 ''Aventra'' is a type of electric multiple unit passenger train built by Bombardier Transportation for use on the London Overground network. The trains are part of Bombardier's Bombardier Aventra, Aventra family. The contract to provide 45 four-car trains was awarded in July 2015 and the trains were originally due to enter service in May 2018, although introduction was delayed until May 2019. History Background and specifications In 2012, Transport for London announced its intention to procure a fleet of new, longer DMUs, as the units then in service were unable to handle the passenger demand, causing overcrowding throughout the day. TfL issued a tender for manufacturers to supply eight three- or four-car trains. However, this proposal was subsequently shelved when the Government announced in June 2013 that the Gospel Oak to Barking line would be electrified, with proposals instead to purchase a fleet of new EMUs. TfL invited expressions of inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Contact Shoe
Electric current collectors are used by trolleybuses, trams, electric locomotives or EMUs to carry electrical power from overhead lines, electrical third rails, or ground-level power supplies to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for rails are mounted on the bogies. Typically, electric current connectors have one or more spring-loaded arms that press a collector or contact shoe against the rail or overhead wire. As the vehicle moves, the contact shoe slides along the wire or rail to draw the electricity needed to run the vehicle's motor. The current collector arms are electrically conductive but mounted insulated on the vehicle's roof, side or base. An insulated cable connects the collector with the switch, transformer or motor. The steel rails of the tracks act as the electrical return. Electric vehicles that collect their current from an overhead line system use different forms of one- or two-arm pantograph ...

Aventra
The Alstom Aventra (sold as the Bombardier Aventra until 2021) is a family of electric multiple unit (EMU) passenger trains produced in the United Kingdom originally by Bombardier Transportation and later by Alstom, as a successor to the Bombardier Electrostar. It incorporates a large proportion of its design from the latter family, while also including numerous new technologies and achieving compliance with more stringent requirements and operator demands. Bombardier began developing the Aventra in 2009 based on feedback from train operating companies (TOCs) and upcoming regulation changes. It has been designed to provide a generic platform for conducting inter-regional, commuter, metro, and high-speed passenger services. It has been claimed to be more efficient and flexible than the Electrostar, which was mainly achieved via the greater use of digital technology. The first order for the Aventra came from the Crossrail programme. Numerous other operators have since ordered the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

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 point ... [...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 throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
