London Underground A60 Stock
The London Underground A60 and A62 Stock, commonly referred to as A Stock, was a type of sub-surface rolling stock which operated on the Metropolitan line of the London Underground from 12 June 1961 to 26 September 2012, and on the East London line from 1977 until 22 December 2007, when it closed to be converted into London Overground (except in 1986, when one-man operation conversion of the fleet took place). The stock was built in two batches (A60 and A62) by Cravens of Sheffield in the early 1960s, and replaced all other trains on the line. At the time of its withdrawal in September 2012, the stock was the oldest on the Underground. It was the only stock to have luggage racks, umbrella hooks and separate power and braking controls, and the last stock not to have any automated announcements. Development and introduction The design was formulated by W S Graff-Baker of the London Passenger Transport Board, as part of the electrification of the Metropolitan line from to Am ...

Metropolitan Line
The Metropolitan line, colloquially known as the Met, is a London Underground line between in the City of London and and in Buckinghamshire, with branches to in Hertfordshire and in Hillingdon. Printed in magenta on the tube map, the line is in length and serves 34 stations (9 of which are step free). Between Aldgate and , the track is mostly in shallow " cut and cover" tunnels, apart from short sections at and Farringdon stations. The rest of the line is above ground, with a loading gauge of a similar size to those on main lines. Just under passenger journeys were made on the line in 2011/12. The line is one of just two Underground lines to cross the Greater London boundary (the other being the Central line). It is the only Underground line with an express service at peak times; the resulting longer distance between stations means trains can achieve the system's highest speeds of over on some sections. In 1863, the Metropolitan Railway began the world's first unde ... [...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 ...

Circle Line (London Underground)
The Circle line is a spiral-shaped London Underground line, running from Hammersmith in the west to Edgware Road and then looping around central London back to Edgware Road. The railway is below ground in the central section and on the loop east of Paddington. Unlike London's deep-level lines, the Circle line tunnels are just below the surface and are of similar size to those on British main lines. Printed in yellow on the Tube map, the line serves 36 stations, including most of London's main line termini. Almost all of the route, and all the stations, are shared with one or more of the three other sub-surface lines, namely the District, Hammersmith & City and Metropolitan lines. On the Circle and Hammersmith & City lines combined, over 114 million passenger journeys were recorded in 2011/12. The first section became operational in 1863 when the Metropolitan Railway opened the world's first underground line between Paddington and with wooden carriages and steam loco ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Works Programme
The New Works Programme of 1935–1940 was the major investment programme delivered by the London Passenger Transport Board (LPTB), commonly known as London Transport, which had been created in 1933 to coordinate underground train, tram, trolleybus and bus services in the capital and the surrounding areas. The programme was to develop many aspects of the public transport services run by the LPTB and the suburban rail services of the Great Western Railway (GWR) and London and North Eastern Railway (LNER). The investment was largely backed by government assistance as well as by the issuing of financial bonds and was estimated to cost £42,286,000 in 1936LPTB submission to Parliament, (approximately £ today). London Underground The Programme saw major reconstructions of many central area Underground stations, with escalators being installed to replace lifts; extensions of several tube lines; and connection to and electrification of a number of suburban lines. These included: *Met ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amersham Station
Amersham is a London Underground and National Rail station in Amersham in the Chiltern district of Buckinghamshire, England. Amersham station is a terminus of the London Underground's Metropolitan line. It is 23.7 miles (38.1 km) northwest of Charing Cross, making it the second furthest Underground station from central London and the second most westerly station of the whole London Underground system, after . It is in Travelcard Zone 9 (previously zone D). Amersham station is also served by Chiltern Railways, which run trains between London Marylebone and Aylesbury. From Aylesbury a shuttle service to Princes Risborough provides access to through services between Marylebone and Birmingham Snow Hill. The journey times between Amersham and Central London range between 33 and 60 minutes. The journey time between Amersham and Chalfont & Latimer is about three and a half minutes. History The station was opened on 1 September 1892 as part of the Metropolitan Railway (M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Passenger Transport Board
The London Passenger Transport Board was the organisation responsible for local public transport in London and its environs from 1933 to 1948. In common with all London transport authorities from 1933 to 2000, the public name and brand was London Transport. History The London Passenger Transport Board (LPTB) was established pursuant to the London Passenger Transport Act 1933 enacted on 13 April 1933. The bill had been introduced by Herbert Morrison, who was Transport Minister in the Labour Government until 1931. Because the legislation was a hybrid bill it had been possible to allow it to 'roll over' into the new parliament under the incoming National Government. The new government, although dominated by Conservatives, decided to continue with the bill, with no serious changes, despite its extensive transfer of private undertakings into the public sector. On 1 July 1933, the LPTB came into being, covering the "London Passenger Transport Area". The LPTB's financial struct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

One-man Operation
One-person operation (OPO), also known as driver-only operation (DOO), one-man operation (OMO), single person train operation (SPTO), or one-person train operation (OPTO), similarly to Driver Controlled Operation, is operation of a train, bus, or tram by the driver alone, without a conductor. On one-person operated passenger trains, the engineer must be able to see the whole train to make sure that all the doors are safe for departure. On curved platforms a CCTV system, mirror or station dispatch staff are required. Although extra infrastructure such as cameras and mirrors might require additional investment, one-person operation is usually faster and cheaper to implement than automatic train operation, requiring a smaller investment in, for example, platform intruder detection systems and track protection (fencing, bridge-caging, CCTV etc.). In some cases, one-person operation can be seen as an intermediate step towards automatic train operation. While European freight ...

London Overground
London Overground (also known simply as the Overground) is a suburban rail network serving London and its environs. Established in 2007 to take over Silverlink Metro routes, (via archive.org). it now serves a large part of Greater London as well as the home county of Hertfordshire, with 113 stations on nine different routes. The Overground forms part of the United Kingdom's National Rail network but it is under the concession control and branding of Transport for London. Operation has been contracted to Arriva Rail London since 2016. TfL assigned orange as a mode-specific colour for the Overground in branding and publicity including the roundel, on the Tube map, trains and stations. History Pre-1999 Rail services in Great Britain are mostly run under franchises operated by private train operating companies, marketed together as National Rail. The concept of developing a network of orbital services around London goes back to the independently produced Ringrail propos ...

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 pantogra ...
