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, having been in service for over 50 years. It was the only stock to have luggage racks, umbrella hooks and separate power and braking controls, and the last stock not to feature 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 electrifi ...

Cravens
Cravens Railway Carriage and Wagon Company Limited was a railway rolling stock builder in the Darnall district of Sheffield, England. Founded by brothers named Craven and known as Craven Brothers, later Cravens Limited, it remained a family business until John Brown & Company acquired a controlling shareholding in 1919. Its name was changed back to Cravens Limited in 1954 when it finally became a wholly owned subsidiary of John Brown. Ownership Craven Brothers was a British engineering firm started in 1853 by brothers William and John Craven that built large machine tools for railway and engineering workshops and later workshop and railway cranes. Two Sheffield-raised Craven brothers, sons of a Wakefield mason and builders themselves began to make railway wagons in 1866 when railway companies also pulled wagons, particularly purpose-built wagons, for other owners. A third brother, previously an architect and timber merchant, soon joined them.Joseph Craven (–6 December 1900) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volt
The volt (symbol: V) is the unit of electric potential, Voltage#Galvani potential vs. electrochemical potential, electric potential difference (voltage), and electromotive force in the International System of Units, International System of Units (SI). Definition One volt is defined as the electric potential between two points of a electrical conductor, conducting wire when an electric current of one ampere dissipates one watt of power (physics), power between those points. It can be expressed in terms of SI base units (metre, m, kilogram, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac = \text\text^2\text^. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units (metre, m, kilogram, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac = \text\text^2\text^. It can also be expressed as amperes times ohms (curre ... [...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: * 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 (brand), 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 (politician), Herbert Morrison, who was Secretary of State for Transport, Transport Minister in the Second MacDonald ministry, 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 First National ministry, National Government. The new government, although dominated by Conservative Party (UK), Conservatives, decided to continue with the bill, with no serious changes, despite its extensive transfer of pri ...

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 t ...

London Overground
London Overground (also known simply as the Overground) is a Urban rail in the United Kingdom, suburban rail network serving London and its environs. Established in 2007 to take over Silverlink Metro routes, it now serves a large part of Greater London as well as Hertfordshire, with 113 stations on the six lines that make up the network. The Overground forms part of the United Kingdom's National Rail network but it is under the Rail franchising in Great Britain#Concessions, concession control and branding of Transport for London (TfL). Operation has been contracted to Arriva Rail London since 2016. TfL previously assigned orange as a mode-specific colour for the Overground in branding and publicity including the Roundel (London Transport), roundel, on the Tube map, trains and stations. In 2024, each of the six Overground lines were given distinct colours and names – Lioness line, Lioness, Mildmay line, Mildmay, Windrush line, Windrush, Weaver line, Weaver, Suffragette line, ...

Contact Shoe
A current collector (often called a "pickup") is a device used in trolleybuses, trams, electric locomotives and Electric multiple unit, EMUs to carry electric power (Electric current, current) from overhead lines, electric third rails, or ground-level power supply, 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 electrical conductivity, electrically conductive but mounted Electrical insulation, insulated on the vehicle's roof, side or base. An insulated cable connects the collector with the switch, transformer or Electric motor, motor. The Rail profile, stee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fourth Rail
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or Rail freight transport, freight in separate cars), electric multiple units (Passenger car (rail), passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient electric power station, generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and electric transmission line, transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous electrical conductor, conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel cei ...
