Indian Locomotive Class WAG-1
The Indian locomotive class WAG-1 is a class of 25 kV AC electric locomotives that was imported from Europe in 1960s for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods traffic (G) engine, 1st (1). A total of 112 WAG-1 locomotives were built by The European Group 50 Hz Group/European Group/50 Cycles Group (consortium) between 1963 and 1966. They entered service in 1964. The WAG-1 served both passenger and freight trains for over 40 years. As of January 2002, All locomotives have been removed from service all but one were scrapped. History Forty-two locomotives of this type were ordered from European Group. Five of these were completely assembled in Europe and the remaining were built at CLW. A repeat order was placed on for 20 locomotives in 1963. Further these locomotives were manufactured at CLW. The typical feature of these locomotive is the Monomotor bogies. This construction results in substantial saving in weight in traction equi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Rail Museum, New Delhi
The National Rail Museum in Chanakyapuri, New Delhi, displays exhibits on the history of rail transport in India. The museum was inaugurated on 1 February 1977. The museum spans over an area of over 11 acres and the indoor gallery comprises an octagonal building which houses six display galleries and a large open area is laid out to simulate the atmosphere of a railway yard. It is open every day except Mondays and national holidays. History A ''Transport Museum'' was first proposed in 1962, under the advice of rail enthusiast Michael Graham Satow. The proposal took a concrete shape in 1970 and on 7 October 1971 the foundation stone was laid at the museum's present site in Chanakyapuri, New Delhi, by the then-President of India, V. V. Giri. The museum was inaugurated as the ''Rail Transport Museum'' in 1977 by Kamalapati Tripathi, the minister for public transportation. The museum was originally intended to be a part of a larger museum that covered the history of rai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.

Railway Locomotives Introduced In 1964
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Locomotives Of India
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of posit ...

Locomotives Of India
The Indian Railways primarily operates fleet of electric and diesel locomotives, along with several compressed natural gas (CNG) locomotives. Steam locomotives are operated on a few World Heritage Sites and also run occasionally as heritage trains. A locomotive is also known as a loco or more popularly as an engine. The country's first steam locomotive ran on the Red Hill Railway (built by Arthur Cotton to transport granite for road-building) from Red Hills to the Chintadripet bridge in Madras in 1837. Classification Locomotives were classified by track gauge, motive power, function and power (or model number) in a four- or five-letter code. The first letter denotes the track gauge. The second letter denotes motive power (diesel or electric), and the third letter denotes use (goods, passenger, mixed or shunting). The fourth letter denotes a locomotive's chronological model number. In 2002, a new classification system was adopted. For newer diesel locomotives, the four ...

Rail Transport In India
Rail transport in India is an important mode of conveyance for people and goods in India. Indian Railways (IR) is the primary operator of rail operations throughout the country. IR is a state-owned organisation of the Ministry of Railways, which historically had its own government budget. Between 2019 and 2020, 22.15 million passengers used the Indian Railways network daily. In the same period, 3.32 million metric tons of freight was also shipped daily on the IR network. Other locally owned public corporations operate various suburban and urban railways throughout the country, such as Chennai Metro and the trams in Kolkata. Private sector operations currently exist only for freight trains and railroads, exclusively for non-passenger usage, but there were renewed efforts in 2020 to encourage private sector involvement in the running of passenger trains. In March 2020, the national rail network comprised of track over a route of and 7,325 stations. India's natio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...

Société Anonyme Des Ateliers De Sécheron
The (SAAS, in English translated as ''"Anonymous Society of Sécheron Workshops"'') was a joint-stock company based in Geneva, Switzerland. It specialized in electrical engineering, including the manufacture of electrical equipment and locomotives. In 1989, the company was split into four successor companies, ABB Sécheron SA, ABB Power Generation (closed in 1995), ABB Systèmes de Transport and Sécheron SA. History In 1879, Alfred de Meuron set up a small workshop in Geneva to manufacture electrical appliances. This workshop ultimately formed the basis for the establishment of SAAS on 9 July 1918. The following year, 1919, Brown Boveri & Cie (BBC) became SAAS's main shareholder. Five years later, SAAS resumed its independence. The company remained independent until 1969, when competitive pressures forced it to seek new partners. In 1970, BBC took over as sole shareholder. However, the company's name was changed only in 1982, when it became BBC Sécheron SA. In 1988, B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rectifier
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The reverse operation (converting DC to AC) is performed by an Power inverter, inverter. The process is known as ''rectification'', since it "straightens" the direction of current. Physically, rectifiers take a number of forms, including Vacuum tube#Diodes, vacuum tube diodes, wet chemical cells, mercury-arc valves, stacks of copper and selenium rectifier, selenium oxide plates, Diode#Semiconductor diodes, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches. Historically, even synchronous electromechanical switches and motor-generator sets have been used. Early radio receivers, called crystal radios, used a "Cat's-whisker detector, cat's whisker" of fine wire pressing on a crystal of galena (lead sulfide) to serve as a point-contact rectifier or "crystal detec ...

Transformer
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits. Since the invention of the first constant-potential transfo ...
