Indian Locomotive Class YAM-1
Indian locomotive class YAM1 is the first, and so far only class of metre gauge (Y), Alternating Current (A), mixed traffic (M) electric locomotive in India. Twenty were built in 1964–66 by a Japanese consortium led by Mitsubushi. Background When the Madras (now Chennai) to Tambaram line was electrified in 1931, the 1500 V DC system was originally used. As part of an extension of the electrification to Villupuram in 1965, the whole section was converted to the 25 kV AC system. Eighteen YAM1 locomotives (later extended to 20) and YAU1 4-car electric multiple units were built for service on the network. Design The YAM1 locomotives were supplied by Mitsubishi in 1964–66 (four in 1964, 14 in 1965 and two in 1966). They were jointly built by Mitsubishi, Toshiba and Hitachi, as shown by their builders' plates. They are of the B-B configuration, with two monomotor bogies, each with one bogie-mounted DC traction motor; the two traction motors were permanently couple ...

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 ...

Metre Gauge Electric Locomotives
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path travelled by light in a vacuum in of a second. After the 2019 redefin ...

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] |
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] |
Indian Locomotive Class WAM-2/3
The Indian locomotive class WAM- 2/3 is a class of 25 kV AC electric locomotives that was imported from Japan in 1960s for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Mixed traffic (M) engine, 2nd (2). A total of 38 WAM-2/3 locomotives were built by The Japanese Group (a consortium of Mitsubishi, Hitachi and Toshiba) between 1960 and 1964. They entered service in 1960. The WAM-2/3 served both passenger and freight trains for over 40 years. As of January 2020, All locomotives have been removed from service all and were scrapped. History These locomotives were built by a consortium of Mitsubishi, Hitachi and Toshiba (The Japanese Group, as attested by a plaque fixed on their sides) as a second option to the Europeans WAM-1. They were delivered in 1960 and were a bit lower powered than the WAM1 but had similar Bo-Bo wheel arrangement (4 wheels per bogie) with four Mitsubishi DC traction motors connected to the wheels permanently in parallel thro ...

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 sup ...

Bo-Bo
B-B and Bo-Bo are the Association of American Railroads (AAR) and British classifications of wheel arrangement for railway locomotives with four axles in two individual bogies. They are equivalent to the B′B′ and Bo′Bo′ classifications in the UIC system. The arrangement of two, two-axled, bogies is a common wheel arrangement for modern electric and diesel locomotives. Bo-Bo Bo-Bo is the UIC indication of a wheel arrangement for railway vehicles with four axles in two individual bogies, all driven by their own traction motors. It is a common wheel arrangement for modern electric and diesel-electric locomotives, as well as power cars in electric multiple units. Most early electric locomotives shared commonalities with the steam engines of their time. These features included side rods and frame mounted driving axles with leading and trailing axles. The long rigid wheelbase and the leading and trailing axles reduced cornering stability and increased weight. The Bo-Bo con ...
