FS Class E.632
The FS E.632 and E.633 are two classes of Italian railways electric locomotives. They were introduced in the course of the 1980s. The locomotives are nicknamed ''Tigre'' ("tiger"). History The E.632/E.633 were the first Italian locomotives to be provided with electronic traction control system, on the basis of the experiments made with the E.444.005 test locomotive. They were designed to fulfill a requirement from the Ferrovie dello Stato (or FS, then the quasi-monopolist of Italian railways) for a new locomotive to be used with medium-weight passenger trains and a similar one for cargo services on steep lines. The first unit ran on October 11, 1979. After a troublesome program of tests with the first five prototypes, a first order for 90 engines (75 E.633, the cargo version, and 15 E.632) was issued. Regular services began in 1983 in northern Italy. Once the teething problems were solved, the class proved highly successful and reliable. Technical details Differently from ma ...

Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. 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 ( m, kg, s, and A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \text\Omega = \fra ...

Alternate Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio ...

TIBB Locomotives
Tecnomasio was an Italian scientific and precision instrument company founded in the 1860s. By the beginning of the 20th century the company has begun to produce electrical equipment. After financial problems in the early 1900s the company was acquired by Brown Boveri becoming ''Tecnomasio Italiano Brown Boveri'' commonly known as TIBB; instrument production halted and the company became an industrial electrical equipment producer, one of the major companies in Italy. The company became part of the ABB group as ABB Tecnomasio in 1988 after the merger of its parent. The plant in Vado Ligure became part of Adtranz and later part of Bombardier's transportation group. History The origins of Tecnomasio go back as far as 1863 when mechanical and civil engineer Luigi Longoni, instrument maker Carlo Dell'Acqua, and optical scientist Ignazio Porro founded a company in Milan. Porro left the company in 1864 to be replaced by photographer Alessandro Duroni forming the company Duroni, Longon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Locomotives Introduced In 1983
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] |
