FS Class E.428
The FS E.428 was a class of Italian railways electric locomotives. They were introduced in the course of the 1930s, for fast services on the Florence–Rome railway, being decommissioned in the 1980s. History When in the 1930s, in the course of the Fascist government's program of railways development, a new locomotive was needed to provide a fast service on the newly electrified Milan-Rome mainline at 3,000 V DC. This was also permitted by the introduction of new metallic passenger cars, capable of relative higher speeds. The requirement was shipped to the FS design team of Ing. Giuseppe Bianchi at Florence. The new locomotive was impressive for the times: huge, heavy, powerful and fast. They were longer than the E.626, the first Italian DC electric locomotives, and weighed more. The original requirement asked for the notable service speed of , but this was later reduced to . The E.428 was to be built in conjunction with a lighter version, the E.326, but those proved unsuc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, second, s, and ampere, 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 = \tex ...

Giuseppe Bianchi (engineer)
Giuseppe Bianchi (26 August 1888 – Milan, 20 July 1969) was an Italian railway engineer on the Ferrovie dello Stato between 1913 and 1946. Life Born at Imola, Bianchi graduated in electrical mechanical engineering at the University of Turin in 1912. Offered a job by Ferrovie dello Stato, the operator of the Italian rail network, he was first assigned to the select committee for the electrification of Rome. In 1920 Bianchi was transferred to the office for locomotive research within the Servizio materiale e trazione (Rolling Stock and Locomotive Service) at Florence (where it still resides, under a different name). Although Bianchi distinguished himself through projects involving steam locomotives for mainline services (like the three variations of the planned Class 695 for Ferrovie dello Stato, as well as the Class 691 obtained by rebuilding the Class 690), his work was central to the transition from steam to electric power. As the limitations of using three phase alternati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reggiane Locomotives
Officine Meccaniche Reggiane SpA (commonly referred to as ''Reggiane'') was an Italian industrial manufacturer and aviation company. Reggiane was founded during 1904 by its parent company Caproni, which was in turn owned by the aeronautical engineer Giovanni Battista Caproni. Throughout the company's existence, it was involved in numerous industrial activities, such as railways, agriculture, aeronautics, and processing machinery. During the first half of the Twentieth Century, Reggiane became well known for the design and production of aircraft. Through the development of the Re.2000, an all-metal monoplane, Reggiane gained a reputation for producing relatively agile single-seat fighter aircraft. Following the outbreak of the Second World War, the majority of Reggiane's fighter production was taken over by the '' Regia Aeronautica'' (the Italian Air Force). However, the company continued to manufacture and deliver fighters for various other neutral and Axis-aligned nations ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breda Locomotives
Breda () is a city and municipality in the southern part of the Netherlands, located in the province of North Brabant. The name derived from ''brede Aa'' ('wide Aa' or 'broad Aa') and refers to the confluence of the rivers Mark and Aa. Breda has 185,072 inhabitants on 13 September 2022 and is part of the Brabantse Stedenrij; it is the ninth largest city/municipality in the country, and the third largest in North Brabant after Eindhoven and Tilburg. It is equidistant between Rotterdam and Antwerp. As a fortified city, it was of strategic military and political significance. Although a direct Fiefdom of the Holy Roman Emperor, the city obtained a municipal charter; the acquisition of Breda, through marriage, by the House of Nassau ensured that Breda would be at the centre of political and social life in the Low Countries. Breda had a population of in ; the metropolitan area had a population of . History In the 11th century, Breda was a direct fief of the Holy Roman Emperor, it ...

Railway Locomotives Introduced In 1934
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 faciliti ...

3000 V DC Locomotives
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Lictor
A lictor (possibly from la, ligare, "to bind") was a Roman civil servant who was an attendant and bodyguard to a magistrate who held ''imperium''. Lictors are documented since the Roman Kingdom, and may have originated with the Etruscans. Origin The lictors were instituted by Rome's first king, Romulus, who appointed twelve lictors to attend him. Livy refers to two competing traditions for the reason that Romulus chose that number of lictors. The first version is that twelve was the number of birds that appeared in the augury, which had portended the kingdom to Romulus. The second version, favoured by Livy, is that the number of lictors was borrowed from the Etruscan kings, who had one lictor appointed from each of their twelve states. Eligibility Originally, lictors were chosen from the plebeians, but through most of Roman history, they seemed to have been freedmen. Centurions from the legions were also automatically eligible to become lictors on retirement from the army. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ma ... [...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.
