ATM Class 4600 And 4700
The ATM Class 4600 and 4700 are a series of articulated trams used by the ATM on the Milan urban tramway network. They were projected in the 1950s as an articulated version of the series 5300; originally a series of 15 cars (to be numbered from 4601 to 4615) was foreseen, but the two last units were delivered in an experimental ″all electric″ version and, because of that, were numbered in the 4700 series. Some years later a second series of "all-electric" cars was built, numbered from 4716 to 4733. Originally, the cars were painted in a two-tone-green livery, later repainted in the orange livery, and since 2010 in a white-and-yellow livery.

Trolley Pole
A trolley pole is a tapered cylindrical pole of wood or metal, used to transfer electricity from a "live" (electrified) overhead wire to the control and the electric traction motors of a tram or trolley bus. It is a type of current collector. The use of overhead wire in a system of current collection is reputed to be the 1880 invention of Frank J. Sprague, but the first working trolley pole was developed and demonstrated by Charles Van Depoele, in autumn 1885. Middleton, William D. (1967). ''The Time of the Trolley'', pp. 63–65, 67. Milwaukee: Kalmbach Publishing. . Etymology The term "trolley", also used to describe the pole or the passenger car using the trolley pole, is derived from the grooved conductive wheel attached to the end of the pole that "trolls" the overhead wire. The term "trolley" predates the invention of the trolley pole. The earliest electric cars did not use a pole, but rather a system in which each tramcar dragged behind it an overhead cable connected ...

Breda Costruzioni Ferroviarie
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 ...

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 ...

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 ...

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors ar ... [...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 ...

Articulated Tram
Trams have been used since the 19th century, and since then, there have been various uses and designs for trams around the world. This article covers the many design types, most notably the articulated, double-decker, drop-centre, low-floor, single ended, double-ended, rubber -tired, and tram-train; and the various uses of trams, both historical and current, most notably cargo trams, a dog car, hearse tram, maintenance trams, a mobile library service, a nursery tram, a restaurant tram, a tourist tram, and as mobile offices. Types of Tram Designs Articulated Articulated trams, invented and first used by the Boston Elevated Railway in 1912–13 at a total length of about twelve meters long (40 ft) for each pioneering example of twin-section articulated tram car, have two or more body sections, connected by flexible joints and a round platform at their pivoting midsection(s). Like articulated buses, they have increased passenger capacity. In practice, these trams can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azienda Trasporti Milanesi
The Azienda Trasporti Milanesi (ATM) is the municipal public transport company of Milan and 46 surrounding metropolitan municipalities. It operates 5 metro lines (see Milan Metro), 17 tram lines (see Trams in Milan), 121 bus lines and 4 trolleybus lines (see Trolleybuses in Milan), carrying about 776 million passengers in 2018. ATM manages other minor transport services in Lombardy as well.

Horse-drawn buses were introduced in 1841. Services were run by the ''Società Anonima degli Omnibus'' (SAO), "Omnibus Anonymous Company". The company was responsible for 11 bus lines between 1861 and 1865. Few years later the first h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trams In Milan
The Milan tramway network ( it, Rete tranviaria di Milano) is part of the public transport network of Milan, Italy, operated by Azienda Trasporti Milanesi (ATM). In operation since 1881, the network is currently long, making it one of the biggest in the world. It has the unusual track gauge of ( Italian gauge), and comprises 17 urban lines. While the Milan metro is characterized by a low level of centrality, with no more than two lines ever crossing each other at any of the interchange stations, the tram network is substantially centralized, with nearly half of the lines passing or terminating around Piazza del Duomo, the city central square. History Horses and steam (1876–93) Following the establishment of omnibus services in 1841, Milan acquired its first trams on 8 July 1876, upon the inauguration of the Milan–Monza tramway, which was operated by animal traction. The terminus of this line was at Porta Venezia, outside the city limits. On 24 June 1877, a second tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
