FS Class E.421
The FS Class E.421 locomotive of the Italian State Railways (FS) was a battery electric locomotive, built as a single unit (E.421.1) and used for shunting at the old Milano Centrale railway station. It was the only battery electric locomotive to be registered in the FS fleet. History The E.421 locomotive was built by in 1921, with electrical equipment by Tecnomasio Italiano Brown Boveri (TIBB). The batteries were built by Società Generale Italiana Accumulatori. The batteries were housed in the two bonnets. They weighed 30 tons and supplied electric power at a voltage of 450 V, which operated the four traction motors, one for each axle. The E.421 was used for shunting at the old central station of Milan, particularly in the western area, terminus of the Varese railway, which was electrified with a third rail A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi- ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italian State Railways
Ferrovie dello Stato Italiane S.p.A. ( "Italian Railways of the State"; previously only Ferrovie dello Stato, hence the abbreviation FS) is Italy's national state-owned railway holding company that manages transport, infrastructure, real estate services and other services in Italy and other European countries. History Early years The company was instituted by an act on 22 April 1905, taking control over the majority of the national railways, which up until that time were privately owned and managed. The president was nominated by the government. The first Director General was Riccardo Bianchi. In June 1912 Ferrovie dello Stato owned 5021 steam locomotives, 151 railcars, 10,037 coaches, 3371 baggage cars and 92,990 goods wagons.Victor Freiherr von Röll''Enzyklopädie des Eisenbahnwesens.''Band 6, Urban & Schwarzenberg, Berlin, 1914, p. 297.

Battery Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of re ...

Shunting (rail)
Shunting, in railway operations, is the process of sorting items of rolling stock into complete trains, or the reverse. In the United States this activity is known as switching. Motive power Motive power is normally provided by a locomotive known as a ''shunter'' (in the UK) or switcher (in the US). Most shunter/switchers are now diesel-powered but steam and even electric locomotives have been used. Where locomotives could not be used (e.g. because of weight restrictions) shunting operations have in the past been effected by horses or capstans. Hazards Coupling The terms "shunter" and "switcher" are applied not only to locomotives but to employees engaged on the ground with shunting/switching operations. The task of such personnel is particularly dangerous because not only is there the risk of being run over, but on some railway systems—particularly ones that use buffer-and-chain/screw coupling systems—the shunters have to get between the wagons/carriages in order to ...

Milano Centrale Railway Station
Milano Centrale ( it, Stazione Milano Centrale) is the main railway station of the city of Milan, Italy, and is the largest railway station in Europe by volume. The station is a terminus and located at the northern end of central Milan. It was officially inaugurated in 1931 to replace the old central station (built 1864), which was a transit station but with a limited number of tracks and space, so could not handle the increased traffic caused by the opening of the Simplon Tunnel in 1906. Milano Centrale has high-speed connections to Turin in the west, Venice via Verona in the east and on the north-south mainline to Bologna, Rome, Naples and Salerno. The Simplon and Gotthard railway lines connect Milano Centrale to Bern and Geneva via Domodossola and Zürich via Chiasso in Switzerland. Destinations of inter-city and regional railways radiate from Milano Centrale to Ventimiglia (border of France), Genova, Turin, Domodossola (border of Swiss Canton of Valais/Wallis), Tirano (bord ...

Tecnomasio Italiano Brown Boveri
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] |
Traction Battery
An electric vehicle battery (EVB, also known as a traction battery) is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). Typically lithium-ion batteries, they are specifically designed for high electric charge (or energy) capacity. Electric vehicle batteries differ from starting, lighting, and ignition (SLI) batteries as they are designed to give power over sustained periods of time and are deep-cycle batteries. Batteries for electric vehicles are characterized by their relatively high power-to-weight ratio, specific energy and energy density; smaller, lighter batteries are desirable because they reduce the weight of the vehicle and therefore improve its performance. Compared to liquid fuels, most current battery technologies have much lower specific energy, and this often impacts the maximum all-electric range of the vehicles. The most common battery type in modern electric vehicles are lithium-io ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traction Motor
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, elevators or electric multiple unit. Traction motors are used in electrically powered rail vehicles ( electric multiple units) and other electric vehicles including electric milk floats, elevators, roller coasters, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems (diesel-electric locomotives, electric hybrid vehicles), and battery electric vehicles. Motor types and control Direct-current motors with series field windings are the oldest type of traction motors. These provide a speed-torque characteristic useful for propulsion, providing high torque at lower speeds for acceleration of the vehicle, and declining torque as speed increases. By arranging the field winding with multiple taps, the speed characteristic can be varied, allowing relatively smooth operator control of acceleration. A further measure of contro ...

Varese
Varese ( , , or ; lmo, label= Varesino, Varés ; la, Baretium; archaic german: Väris) is a city and ''comune'' in north-western Lombardy, northern Italy, north-west of Milan. The population of Varese in 2018 has reached 80,559. It is the capital of the Province of Varese. The hinterland or exurban part of the city is called ''Varesotto''. Geography The city of Varese lies at the foot of Sacro Monte di Varese, part of the Campo dei Fiori mountain range, that hosts an astronomical observatory, as well as the Prealpino Geophysical Centre. The village which is in the middle of the mountain is called Santa Maria del Monte because of the medieval sanctuary, which is reached through the avenue of the chapels of the Sacred Mountain. Varese is situated on seven hills: the San Pedrino Hill, the Giubiano Hill, the Campigli Hill, the Sant'Albino Hill, the Biumo Superiore Hill, Colle di Montalbano (Villa Mirabello) and the Hill of Miogni. The city also looks over Lake Varese. Cli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Third Rail
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third rail systems are usually supplied from direct current electricity. Modern tram systems, street-running, avoid the risk of electrocution by the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge railways. Description Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") ...
