Trams In Tallinn
The Tallinn tram network (''Trammiliiklus Tallinnas'') is the only tram network in Estonia. Together with the four-route trolleybus network ( et), the four tram lines (currently allocated into five routes), with a total length of 19.7 km (12.2 miles) arranged in a roughly cross-shaped layout, provide a backbone for the public transport network in the Estonian capital. All the routes meet up at Hobujaama in the city centre. Trams are unidirectional, one-sided and single-person operated, and much of the network runs on segregated track. The network is operated by Tatra KT4 and KTNF6 types (the latter being former KT4s that have been extended with the addition of a low-floor middle section) and, since 2014, CAF Urbos AXLs. The trams, trolleybuses and motorbuses in Tallinn are operated by the transport operator Tallinna Linnatranspordi AS. This enterprise emerged on 19 July 2012 when ''Tallinna Autobussikoondis'', the motorbus company was merged with ''Tallinna Trammi- ja ...

Tatra KT4
Tatra KT4 is the name of a four-axle type articulated tramcar developed by the Czech firm ČKD Tatra. The first pre-production vehicles entered service in Potsdam in 1975, with the first production vehicles in 1977. A total of 1,747 units were built, with initial deliveries to East Germany (DDR) and later to the USSR and SFR Yugoslavia. KT4 variants were built for both standard gauge and metre gauge tramways. Production of the KT4 tramcar was halted in 1991 due to worldwide economic and political changes at the time. Production was briefly resumed in 1997 to construct the last 20 units for Belgrade, Serbia. Since the start of the 1990s, many of the earliest production tramcars have gone through extensive refurbishment and rebuilding, including the replacement of folding doors and the installation of low-floor center sections. The design of the tram, being without a bogie over the joint necessitates a scissor joint connecting both bogies such that the center of mass does not ...

Horsecar
A horsecar, horse-drawn tram, horse-drawn streetcar (U.S.), or horse-drawn railway (historical), is an animal-powered (usually horse) tram or streetcar. Summary The horse-drawn tram (horsecar) was an early form of public rail transport, which developed out of industrial haulage routes that had long been in existence, and from the omnibus routes that first ran on public streets in the 1820s{{{citation needed, date=February 2022, using the newly improved iron or steel rail or ' tramway'. They were local versions of the stagecoach lines and picked up and dropped off passengers on a regular route, without the need to be pre-hired. Horsecars on tramlines were an improvement over the omnibus, because the low rolling resistance of metal wheels on iron or steel rails (usually grooved from 1852 on) allowed the animals to haul a greater load for a given effort than the omnibus, and gave a smoother ride. The horse-drawn streetcar combined the low cost, flexibility, and safety of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lasnamäe Tram Depot 002
Lasnamäe is the most populous administrative district of Tallinn, the capital of Estonia. The district's population is about 119,000, the majority of which is Russian-speaking. Local housing is mostly represented by 5–16 stories high panel blocks of flats, built in the 1970–1990s. The district lies in the eastern part of Tallinn. In the east it is bordered by the Pirita River; in the north and northwest a limestone escarpment (part of the Baltic Klint) separates Lasnamäe from Pirita and Kesklinn. The district is situated on a flat limestone plateau that lies 30–52 m above sea level. The highest point in Lasnamäe is the Sõjamägi Hill at 54 m asl. Lasnamäe can be divided into two distinct areas: the northern part is residential, while the southern part around Peterburi Road (Tallinn-Narva road, part of E20) and up to the border with Rae Parish is mainly industrial. Lennart Meri Tallinn Airport is also administratively located in Lasnamäe. History The oldest traces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second World War
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), starvat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Gauge Conversion
Gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. Sleepers If tracks are converted to a narrower gauge, the existing sleepers (ties) may be used. However, replacement is required if the conversion is to a wider gauge. Some sleepers may be long enough to accommodate the fittings of both existing and alternative gauges. Wooden sleepers are suitable for conversion because they can be drilled for the repositioned rail spikes. Being difficult to drill, concrete sleepers are less suitable for conversion. Concrete sleepers may be cast with alternative gauge fittings in place, an example being those used during the conversion of the Melbourne–Adelaide railway from to . Steel sleepers may have alternative gauge fittings cast at production, may be drilled for new fittings or may be welded with new fittings. Structures Conversion from a narrow to a wider gauge may require enlargement of the structure gauge of the bridg ... [...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, 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 ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk (Byelorussian SSR), Tashkent ( Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Govern ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was List of wars and anthropogenic disasters by death toll, one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific Ocean, Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in Genocides in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...

Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high- temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine), turbine blades ( gas turbine), a rotor (Wankel engine), or a nozzle ( jet engine). This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine was more important. The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860, and the first modern internal combustion eng ...
