Metrovagonmash Ečs
Ečs (81-709) is a type of Soviet metro rolling stock for Prague Metro that derives from the Metrowagonmash E series. History 85 cars were built by Metrowagonmash in Mytishchi near Moscow between 1972 and 1976. The first six cars were delivered in 1973 for test runs, further 44 until 1974, when the trains entered service, firstly as three car sets. 20 cars followed in 1975 which had no tachographs, train radio, or ARS safety system and were used to extend the existing sets to the length of four cars. The last 15 cars were delivered in 1976. In 1992, car 1031 was sold to Siemens to be used as an experimental vehicle for 1500 V DC voltage, 560 kW power output and current collection via overhead wires. In 1994, car 1020 was withdrawn and planned to be rebuilt by ČKD in cooperation with Škoda Škoda means ''pity'' in the Czech and Slovak languages.

81-717/714
81-717/714 is a metro car designed in the Soviet Union in the mid-1970s. The cars were made from 1976 to 2010 by Metrovagonmash and the I. E. Yegorov Vagonmash factories of Mytishchi and Saint Petersburg, respectively. Production is still ongoing for specific models and/or modernizations. The name 81-717 and 81-714 come from the Soviet electric rail vehicle numbering system, where the 81-717 cars are the control cars and the 81-714 are the trailer cars. Unlike the previous metro sets made in the Soviet Union, they never received a lettered classification, thus, they have been known as the 81-series or the "Number Trains" (Номерной Поезд). The "number trains", as they are known colloquially among railfans and some commuters, feature restyled front ends, stronger electric traction motors, complex and wider usage of various electronic devices, and are more advanced than their predecessors, the E-series, with the biggest difference being lack of control desks at every end ...

Škoda Works
The Škoda Works ( cs, Škodovy závody, ) was one of the largest European industrial conglomerates of the 20th century, founded by Czech engineer Emil Škoda in 1859 in Plzeň, then in the Kingdom of Bohemia, Austrian Empire. It is the predecessor of today's Škoda Auto, Doosan Škoda Power and Škoda Transportation companies. History 1859–1899: establishment of Škoda The noble Waldstein family founded the company in 1859 in Plzeň, and Emil Škoda bought it in 1869. It soon established itself as Austria-Hungary's leading arms manufacturer producing heavy guns for the navy, mountain guns or mortars along with the Škoda M1909 machine gun as one of its noted products.

ČKD
ČKD (Českomoravská Kolben-Daněk) () was one of the largest engineering companies in the former Czechoslovakia and today's Czech Republic. It is famous for the Tatra T3, a tramcar that sold 13,991 units worldwide. History ČKD was formed in 1927 from the merger of two smaller companies, Českomoravská-Kolben (founded 1896, produced machinery for hydro dams) and Breitfeld-Daněk (founded 1854, produced machinery for mines and food industry). From 1927 until 1929 ČKD's products included a motorcycle designed by Jaroslav František Koch. It was an advanced four-stroke single-cylinder unit construction double overhead camshaft design of 500cc. It was sold under the marque BD, thus perpetuating the Breitfeld-Daněk identity. In 1929 ČKD sold its motorcycle business to Praga Hostivař, which re-branded the motorcycles under the Praga marque. It was one of the main suppliers to the Czechoslovak state of military vehicles during the 1930s. During the German occupation of Cz ...

Overhead Wires
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 are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Train Radio
In rail transport, a train (from Old French , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and transport people or freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units. Passengers and cargo are carried in railroad cars, also known as wagons. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomotive in the United Kingdom in 1804, trains rapidly spread around the world, allowing freight and passengers to move over land faster and cheaper than ever possible before. Rapid transit and trams were first built in the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tachograph
A tachograph is a device fitted to a vehicle that automatically records its speed and distance, together with the driver's activity selected from a choice of modes. The drive mode is activated automatically when the vehicle is in motion, and modern tachograph heads usually default to the other work mode upon coming to rest. The rest and availability modes can be manually selected by the driver whilst stationary. A tachograph system comprises a sender unit mounted to the vehicle gearbox, the tachograph head and a recording medium. Tachograph heads are of either analogue or digital types. All relevant vehicles manufactured in the EU since 1 May 2006 must be fitted with digital tachograph heads. The recording medium for analogue heads are wax coated paper discs, and for digital heads there are two recording mediums: internal memory (which can be read out with one of a variety of download devices into a so-called .ddd file) and digital driver cards containing a microchip with f ...

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") fo ...
