At inception it had 175,700 employees, and is the largest rolling stock manufacturer in the world, the parent company of CRRC Corporation is CRRC Group, a state-owned enterprise that was supervised by the State-owned Assets Supervision and Administration Commission of the State Council. China CNR Corporation and CSR Corporation Limited, once one company, were separated in 2000, rationals given for the merger were increased efficiency, and the ability to better compete internationally with combined resources. Total employment of the combine was 175,700 persons, after formation, CRRC began efforts to expand overseas, after being awarded a 284 vehicle order for metro cars for Massachusetts Bay Transportation Authoritys Red and Orange lines with a $556. In mid 2015 production began at a stock plant in Batu Gajah, Perak, Malaysia, a satellite of Zhuzhou Electric Locomotive. In late 2015, Yu Weiping, the CRRC vice-president at the time, stated the company planned to double overseas sales over five years, interim six month financial results for the new company showed an increase in overseas revenue of over 60%. Half year revenue was 91.8 billion Yuan, with a profit of 19.5 billion Yuan. Non rail revenue was 20.94 billion Yuan, in March 2016, CRRC was awarded a contract to build 400 7000-series cars for the Chicago Transit Authority, with an option for another 446 cars. The cost of the contract was $632 million up to $1.31 billion with options, in March 2017, CRRC was awarded a contract by SEPTA to construct 45 bi-level rail cars with the option for 10 additional cars for delivery in October 2019. CRRC was selected over Hyundai Rotem and Bombardier, which bid on the bi-level contract and had each produced equipment for SEPTA in the past. On 8 January 2016 CRRC Corporation purchased 13. 06% stake of China United Insurance Holding from China Insurance Security Fund for RMB4.455 billion, high-speed rail in China Official website

Ankara
–
Ankara, formerly known as Ancyra and Angora, is the capital of the Republic of Turkey. With a population of 4,587,558 in the center and 5,150,072 in its province. Ankara was Atatürks headquarters from 1920 and has been the capital of the Republic since its founding in 1923, the government is a prominent employer, but Ankara is also an important commercial and industrial city, located at the center of Turkeys road and railway networks. The city gave its name to the Angora wool shorn from Angora rabbits, the long-haired Angora goat, the area is also known for its pears, honey, and muscat grapes. Ankara is an old city with various Hittite, Phrygian, Hellenistic, Roman, Byzantine. The historical center of town is a hill rising 150 m over the left bank of the Ankara Çayı, a tributary of the Sakarya River. The hill remains crowned by the ruins of the old citadel, as with many ancient cities, Ankara has gone by several names over the ages. It has been identified with the Hittite cult center Ankuwaš, although remains a matter of debate. In classical antiquity and during the period, the city was known as Ánkyra in Greek and Ancyra in Latin. Following its annexation by the Seljuk Turks in 1073, the city known in many European languages as Angora. The form Angora is preserved in the names of breeds of different kinds of animals. The oldest settlements in and around the city center of Ankara belonged to the Hattic civilization which existed during the Bronze Age and was gradually absorbed c, 2000–1700 BC by the Indo-European Hittites. In Phrygian tradition, King Midas was venerated as the founder of Ancyra, but Pausanias mentions that the city was far older. Persian sovereignty lasted until the Persians defeat at the hands of Alexander the Great who conquered the city in 333 BC, Alexander came from Gordion to Ankara and stayed in the city for a short period. After his death at Babylon in 323 BC and the subsequent division of his empire among his generals, Ankara, by that time the city also took its name Ἄγκυρα which, in slightly modified form, provides the modern name of Ankara. Other centers were Pessinos, todays Balhisar, for the Trocmi tribe, the city was then known as Ancyra. The Celtic element was probably relatively small in numbers, an aristocracy which ruled over Phrygian-speaking peasants. However, the Celtic language continued to be spoken in Galatia for many centuries

Turkey
–
Turkey, officially the Republic of Turkey, is a transcontinental country in Eurasia, mainly in Anatolia in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe. Turkey is a democratic, secular, unitary, parliamentary republic with a cultural heritage. The country is encircled by seas on three sides, the Aegean Sea is to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, Ankara is the capital while Istanbul is the countrys largest city and main cultural and commercial centre. Approximately 70-80% of the countrys citizens identify themselves as ethnic Turks, other ethnic groups include legally recognised and unrecognised minorities. Kurds are the largest ethnic minority group, making up approximately 20% of the population, the area of Turkey has been inhabited since the Paleolithic by various ancient Anatolian civilisations, as well as Assyrians, Greeks, Thracians, Phrygians, Urartians and Armenians. After Alexander the Greats conquest, the area was Hellenized, a process continued under the Roman Empire. The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, the empire reached the peak of its power in the 16th century, especially during the reign of Suleiman the Magnificent. During the war, the Ottoman government committed genocides against its Armenian, Assyrian, following the war, the conglomeration of territories and peoples that formerly comprised the Ottoman Empire was partitioned into several new states. Turkey is a member of the UN, an early member of NATO. Turkeys growing economy and diplomatic initiatives have led to its recognition as a regional power while her location has given it geopolitical, the name of Turkey is based on the ethnonym Türk. The first recorded use of the term Türk or Türük as an autonym is contained in the Old Turkic inscriptions of the Göktürks of Central Asia, the English name Turkey first appeared in the late 14th century and is derived from Medieval Latin Turchia. Similarly, the medieval Khazar Empire, a Turkic state on the shores of the Black. The medieval Arabs referred to the Mamluk Sultanate as al-Dawla al-Turkiyya, the Ottoman Empire was sometimes referred to as Turkey or the Turkish Empire among its European contemporaries. The Anatolian peninsula, comprising most of modern Turkey, is one of the oldest permanently settled regions in the world, various ancient Anatolian populations have lived in Anatolia, from at least the Neolithic period until the Hellenistic period. Many of these peoples spoke the Anatolian languages, a branch of the larger Indo-European language family, in fact, given the antiquity of the Indo-European Hittite and Luwian languages, some scholars have proposed Anatolia as the hypothetical centre from which the Indo-European languages radiated. The European part of Turkey, called Eastern Thrace, has also been inhabited since at least forty years ago. It is the largest and best-preserved Neolithic site found to date, the settlement of Troy started in the Neolithic Age and continued into the Iron Age

Rapid transit
–
Rapid transit, also known as heavy rail, metro, subway, tube, or underground, is a type of high-capacity public transport generally found in urban areas. The stations typically have high platforms, without steps inside the trains and they are typically integrated with other public transport and often operated by the same public transport authorities. However, some transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines. It is unchallenged in its ability to transport large numbers of people quickly over short distances with little use of land, variations of rapid transit include people movers, small-scale light metro, and the commuter rail hybrid S-Bahn. The worlds first rapid-transit system was the partially underground Metropolitan Railway which opened as a railway in 1863. In 1868, New York opened the elevated West Side and Yonkers Patent Railway, china has the largest number of rapid transit systems in the world. The worlds longest single-operator rapid transit system by length is the Shanghai Metro. The worlds largest single rapid transit service provider by both length of revenue track (665 miles and number of stations is the New York City Subway. The busiest rapid transit systems in the world by annual ridership are the Tokyo subway system, the Seoul Metropolitan Subway, the Moscow Metro, the Beijing Subway, Metro is the most common term for underground rapid transit systems used by non-native English speakers. One of these terms may apply to a system, even if a large part of the network runs at ground level. In Scotland, however, the Glasgow Subway underground rapid transit system is known as the Subway, in the US, underground mass transit systems are primarily known as subways, whereas the term metro is a shortened reference to a metropolitan area. In that vein, Chicagos commuter rail system, serving the area, is called Metra. Exceptions in naming rapid transit systems are Washington DCs subway system the Washington Metro, Los Angeles Metro Rail, and the Miami Metrorail, the opening of Londons steam-hauled Metropolitan Railway in 1863 marked the beginning of rapid transit. Initial experiences with steam engines, despite ventilation, were unpleasant, experiments with pneumatic railways failed in their extended adoption by cities. Electric traction was more efficient, faster and cleaner than steam, in 1890 the City & South London Railway was the first electric-traction rapid transit railway, which was also fully underground. Both railways were merged into London Underground. The 1893 Liverpool Overhead Railway was designed to use electric traction from the outset, budapest in Hungary and Glasgow, Chicago and New York all converted or purpose-designed and built electric rail services. Advancements in technology have allowed new automated services, hybrid solutions have also evolved, such as tram-train and premetro, which incorporate some of the features of rapid transit systems

Track gauge
–
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails. All vehicles on a network must have running gear that is compatible with the track gauge, as the dominant parameter determining interoperability, it is still frequently used as a descriptor of a route or network. There is a distinction between the gauge and actual gauge at some locality, due to divergence of track components from the nominal. Railway engineers use a device, like a caliper, to measure the actual gauge, the nominal track gauge is the distance between the inner faces of the rails. In current practice, it is specified at a distance below the rail head as the inner faces of the rail head are not necessarily vertical. In some cases in the earliest days of railways, the company saw itself as an infrastructure provider only. Colloquially the wagons might be referred to as four-foot gauge wagons, say and this nominal value does not equate to the flange spacing, as some freedom is allowed for. An infrastructure manager might specify new or replacement track components at a variation from the nominal gauge for pragmatic reasons. Track is defined in old Imperial units or in universally accepted metric units or SI units, Imperial units were established in United Kingdom by The Weights and Measures Act of 1824. In addition, there are constraints, such as the load-carrying capacity of axles. Narrow gauge railways usually cost less to build because they are lighter in construction, using smaller cars and locomotives, as well as smaller bridges, smaller tunnels. Narrow gauge is often used in mountainous terrain, where the savings in civil engineering work can be substantial. Broader gauge railways are generally expensive to build and require wider curves. There is no single perfect gauge, because different environments and economic considerations come into play, a narrow gauge is superior if ones main considerations are economy and tight curvature. For direct, unimpeded routes with high traffic, a broad gauge may be preferable, the Standard, Russian, and 46 gauges are designed to strike a reasonable balance between these factors. In addition to the general trade-off, another important factor is standardization, once a standard has been chosen, and equipment, infrastructure, and training calibrated to that standard, conversion becomes difficult and expensive. This also makes it easier to adopt an existing standard than to invent a new one and this is true of many technologies, including railroad gauges. The reduced cost, greater efficiency, and greater economic opportunity offered by the use of a common standard explains why a number of gauges predominate worldwide

Standard gauge
–
The standard gauge is a widely used railway track gauge. Approximately 55% of the lines in the world are this gauge, all high-speed rail lines, except those in Russia, Uzbekistan, and Finland, are standard gauge. The distance between the edges of the rails is defined to be 1435 mm except in the United States. It is also called the UIC gauge or UIC track gauge, as railways developed and expanded, one of the key issues was the track gauge to be used. The result was the adoption throughout a large part of the world of a gauge of 1435 mm. In North East England, some lines in colliery areas were 4 ft 8 in. All these lines had been widened to standard gauge by 1846, parts of the United States, mainly in the Northeast, adopted the same gauge, because some early trains were purchased from Britain. However, until well into the half of the 19th century, Britain. The American gauges converged as the advantages of equipment interchange became increasingly apparent, notably, all the 5 ft broad gauge track in the South was converted to standard gauge over the course of two days beginning on 31 May 1886. See Track gauge in the United States, snopes categorized this legend as false, but commented that. It is perhaps more fairly labelled as True, but for trivial, the historical tendency to place the wheels of horse-drawn vehicles approximately 5 feet apart probably derives from the width needed to fit a carthorse in between the shafts. Others were 4 ft 4 in or 4 ft 7 1⁄2 in, the English railway pioneer George Stephenson spent much of his early engineering career working for the coal mines of County Durham. He favoured 4 ft 8 in for wagonways in Northumberland and Durham, the Hetton and Springwell wagonways also used this gauge. Stephensons Stockton and Darlington railway was primarily to transport coal from mines near Shildon to the port at Stockton-on-Tees. The initial gauge of 4 ft 8 in was set to accommodate the existing gauge of hundreds of horse-drawn chaldron wagons that were already in use on the wagonways in the mines. The railway used this gauge for 15 years before a change was made to 4 ft 8 1⁄2 in gauge, George Stephenson used the 4 ft 8 1⁄2 in gauge for the Liverpool and Manchester Railway, authorised in 1826 and opened 30 September 1830. The success of this led to Stephenson and his son Robert being employed to engineer several other larger railway projects. Monkland and Kirkintilloch Railway, authorised 1824 and opened 1825, used 4 ft 6 in, Dundee and Newtyle Railway, authorised 1829 and opened 1831, used 4 ft 6 1⁄2 in

Railway electrification system
–
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electrification has many advantages but requires significant capital expenditure, selection of an electrification system is based on economics of energy supply, maintenance, and capital cost compared to the revenue obtained for freight and passenger traffic. Different systems are used for urban and intercity areas, some electric locomotives can switch to different supply voltages to allow flexibility in operation, Electric railways use electric locomotives to haul passengers or freight in separate cars or electric multiple units, passenger cars with their own motors. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network, some electric railways have their own dedicated generating stations and transmission lines but most purchase power from an electric utility. The railway usually provides its own lines, switches and transformers. Power is supplied to moving trains with a continuous conductor running along the track usually takes one of two forms. The first is a line or catenary wire suspended from poles or towers along the track or from structure or tunnel ceilings. Locomotives or multiple units pick up power from the wire with pantographs on their roofs that press a conductive strip against it with a spring or air pressure. Examples are described later in this article, the second is a third rail mounted at track level and contacted by a sliding pickup shoe. Both overhead wire and third-rail systems usually use the rails as the return conductor. In comparison to the alternative, the diesel engine, electric railways offer substantially better energy efficiency, lower emissions. Electric locomotives are usually quieter, more powerful, and more responsive and they have no local emissions, an important advantage in tunnels and urban areas. Different regions may use different supply voltages and frequencies, complicating through service, the limited clearances available under catenaries may preclude efficient double-stack container service. Possible lethal electric current due to risk of contact with high-voltage contact wires, overhead wires are safer than third rails, but they are often considered unsightly. These are independent of the system used, so that. The permissible range of voltages allowed for the voltages is as stated in standards BS EN50163. These take into account the number of trains drawing current and their distance from the substation, railways must operate at variable speeds. Until the mid 1980s this was only practical with the brush-type DC motor, since such conversion was not well developed in the late 19th century and early 20th century, most early electrified railways used DC and many still do, particularly rapid transit and trams
8.
Third rail
–
A third 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 transit or rapid transit system. Third rail systems are supplied from direct current electricity. The third-rail system of electrification is unrelated to the third used in dual gauge railways. Third-rail systems are a means of providing electric power to trains. On most systems, the rail is placed on the sleeper ends outside the running rails. The conductor rail is supported on ceramic insulators or insulated brackets, the trains have metal contact blocks called shoes which make contact with the conductor rail. The traction current is returned to the station through the running rails. The conductor rail is made of high conductivity steel. The conductor rails have to be interrupted at level crossings, crossovers, tapered rails are provided at the ends of each section, to allow a smooth engagement of the trains contact shoes. Because third rail systems present electric shock hazards close to the ground, a very high current must therefore be used to transfer adequate power, resulting in high resistive losses, and requiring relatively closely spaced feed points. The electrified rail threatens electrocution of anyone wandering or falling onto the tracks. This can be avoided by using platform screen doors, or the risk can be reduced by placing the rail on the side of the track away from the platform. There is also a risk of pedestrians walking onto the tracks at level crossings, the Paris Metro has graphic warning signs pointing out the danger of electrocution from urinating on third rails, precautions which Chicago did not have. The end ramps of conductor rails present a practical limitation on speed due to the impact of the shoe. The world speed record for a rail train is 174 km/h attained on 11 April 1988 by a British Class 442 EMU. In the event of a collision with an object, the beveled end ramps of bottom running systems can facilitate the hazard of having third rail penetrate the interior of a passenger car. This is believed to have contributed to the death of five passengers in the Valhalla train crash of 2015, third rail systems using top contact are prone to accumulations of snow, or ice formed from refrozen snow, and this can interrupt operations

Turkish language
–
Outside of Turkey, significant smaller groups of speakers exist in Germany, Bulgaria, Macedonia, Northern Cyprus, Greece, the Caucasus, and other parts of Europe and Central Asia. Cyprus has requested that the European Union add Turkish as an official EU language, in 1928, as one of Atatürks Reforms in the early years of the Republic of Turkey, the Ottoman Turkish alphabet was replaced with a Latin alphabet. The distinctive characteristics of Turkish are vowel harmony and extensive agglutination, the basic word order of Turkish is subject–object–verb. Turkish has no classes or grammatical gender. Turkish has a strong T–V distinction and usage of honorifics, Turkish uses second-person pronouns that distinguish varying levels of politeness, social distance, age, courtesy or familiarity toward the addressee. The plural second-person pronoun and verb forms are used referring to a person out of respect. Turkic languages belong to the Altaic language group, the Turkic family comprises some 30 living languages spoken across Eastern Europe, Central Asia, and Siberia. Turkish is a member of the Oghuz group of languages, a subgroup of the Turkic language family, there is a high degree of mutual intelligibility between Turkish and the other Oghuz Turkic languages, including Azerbaijani, Turkmen, Qashqai, Gagauz, and Balkan Gagauz Turkish. The earliest known Old Turkic inscriptions are the three monumental Orkhon inscriptions found in modern Mongolia, erected in honour of the prince Kul Tigin and his brother Emperor Bilge Khagan, these date back to the second Turk Kaghanate. The Seljuqs of the Oghuz Turks, in particular, brought their language, following the adoption of Islam c. Turkish literature during the Ottoman period, particularly Divan poetry, was influenced by Persian, including the adoption of poetic meters. One of the tasks of the newly established association was to initiate a reform to replace loanwords of Arabic. By banning the usage of imported words in the press, the association succeeded in removing several hundred words from the language. While most of the words introduced to the language by the TDK were newly derived from Turkic roots, owing to this sudden change in the language, older and younger people in Turkey started to differ in their vocabularies. While the generations born before the 1940s tend to use the terms of Arabic or Persian origin. The past few decades have seen the work of the TDK to coin new Turkish words to express new concepts and technologies as they enter the language. Many of these new words, particularly information technology terms, have received widespread acceptance, however, the TDK is occasionally criticized for coining words which sound contrived and artificial. Some earlier changes—such as bölem to replace fırka, political party—also failed to meet with popular approval, some words restored from Old Turkic have taken on specialized meanings, for example betik is now used to mean script in computer science

Light rail
–
Light rail, light rail transit or fast tram is urban public transport using rolling stock similar to a tramway, but operating at a higher capacity, and often on an exclusive right-of-way. A few light rail networks tend to have closer to rapid transit or even commuter rail. Other light rail networks are tram-like in nature and partially operate on streets, Light rail systems are found throughout the world, on all inhabited continents. They have been popular in recent years due to their lower capital costs. The term light rail was coined in 1972 by the U. S, Urban Mass Transportation Administration to describe new streetcar transformations that were taking place in Europe and the United States. In Germany the term Stadtbahn was used to describe the concept, and many in UMTA wanted to adopt the direct translation, however, UMTA finally adopted the term light rail instead. Light in this context is used in the sense of intended for light loads and fast movement, the infrastructure investment is also usually lighter than would be found for a heavy rail system. The Transportation Research Board defined light rail in 1977 as a mode of urban transportation utilizing predominantly reserved, electrically propelled rail vehicles operate singly or in trains. LRT provides a range of passenger capabilities and performance characteristics at moderate costs. Light rail is a generic international English phrase for these types of rail systems, the use of the generic term light rail avoids some serious incompatibilities between British and American English. The word trolley is used as a synonym for streetcar in the United States. A further difference arose because, while Britain abandoned all of its trams except Blackpool after World War II, when these cities upgraded to new technology, they called it light rail to differentiate it from their existing streetcars since some continued to operate both the old and new systems. Conventional rail technologies including high-speed, freight, commuter/regional, and metro/subway/elevated urban transit systems are considered heavy rail, people movers and personal rapid transit are even lighter, at least in terms of capacity. Monorail is a technology that has been more successful in specialized services than in a commuter transit role. Due to varying definitions, it is hard to distinguish between what is called light rail, and other forms of urban and commuter rail, a system described as light rail in one city may be considered to be a streetcar or tram system in another. Conversely, some lines that are called light rail are in very similar to rapid transit, in recent years. Some light rail systems, such as Sprinter, bear little similarity to urban rail, in the United States, light rail has become a catch-all term to describe a wide variety of passenger rail systems. There is a significant difference in cost between these different classes of light rail transit, tram-like systems are often less expensive than metro-like systems by a factor of two or more
