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. 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 generated in large and efficient generating stations, transmitted to the railway network and distributed to the trains; some electric railways have their own dedicated generating stations and transmission lines but most purchase power from an electric utility. The railway provides its own distribution lines and transformers. Power is supplied to moving trains with a continuous conductor running along the track that takes one of two forms: overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings. Both overhead wire and third-rail systems use the running rails as the return conductor but some systems use a separate fourth rail for this purpose. In comparison to the principal alternative, the diesel engine, electric railways offer better energy efficiency, lower emissions and lower operating costs.
Electric locomotives are usually quieter, more powerful, more responsive and reliable than diesels. They have an important advantage in tunnels and urban areas; some electric traction systems provide regenerative braking that turns the train's kinetic energy back into electricity and returns it to the supply system to be used by other trains or the general utility grid. While diesel locomotives burn petroleum, electricity can be generated from diverse sources including renewable energy. Disadvantages of electric traction include high capital costs that may be uneconomic on trafficked routes. Different regions may use different supply voltages and frequencies, complicating through service and requiring greater complexity of locomotive power; the limited clearances available under overhead lines may preclude efficient double-stack container service. Railway electrification has increased in the past decades, as of 2012, electrified tracks account for nearly one third of total tracks globally. Electrification systems are classified by three main parameters: Voltage Current Direct current Alternating current Frequency Contact system Third rail Fourth rail Overhead lines Overhead lines plus linear motor Four rail system Five rail systemSelection of an electrification system is based on economics of energy supply and capital cost compared to the revenue obtained for freight and passenger traffic.
Different systems are used for intercity areas. Six of the most used voltages have been selected for European and international standardisation; some of these are independent of the contact system used, so that, for example, 750 V DC may be used with either third rail or overhead lines. There are many other voltage systems used for railway electrification systems around the world, the list of railway electrification systems covers both standard voltage and non-standard voltage systems; the permissible range of voltages allowed for the standardised voltages is as stated in standards BS EN 50163 and IEC 60850. These take into account the number of trains drawing their distance from the substation. Increasing availability of high-voltage semiconductors may allow the use of higher and more efficient DC voltages that heretofore have only been practical with AC. 1,500 V DC is used in Japan, Hong Kong, Republic of Ireland, France, New Zealand, the United States. In Slovakia, there are two narrow-gauge lines in the High Tatras.
In the Netherlands it is used on the main system, alongside 25 kV on the HSL-Zuid and Betuwelijn, 3000 V south of Maastricht. In Portugal, it is used in Denmark on the suburban S-train system. In the United Kingdom, 1,500 V DC was used in 1954 for the Woodhead trans-Pennine route; the system was used for suburban electrification in East London and Manchester, now converted to 25 kV AC. It is now only used for the Wear Metro. In India, 1,500 V DC was the first electrification system launched in 1925 in Mumbai area. Between 2012-2016, the electrification was converted to 25 kV 50 Hz AC, the countrywide system. 3 kV DC is used in Belgium, Spain, the northern Czech Republic, Slovenia, South Africa, former Soviet Union countries and the Netherlands. It was used by the Milwaukee Road from Harlowton, Montana to Seattle-Tacoma, across the Continental Divide and including extensive branch and loop lines in Montana, by the Delaware, Lackawanna & Western Railroad in the United States, the Kolkata suburban railway in India, before it was converted to 25 kV 50 Hz AC.

Line 10 (CPTM)
Line 10 is a line of the Companhia Paulista de Trens Metropolitanos commuter rail system in São Paulo, Brazil. The number of passengers on it increased because the integration to the Tamanduateí's station; the single model of train running at this line is the 2100 Series. Imported from Spain, this model was projected to take long journeys; because of the cars' length, the model runs only in this line, which has long distances between the stations. Has only four doors per car; each train is composed by six cars with air conditioned. Santos-Jundiaí Railroad Line 9 Official page of the CPTM Secretaria dos Transportes Metropolitanos
São Paulo is a municipality in the Southeast Region of Brazil. The metropolis is an alpha global city and the most populous city in Brazil, the Western Hemisphere and the Southern Hemisphere, besides being the largest Portuguese-speaking city in the world; the municipality is the Earth's 11th largest city proper by population. The city is the capital of the surrounding state of São Paulo, the most populous and wealthiest state in Brazil, it exerts strong international influences in commerce, finance and entertainment. The name of the city honors Saint Paul of Tarsus; the city's metropolitan area, the Greater São Paulo, ranks as the most populous in Brazil and the 12th most populous on Earth. The process of conurbation between the metropolitan areas located around the Greater São Paulo created the São Paulo Macrometropolis, a megalopolis with more than 30 million inhabitants, one of the most populous urban agglomerations in the world. Having the largest economy by GDP in Latin America and the Southern Hemisphere, the city is home to the São Paulo Stock Exchange.
Paulista Avenue is the economic core of São Paulo. The city has the 11th largest GDP in the world, representing alone 10.7% of all Brazilian GDP and 36% of the production of goods and services in the state of São Paulo, being home to 63% of established multinationals in Brazil, has been responsible for 28% of the national scientific production in 2005. With a GDP of US$477 billion, the São Paulo city alone would have ranked 26th globally compared with countries by 2017 estimates; the metropolis is home to several of the tallest skyscrapers in Brazil, including the Mirante do Vale, Edifício Itália, North Tower and many others. The city has cultural and political influence both nationally and internationally, it is home to monuments and museums such as the Latin American Memorial, the Ibirapuera Park, Museum of Ipiranga, São Paulo Museum of Art, the Museum of the Portuguese Language. The city holds events like the São Paulo Jazz Festival, São Paulo Art Biennial, the Brazilian Grand Prix, São Paulo Fashion Week, the ATP Brasil Open, the Brasil Game Show and the Comic Con Experience.
The São Paulo Gay Pride Parade rivals the New York City Pride March as the largest gay pride parade in the world. São Paulo is a cosmopolitan, melting pot city, home to the largest Arab and Japanese diasporas, with examples including ethnic neighborhoods of Mercado and Liberdade respectively. São Paulo is home to the largest Jewish population in Brazil, with about 75,000 Jews. In 2016, inhabitants of the city were native to over 200 different countries. People from the city are known as paulistanos, while paulistas designates anyone from the state, including the paulistanos; the city's Latin motto, which it has shared with the battleship and the aircraft carrier named after it, is Non ducor, which translates as "I am not led, I lead." The city, colloquially known as Sampa or Terra da Garoa, is known for its unreliable weather, the size of its helicopter fleet, its architecture, severe traffic congestion and skyscrapers. São Paulo was one of the host cities of the 2014 FIFA World Cup. Additionally, the city hosted the IV Pan American Games and the São Paulo Indy 300.
The region of modern-day São Paulo known as Piratininga plains around the Tietê River, was inhabited by the Tupi people, such as the Tupiniquim and Guarani. Other tribes lived in areas that today form the metropolitan region; the region was divided in Caciquedoms at the time of encounter with the Europeans. The most notable Cacique was Tibiriça, known for his support for the Portuguese and other European colonists. Among the many indigenous names that survive today are Tietê, Tamanduateí, Anhangabaú, Diadema, Itapevi, Embu-Guaçu etc... The Portuguese village of São Paulo dos Campos de Piratininga was marked by the founding of the Colégio de São Paulo de Piratininga on January 25, 1554; the Jesuit college of twelve priests included Spanish priest José de Anchieta. They built a mission on top of a steep hill between the Tamanduateí rivers, they first had a small structure built of rammed earth, made by American Indian workers in their traditional style. The priests wanted to evangelize – teach the Indians who lived in the Plateau region of Piratininga and convert them to Christianity.
The site was separated from the coast by the Serra do Mar, called by the Indians Serra Paranapiacaba. The college was named for a Christian saint and its founding on the feast day of the celebration of the conversion of the Apostle Paul of Tarsus. Father José de Anchieta wrote this account in a letter to the Society of Jesus: The settlement of the region's Courtyard of the College began in 1560. During the visit of Mem de Sá, Governor-General of Brazil, the Captaincy of São Vicente, he ordered the transfer of the population of the Village of Santo André da Borda do Campo to the vicinity of the college, it was named "College of St. Paul Piratininga"; the new location was on a steep hill adjacent to a large wetland, the lowland do Carmo. It offered better protection from attacks by local Indian groups, it was renamed belonging to the Captaincy of São Vicente. For the next two centuries, São Paulo developed as a poor and isolated village that survived through the cultivation of subsistence crops by the labor of natives.
For a long time, São Paulo was the only village in Brazil's interior, as travel was too difficult for many to reach the area. Mem de Sá forbade colonists to use the "Path Pir
Brazil the Federative Republic of Brazil, is the largest country in both South America and Latin America. At 8.5 million square kilometers and with over 208 million people, Brazil is the world's fifth-largest country by area and the fifth most populous. Its capital is Brasília, its most populated city is São Paulo; the federation is composed of the union of the 26 states, the Federal District, the 5,570 municipalities. It is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 kilometers, it borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, extensive natural resources spanning numerous protected habitats; this unique environmental heritage makes Brazil one of 17 megadiverse countries, is the subject of significant global interest and debate regarding deforestation and environmental protection.
Brazil was inhabited by numerous tribal nations prior to the landing in 1500 of explorer Pedro Álvares Cabral, who claimed the area for the Portuguese Empire. Brazil remained a Portuguese colony until 1808, when the capital of the empire was transferred from Lisbon to Rio de Janeiro. In 1815, the colony was elevated to the rank of kingdom upon the formation of the United Kingdom of Portugal and the Algarves. Independence was achieved in 1822 with the creation of the Empire of Brazil, a unitary state governed under a constitutional monarchy and a parliamentary system; the ratification of the first constitution in 1824 led to the formation of a bicameral legislature, now called the National Congress. The country became a presidential republic in 1889 following a military coup d'état. An authoritarian military junta came to power in 1964 and ruled until 1985, after which civilian governance resumed. Brazil's current constitution, formulated in 1988, defines it as a democratic federal republic. Due to its rich culture and history, the country ranks thirteenth in the world by number of UNESCO World Heritage Sites.
Brazil is considered an advanced emerging economy. It has the ninth largest GDP in the world by nominal, eight and PPP measures, it is one of the world's major breadbaskets, being the largest producer of coffee for the last 150 years. It is classified as an upper-middle income economy by the World Bank and a newly industrialized country, with the largest share of global wealth in Latin America. Brazil is a regional power and sometimes considered a great or a middle power in international affairs. On account of its international recognition and influence, the country is subsequently classified as an emerging power and a potential superpower by several analysts. Brazil is a founding member of the United Nations, the G20, BRICS, Union of South American Nations, Organization of American States, Organization of Ibero-American States and the Community of Portuguese Language Countries, it is that the word "Brazil" comes from the Portuguese word for brazilwood, a tree that once grew plentifully along the Brazilian coast.
In Portuguese, brazilwood is called pau-brasil, with the word brasil given the etymology "red like an ember", formed from brasa and the suffix -il. As brazilwood produces a deep red dye, it was valued by the European textile industry and was the earliest commercially exploited product from Brazil. Throughout the 16th century, massive amounts of brazilwood were harvested by indigenous peoples along the Brazilian coast, who sold the timber to European traders in return for assorted European consumer goods; the official Portuguese name of the land, in original Portuguese records, was the "Land of the Holy Cross", but European sailors and merchants called it the "Land of Brazil" because of the brazilwood trade. The popular appellation eclipsed and supplanted the official Portuguese name; some early sailors called it the "Land of Parrots". In the Guarani language, an official language of Paraguay, Brazil is called "Pindorama"; this was the name the indigenous population gave to the region, meaning "land of the palm trees".
Some of the earliest human remains found in the Americas, Luzia Woman, were found in the area of Pedro Leopoldo, Minas Gerais and provide evidence of human habitation going back at least 11,000 years. The earliest pottery found in the Western Hemisphere was excavated in the Amazon basin of Brazil and radiocarbon dated to 8,000 years ago; the pottery was found near Santarém and provides evidence that the tropical forest region supported a complex prehistoric culture. The Marajoara culture flourished on Marajó in the Amazon delta from 800 CE to 1400 CE, developing sophisticated pottery, social stratification, large populations, mound building, complex social formations such as chiefdoms. Around the time of the Portuguese arrival, the territory of current day Brazil had an estimated indigenous population of 7 million people semi-nomadic who subsisted on hunting, fishing and migrant agriculture; the indigenous population of Brazil comprised several large indigenous ethnic groups. The Tupí people were subdivided into the Tupiniquins and Tupinambás, there were many subdivisions of the other gro
Line 3 (São Paulo Metro)
Line 3 of the São Paulo Metro covers the stretch of the metro network between Palmeiras-Barra Funda and Corinthians-Itaquera. It was called the East-West Line. Line 3 is the busiest in the system; this line called the East-West line, was only planned to be 7 kilometres long, connecting the Casa Verde and Vila Maria districts of São Paulo, passing through the center of Barra Funda, Sé, Tatuapé, be underground. But after a lengthy debate, it was decided that it would be constructed on the surface, taking advantage of the old Rede Ferroviária Federal train bed and sharing 23 kilometres of its lines—a move that prevented many expropriations. Construction began in 1972. With this design change, the East-West line would be more than 30 kilometres long between Praça da Sé and Guaianases, parallel to the railroad tracks; the stretch between Guaianases and Calmon Viana, in Poá was planned to be built in a second phase, making full use the rail bed. The strength of this design change would be a cost equivalent to one third of the original budget.
Because of international trends that dictate that the rail for metro systems used for urban transport be made exclusive to the metro, the design was changed again. It was up to the Rede Ferroviária Federal to modernize this passage. For this reason, the line opened overloaded. Once this impasse was resolved, construction began on the western section. On March 10, 1979 the first stretch, between Sé and Brás stations was opened. In the west, the line ended in Barra Funda; the current configuration is the same since 1988. The current record demand was made on November 2008, with the transport of 1,468,935 people. On May 2–3, 2009 the stretch between Anhangabaú and Santa Cecília stations was closed to allow for the use of a tunnel boring machine being used for the extension project of Line 4. In 2010 work began on the installation of glass doors on the Line 3 platforms, starting with the Vila Matilde, Carrão and Penha stations. An expansion is planned from Palmeiras-Barra Funda to Pio XI. Another extension is planned from Corinthians-Itaquera to Jacu Pêssego
