Estrada De Ferro Do Amapá
The Amapá Railway is a former rail line built by Bethlehem Steel to exploit the manganese deposits in the territory of Amapá (now a state), Brazil. It is , the only railway in the country to use this gauge aside from Line 5 of the São Paulo Metro. The line was also in use for passenger transport. The line was about , spanning from mines near Serra do Navio to the port city of Santana. The rail line stopped transporting ore in 2014, and as of 2020, remains derelict.

Freight Rail
Rail freight transport is the use of railways and trains to transport cargo as opposed to human passengers. A freight train, cargo train, or goods train is a group of freight cars (US) or goods wagons (International Union of Railways) hauled by one or more locomotives on a railway, transporting cargo all or some of the way between the shipper and the intended destination as part of the logistics chain. Trains may haul bulk material, intermodal containers, general freight or specialized freight in purpose-designed cars. Rail freight practices and economics vary by country and region. When considered in terms of ton-miles or tonne-kilometers hauled, energy efficiency can be greater with rail transportation than with other means. Maximum economies are typically realized with bulk commodities (e.g., coal), especially when hauled over long distances. Moving goods by rail often involves transshipment costs, particularly when the shipper or receiver lack direct rail access. These ...

Mineral Deposit
Ore is natural rock or sediment that contains one or more valuable minerals, typically including metals, concentrated above background levels, and that is economically viable to mine and process. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining and is therefore considered an ore. A complex ore is one containing more than one valuable mineral. Minerals of interest are generally oxides, sulfides, silicates, or native metals such as copper or gold. Ore bodies are formed by a variety of geological processes generally referred to as ore genesis and can be classified based on their deposit type. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. Some ores, depending on their composition, may pose ...

Standard-gauge Railways In Brazil
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), international gauge, UIC gauge, uniform gauge, normal gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with about 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, Uzbekistan, and some line sections in Spain. The distance between the inside edges of the heads of the rails is defined to be 1,435 mm except in the United States, Canada, and on some heritage British lines, where it is defined in U.S. customary/ British Imperial units as exactly "four feet eight and one half inches", which is equivalent to 1,435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rail heads) to be used, as the wheels of the rolling stock (locomoti ...

Railway Lines In Brazil
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th c ...

Rail Transport In Brazil
Rail transport in Brazil began in the 19th century and there were many different railway companies. The railways were nationalised, nationalized under RFFSA (Rede Ferroviária Federal, Sociedade Anônima) in 1957. Between 1999 and 2007, RFFSA was broken up and services are now operated by a variety of private and public operators, including Rumo Logística, Companhia Paulista de Trens Metropolitanos and SuperVia. Most railways in Brazil are for freight transportation or urban passenger transportation. Only two inter-city passenger railways survive: the Carajás Railway (connecting Pará and Maranhão) and the Vitória-Minas Railway (connecting Espírito Santo and Minas Gerais), both operated by Vale S.A., Vale S.A.

São Paulo Metro
The São Paulo Metro (, ), commonly called the ''Metrô'', is one of the rapid transit companies serving the city of São Paulo, alongside the Companhia Paulista de Trens Metropolitanos, São Paulo Metropolitan Trains Company (CPTM), Via Quatro and Via Mobilidade, all four forming the largest Transport in São Paulo#Rail transport, metropolitan rail transport network of Latin America. The metro system carries about 4,200,000 passengers a day. The six lines in the metro system operate on of route, serving 91 stations. It is complemented by a network of metropolitan trains operated by CPTM and ViaMobilidade, which serve the city of São Paulo and the Greater São Paulo, São Paulo Metropolitan Region. The systems combined form a long network, all accessible via one single ticket. The metropolitan trains differs from Metro because it also serves other municipalities around São Paulo with larger average distance between stations and freight trains operating in some lines.

Track Gauge
In rail transport, track gauge is the distance between the two rails of a railway track. All vehicles on a rail network must have Wheelset (rail transport), wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A ''loading gauge'' is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A ''structure gauge'' specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. Uses of the term The most common use of the term "track gauge" refers to the transverse distance be ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Manganese
Manganese is a chemical element; it has Symbol (chemistry), symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent, as a rubber additive, and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese is commonly found in labo ...

Passenger Rail
A passenger train is a train used to transport people along a railroad line, as opposed to a freight train that carries goods. These trains may consist of unpowered passenger railroad cars (also known as coaches or carriages) push-pull train, hauled by one or more locomotives, or may be self-propelled; self propelled passenger trains are known as multiple units or railcars. Passenger trains stop at Train station, stations or depots, where passengers may board and disembark. In most cases, passenger trains operate on a fixed Public transport timetable, schedule and have priority over freight trains. Car design and the general safety of passenger trains have dramatically evolved over time, making travel by rail remarkably safe. Some passenger trains, both long-distance and short-distance, use Bilevel car, bi-level (double-decker) cars to carry more passengers per train. Sleeper trains include sleeping cars with beds. Passenger trains hauled by locomotives are more expensive to op ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
