Transport In Venezuela
Transport in Venezuela revolves around a system of highways and airports. Venezuela is connected to the world primarily via air ( Venezuela's airports include the Simón Bolívar International Airport near Caracas and La Chinita International Airport near Maracaibo) and sea (with major seaports at La Guaira, Maracaibo and Puerto Cabello). In the south and east the Amazon rainforest region has limited cross-border transport; in the west, there is a mountainous border of over shared with Colombia. The Orinoco River is navigable by oceangoing vessels up to 400 km inland, and connects the major industrial city of Ciudad Guayana to the Atlantic Ocean. Venezuela has a limited national railway system, which has no active rail connections to other countries. Several major cities have metro systems; the Caracas Metro has been operating since 1983. The Maracaibo Metro and Valencia Metro were opened more recently. Venezuela has a road network of around 100,000 km (placing it aro ...

Standard Gauge
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 and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. 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 rails) to be used. Different railways used different gauges, and where rails of different gauge met – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

25 KV AC Railway Electrification
Railway electrification systems using alternating current (AC) at are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60Hz), which simplifies traction substations. The development of 25kV AC electrification is closely connected with that of successfully using utility frequency. This electrification is ideal for railways that cover long distances or carry heavy traffic. After some experimentation before World War II in Hungary and in the Black Forest in Germany, it came into widespread use in the 1950s. One of the reasons why it was not introduced earlier was the lack of suitable small and lightweight control and rectification equipment before the development of solid-state rectifiers and related technology. Another reason was the increased clearance distances required where it ran under bridges and in tunnels, which would have required major civil engineering in order to provide the increased clearance t ...

Railway Air Brake
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, called the ''straight air system'', compressed air pushes on a piston in a cylinder. The piston is connected through mechanical linkage to brake shoes that can rub on the train wheels, using the resulting friction to slow the train. Th ...

Coupling (railroad)
A coupling (or a coupler) is a mechanism typically placed at each end of a railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Buffers and chain The basic type of coupling on railways following the British tradition is the bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railroad Of Cúcuta
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...

Rail Transport In Brazil
Rail transport in Brazil began in the 19th century and there were many different railway companies. The railways were nationalised 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 América Latina 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 to Minas Railway (connecting Espírito Santo and Minas Gerais). Track gauge The rail system in Brazil operates on three rail gauges: * Broad gauge: gauge * Metre gauge: gauge * Standard gauge: gauge: ** line 5 of the São Paulo Metro, so that it can use "off the shelf" equipment. ** Estrada de Ferro do Amapá in the middle of the Amazon Rainforest also used s ...

Transport In Brazil
Transport infrastructure in Brazil is characterized by strong regional differences and lack of development of the national rail network. Brazil's fast-growing economy, and especially the growth in exports, will place increasing demands on the transport networks. However, sizeable new investments that are expected to address some of the issues are either planned or in progress. It is common to travel domestically by air because the price is low. Brazil has the second highest number of airports in the world, after the USA. Railways The Brazilian railway network has an extension of about . It is basically used for transporting ores. Usually, the railway sector was treated in a secondary way in Brazil, due to logistical, economic or political difficulties to install more railways. The Brazilian railroad system had a great expansion between 1875 and 1920. The heyday of the railway modal was interrupted during the Getúlio Vargas government, which prioritized the road modal.
