Buffers And Chain Coupler
Buffers and chain couplers (or couplings) – also known as "buffers and screw", "screw", and "screwlink" – are the de facto International Union of Railways (UIC) standard railway coupling used in the EU and UK, and on some railways in other parts of the world, such as in South America and India, on older rolling stock. Buffers and chain couplers are an assembly of several devices: buffers, hooks and links, or turnbuckle screws. On the modern version of the couplers, rail vehicles are mated by manually connecting the end link of one chain which incorporates a turnbuckle screw into the towing hook of the other wagon, drawing together and slightly compressing the Buffer (rail transport), buffer pairs, one left and one right on each headstock. That limits slack, and lessens Shunting (rail), shunting shocks in moving trains. By contrast, vehicles fitted with the semi-automatic Janney coupler, Janney Type E coupler can experience significant jarring during mating and shunting. V ...

International Union Of Railways
The International Union of Railways (, UIC) is an international rail transport industry body based in Paris. History The railways of Europe had originated during the nineteenth century as many separate concerns across numerous nations; this led to disparate and conflicting standards emerging and thus onto incompatibility. One prominent example was the British Gauge War, during which different rail transport, railway companies were laying different track gauges across Great Britain, causing inefficiency wherever a break of gauge occurred, prior to an Regulating the Gauge of Railways Act 1846, Act of Parliament the issue in 1846 by establishing one standard gauge of . The early effort towards standardisation somewhat influenced railways aboard as well, however various other track gauges persisted and developed across the world; even through to the twenty first century, incompatible track gauges, let alone other issues, persisted to hinder interoperability efforts.

Eritrean Railway
The Eritrean Railway is the only railway system in Eritrea. It was constructed between 1887 and 1932 during the Italian Eritrea colony and connects the port of Massawa with Asmara. Originally it also connected to Bishia. The line was partly damaged by warfare in subsequent decades, but was rebuilt in the 1990s. Vintage equipment is still used on the line. Main railway line Characteristics The railway was built during Italian Eritrea in order to connect Massawa and Asmara, the main cities of Eritrea. In the 1930s Italian leader Benito Mussolini wanted to reach Kassala in Sudan, but his war to conquer Ethiopia and create the Italian Empire stopped the enlargement to Agordat and Bishia. After damage suffered by the railway during World War II, the section between Massawa and Asmara was dismantled partially and was only rebuilt in the 1990s by the Eritrean authorities. The railway is narrow-gauge and is being rebuilt after the devastation wreaked upon it by the war of independen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 High-speed rail in Russia, those in Russia, High-speed rail in Finland, Finland, High-speed rail in Uzbekistan, Uzbekistan, and some line sections in High-speed rail in Spain, 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 Imperial and US customary measurement systems, U.S. customary/Imperial units, British Imperial units as exactly "four feet eight and one half inches", which is equivalent to 1,435.1mm.

Railway Coupling
A coupling or coupler is a mechanism, typically located at each end of a rolling stock, rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train. Throughout the history of rail vehicles, a variety of coupler designs and types have been developed worldwide. Key design considerations include strength, reliability, easy and efficient handling, and operator safety. Automatic couplers engage automatically when the cars are pushed together. Modern versions not only provide a mechanical connection, but can also couple brake lines and data lines. Different countries use different types of couplers. While North American railroads and China use Janney couplers, railroads in the former Soviet Union use SA3 couplers and the European countries use Scharfenberg coupler, Scharfenberg and Buffers and chain coupler, screw ...

Bogie Exchange
A bogie ( ) (or truck in North American English) comprises two or more wheelsets (two wheels on an axle), in a frame, attached under a vehicle by a pivot. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as for a dolly in a road train or in railway bogie exchange). It may include suspension components within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as are most bogies of tracked vehicles). It may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). Although ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.

Rail Transport In Great Britain
The railway system in Great Britain is the oldest railway system in the world. The first locomotive-hauled public railway opened in 1825, which was followed by an era of rapid expansion. Most of the track is managed by Network Rail, which in 2024 had a network of of standard-gauge lines, of which were Railway electrification in Great Britain, electrified. In addition, some cities have separate metro, light rail and tram systems, among them the historic London Underground and the Glasgow Subway. There are also many List of British heritage and private railways, private railways, some of them British narrow gauge railways, narrow-gauge, which are primarily short lines for tourists. The main rail network is connected with that of continental Europe by the Channel Tunnel and High Speed 1, opened in 1994 and 2007 respectively. In 2024, there were 1.612 billion journeys on the National Rail network, making the British network the List of countries by rail usage, fifth most ...

Iberian Gauge
Iberian gauge (, ) is a track gauge of , most extensively used by the railways of Spain and Portugal. A broad gauge, it is the second-widest gauge in regular use anywhere in the world, with only Indian gauge railways, , being wider (by ). As finally established in 1955, the Iberian gauge is a compromise between the similar, but slightly different, gauges adopted as respective national standards in Spain and Portugal in the mid-19th century. The main railway networks of Spain were initially constructed to a gauge of six Castilian feet. Those of Portugal were instead built to a and later railways to a gauge of five Portuguese feet – close enough to allow interoperability with Spanish railways. Standard gauge Since the beginning of the 1990s new high-speed passenger lines in Spain have been built to the international standard gauge of , to allow these lines to link to the European high-speed network.

Narrow Gauge Railway
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge (distance between the rails) narrower than . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with Minimum railway curve radius, tighter curves, smaller structure gauges, and lighter Rail profile, rails; they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard: Ja ...

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] |
Minimum Railway Curve Radius
The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions. It has an important bearing on construction costs and operating costs and, in combination with superelevation (difference in elevation of the two rails) in the case of train tracks, determines the maximum safe speed of a curve. The minimum radius of a curve is one parameter in the design of railway vehicles as well as trams; monorails and automated guideways are also subject to a minimum radius. History The first proper railway was the Liverpool and Manchester Railway, which opened in 1830. Like the tram roads that had preceded it over a hundred years, the L&M had gentle curves and gradients. Reasons for these gentle curves include the lack of strength of the track, which might have overturned if the curves were too sharp causing derailments. The gentler the curves, the greater the visibility, thus boosting safety via increa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stuttgart Central Station
Stuttgart Hauptbahnhof (; ) is the primary railway station in the city of Stuttgart, the state capital of Baden-Württemberg, in southwestern Germany. It is the largest regional and long-distance railway station in Stuttgart, the main node of the Stuttgart S-Bahn network, and, together with the station at Charlottenplatz, it is the main node of the Stuttgart Stadtbahn. Located at the northeastern end of the ''Königstraße'', the main pedestrian zone of the city centre, the main line station is a terminus, whilst the subterranean S-Bahn and Stadtbahn stations are through-stations. The station is well known for its 12-storey tower with a large, rotating and illuminated Mercedes-Benz star insignia on top; the tower and station building are city landmarks. Currently, as part of the Stuttgart 21 project, which is also very controversial among the population, the train station is being converted from an above-ground terminus station into an underground through station.
