Tramcar
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term ''light rail'', which also includes systems separated from other traffic. Tram vehicles are usually lighter and shorter than main line and rapid transit trains. Most trams use electrical power, usually fed by a pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city streets and diesel in more rural environments. Occasionally, trams also carry freight. Some tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interurban
The interurban (or radial railway in Canada) is a type of electric railway, with tram-like electric self-propelled railcars which run within and between cities or towns. The term "interurban" is usually used in North America, with other terms used outside it. They were very prevalent in many parts of the world before the Second World War and were used primarily for passenger travel between cities and their surrounding suburban and rural communities. Interurban as a term encompassed the companies, their infrastructure, their cars that ran on the rails, and their service. In the United States, the early 1900s interurban was a valuable economic institution, when most roads between towns, many town streets were unpaved, and transportation and haulage was by horse-drawn carriages and carts. The interurban provided reliable transportation, particularly in winter weather, between towns and countryside. In 1915, of interurban railways were operating in the United States and, for a few ...

Bow Collector
A bow collector is one of the three main devices used on tramcars to transfer electric current from the wires above to the tram below. While once very common in continental Europe, it was replaced by the pantograph. Origins The first bow collector was designed by the German engineer Walter Reichel in 1889 and shown at the World Expo in Paris the same year. Reichel worked closely with Ernst Werner von Siemens, and with Siemens being a dominating force in the development of tramways in Europe, the bow collector quickly became the standard solution on the continent for collecting current. Reichel also designed the bow collectors used on the Gross Lichterfelde Tramway, the worlds first public tramway, when it was converted to overhead wire 1891 (it collected current from the rails before that). The Hobart electric tramway system - the first of its kind in the Southern Hemisphere, opened in 1893 - used Siemens cars with very early bow collectors. Many other continental European an ...

Light Rail
Light rail (or light rail transit, abbreviated to LRT) is a form of passenger urban rail transit that uses rolling stock derived from tram technology National Conference of the Transportation Research Board while also having some features from heavy rapid transit. The term was coined in 1972 in the United States as an English equivalent for the German word ''Stadtbahn'', meaning "city railway". From: 9th National Light Rail Transit Conference Different definitions exist in some countries, but in the United States, light rail operates primarily along exclusive Right_of_way#Rail_right_of_way, rights-of-way and uses either individual tramcars or multiple units coupled together, with a lower capacity and speed than a long heavy rail passenger train or rapid transit system. Narrowly defined, light rail transit uses rolling stock that is similar to that of a traditional tram, while operating at a higher capacity and speed, often on an exclusive right-of-way. In broader usage, light ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Third Rail
A third rail, also known as a live rail, electric rail or conductor 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 track (rail transport), railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third-rail systems are usually supplied with direct current. Modern tram systems with street running avoid the electrical injury risk of the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge, dual-gauge railways. The system is generally associated with a low voltage (rarely above 750 V) and is far less used for main lines than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Rail Transit
Urban rail transit is a wide term for various types of local rail systems providing passenger service within and around urban or suburban areas. The set of urban rail systems can be roughly subdivided into the following categories, which sometimes overlap because some systems or lines have aspects of multiple types. Types Tram A ''tram'', ''streetcar'', or ''trolley'' system is a rail-based transit system that runs mainly or completely along streets (with street running), with a relatively-low capacity and frequent stops; however, modern trams have a greater passenger capacity than traditional trams. Passengers usually board at the street or curb level, but low-floor trams may allow level boarding. Longer-distance lines are called ''interurbans'' or ''radial railways''. Modern trams also operate as self-propelled trains coupled through a multiple unit instead of individual trams and are often included within the broader term light rail; however, they differ in that trams ...

Swansea And Mumbles Railway
The Swansea and Mumbles Railway was the venue for the world's first passenger horsecar railway service, located in Swansea, Wales, United Kingdom. Originally built under an act of Parliament, the Oystermouth Railway or Tramroad Act 1804, to move limestone from the quarries of Mumbles to Swansea and to the markets beyond, it carried the world's first fare-paying railway passengers under an agreement effective from 25 March 1807. It later moved from horse power to steam locomotion, and was finally converted to electric power, using the largest tram cars ever built for service in Britain, before closing in January 1960, in favour of motor buses. At the time of the railway's closure, it was claimed to have been the world's longest serving railway, although this distinction has to be qualified because other railways which were used solely for goods traffic (e.g. the Middleton Railway in Leeds, Yorkshire, dating from 1758) had been operating for longer.

Tramway Track
Tramway track is used on tramways or light rail operations. As with standard rail tracks, tram tracks have two parallel steel rails, the distance between the heads of the rails being the track gauge. When there is no need for pedestrians or road vehicles to traverse the track, conventional flat-bottom rail is used. However, when such traffic exists, such as in urban streets, grooved rails are used. Tram rails can be placed on several surfaces, such as on ground over which track ballast topped by sleepers (US: ties) and flat-bottom rails are laid – as with railway tracks – or, for street running, with grooved rails usually embedded into a concrete pavement. In some places, tracks are laid into grass turf surfaces; they are known as '' green track'', ''grassed track'' or ''track in lawn''. History Tramway tracks have been in existence since the mid-16th century. They were made of wood, but during the late 18th century iron and later steel came into use and then ...

Tram-train
A tram-train or dual-system tram is a type of light rail vehicle that both meets the standards of a light rail system, and also national mainline standards. Tramcars are adapted to be capable of running on streets like an urban tramway but also be permitted operation alongside mainline trains. This allows services that can utilise both existing urban light rail systems and mainline railway networks and stations. It combines the urban accessibility of a tram or light rail with a mainline train's greater speed in the suburbs. The modern tram-train concept was pioneered by the German city of Karlsruhe in the late 1980s, resulting in the creation of the Karlsruhe Stadtbahn. This concept is often referred to as the Karlsruhe model, and it has since been adopted in other cities such as Mulhouse in France and in Kassel, Nordhausen and Saarbrücken in Germany. An inversion of the concept is a train-tram – a mainline train adapted to run on-street in an urban tramway, also know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: Cast iron#White cast iron, white cast iron has its carbon combined into an iron carbide named cementite, which is very hard, but brittle, as it allows cracks to pass straight through; Grey iron, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and Ductile iron, ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable iron, malleable cast irons. With its relatively low melting point, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plateway
A plateway is an early kind of railway, tramway or wagonway, where the rails are made from cast iron. They were mainly used for about 50 years up to 1830, though some continued later. Plateways consisted of L-shaped rails, where the flange on the rail guides the wheels, in contrast to edgeways, where flanges on the wheels guide them along the track. Plateways were originally horsedrawn but, later on, cable haulage and small locomotives were sometimes used. The plates of the plateway were made of cast iron, often fabricated by the ironworks that were their users. On most lines, that system was replaced by rolled wrought iron (and later steel) "edge rails" which, along with realignment to increase the radius of curves, converted them into modern railways, better suited to locomotive operation. Plateways were particularly favoured in South Wales and the Forest of Dean, in some cases replacing existing edge rails. Other notable plateways included the Hay Railway, the Glo ...
