Tram Stops In Melbourne
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Contact Shoe
A current collector (often called a "pickup") is a device used in trolleybuses, trams, electric locomotives and Electric multiple unit, EMUs to carry electric power (Electric current, current) from overhead lines, electric third rails, or ground-level power supply, ground-level power supplies to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for rails are mounted on the bogies. Typically, electric current connectors have one or more spring-loaded arms that press a collector or contact shoe against the rail or overhead wire. As the vehicle moves, the contact shoe slides along the wire or rail to draw the electricity needed to run the vehicle's motor. The current collector arms are electrical conductivity, electrically conductive but mounted Electrical insulation, insulated on the vehicle's roof, side or base. An insulated cable connects the collector with the switch, transformer or Electric motor, motor. The Rail profile, stee ... [...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 ...

Mine Cart
A minecart, mine cart, or mine car (or more rarely mine trolley or Campbeltown and Machrihanish Light Railway#Freight stock, mine hutch), is a type of rolling stock found on a mine railway, used for transporting ore and materials procured in the process of traditional mining. Minecarts are seldom used in modern operations, having largely been superseded in underground operations (especially coal mines) by more efficient belt conveyor systems that allow machines such as Longwall mining#Equipment, longwall shearers and continuous miners to operate at their full capacity, and above ground by large haul truck, dumpers. Terminology Throughout the world, there are different titles for mine carts. In South Africa, a minecart is referred to as a ; or :af:koekepan, koekepan. In German language, German, it is called (alternative spelling ). In Wales, minecarts are known as drams. In the U.S. and elsewhere, the term skip – or skip wagon (older spelling: ''waggon'') – is used. (Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wagonway
A wagonway (or waggonway; also known as a horse-drawn railway, or horse-drawn railroad) was a method of rail transport, railway transportation that preceded the steam locomotive and used horses to haul wagons. The terms plateway and tramway (industrial), tramway were also used. The advantage of wagonways was that far bigger loads could be transported with the same power compared to horse haulage along roads. Ancient systems The earliest evidence is of the long ''Diolkos'' paved trackway, which transported boats across the Isthmus of Corinth in Greece from around 600 BC. Wheeled vehicles pulled by men and animals ran in grooves in limestone, which provided the track element, preventing the wagons from leaving the intended route. The Diolkos was in use for over 650 years, until at least the 1st century AD. Paved trackways were later built in Roman Egypt. Wooden rails Such an operation was illustrated in Germany in 1556 by Georgius Agricola (image left) in his work De re met ...

Total Cost Of Ownership
Total cost of ownership (TCO) is a financial estimate intended to help buyers and owners determine the direct and indirect costs of a product or service. It is a management accounting concept that can be used in full cost accounting or even ecological economics where it includes social costs. For manufacturing, as TCO is typically compared with doing business overseas, it goes beyond the initial manufacturing cycle time and cost to make parts. TCO includes a variety of cost of doing business items, for example, ship and re-ship, and opportunity costs, while it also considers incentives developed for an alternative approach. Incentives and other variables include tax credits, common language, expedited delivery, and customer-oriented supplier visits. Use of concept TCO, when incorporated in any financial benefit analysis, provides a cost basis for determining the total economic value of an investment. Examples include: return on investment, internal rate of return, economic v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolling Resistance
Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the Motion (physics), motion when a body (such as a ball, tire, or wheel) Rolling, rolls on a surface. It is mainly caused by Plasticity (physics), non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc., is recovered when the pressure is removed. Two forms of this are hysteresis losses (see rolling resistance#Primary cause, below), and permanent plastic deformation, (plastic) deformation of the object or the surface (e.g. soil). Note that the frictional contact mechanics, slippage between the wheel and the surface also results in energy dissipation. Although some researchers have included this term in rolling resistance, some suggest that this dissipation term should be treated separately from rolling resistance because it is due to the applied torque to the wheel and the resultant slip between the wheel and ground, which is called ...

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 ...
