Light Rail In The United States
The United States has 27 light-rail systems, as counted by the Light Rail Transit Association, not including streetcar systems. Six of them (Boston, Los Angeles, Philadelphia, Portland (Oregon), San Diego, and San Francisco) achieve more than 30 million unlinked passenger transits per year. Light-rail systems are typically designed to carry fewer passengers than heavy-rail systems like commuter rail or rapid transit (subway). They can operate in mixed traffic (street running) or on routes that are not entirely grade-separated. They typically take one of four forms: "first-generation" legacy systems, "second-generation" modern light-rail systems, streetcars, and hybrid rail systems (light rail with some commuter-rail features). All use similar technologies, and some systems blur the lines between the different forms. History From the mid-19th century onwards, horse-drawn trams (or horsecars) were used in cities around the world. The St. Charles Avenue Line of New Orlean ...

Street Railway
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which Rolling stock, vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated Right-of-way (property access), 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 (railway), main line and rapid transit trains. Most trams use electrical power, usually fed by a Pantograph (transport), 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 stre ...

Alberta
Alberta is a Provinces and territories of Canada, province in Canada. It is a part of Western Canada and is one of the three Canadian Prairies, prairie provinces. Alberta is bordered by British Columbia to its west, Saskatchewan to its east, the Northwest Territories to its north, and the U.S. state of Montana to its south. Alberta and Saskatchewan are the only two landlocked Canadian provinces. The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly humid continental climate, continental climate, but seasonal temperatures tend to swing rapidly because it is so arid. Those swings are less pronounced in western Alberta because of its occasional Chinook winds. Alberta is the fourth largest province by area, at , and the fourth most populous, with 4,262,635 residents. Alberta's capital is Edmonton; its largest city is Calgary. The two cities are Alberta's largest Census geographic units ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edmonton
Edmonton is the capital city of the Provinces and territories of Canada, Canadian province of Alberta. It is situated on the North Saskatchewan River and is the centre of the Edmonton Metropolitan Region, which is surrounded by Central Alberta, Alberta's central region, and is in Treaty 6, Treaty 6 territory. It anchors the northern end of what Statistics Canada defines as the "Calgary–Edmonton Corridor". The area that later became the city of Edmonton was first inhabited by First Nations in Alberta, First Nations peoples and was also a historic site for the Métis in Alberta, Métis. By 1795, many trading posts had been established around the area that later became the Edmonton census metropolitan area. "Fort Edmonton", as it was known, became the main centre for trade in the area after the 1821 merger of the Hudson's Bay Company and the North West Company. It remained sparsely populated until the Canadian acquisition of Rupert's Land in 1870, followed eventually by the arri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Diego Trolley
The San Diego Trolley is a light rail system serving San Diego County, California. The trolley's operator, San Diego Trolley, Inc. , is a subsidiary of the San Diego Metropolitan Transit System (MTS). The trolley operates as a critical component of MTS, with connections to and integrated travel tickets with the local bus systems. The trolley system serves 62 stations, over about of route, using four primary lines (Blue, Orange, Green, and Copper) that operate daily, and a "downtown loop" heritage streetcar line (Silver) that operates on holidays. There is one downtown station where all major lines connect, and thirteen other stations that provide transfers to a second line (two of these also provide connections to commuter rail systems). The trolley began service on July 26, 1981, making it the oldest of the second-generation light rail systems in the United States, and the success of the system helped spark a nationwide revival of light rail. In , the trolley had the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stadtbahn
(; German for 'city railway'; plural ) is a German word referring to various types of urban rail transport. One type of transport originated in the 19th century, firstly in Berlin and followed by Vienna, where rail routes were created that could be used independently from other traffic. In the 1960s and 1970s, ''Stadtbahn'' networks were created again but now by upgrading tramways or light rail lines. This process includes adding segments built to rapid transit standards – usually as part of a process of conversion to a metro railway – mainly by the building of metro-grade tunnels in the central city area. In the first years after the opening of the tunnel sections, often regular trams vehicles (but adapted for tunnel service) were used. These trams were followed by specially designed vehicles like the Stadtbahn B series. By the 1980s virtually all cities had abandoned the long-term goal of establishing a full-scale metro system due to the excessive costs associated with ...

Great American Streetcar Scandal
The General Motors streetcar conspiracy refers to the convictions of General Motors (GM) and related companies that were involved in the monopolizing of the sale of buses and supplies to National City Lines (NCL) and subsidiaries, as well as to the allegations that the defendants conspired to own or control transit systems, in violation of Section 1 of the Sherman Antitrust Act. This suit created lingering suspicions that the defendants had in fact plotted to dismantle streetcar systems in many cities in the United States as an attempt to monopolize surface transportation. Between 1938 and 1950, National City Lines and its subsidiaries, American City Lines and Pacific City Lines—with investment from GM, Firestone Tire, Standard Oil of California (through a subsidiary), Federal Engineering, Phillips Petroleum, and Mack Trucks—gained control of additional transit systems in about 25 cities. Systems included St. Louis, Baltimore, Los Angeles, and Oakland. NCL often conver ... [...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.
