Light rail often makes closely-spaced stops right in downtown, and may thus serve a “streetcar” function there, but it does this mainly for the purpose of providing good access to people who want to use its higher-speed segments. I refer to streetcars/trams only when I mean local-stop services, designed to do pretty much what local buses do. The rail profile is the cross sectional shape of a railway rail, perpendicular to its length. Early rails were made of wood, cast iron or wrought iron. All modern rails are hot rolled steel with a cross section (profile) approximate to an I-beam, but asymmetric about a horizontal axis (however see grooved rail below). The freeplay between each wheel and the rail it is riding on is therefore ¼ inch [6.35 millimeters]. Readers should compare Figure 4.2.2 against Figure 4.2.1 to see the differences between railroad and transit wheel gauge practice. A light rail transit (LRT) system is an urban rail transit system with a "light" passenger capacity compared to heavy rail and metro systems. Its operating characteristics are that it uses railcars , called light rail vehicles (LRVs), operating singly or in short multiple unit trains on fixed rails in a right-of-way that is not necessarily Nottingham Express Transit ( NET) is a 20-mile (32 km) [4] tram system in Nottingham, England. The system opened to the public on 9 March 2004 and a second phase, that more than doubled the size of the total system, opened on 25 August 2015, having been initially planned to open two years earlier. The network is operated and maintained by Light rail or light rail transit (LRT) is a form of urban rail public transportation that generally has a lower capacity and lower speed than heavy rail and metro systems, but higher capacity and higher speed than traditional street-running tram systems. The term is typically used to refer to rail systems with rapid transit-style features that Light rail, tram, streetcar, trolley, etc are pretty much synonymous. They are all self powered (usually electric) rail vehicles that may have sections that run in the street. Heavy rail is usually your typical passenger train (with a locomotive) or a subway like in NYC or the London Underground. A medium-capacity system ( MCS ), also known as light rapid transit or light metro, is a rail transport system with a capacity greater than light rail, but less than typical heavy-rail rapid transit. [1] MCS's trains are usually 1–4 cars. Most medium-capacity rail systems are automated or use light rail type vehicles. App Vay Tiền.
