97-524: The Srinagar Metro is a light rail transit planned for the city of Srinagar , Jammu and Kashmir . The plans for the Srinagar Metro have been finalised with the work expected to start once the project gets nod from union cabinet. The proposed network will have two corridors. Each corridor of Srinagar metro will have 12 stations each with the total cost expected to be ₹5,559 crore. Former Delhi Metro Rail Corporation (DMRC) chief E. Sreedharan , who
194-724: A "light rail" vehicle (it is a heavy rail vehicle), and is only included for comparison purposes. Low-floor LRVs have the advantage of a low-floor design, allowing them to load passengers directly from low-rise platforms that can be little more than raised curbs. High-floor light rail systems also exist, featuring larger stations. Historically, the track gauge has had considerable variations, with narrow gauge common in many early systems. However, most light rail systems are now standard gauge . Older standard-gauge vehicles could not negotiate sharp turns as easily as narrow-gauge ones, but modern light rail systems achieve tighter turning radii by using articulated cars . An important advantage of
291-697: A 25 km line in Srinagar and a 23 km line in Jammu. The administration's decision to opt for the MetroLite system, with its lower capital and operational costs, reflects the unique requirements and feasibility of the region. The implementation of these metro lines is expected to enhance connectivity and provide commuters with a more convenient and efficient mode of transportation. Two elevated corridors have been planned in Phase 1, with an estimated ridership of 200,000 by
388-458: A bus, there will be even more capacity when there is a combination of cars and light rail. Table 3 shows an example of peak passenger capacity. The cost of light rail construction varies widely, largely depending on the amount of tunneling and elevated structures required. A survey of North American light rail projects shows that costs of most LRT systems range from $ 15 million to over $ 100 million per mile. Seattle's new light rail system
485-403: A chaotic breakdown inflow and a dramatic drop in speed (a traffic jam ) if they exceed about 2,000 vehicles per hour per lane (each car roughly two seconds behind another). Since most people who drive to work or on business trips do so alone, studies show that the average car occupancy on many roads carrying commuters is only about 1.5 people per car during the high-demand rush hour periods of
582-1142: A common right-of-way (however, Link converted to full separation in 2019). Some systems, such as the AirTrain JFK in New York City, the DLR in London, and Kelana Jaya Line in Kuala Lumpur , have dispensed with the need for an operator. The Vancouver SkyTrain was an early adopter of driverless vehicles, while the Toronto Scarborough rapid transit operated the same trains as Vancouver, but used drivers. In most discussions and comparisons, these specialized systems are generally not considered light rail but as light metro systems. Around Karlsruhe , Kassel , and Saarbrücken in Germany, dual-voltage light rail trains partly use mainline railroad tracks, sharing these tracks with heavy rail trains. In
679-535: A detailed project including feasibility and financial viability. The Detailed Project Report (DPR) was completed by RITES and it was submitted to the Ministry of Home and Urban Affairs. The two projects in Jammu and Srinagar respectively were estimated to cost around ₹10,559 crores, with each project expected to be completed by 2024 if the Union Cabinet gives the nod. Lieutenant governor, Manoj Sinha said that
776-500: A fully separated U-Bahn (metro) network independent of other forms of transport, others planned for a lesser degree of separation, one that would accommodate additional tram-like sections in the long run. For both the interim and the long-term based concepts, the following terms came into use U-Straßenbahn or Untergrund-Straßenbahn ('underground tramway', abbreviated as U-Strab , Schnellstraßenbahn ('rapid tramway'), and finally Stadtbahn . An older term already used in
873-416: A light rail train may have three to four cars of much larger capacity in one train under the control of one driver, or no driver at all in fully automated systems, increasing the labor costs of BRT systems compared to LRT systems. BRT systems are also usually less fuel-efficient as they use non-electrified vehicles. The peak passenger capacity per lane per hour depends on which types of vehicles are allowed on
970-435: A live rail. In outer areas, the trams switch to conventional overhead wires . The Bordeaux power system costs about three times as much as a conventional overhead wire system and took 24 months to achieve acceptable levels of reliability, requiring the replacement of all the main cables and power supplies. Operating and maintenance costs of the innovative power system still remain high. However, despite numerous service outages,
1067-543: A longer distance. Light rail cars are often coupled into multiple units of two to four cars. Light rail systems may also exhibit attributes of heavy rail systems, including having downtown subways, as in San Francisco and Seattle . Light rail is designed to address a gap in interurban transportation between heavy rail and bus services, carrying high passenger numbers more quickly than local buses and more cheaply than heavy rail. It serves corridors in which heavy rail

#17327730214381164-642: A more diverse range of design characteristics than LRT, depending on the demand and constraints that exist, and BRT using dedicated lanes can have a theoretical capacity of over 30,000 passengers per hour per direction (for example, the Guangzhou Bus Rapid Transit system operates up to 350 buses per hour per direction). For the effective operation of a bus or BRT system, buses must have priority at traffic lights and have their dedicated lanes, especially as bus frequencies exceed 30 buses per hour per direction. The higher theoretical of BRT relates to
1261-407: A result, has many of the operating characteristics of a metro system rather than a light rail system. A capacity of 1,350 passengers per train is more similar to the heavy rail than light rail. Bus rapid transit (BRT) is an alternative to LRT and many planning studies undertake a comparison of each mode when considering appropriate investments in transit corridor development. BRT systems can exhibit
1358-491: A square containing the word 'Tram'. Although the design is the same nationwide, the colour varies from city to city to match local public transport operators' systems of colour-coding. The logo is part of the 'S logo scheme' initially developed by Berlin public transport operator BVG , based on the established logos for urban metro ('U', for U-Bahn ) and suburban metro ('S', for S-Bahn ) and including bus ('Bus') and ferry ('F', for Fähre ) operations. The logo also helped spread
1455-534: A top speed of 55–71.5 miles per hour (88.51–115.1 km/h) depending on the system, while the trains on the all-underground Montreal Metro can only reach a top speed of 72 kilometres per hour (44.74 mph). LACMTA light rail vehicles have higher top and average speeds than Montreal Metro or New York City Subway trains. Many light rail systems—even fairly old ones—have a combination of both on- and off-road sections. In some countries (especially in Europe), only
1552-481: A tramway, a light metro, and, in a narrow sense, rapid transit. This is especially common in the United States, where there is not a popularly perceived distinction between these different types of urban rail systems. The development of technology for low-floor and catenary-free trams facilitates the construction of such mixed systems with only short and shallow underground sections below critical intersections as
1649-470: Is a generic international English phrase for types of rail systems using modern streetcars/trams, which means more or less the same thing throughout the English-speaking world . Light rail systems can range from trams runnig in streets along with other traffic, to semi-metro systems having portions of grade separated track. People movers are even "lighter", in terms of capacity. Monorail
1746-575: Is a separate technology that has been more successful in specialized services than in a commuter transit role. The use of the generic term light rail avoids some serious incompatibilities between British and American English . The word tram , for instance, is generally used in the UK and many former British colonies to refer to what is known in North America as a streetcar , but in North America tram can instead refer to an aerial tramway , or, in
1843-602: Is a significant amount of overlap between the technologies; similar rolling stock may be used for either, and it is common to classify streetcars or trams as a subcategory of light rail rather than as a distinct type of transportation. However, some distinctions can be made, though systems may combine elements of both. Low-floor light rail lines tend to follow a reserved right-of-way and with trains receiving priority at intersections, and tend not to operate in mixed traffic, enabling higher operating speeds. Light rail lines tend to have less frequent stops than tramways, and operate over
1940-542: Is achieved by giving the trams their own right of way on the surface. Stadtbahn in this wider meaning is thus not a clearly defined concept, but a vague one linked to a set of attributes, much in the same way that Straßenbahn ('tram') is linked to very different, sometimes mutually incompatible attributes. A system that is called Stadtbahn today may not have all of the Stadtbahn attributes: barrier-free access, higher cruising speed than tramways, doors on both sides of
2037-563: Is by far the most expensive in the US, at $ 179 million per mile, since it includes extensive tunneling in poor soil conditions, elevated sections, and stations as deep as 180 feet (55 m) below ground level. This results in costs more typical of subways or rapid transit systems than light rail. At the other end of the scale, four systems (Baltimore, Maryland; Camden, New Jersey; Sacramento, California; and Salt Lake City, Utah) incurred construction costs of less than $ 20 million per mile. Over

#17327730214382134-426: Is especially important for wheelchair access, as narrower gauges (e.g. metre gauge) can make it challenging or impossible to pass the tram's wheels. Furthermore, standard-gauge rolling stock can be switched between networks either temporarily or permanently, and both newly built and used standard-gauge rolling stock tends to be cheaper to buy, as more companies offer such vehicles. Overhead lines supply electricity to
2231-502: Is expensive. Similarly, the most expensive US highway expansion project was the " Big Dig " in Boston, Massachusetts, which cost $ 200 million per lane mile for a total cost of $ 14.6 billion. A light rail track can carry up to 20,000 people per hour as compared with 2,000–2,200 vehicles per hour for one freeway lane. For example, in Boston and San Francisco, light rail lines carry 9,600 and 13,100 passengers per hour, respectively, in
2328-575: Is hard to distinguish between what is called light rail, and other forms of urban and commuter rail. A system described as a light rail in one city may be considered to be a streetcar or tram system in another. Conversely, some lines that are called "light rail" are very similar to rapid transit ; in recent years, new terms such as light metro have been used to describe these medium-capacity systems. Some "light rail" systems, such as Sprinter , bear little similarity to urban rail, and could alternatively be classified as commuter rail or even inter-city rail. In
2425-559: Is impractical. Light metro systems are essentially hybrids of light rail and rapid transit. Metro trains are larger and faster than light rail trains, with stops being further apart. Many systems have mixed characteristics. Indeed, with proper engineering, a rail line could run along a street, then go underground, and then run along an elevated viaduct. For example, the Los Angeles Metro Rail 's A Line "light rail" has sections that could alternatively be described as
2522-484: Is one of the highest capacity ones, having been upgraded in a series of expansions to handle 40,000 passengers per hour per direction, and having carried as many as 582,989 passengers in a single day on its Line 1 . It achieves this volume by running four-car trains with a capacity of up to 1,350 passengers each at a frequency of up to 30 trains per hour. However, the Manila light rail system has full grade separation and as

Jammu and Kashmir state government has planned to introduce a metro rail system in cities of Srinagar and Jammu which respectively serve as Summer and winter capital of the state. The government had hired an infrastructure development enterprise, RITES to conduct a traffic analysis. The government has planned to approach Delhi Metro Rail Corporation for
2716-407: 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 use, it includes tram-like operations mostly on streets. A few light rail networks have characteristics closer to rapid transit or even commuter rail , yet only when these systems are fully grade-separated are they referred to as light metros . The term light rail
2813-546: Is that in systems like Cologne-Bonn's the tracks were converted for Stadtbahn use by changing the electrification, while in Karlsruhe the trains were equipped to run on both types of track. Straßenbahn (tram) and Stadtbahn in the Karlsruhe region are differentiated more by the nature of their city-border crossings only, and not by the technical dimension (Dual-System Light Rail Vehicles). Only those services that extend into
2910-542: The Cádiz TramBahia , where trams share track with commuter and long-distance trains from the main terminus in the city and curve off to serve cities without a railway connection. Some of the issues involved in such schemes are: There is a history of what would now be considered light rail vehicles operating on heavy rail rapid transit tracks in the US, especially in the case of interurban streetcars . Notable examples are Lehigh Valley Transit trains running on
3007-758: The London Underground and the New York City Subway . Conventional rail technologies including high-speed , freight, commuter , and rapid transit urban transit systems are considered "heavy rail". The main difference between light rail and heavy rail rapid transit is the ability for a light rail vehicle to operate in mixed traffic if the routing requires it. The world's first electric tram operated in Sestroretsk near Saint Petersburg , Russia , invented and operated on an experimental basis by Fyodor Pirotsky in 1880. The first tramway

3104-637: The Netherlands , this concept was first applied on the RijnGouweLijn . This allows commuters to ride directly into the city center, rather than taking a mainline train only as far as a central station and then having to change to a tram. In France, similar tram-trains are planned for Paris, Mulhouse , and Strasbourg ; further projects exist. In some cases, tram trains use previously abandoned or lightly used heavy rail lines in addition to or instead of still in use mainline tracks. In 2022, Spain opened

Light rail is different from the British English term light railway , long-used to distinguish railway operations carried out under a less rigorous set of regulations using lighter equipment at lower speeds from mainline railways. Light rail
3298-703: The Philadelphia and Western Railroad high-speed third rail line (now the Norristown High-Speed Line ). Such arrangements are almost impossible now, due to the Federal Railroad Administration refusing (for crash safety reasons) to allow non-FRA compliant railcars (i.e., subway and light rail vehicles) to run on the same tracks at the same times as compliant railcars, which includes locomotives and standard railroad passenger and freight equipment. Notable exceptions in
3395-621: 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 converting the tramways. Most Stadtbahn systems are now a mixture of tramway-like operations in suburban and peripheral areas and a more metro-like mode of operation in city centres, with underground stations. This 20th century Stadtbahn concept eventually spread from Germany to other European countries, where it became known as pre-metro . The term Stadtbahn first arose in
3492-505: The direct current of Straßenbahn lines (750 V) could also draw power from the 15-kV- alternating current from normal DB catenary. In Karlsruhe this network reached as far as Heilbronn , 84 kilometres (52 mi) away, where a Stadtbahn network was created going out from this line. Both in Karlsruhe and in Heilbronn the Stadtbahn filled both the roles of a classic tramway system as well as an S-Bahn. The Karlsruhe mixed-operation concept
3589-530: The medians of roads . If run in streets , trains are usually limited by city block lengths to about four 180-passenger vehicles (720 passengers). Operating on two-minute headways using traffic signal progression, a well-designed two-track system can handle up to 30 trains per hour per track, achieving peak rates of over 20,000 passengers per hour in each direction. More advanced systems with separate rights-of-way using moving block signaling can exceed 25,000 passengers per hour per track. Most light rail systems in
3686-406: The 'U' logo is used at stops on services that are essentially 'classic' tram lines, not 'second-level' at all. The concept of Regionalstadtbahnen (also known by RegioStadtbahn or other names) arose as a result of the harmonisation or integration of railway lines into Stadtbahn networks. In the area of Cologne–Bonn a single operational system (of so-called above ground lines or Hochflurstrecken )

In French-speaking regions (particularly Wallonia and the bilingual Brussels Capital Region ), these concepts were labelled " pre-metro ", stressing their – then-planned and advertised – interim nature. All German cities that had a "true" U-Bahn network had plans to abandon their tramway network at one point or another. In
3880-421: The 1960s ' pre-metro ' meaning, both the 'U' (for U-Bahn ) and the 'Tram' logo are used on city maps (to indicate the location of stops) and on railway station signage (to indicate connections). The 'U' Logo is normally used both where stops or stations are underground and where they serve 'second-level' pre-metro type lines. In cities which prefix all their Stadtbahn line numbers with a 'U' (e.g. Stuttgart ),
3977-527: 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

4074-624: The 1970s was proven to have been a technical failure by the following decade. After World War II, the Germans retained many of their streetcar networks and evolved them into model light rail systems ( Stadtbahnen ). With the exception of Hamburg , all large and most medium-sized German cities maintain light rail networks. The concept of a "limited tramway" was proposed by American transport planner H. Dean Quinby in 1962. Quinby distinguished this new concept in rail transportation from historic streetcar or tram systems as: The term light rail transit
4171-495: The French city of Bordeaux , the tramway network is powered by a third rail in the city center, where the tracks are not always segregated from pedestrians and cars. The third rail (actually two closely spaced rails) is placed in the middle of the track and divided into eight-metre sections, each of which is powered only while it is completely covered by a tram. This minimizes the risk of a person or animal coming into contact with
4268-474: The North. Some operators and cities decided to identify the term Stadtbahn with the eventual goal of installing an U-Bahn so that both the original U-Bahn logo (e.g. Frankfurt U-Bahn , Cologne Stadtbahn , Hanover Stadtbahn ) and the derived U-Stadtbahn logos (e.g. North Rhine-Westphalia , Stuttgart Stadtbahn ; see example above) mark station entries and stops. The numbering scheme for Stadtbahn services
4365-489: The Stadtbahn also operates on EBO on parts of the route where track is shared with mainline rail . All four German subway systems are regulated entirely by BOStrab while parts of some tram, light rail or Stadtbahn systems – most notably Karlsruhe Stadtbahn – are regulated under EBO. Meanwhile all S-Bahn systems – including those using third rail electrification like Berlin S-Bahn – are regulated entirely under EBO. While

The O-Train Trillium Line in Ottawa also has freight service at certain hours. With its mix of right-of-way types and train control technologies, LRT offers
4559-455: The US as a whole, excluding Seattle, new light rail construction costs average about $ 35 million per mile. By comparison, a freeway lane expansion typically costs $ 1.0 million to $ 8.5 million per lane mile for two directions, with an average of $ 2.3 million. However, freeways are frequently built in suburbs or rural areas, whereas light rail tends to be concentrated in urban areas, where right of way and property acquisition
4656-666: The United States and in North America . In Britain, modern light rail systems began to appear in the 1980s, starting with the Tyne and Wear Metro from 1980 and followed by the Docklands Light Railway (DLR) in London in 1987, continuing into the 1990s including the establishment of the Manchester Metrolink in 1992 and the Sheffield Supertram from 1994. Due to varying definitions, it
4753-590: The United States are limited by demand rather than capacity (by and large, most American LRT systems carry fewer than 4,000 persons per hour per direction), but Boston's and San Francisco's light rail lines carry 9,600 and 13,100 passengers per hour per track during rush hour. Elsewhere in North America, the Calgary C-Train and Monterrey Metro have higher light rail ridership than Boston or San Francisco. Systems outside North America often have much higher passenger volumes. The Manila Light Rail Transit System
4850-472: The United States, "light rail" has become a catch-all term to describe a wide variety of passenger rail systems. Light rail corridors may constitute a fully segregated corridor, a dedicated right-of-way on a street, an on-street corridor shared with other traffic, a corridor shared with other public transport, or a corridor shared with pedestrians. The most difficult distinction to draw is that between low-floor light rail and streetcar or tram systems. There

However, to achieve capacities this high, BRT station footprints need to be significantly larger than a typical LRT station. In terms of cost of operation, each bus vehicle requires a single driver, whereas

(The usual British term for an aerial tramway is cable car , which in the US usually refers to a ground-level car pulled along by subterranean cables .) The word trolley is often used as a synonym for streetcar in the United States but is usually taken to mean a cart, particularly a shopping cart, in the UK and elsewhere. Many North American transportation planners reserve streetcar for traditional vehicles that operate exclusively in mixed traffic on city streets, while they use light rail to refer to more modern vehicles operating mostly in exclusive rights of way, since they may operate both side-by-side targeted at different passenger groups. The difference between British English and American English terminology arose in

In the case of Berlin, the network in West Berlin was shut down in 1967 while the plans to shut down the system in East Berlin were reversed and ultimately the tram network started expanding again in the last years of East Germany; it now serves some portions of the former West again.

5432-755: The direct translation, which is city rail (the Norwegian term, by bane , means the same). However, UMTA finally adopted the term light rail instead. Light in this context is used in the sense of "intended for light loads and fast movement", rather than referring to physical weight. The infrastructure investment is also usually lighter than would be found for a heavy rail system. The American Public Transportation Association (APTA), in its Glossary of Transit Terminology, defines light rail as: ...a mode of transit service (also called streetcar, tramway, or trolley) operating passenger rail cars singly (or in short, usually two-car or three-car, trains) on fixed rails in

By the 1980s conventional tramways had been seen by decision-makers as overloaded systems for more than two decades. However, public attention focused on them at this time for two reasons.

However, the requirement for saying that a rail line is "separated" can be quite low—sometimes just with concrete "buttons" to discourage automobile drivers from getting onto the tracks.

Reference speed from major light rail systems, including station stop time, is shown below. However, low top speed is not always a differentiating characteristic between light rail and other systems. For example, the Siemens S70 LRVs used in the Houston METRORail and other North American LRT systems have

Light rail vehicles are typically driven electrically with power being drawn from an overhead electric line via a trolley [pole] or a pantograph ; driven by an operator onboard the vehicle; and may have either high platform loading or low-level boarding using steps." However, some diesel-powered transit is designated light rail, such as

By contrast, light rail vehicles can travel in multi-car trains carrying a theoretical ridership up to 20,000 passengers per hour in much narrower rights-of-way , not much more than two car lanes wide for a double track system. They can often be run through existing city streets and parks , or placed in

And because the capacity of a light rail system is higher than that of

A further difference arose because, while Britain abandoned all of its trams after World War II except in Blackpool , eight major North American cities ( Toronto , Boston , Philadelphia , San Francisco , Pittsburgh , Newark , Cleveland , and New Orleans ) continued to operate large streetcar systems. When these cities upgraded to new technology, they called it light rail to differentiate it from their existing streetcars since some continued to operate both
7081-468: The same time, the smaller cities which had not started Stadtbahn plans reassessed their options in relation to their existing tram systems. Furthermore, relocating public transit or even pedestrians underground increasingly got a negative reputation and the concept of the automotive city – all but dominating public discourse in the 1950s and 1960s – was increasingly called into question. East German cities had no 1960s-style Stadtbahn plans in place, and
7178-404: The scheme. As far as the Stadtbahn terminology problem is concerned, however, the scheme serves only to add further confusion to the matter, since there is no nationwide logo for Stadtbahn services. The result appears to be a contraction in the use of the term Stadtbahn , especially in cities where it has been used in its wider 1980s 'light-rail system' meaning. In cities where Stadtbahn has
7275-556: The so-called 'second level' concept for future light rail schemes. This concept focused on the grade separation, i.e., elevation and/or tunneling of tram lines. Munich and Nuremberg decided to build pure, full-scale U-Bahn (metro) systems. Berlin and Hamburg planned expansions of their existing U-Bahn networks, while most West German cities decided to upgrade their tramway networks step by step, linking new 'second level' infrastructure to existing sections. While some cities regarded this solution as an interim step that would lead to
7372-408: The standard gauge is that standard railway maintenance equipment can be used on it, rather than custom-built machinery. Using standard gauges also allows light rail vehicles to be conveniently moved around using the same tracks as freight railways. Additionally, wider gauges (e.g. standard gauge) provide more floor clearance on low-floor trams that have constricted pedestrian areas at the wheels, which
7469-406: The suburbs are called Stadtbahn. They are represented by the 'S' logo that is used for S-Bahn ( Stadtschnellbahn ) in the rest of Germany and therefore partially conflict with it, as it has acquired a second meaning in Karlsruhe. As part of the redevelopment of their main city stations , national railway company Deutsche Bahn adopted a new logo to indicate Straßenbahn (tram) connections:
7566-551: The system was a success with the public, gaining up to 190,000 passengers per day. Automatic train operation is employed on light rail networks, tracking the position and speed of a train and hence adjusting its movement for safety and efficiency. One line of light rail (requires 7.6 m, 25' right of way) has a theoretical capacity of up to 8 times more than one 3.7 m (12 foot) lane on a freeway, excluding busses, during peak times. Roads have ultimate capacity limits that can be determined by traffic engineering , and usually experience
7663-467: The tendering process will be initiated once the project is reviewed and approved by PMO and Union Cabinet. As of 4th July 2023, the Jammu and Kashmir administration has proposed the introduction of MetroLite lines in Srinagar and Jammu cities, as reported by The Indian Express . This development aims to improve the public transportation system in the region and will be the first metro lines to be established in Jammu and Kashmir. The proposed project includes
7760-475: The train, driver's cabs on both ends, higher operating voltage, wider cars with comfortable seats, and so on. In 1992 Karlsruhe started an innovative new service, using both heavy and light rail infrastructure, to link the wider region to the city. The vehicles were designed to comply with technical specifications for the (federal) heavy railway and for light rail (communal tramways). Such vehicles are called Dual-System Light Rail Vehicles. The meaning of Stadtbahn
7857-591: The tram network, though the Stadtbahn portions do not operate with street running as much as trams do. They also differ in legal status: S-Bahn systems are governed under the rail rules of the Eisenbahn-Bau- und Betriebsordnung (EBO) ('Ordinance on the Construction and Operation of Railways'), while Stadtbahn systems are usually tramways by law governed under the regulations of Verordnung über den Bau und Betrieb der Straßenbahnen (BOStrab) ('Ordinance on
7954-503: The trams, making it safe on city streets. Several systems in Europe and a few recently opened systems in North America use diesel -powered trains. When electric streetcars were introduced in the late 19th century, conduit current collection was one of the first ways of supplying power, but it proved to be much more expensive, complicated, and trouble-prone than overhead wires . When electric street railways became ubiquitous, conduit power
8051-460: The vast majority of light rail systems. This avoids the danger potentially presented by an electrified third rail . The Docklands Light Railway uses an inverted third rail for its electrical power, which allows the electrified rail to be covered and the power drawn from the underside. Trams in Bordeaux , France, use a special third-rail configuration where the power is only switched on beneath
8148-434: The widest range of latitude of any rail system in the design, engineering, and operating practices. The challenge in designing light rail systems is to realize the potential of LRT to provide fast, comfortable service while avoiding the tendency to overdesign that results in excessive capital costs beyond what is necessary to meet the public's needs. The BART railcar in the following chart is not generally considered to be
8245-587: The word "Tram" at the expense of Straßenbahn and elektrische ("electric [railway/tramway]") the latter of which having become somewhat antiquated. The term "Bim" (short for "Bimmelbahn" in turn derived from the semi- onomatopoetic "bimmeln" for the sound of a bell) meanwhile has become limited to Austria, particularly the "Bim" in Vienna . As the new logos became part of the information systems at more and more main railway stations, an increasing number of cities and public transport operators came to accept and adopt
8342-491: The year 2027. The Line 2 is planned to be extended until Srinagar Airport in phase 2. The depot is set to be constructed near HMT Junction of Line 1. (HMT Junction - Indira Nagar) Connection (Osmanabad - Hazoori Bagh) Light rail transit 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 while also having some features from heavy rapid transit . The term
8439-765: Was also adopted by the Saarbahn in Saarbrücken . This model is today referred to in France as the tram-train . Other Stadtbahn networks in Germany without tunnels, but which incorporate railway lines, are found in: Although a precise legal definition of Stadtbahn was planned in the 1970s, there is currently no such definition. By law, the BOStrab regulates all Stadtbahn systems as tram systems, as long as they are not mainline rail. However, all U-Bahn systems in Germany are likewise regulated by BOStrab. In some systems,
8536-543: Was coined in 1972 by the U.S. Urban Mass Transportation Administration (UMTA; the precursor to the Federal Transit Administration ) to describe new streetcar transformations that were taking place in Europe and the United States. In Germany, the term Stadtbahn (to be distinguished from S-Bahn , which stands for Stadtschnellbahn ) was used to describe the concept, and many in UMTA wanted to adopt
8633-502: Was coined in 1972 in the United States as an English equivalent for the German word Stadtbahn , meaning "city railway". Different definitions exist in some countries, but in the United States, light rail operates primarily along exclusive 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
8730-685: Was created by the Cologne Stadtbahn and the Bonn Stadtbahn , opened in 1974, from the conversion of two former railway lines (the Rheinuferbahn and Vorgebirgsbahn belonging to the old Köln-Bonner Eisenbahnen ). Further developments led to tram-train networks that rather resembled an S-Bahn . This idea was first realised in 1992 in Karlsruhe ( Karlsruhe Stadtbahn ), where as part of the Karlsruhe model even so-called dual system railbuses were used, which in addition to
8827-543: Was enlarged to encompass this new type of " tram-train " service. In other regions, stimulated by the Karlsruhe example and planning to copy it, other terms are in use: Stadt-Umland-Bahn (city-to-region railway, e.g. Erlangen , also in discussion to connect the nearer surroundings of Munich , as far as not supplied with S-Bahn services so far, with the existing public transport there), Regional-Stadtbahn (regional light rail, e.g. Braunschweig ). The difference of this system to other systems where light rail mixes with heavy rail,
8924-453: Was in the beginning a system of heavy rail lines circling the city, free of level crossings, operated by steam trains. After World War I the Wiental , Donaukanal and Gürtel lines were converted into an electric light rail system with tram-like two-axle cars (which on line 18G until 1945 switched into the tram network at Gumpendorfer Strasse station). In the 1970s to 1990s the infrastructure
9021-677: Was introduced in North America in 1972 to describe this new concept of rail transportation. Prior to that time the abbreviation "LRT" was used for " Light Rapid Transit " and " Light Rail Rapid Transit ". The first of the new light rail systems in North America began operation in 1978 when the Canadian city of Edmonton, Alberta , adopted the German Siemens-Duewag U2 system, followed three years later by Calgary, Alberta , and San Diego, California . The concept proved popular, with there now being numerous light rail systems in
9118-509: Was prefixed with a 'U', except in the Cologne Stadtbahn , Bielefeld Stadtbahn , and Hanover Stadtbahn . In local parlance some of those systems are referred to as "U-Bahn", especially when talking about tunnel sections. However, this somewhat misleading terminology is only officially used in Frankfurt am Main which calls its Stadtbahn "Frankfurt U-Bahn". Official documents and specialist publications or railfans and transit advocates maintain
9215-632: Was the Gross-Lichterfelde tramway in Lichterfelde near Berlin in Germany, which opened in 1881. It was built by Werner von Siemens who contacted Pirotsky. It initially drew current from the rails, with overhead wire being installed in 1883. The first interurban to emerge in the United States was the Newark and Granville Street Railway in Ohio, which opened in 1889. An early example of
9312-528: Was updated, and the lines were partially relocated: they are now part of the Vienna U-Bahn services 'U4' and 'U6'. The Vorortelinie line remained heavy rail and is now part of the Vienna S-Bahn . Since the 1960s the term Stadtbahn has become identified with a second, now dominant, meaning. Here Stadtbahn is an underground urban rail network that is used by conventional trams but planned at
9409-527: Was used in those cities that did not permit overhead wires. In Europe, it was used in London, Paris, Berlin, Marseille, Budapest, and Prague. In the United States, it was used in parts of New York City and Washington, D.C. Third rail technology was investigated for use on the Gold Coast of Australia for the G:link light rail, though power from overhead lines was ultimately utilized for that system. In
