The line is named after Judah Street that it runs along for much of its length, named after railroad engineer Theodore Judah . It links downtown San Francisco to the Cole Valley and Sunset neighborhoods. The line provides rail access to Golden Gate Park . It is the busiest line in
180-724: 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

From the western end of the tunnel, the route goes along Carl Street, past UCSF-Parnassus Campus , on Irving Street, until it turns onto 9th Avenue for one block and reaches Judah Street, which the N runs on for the rest of its route. On Judah between 9th Avenue and 19th Avenue

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

Construction of the Market Street entrances was to begin in 2020, with completion in 2027. The entrances on the southern side of the station were closed from April 13, 2020, to May 15, 2021, due to low ridership during
630-403: 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
720-1102: 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

The sculpture was removed in June 2014 and returned to Shawcroft – a professor emerita at UC Davis School of Design – who planned to repurpose it into other pieces. Embarcadero station is located in the busy Financial District; numerous routes by several transit providers stop at or near
900-607: A large fare mezzanine level, with separate platform levels for Muni Metro and BART below. Embarcadero station opened in May 1976 – almost two years after service began through the Transbay Tube – as an infill station . Embarcadero and nearby Montgomery Street stations are typically the two busiest in the BART system. The station is served by the BART Blue , Green , Red and Yellow lines, and
990-416: 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

#17328515292071080-435: 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,
1170-481: 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
1260-570: 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 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
1350-631: 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
1440-407: 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
1530-530: 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
1620-474: 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
1710-513: Is a fare mezzanine, with one Muni paid area in the middle flanked by two BART paid areas. The second level has a single island platform (of which only the center portion is used) for Muni Metro, and the third level has an island platform for BART. The station is narrower than the other three – 50 feet (15 m) rather than 60 feet (18 m) – because of adjacent buildings and the high water table . It has six street entrances along its length. The station contains an unused underground entrance to
1800-561: 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 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
1890-462: 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
SECTION 20
#17328515292071980-565: 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
2070-602: 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
2160-560: 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
2250-426: 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
2340-498: 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
2430-575: 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
2520-549: 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
2610-480: 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

As a result of increasing development in the lower Market Street area, the basic structure of the station was added into the construction of

Light-rail service was re-replaced with buses on August 25 due to issues with malfunctioning overhead wire splices and
3060-535: 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
3150-735: 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
3240-624: 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
3420-673: 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

From the Caltrain depot at Fourth and King Streets, it runs along King Street and the Embarcadero , passing by Oracle Park . It then enters the Market Street subway , which it shares with the five other Muni Metro lines. It exits the tunnel at Church Street and, after
3600-530: 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
3690-619: 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

It was one of San Francisco's streetcar lines, beginning operation in 1928, and was partially converted to modern light-rail operation with the opening of the Muni Metro system in 1980. While many streetcar lines were converted to bus lines after World War II , the N Judah remained a streetcar line due to its use of

After concerns from riders of constant overcrowding of the trains on the N Judah line, Muni debuted an express bus route called the NX Judah Express on June 13, 2011. Starting off as a pilot program, the NX (stylized as N ) was intended to relieve overcrowding during rush hours every ten minutes. It follows
4320-457: The N runs on a right-of-way that is slightly raised above the surrounding street. There is a loop in the intersection at Judah, La Playa and Great Highway that the N uses to turn around. As with all Muni lines, service begins around 5 a.m. on weekdays, 6 a.m. on Saturdays, and 8 a.m. on Sundays and holidays. Daytime headways are 10 minutes on weekdays and 12 minutes on weekends. The line largely uses two-car (150-foot (46 m)) trains. Service

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
4770-583: 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
4860-472: 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

(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

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

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
6480-458: The shuttles had increased capacity on the inner part of the line by 18% and reduced the number of passengers unable to board overcrowded trains by 63%. In March 2018, the SFMTA board voted to shorten rush-hour headways from 7 minutes to 4 minutes, but to only use one-car trains on weekends. The changes were to take effect in the summer. On March 30, 2020, Muni Metro service was replaced with buses due to
6570-408: 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
6660-490: The station is adjacent to the Transbay Tube, brake dust and other particles from train operations coat the walls of the station. A sandblasting in 2014 revealed the original white terrazzo platform walls under the dark grime. Since before 1992, the station was serenaded by Ronald Brewington, known as the "Jazz Man". He would play saxophone for commuters, and entertain them with conversation and charm. He claimed his name
6750-535: The station. Most radial Muni bus routes terminate at several nearby locations: Other Muni routes that stop or terminate near the station include routes 1 , 9R , 14R , 14X , 30X , 41 , 81X , 82X , 714 , J Bus , K Bus , K Owl , L Bus , L Owl , M Bus , N Owl , and N Bus . The California Street line of the San Francisco cable car system terminates adjacent to the Drumm Street station entrance. Muni's F Market and Wharves heritage streetcar line stops on
6840-399: The surface at Market and Main (westbound) and Market and Drumm (eastbound). A number of Golden Gate Transit bus routes stop near Embarcadero on Fremont Street (2, 4, 38, 44, 54, 56, 58, 72, 72X, 74, 76) and/or Pine Street (2, 4, 8, 18, 24, 24X). Other transit agencies that stop nearby include SamTrans (292, 397, 398, 713, FCX) and PresidiGo (Downtown Shuttle). Embarcadero station
6930-471: The surface section on the Embarcadero was served only by the T Third Street line, plus the J Church line at peak hours. The changes were unpopular with the public; they caused severe delays in the Market Street subway and forced N Judah riders to transfer to reach the Caltrain station when they previously did not. On June 30, 2007, Muni reversed several of the changes; the J Church and N Judah were restored to their previous configuration. On December 5, 2009,
7020-551: 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
7110-499: 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
7200-455: 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
7290-463: The western end of the N Judah route from Ocean Beach to 19th Avenue, then operates nonstop from there to the Financial District where it stops at Bush and Montgomery Streets. In September 2016, Muni began running a pair of one-car shuttles between Embarcadero station and Carl and Hillway during morning rush hour to reduce crowding on the inner section of the line. A study after one month showed
7380-434: 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
7470-400: Was Garrick Sherrod; however, that was an identity he had stolen . The Jazz Man was actually a fugitive from Albuquerque facing capital murder charges stemming from the 1987 death of his wife Diedre. He was arrested at a BART station in 2012, and extradited to New Mexico . In 2013, he pleaded guilty to the murder and was sentenced to 16 years in prison. Following the 2015 addition of
7560-527: 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
7650-469: Was installed at the northwest end of the station in 1976 or 1978. Created by Barbara Shawcroft, the orange-and-white Nomex sculpture moved with the breeze from passing Muni and BART trains. Legs soon accumulated the same dark grime as the station walls, hiding the original color. BART was required by the artist's contract to clean the sculpture but several attempts were unsuccessful. In 2013, BART included removal of Legs in its 2014 budget, which prompted
7740-662: 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
7830-492: Was originally intended to be the inbound terminus for all of the Muni Metro lines. In 1998 a new southward extension was opened, extending the N Judah along the Embarcadero to the Caltrain station at 4th and King Streets . On March 4, 2000, F Market & Wharves streetcar service was extended northward to Fisherman's Wharf , with new stops above Embarcadero station at Main Street (inbound) and Drumm Street (outbound). Because
7920-422: Was originally served by a temporary shuttle service, the E Embarcadero, which ran between Embarcadero station and 4th and King/Caltrain. On August 22, 1998, the E Embarcadero line was eliminated and the N Judah line was extended in its place. A variety of service changes took place with the introduction of full service on the T Third Street line on April 7, 2007. The N Judah was cut back to Embarcadero station;
8010-610: 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
8100-517: 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
