N Judah
Template:Short description Template:Use American English Template:Use mdy dates Template:Infobox rail line
The N Judah is a hybrid light rail/streetcar line of the Muni Metro system in San Francisco, California. The line is named after Judah Street that it runs along for much of its length, named after railroad engineer Theodore Judah.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It links downtown San Francisco to the Cole Valley and Sunset neighborhoods. The line provides rail access to Golden Gate Park.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It is the busiest line in the Muni Metro system, serving an average of 41,439 weekday passengers in 2013.<ref name="ridership">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It was one of San Francisco's streetcar lines, beginning operation in 1928,<ref name=nimmo>Template:Cite book</ref> 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 the Sunset Tunnel.
Route descriptionEdit
The line runs from the Caltrain depot in the Mission Bay district to Ocean Beach and the Great Highway in the Sunset District. 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 a brief stretch along Duboce Avenue to Duboce Park, enters the older Sunset Tunnel. This tunnel serves to avoid a hill and contains no underground stations. 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 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.
OperationEdit
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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The line largely uses two-car (Template:Convert) trains.
Service is provided by overnight Owl buses on the N Owl route during the hours that rail service is not running. On weekends, the N Judah Bus service runs from 5 am until the start of rail service. The bus lines largely follow the rail line, but use surface streets to parallel sections where the rail line has dedicated rights-of-way.<ref>Template:Cite press release</ref>
HistoryEdit
On January 10, 1998, Muni opened the Muni Metro Extension to 4th and King/Caltrain. It was originally served by a temporary shuttle service, the E Embarcadero, which ran between Embarcadero station and 4th and King/Caltrain.<ref name=extends>Template:Cite news</ref><ref name=cbtc>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> On August 22, 1998, the E Embarcadero line was eliminated and the N Judah line was extended in its place.<ref name=extends /><ref>Template:Cite news</ref>
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; the surface section on the Embarcadero was served only by the T Third Street line, plus the J Church line at peak hours.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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.<ref>Template:Cite press release</ref> On December 5, 2009, the N Judah was cut to Embarcadero on weekends as part of widespread service reductions.<ref>Template:Cite press release</ref> Weekend service was re-extended on October 15, 2011.<ref>Template:Cite press release</ref>
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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Starting off as a pilot program, the NX (stylized as Nx) was intended to relieve overcrowding during rush hours every ten minutes. It follows 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.<ref>Template:Cite press release</ref> A study after one month showed 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%.<ref>Template:Cite press release</ref> 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.<ref>Template:Cite news</ref>
COVID-19Edit
On March 30, 2020, Muni Metro service was replaced with buses due to the COVID-19 pandemic.<ref>Template:Cite press release</ref>
Light-rail service returned in August 2020, with the routes reconfigured to improve reliability in the subway. N Judah service was not substantially changed, except for stops at 5th Avenue / 6th Avenue replacing former stops at 4th Avenue and 7th Avenue.<ref name="aug22">Template:Cite press release</ref><ref>Template:Cite press release</ref> Light-rail service was re-replaced with buses on August 25 due to issues with malfunctioning overhead wire splices and the need to quarantine control center staff after a COVID-19 case.<ref>Template:Cite press release</ref>
N Judah light-rail service resumed on May 15, 2021.<ref>Template:Cite press release</ref>
FutureEdit
Plans, according to the SFMTA Rail Capacity Strategy, include a new subway tunnel that connects the Market Street subway to 9th Avenue. Additionally, the N Judah line will be rebuilt to run three-car trains. Further plans include a non-revenue L Taraval to N Judah connector, which may run on 46th Avenue.<ref name="Draft study">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
