The '''T Third Street''' is a [[Muni Metro]] line in [[San Francisco, California]]. It is the first new light rail line in San Francisco in more than half a century and the first fully [[Accessibility|accessible]] line in the system.

== Route description ==
[[File:Muni Metro destination sign changed from K to T.webm|thumb|left|The [[destination sign]] of an inbound Muni Metro K train changed from ''K Ingleside'' to ''T Third Street'' at [[West Portal Station]].]]
Testing on the line took place in summer 2006,<ref>{{Cite news |last=Gordon |first=Rachel |date=July 26, 2006 |title=Third Street seeing streetcars / Test runs for light-rail project begin at last |work=[[San Francisco Chronicle]] |url=http://www.sfgate.com/bayarea/article/SAN-FRANCISCO-T-Third-line-causing-delays-so-2589267.php |access-date=2013-12-15}}</ref> with limited service starting on January 13, 2007, and full service beginning on April 7, 2007.<ref>{{Cite news |last=Cabanatuan |first=Michael |date=January 12, 2007 |title=T-Third Muni line starts service Saturday |work=[[San Francisco Chronicle]] |url=http://www.sfgate.com/default/article/T-Third-Muni-line-starts-service-Saturday-2623955.php |access-date=2013-12-15}}</ref> It runs along the [[Third Street Light Rail Project|newly constructed light-rail tracks]] on Third Street and Bayshore Boulevard in the [[Visitacion Valley, San Francisco, California|Visitacion Valley]], [[Hunters Point, San Francisco, California|Bayview/Hunters Point]], [[Dogpatch, San Francisco, California|Dogpatch]], and [[Mission Bay, San Francisco, California|Mission Bay]] neighborhoods, connecting to the existing Muni Metro system along the [[Embarcadero, San Francisco, California|Embarcadero]] and under [[Market Street, San Francisco, California|Market Street]].

In the future, the line may be going to [[Caltrain]]'s [[Bayshore (Caltrain station)|Bayshore Station]] (to which it was originally planned to run) and, in the other direction, to San Francisco's [[Washington Square (San Francisco)|Washington Square]] in [[North Beach, San Francisco|North Beach]] through Chinatown [[Central Subway]] route.

===Operation===
{{expand section|date=February 2022}}
The T Third operates seven days a week, beginning at 5 a.m. on weekdays, and 6 a.m. Saturdays and 8 a.m. Sundays, operating until 1 a.m.

==History==
Following service changes on June 30, 2007, the [[K Ingleside]] and the T Third Street lines were combined inside the Market Street subway tunnel.<ref>{{cite news|last=Gordon|first=Rachel|date=June 4, 2007|title=T-Third line causing delays, so officials consider new routes|newspaper=[[San Francisco Chronicle]]|url=http://www.sfgate.com/bayarea/article/SAN-FRANCISCO-T-Third-line-causing-delays-so-2589267.php|access-date=2013-12-15}}</ref> Though keeping their line designations, resulting in an upside-down, [[horseshoe]]-shaped route from Balboa Park to Bayshore and Sunnydale. At [[West Portal Station]], inbound K trains heading towards downtown change their signs to the T line; at [[Embarcadero Station]], T trains heading into downtown change signs to the K line.

The underground section of the line was closed west of [[Castro station]] from June 25 to August 24, 2018, due to the [[Twin Peaks Tunnel#Rail replacement project|Twin Peaks Tunnel shutdown]].<ref name="tpt">{{Cite web |date=June 25, 2018 |title=Twin Peaks Tunnel Improvements |url=https://www.sfmta.com/projects/twin-peaks-tunnel-improvements-0 |archive-url=https://web.archive.org/web/20180626232234/https://www.sfmta.com/projects/twin-peaks-tunnel-improvements-0 |archive-date=June 26, 2018 |publisher=San Francisco Municipal Transportation Agency}}</ref> On August 25, 2018, at the end of the shutdown, Muni began running two-car trains on the K/T line.<ref>{{Cite press release |title=Two-Car Trains Now Permanent on K/T Line |date=August 24, 2018 |publisher=San Francisco Municipal Transportation Agency |url=https://www.sfmta.com/blog/two-car-trains-now-permanent-kt-line |last1=von Krogh |first1=Bonnie Jean}}</ref>
