The L Taraval is a light rail line of the Muni Metro system in San Francisco, California, mainly serving the Parkside District.

[5] This trackage, which saw irregular passenger service, formed a barrier to the continued expansion of the city-owned Municipal Railway into the Parkside district.

Tracks were extended along Taraval to 48th Avenue at Ocean Beach by January 14, 1923 and on October 15, the shuttle service was replaced with larger streetcars running through to the Ferry Building.

The L was partially converted to modern light rail operation as part of the opening of the Muni Metro system in 1980.

Because the rails were in the center of a four-lane roadway, passengers boarding or exiting must cross an active traffic lane.

Starting in the early 2010s, Muni began proposing major changes to the L Taraval corridor to increase pedestrian safety and speed up trains, which would prove controversial.

Under pressure from these groups, Muni agreed to a pilot project in 2016 to see if better street markings would get more drivers to stop for crossing passengers.

[19] Rail service was replaced again by buses on August 25, 2020 due to issues with malfunctioning overhead wire splices and the need to quarantine control center staff after a positive COVID-19 case.

[20] K Ingleside rail service resumed again on May 15, 2021, and Segment A work was completed that July, but the L remained a bus route.

[24] Additional limited bus service to downtown, operating weekday middays on 50-minute headways, was added on October 10, 2022.
