of the K line was through-routed with the J Church line. On August 25, 2018, at the conclusion of the shutdown, Muni began running permanently two-car trains on the K/T line (as had been used east of Castro during the shutdown). Because of insufficiently-long boarding islands, the rear car was closed on the Ocean Avenue section of the line. Passengers in the rear car on outbound trains were forced to move to the front car at Junipero Serra and Ocean station, and inbound K trains did not open the rear car to passengers until passing Junipero Serra and Ocean. On March 30, 2020, Muni Metro service was replaced with buses due to the COVID-19 pandemic. Rail service returned on August 22, 2020, with the routes reconfigured to improve reliability in the subway: K Ingleside and L Taraval service were interlined, running between Taraval and Sunset and Balboa Park station; no K Ingleside or L Taraval service entered the subway. At that time, buses replaced rail service west of Sunset Boulevard to allow for construction. The T Third Street line was interlined with the M Ocean View line instead of the K Ingleside. The forced transfer at West Portal was criticized by disability advocates. K Ingleside light-rail service was replaced again by the K Bus 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. K Ingleside light-rail service resumed again on May 15, 2021; again, through-routed with T Third Street. On January 7, 2023, the T Third Street line was rerouted into the Central Subway ending 16 years of being interlined with the K Ingleside, which will terminate at Embarcadero. Future Future proposals for the K line include an extension on Geneva Avenue from the Balboa Park station to Bayshore Boulevard, with a connection to the T Third Street line and a possible connection to the Bayshore Caltrain station in Brisbane. This has been identified as a Tier 1 level project. Additional plans include a subway with a portal entrance south of Saint Francis Circle on Junipero Serra Boulevard that connects to the existing Twin Peaks Tunnel, as part of the M Ocean View subway project. Station listing The K Ingleside line stops at concrete boarding islands in the middle of the street next to the tracks. Some stops have raised platforms for accessibility. References
