BART has adjusted service after 9 p.m. between Daly City and West Oakland so that a train comes every 15 minutes.
Previously, two trains would arrive within a few minutes of each other, followed by a 28-minute gap in service. Now, one train will arrive about every 15 minutes, reducing wait times for many riders in San Francisco.
BART made the adjustment because it no longer needs late-night single tracking for the Transbay Tube Seismic Retrofit Project, which closed half of the Tube each night and caused delays as trains waited their turn. The project often impacted timed transfers.
Also, BART has added four morning trains back to the schedule that had been canceled because of the Transbay Tube earthquake retrofit project, according to the transit agency. Those trains include the 4:40 a.m. train starting in Daly City (Yellow line); the 5:44 a.m. train starting in Antioch (Yellow); the 4:30 a.m. train starting at South Hayward (Green line); and the 5:29 p.m. train that starts at Daly City (Green).
