BART schedules Yellow Line track maintenance through December 21, 2026 | The Locally Times
Rail destressing work on 30 nights through December 21, 2026, will force single-track operations and 20-25 minute delays.
BART will reduce Yellow Line service to a single track on 30 nights through December 21, 2026, to perform rail destressing in Contra Costa County. The agency's June 11, 2026, Planned Service Advisories indicate that maintenance begins at midnight on each scheduled date and continues until regular service resumes the following morning. ## Service Delays Riders traveling during these maintenance windows face delays of 20-25 minutes. The agency identified 30 specific dates for this project, including June 24 and various nights from July through December. ## Additional Maintenance BART reports 30-minute delays for passengers traveling between Millbrae, SFO, and Daly City stations due to train control modernization. These delays occur Sunday through Thursday, starting at 9 p.m. Additionally, crews scheduled rail replacement work between the Downtown Berkeley and MacArthur stations for Saturday, June 20, 2026. This project reduces service to a single track starting at 10:30 p.m., causing anticipated delays of 20-30 minutes for East Bay travelers. ## Resident Impact A rider catching a train after midnight on a scheduled Yellow Line work night will experience a 20-25 minute increase in travel time compared to standard operations. Those traveling through the SFO/Millbrae corridor after 9 p.m. on weeknights face a 30-minute delay. While BART provides special late-night service for FIFA World Cup matches on June 19 and 22, 2026, these exceptions do not apply to the broader maintenance schedule. ## Key Questions **How much extra time should I allow for late-night travel?** Yellow Line riders during maintenance nights should add 20-25 minutes to their trip, while those traveling between Millbrae, SFO, and Daly City after 9 p.m. on weeknights should expect 30-minute delays. **How long will these Yellow Line disruptions continue?** The rail destressing project on the Yellow Line is scheduled to continue through December 21, 2026, with maintenance occurring on 30 specific dates throughout the year.
