The agency’s Planned Service Advisories, updated June 2, 2026, state that crews will perform rail destressing, a process of adjusting rail tension to prevent buckling, which requires reducing service from two tracks to one. ## Service Impact Maintenance occurs between midnight and the start of service the following morning. During these windows, passengers should expect 20-25 minute delays. The agency lists 40 specific dates for this work. The service reduction affects the Contra Costa County segment of the Yellow Line. While the agency has not specified every station segment for all 40 dates, the advisory confirms work between North Concord and Pittsburg/Bay Point stations is set for June 10-12, 2026. ## Maintenance Schedule Work is scheduled for June 10-12, June 15, and June 24.

The agency’s public advisories do not state whether these late-night maintenance delays will be suspended during tournament match days. The records do not specify if alternative bus bridges will be offered to passengers during the 20-25 minute delay windows. BART notes that the maintenance schedule is subject to updates. ## Key Questions **How long will these delays last?** Maintenance work will cause 20-25 minute delays on scheduled work nights between midnight and the start of morning service, continuing through December 21, 2026. **Which stations are affected?** The work is concentrated on the Yellow Line in Contra Costa County, with specific maintenance between North Concord and Pittsburg/Bay Point stations confirmed for June 10-12.
