Today’s commute turned into a grind for BART riders after an equipment problem on the track near San Bruno knocked out service between SFO and San Bruno, triggering a major disruption along the busy airport corridor. Trains headed toward Antioch, Richmond, SFO and Millbrae were all caught up in the mess, leaving riders scrambling as crews rushed to the scene to work on restoring service.
BART alert and affected service
According to BART Alert, the agency reported “no train service” on the SFO–San Bruno segment and described the issue as equipment on the track. The message labeled it a major delay and listed trips toward Antioch, Richmond, SFO, and Millbrae as impacted. BART told riders to expect extended travel times while crews troubleshoot the problem.

Practical impacts and rider guidance
BART’s service-advisories page and official app are the agency’s main tools for real-time updates and route guidance, and the system typically posts station-level information, cancellations and alternatives there, according to BART. Riders can sign up for email or text alerts and check real-time departures on the official site to see how the outage hits their particular trip. For Peninsula travel, alternatives such as Caltrain and SamTrans may offer detours while BART works to bring the line back up.
Recurring delays and ongoing upgrades on the corridor
The SFO/Millbrae corridor has endured similar equipment-related outages near San Bruno in past years, with local coverage documenting single-tracking and suspended service during earlier incidents, as reported by SFGATE. Transit reporting also notes that BART is carrying out train-control modernization on the airport segment, a project that has prompted planned late-night slowdowns while crews install new systems, according to Moovit. Taken together, those planned upgrades and occasional unscheduled equipment faults have made this stretch one of the system’s more disruption-prone corridors.
Monitor official updates
BART had not provided an estimated time for full restoration when it posted its advisory, and riders are urged to keep an eye on BART Alert and the agency’s alerts page for the latest information. We will update this post if BART confirms restored service or issues specific routing instructions for affected riders.
