A fire reported near Union City Station brought BART trains to a standstill between Fremont and South Hayward yesterday, according to the transit agency. Riders along the affected corridor ran into suspended service and replacement buses while crews headed to the scene. As of early Thursday, officials were sharing few details while emergency responders secured the area and inspectors checked trackside equipment.

Rider impact and alternatives
AC Transit's Line 200 runs between Union City and Fremont and is commonly used as an alternate when trains are down, so riders should expect that route and local Bus 9 to carry many displaced commuters. Allow extra time for trips, expect crowding on buses, and have fare media or a Clipper card ready when transferring.
Fire disruption is a recurring risk
Fires near BART trackways have forced service suspensions before and sometimes damaged fiber or power equipment, extending outages. The San Francisco Chronicle reported a February blaze that shuttered South Hayward for much of a day, and Hoodline covered a Warm Springs brush fire that snarled service earlier this month.
Where to get updates
BART posts real-time advisories on its Alerts and Advisories page and on its X feed, so check BART alerts for the latest on restorations. AC Transit also lists substitution options on its AC Transit BART alternatives page, and riders should plan for longer trips until BART confirms normal service is restored.
