BART Suspends Transbay Tube, Stranding Riders After Communications Loss

Transbay Tube service between San Francisco and Oakland was suspended after Bay Area Rapid Transit detected a loss of communications that affected operations, leaving trains halted and riders stranded for more than two hours. The interruption forced the abrupt stoppage of transbay runs and disrupted evening travel across the Tube.

The agency took the action Sunday evening, Feb. 22, 2026, when the communications problem emerged, suspending all Transbay service while staff worked to secure trains and manage onboard passengers. BART’s decision removed a primary rail link between San Francisco and Oakland during a peak travel period and halted trips that normally run through the Tube.

Riders were left aboard stopped trains for more than two hours before service resumed, creating extended delays for commuters who depend on the transbay connection. The outage affected operations specifically on the Transbay Tube corridor between San Francisco and Oakland and interrupted scheduled trains that normally cross the Bay.

Four days after the suspension, on Feb. 26, 2026, the interruption remains the most recent major communications-related stoppage to affect the Tube; BART identified the immediate cause as a loss of communications that impacted operations. The agency’s suspension of Transbay service on Feb. 22 highlights vulnerabilities in the critical rail link between San Francisco and Oakland and the potential for prolonged passenger delays when communications fail.
