Red, Green and Blue line services severely impacted as power problem between two downtown stations disrupts morning commute
Bay Area commuters faced significant disruptions Monday morning after a power problem between two downtown San Francisco stations brought normal service to a halt on one of the transit system’s busiest segments. The outage affected multiple train lines and forced thousands of riders to seek alternative routes during the morning rush.
BART officials reported at 7:20 a.m. that a power issue between Powell Street and Embarcadero stations was causing widespread service disruptions on the San Francisco Line in all directions. The problem forced the transit agency to severely restrict transbay travel, limiting cross-bay service primarily to Yellow Line trains.
Multiple lines suspended or curtailed
The power failure had cascading effects across the BART network. 1) Red Line train service was completely suspended, leaving riders without access to that route entirely. 2) Blue Line trains were restricted to operating only between Dublin/Pleasanton and West Oakland stations, eliminating through service to San Francisco. 3) Green Line trains between Berryessa and Daly City stations were also halted, cutting off another major route for commuters.
The disruption created complicated transfer scenarios for passengers attempting to reach their destinations. Commuters traveling from the San Francisco line received instructions to board a Dublin/Pleasanton train and transfer at Bay Fair station to a Berryessa train to complete their journeys. Passengers originating from the Berryessa line were advised to board a Richmond train and make a transfer at Bay Fair to a Daly City train.
Agency provides limited timeline information
BART officials did not immediately offer an estimate for when full service would resume across all affected lines. The transit agency advised commuters to expect significant delays while maintenance crews worked to identify and resolve the power issue causing the disruption.
The lack of a clear timeline added to commuter frustration during the morning rush period, when trains typically operate at or near capacity. Many riders were forced to adjust their morning schedules or seek alternative transportation options to reach their workplaces on time.
Pattern of recurring service problems
Monday’s power failure represents the latest incident in a series of disruptions that have plagued the transit system for months. The frequency of service interruptions has raised concerns among regular commuters who depend on reliable BART service for their daily transportation needs.
On November 24, an equipment problem in the East Bay resulted in the shutdown of both the Red and Green lines. Just days earlier on November 21, vandalism was suspected as the cause of another disruption, though BART officials stated that incident was not connected to other problems experienced throughout the year.
October and earlier incidents compound reliability concerns
The transit system experienced additional troubles on October 20 and October 27, when issues affected the Transbay Tube, a critical underwater section connecting San Francisco with the East Bay. These disruptions particularly impact commuters who rely on transbay service, as alternative routes are limited.
On September 5, a computer-related issue caused systemwide delays affecting all BART lines simultaneously. The technological failure highlighted the system’s vulnerability to digital infrastructure problems that can cascade across the entire network.
There is currently no Red Line service. For Millbrae take the shuttle train between SFO and Millbrae and transfer to/from the Yellow line (Antioch-SFO). Millbrae riders from Richmond take the Orange/Berryessa train and transfer at MacArthur to the Yellow/SFO train.

Summer incidents raised safety questions
More serious safety concerns emerged on August 29 when riders were left stranded after train brakes overheated and smoke filled the Transbay Tube. The incident raised questions about equipment maintenance and safety protocols for one of the system’s most critical and challenging sections.
Perhaps the most disruptive incident occurred on May 20, when a fire on the tracks forced the complete shutdown of Green Line service for multiple days. The extended outage required thousands of commuters to find alternative transportation arrangements while repairs were completed.
Commuters seek reliability improvements
The recurring nature of these disruptions has intensified calls for infrastructure improvements and more robust maintenance procedures. Many riders have expressed frustration with the unpredictability of service, which complicates daily planning and can result in missed meetings or appointments.
Transit advocates note that reliable service is essential for encouraging commuters to choose public transportation over private vehicles, particularly as the Bay Area continues to address traffic congestion and environmental concerns. Each service disruption potentially drives some riders back to driving, undermining broader regional transportation and sustainability goals.
BART officials continue to work on addressing both the immediate power issue and the longer-term reliability challenges facing the aging transit system.
