Single Tracking Alert: Service reduced to only one track in the Transbay Tube on three Sundays for critical lighting work (next workday Sunday, June 7)

BART crews will be in the Transbay Tube to replace lights in the tube on three upcoming Sundays. The work will take place on June 7, and July 19.

The work will be for the entire day on all three Sundays, which will reduce our normal service from two tracks to one. Service impacts on both days will include:

• Trains will run every 30 minutes systemwide
• Only 3 lines will be in service (Blue, Yellow, Orange)
• Red and Green Line service will not operate
• A Yellow Line shuttle train will run between SFO and Millbrae all day - Passengers traveling beyond SFO must transfer

BART's Trip Planner will be updated to reflect schedule changes for these days. Riders are strongly encouraged to plan their trips in advance.
