Single Tracking Alert: Rail replacement work in the Transbay Tube – Sunday, October 19; no Red or Green Line service Sunday morning until 10:30am

BART crews will perform rail replacement work in the Transbay Tube over the weekend of October 18-19, requiring late night and morning single tracking and temporary service adjustments.

BART's Trip Planner has been updated to include the special schedule and help people plan their trips.

Saturday night, October 18:

Trains will single track through the Transbay Tube beginning around 12:30 am, with delays of 10-15 minutes expected. 

Sunday morning, October 19:

Single tracking will continue from start of service at about 8 am to 10:30 am. During this time, BART will operate a three-line, 30-minute schedule to all stations to mitigate delays. There will be no Red or Green Line service until 10:30 am which means some riders will need to take an Orange line train and transfer to complete their trip. Normal 20-minute, 5-line service will resume at 10:30 am on Sunday.
