Possible delays and missed transfers after 9 pm from single tracking through the Transbay Tube

BART is in the middle of a multi-year project to retrofit the Transbay Tube.  The retrofit will be done in small sections during a work window of 9:30 pm (Sunday-Thursday) until 5:00 am (Monday-Friday).

Passenger trains will need to single track through the tube during this work, resulting in 24-minute headways after 9 pm on weeknights (extra trains will be provided on Friday nights). 

While this work has been built into the schedule, it is possible the single tracking and movement of work equipment and maintenance vehicles may cause delays of 10-15 minutes, in addition to the 24 minute headways, which is how frequently a train arrives.

This work has also been impacting our ability to make timed transfers at 19th Street Station.  Riders transferring after 10 pm at 19th Street should allow for extra time in case the timed-transfer can not be made. Bus transfers may also be impacted due to the work.

Some trips will not be impacted.
