Possible delays 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.

Some trips will not be impacted.
