Weekday service will be 5am-12am (currently 5am-9pm) with 15-min frequencies on all lines from 5am-8pm and 30-minute frequencies from 8pm-midnight.
Does BART run at 4am?
On February 11, 2019, BART shifted its start of service from 4am to 5am on weekdays to allow extra time for a critical seismic retrofit of the Transbay Tube. The project is expected to be complete in Fall 2023. About 2,900 riders entered our system in that first hour of service.
Why does BART close early?
Closing early is a better option than running less frequently or running shorter trains after 9pm because BART will realize immediate costs savings to its operating budget by being able to reassign a significant number of operating staff to capital projects.
