BART service ramped up service to near pre-pandemic levels Monday, including the return of late-night trains.

Closing time has been extended to midnight Monday through Saturday, and trains will run more frequently, BART officials said.

The new schedule also sees an increase in direct trips to San Francisco International Airport on weekdays.

Although the revised schedule resembles the one before the pandemic, differences include areas that won’t be returning to former levels such as extra commuter trains on the Antioch-SFO (Yellow) line during peak hours, according to BART.

Weekday service is now from 5 a.m. to midnight with 5-line service and 15-minute frequencies on all lines from 5 a.m. to 8 p.m. There is also 3-line service with 30-minute frequencies from 8 p.m.-midnight.

Saturday service expands to 6 a.m. to midnight with 5-line service from 6 a.m. to 8 p.m., and then 3-line service from 8 p.m. to midnight.

Sunday service remains 8 a.m. to 9 p.m. with 3-line service and 30-minute frequencies to accommodate critical cable replacement and other infrastructure rebuilding work, BART officials said.

The schedule change means BART trains will be in service for a combined 875 hours each weekday, compared with only 498 in-service hours in mid-July — an increase of 76 percent.

On Saturdays the change results in 514 combined in-service train hours compared with only 258 the previous month for a 99 percent increase, according to BART.

The BART Trip Planner has been updated with the new schedule.
