Starting in March 2022, BART will run 5-line service daily, including on Sundays. Relations 2851511, 2851509, 2851613, 2851612, 2827683, 2827686, 2827684, and 2827685 will need to be updated with new opening_hours values. Instead of specific hours from timetables, we can tag the evening relations with 21:00-00:00 based on the “9pm-Midnight” on the BART system map.
