Wait times on major routes, including the Yellow, Red, Blue, and Green lines, have been updated to optimize service frequency. BART trains and schedules are undergoing major changes starting Monday, with adjusted departure times across the entire transit system. The primary goal of the schedule overhaul is to reduce wait times for commuters and create more consistent service intervals. Previously arriving 3 and 17 minutes apart, trains on these lines will now operate on wait times of 8 and 12 minutes. A full breakdown of the updated schedule is available here.
