Real-time arrivals for every SF Bay Area agency
Live countdowns pulled directly from each agency's real-time feed. Muni, BART, AC Transit, and SF Bay Ferry show arrival times. Caltrain and ferries show scheduled departure times. Green badge means ≤5 minutes away.
Walking time to every stop
See how long it takes to walk to any stop from where you are, adjusted for your mobility profile. Never sprint for a bus that's already gone.
