BART
BART is the San Francisco Bay Area's rapid transit rail system, connecting cities across four counties with electric train service.
What is BART?
BART — the Bay Area Rapid Transit system — opened in 1972 and has been the spine of the San Francisco Bay Area's commuter rail network ever since. Running beneath Market Street in San Francisco and connecting the city to Oakland, Berkeley, Fremont, Pleasanton, Antioch, and SFO airport, BART carries hundreds of thousands of riders on weekdays and is the primary commuter option for the enormous population of tech workers, government employees, and professionals who live in the East Bay and work in San Francisco or Silicon Valley. The system runs on a broad 1,676mm track gauge — wider than standard gauge — and operates an aging but extensively modernised fleet.
BART's digital tools have expanded substantially from the original paper-ticket era. The Clipper card, the Bay Area's regional transit smart card, integrates with BART fare gates and autoloads funds when balances fall below a threshold. The BART app provides real-time train arrival information drawing from the agency's GTFS-RT (General Transit Feed Specification — Realtime) data feed, trip planning from origin to destination, elevator and escalator status for accessibility planning, and service alert notifications. Third-party apps like Google Maps and Apple Maps also consume BART's real-time data feed, so BART API failures propagate across every navigation app that Bay Area commuters use.
BART's real-time system failures create cascading effects that extend beyond the official BART app. When the real-time arrival API is degraded, platform countdown displays may go dark or show incorrect departure times, leaving riders on platforms unable to make informed decisions about whether to wait or take alternative transport. Google Maps and Apple Maps lose BART arrival data simultaneously, removing reliable transit information from the tools millions of Bay Area residents use for daily navigation. Clipper card readers becoming unresponsive at fare gates during an authentication system failure creates queues that compound the disruption caused by the underlying transit problem.
Outage.gg tracks BART service disruptions using community reports from riders across the Bay Area. If BART real-time arrivals are unavailable, the app is failing to load, or Clipper integration is experiencing issues, the live status page shows current impact from the BART rider community.
