Developers please note:

The trip_ids generated by the BART to Antioch system are not coordinated with trip_ids in the BART schedule system. As a result, GTFS-Realtime trip_ids for Pittsburg Center and Antioch stations (in the 600 range) have no match in GTFS. The ‘etd’ command in the BART API is unaffected. Service alerts for the BART to Antioch system are still available.

The Oakland Airport Connector system does not publish real time data for use in GTFS-Realtime or the BART API, but service alerts for the system are still available.
