We launched the BART ETA Feed back in 2008 -- it was one of the first real time data feeds in the industry!
But on November 15, 2013 the ETA Feed was retired. Our development efforts are focused on
more robust and popular services like the Real BART API and BART GTFS-RT which provide even more kinds
of real time data for your apps. Check out the Real BART API and GTFS-RT today.
