Contra Costa Air Quality

One cool thing about knowing BART arrival times (other than how long you have to wait until the next train), is seeing those trains move along the system in real time.

Meet WhereISBART.com.

Have you ever wondered how many trains were in the BART system at a given time?

Or, how far away is that next train, really?

Or, if my friends boarded BART at another station a few minutes ago, will I meet them on this train that’s arriving now?

Where is BART? updates every 15 seconds to show where your train is throughout the Bay Area.

What more details? Click on any station for arrival times to that station, or browse arrival times the old-fashioned way on BART’s website.
