The BART Usher provides real-time BART information. It enables you to retrieve real-time train information for any station, to plan your BART trips, and to get advisories and elevator info for the system, and save favorite routes. It also includes a BART system map for reference.Note: The app retrieves info from the BART system. If there are problems with that system, the app will not behave as expected. Please don’t just assume that the app is not working. Just to be sure you can check the BART mobile website. You should see the same issues. Please do notify me of such issues. You can send me an email from within the app now.
