Bay Transit

Bay Transit — BART Companion Bay Transit is the smarter way to ride BART. Plan your trip, track real-time departures, and stay ahead of service alerts — all in one beautifully designed app.

• Route Planning Enter your departure and arrival stations and instantly see your options. Bay Transit shows you multiple trip choices with travel times and fares — Clipper, regular, and discount rates included. Your route comes to life on an interactive map with color-coded BART lines, clearly marking every stop, transfer, and destination along the way.

• Real-Time Departures See live estimated arrival times for every train at any BART station. Know exactly which platform to head to, how many cars the train has, and whether it's running on time. Trains that are arriving now show up front so you never miss your ride.

• Service Alerts Active service disruptions appear the moment you open the app. When everything is running smoothly, you'll know that too.
