California note
Union City BART is the local bus-and-rail hinge
Union City Station brings BART, Union City Transit, AC Transit, Dumbarton Express, and local fare rules together in one practical transfer point.
Union City Station is the easiest place to understand how local and regional transit meet in the city. BART handles the longer rail trip, while Union City Transit fills in shorter local movement.
The station is at 10 Union Square. Around it, Union City Transit connects with BART, AC Transit, and Dumbarton Express. The city transit page also explains local fares and transfer rules, including details that can matter when you move from BART to a bus.
That is the piece to check before you ride. A regional transit map may show the big line, but the small fare and transfer details live on the local page. If you are planning a commute, school trip, or car-light errand, start with the BART station page and then check Union City Transit for the last leg.
