Union City station is a Bay Area Rapid Transit station located in downtown Union City near the Decoto district. Service at this station began on September 11, 1972. The station sits near Decoto Road east of Alvarado-Niles Road, directly behind James Logan High School's campus. Temporary parking spaces were constructed in 2006, and opened in the Summer of 2007.The station is currently undergoing construction through 2016 to create a second entrance on the other side of the station. The new eastern station entrance will entail remodeling of the station's platforms and lobby, new bus stop shelters will be built near the entrance, and a pedestrian bridge will be built to connect the East plaza, the opening of this phase will happen at a future date.Local bus service is provided by Union City Transit and AC Transit.Union City future intermodal rail stationCurrently, no connection to other regional trains exists at Union City BART station. In February 2008, Union City's Economic Development Department and BART proposed that this station become a regional rail intermodal station. The intermodal station would serve BART trains, Capitol Corridor intercity trains, and Dumbarton Rail Corridor commuter rail service connecting to Caltrain on the Peninsula via a new rail bridge to replace the existing Dumbarton Rail Bridge. For now, the Dumbarton Express bus service provides such service to the Peninsula, operating between Union City and Palo Alto. Funding for this project went to Bart to San Jose project which would be opened in 2017, however the current status for Dumbarton Rail is unknown.
