The first of several weekend stoppages of BART service between stations in Union City and Fremont will begin Saturday.
BART crews will be working in the trackway near the Fremont station to replace an aging interlocking, which is a portion of the BART system that allows trains to move safely from one route to another.
The work will require shutdowns of train service between the Union City and Warm Springs/South Fremont stations. BART’s Green Line will also fully shut down.
Instead, bus shuttles will be provided by the Alameda-Contra Costa Transit District to transfer passengers directly between these stations. Other shuttles will make an additional stop at the Fremont station.
Passengers taking buses should expect delays of 30 to 40 minutes, the agency said.
The Orange Line will continue to run at all stations except between Union City and Warm Springs/South Fremont stations, where the bus shuttles will replace train service.
An Orange Line train will make loops between Warm Springs/South Fremont and Berryessa/North San Jose stations. The last two evening trips from Berryessa/North San Jose station, which are normally scheduled for 11:40 p.m. and 11:50 p.m., will be canceled. Riders should instead use the train that leaves at 11:26 p.m.
Riders using the bus shuttles who are headed for San Francisco should plan to transfer from an Orange Line train to a Blue Line train at Bay Fair station. Blue, Red and Yellow lines will run normally.
The work is part of BART’s larger project to improve safety and rider experience, the agency said.
The same closures will be in effect for subsequent weekends on Aug. 15-16, Aug. 29-30, Sept. 12-13 and Sept. 26-27.
