BART is gearing up for what it's calling an "epic weekend" of travel around the Bay Area.
The transit service is putting extra trains and cars on its lines this weekend because of several big events in the Bay Area.
BART's ramp-up begins today, Friday, with extra cars being added to trains during non-peak hours. Special event trains will also be added, including one for the Hardly Strictly Bluegrass festival in Golden Gate Park in San Francisco.
A dozen special event trains will run, along with extra cars on regular trains on Saturday and Sunday.
Extra station agents and technicians are also being called in.
