BART was delayed throughout the morning after a few trains were stopped for police activity and a medical response.
A train at the Pleasant Hill station was stopped at about 6 a.m. when BART police received reports that a woman had been punched by an unidentified man, BART police Lt. Gary Cagaanan said.
Neither the victim nor the suspect was at the station when police arrived, and trains were stopped while police searched the area, Cagaanan said.
Further delays were compounded by other problems, a BART dispatcher said.
BART officials received reports that a woman had fainted at the Embarcadero station this morning, so trains were stopped, the dispatcher said. Medics were unable to find the woman when they arrived, she said.
Another train was stopped at the Powell Street station when officials received reports of unattended luggage on the train, the dispatcher said.
The train was held, increasing delays, and the luggage was removed by the train operator, the dispatcher said.
