BART trains were recovering Wednesday morning after experiencing a number of issues, from police activity to equipment problems, that caused major delays throughout the transit system.

A disturbance on a train at the Orinda BART station around 8 a.m. caused a 20-minute delay on trains heading to San Francisco and Pittsburg-Bay Point as riders waited for police to arrive, according to BART officials.

Details on the disturbance weren’t immediately available.

A switching problem at the Daly City BART station caused delays at numerous San Francisco stations headed toward San Francisco International Airport, Millbrae, Daly City and the East Bay.

The problem had been corrected by about 8:30 a.m. and trains were starting to get back on track, BART officials said.
