Shortly before 6:30 am this morning, a nine-car BART train headed from San Francisco to the East Bay through the tube "separated into two pieces." BCN (via CBS 5) reports: "A five-car section of the train was removed first with the operator on board ... Another operator then boarded the second, four-car portion, and moved it out of the way as well." Although service has since resumed,SFGate says you should "expect some residual delays ranging from 15 to 40 minutes" throughout the morning.
