BART trains were stalled Monday by three separate delays, but none were related to the derailment of a slow-moving train in Concord on Sunday morning.
An electrical short in a cable at 5 a.m. Monday caused delays of up to half an hour in trains traveling through the Transbay Tube between Oakland and San Francisco. Work crews completed repairs by 6:30 a.m., but delays continued for some time afterward, BART spokesman Jim Allison said.
About 8:40 a.m., BART police temporarily held up two trains -- one at West Oakland, the other at Powell Street -- because of "minor" rule violations by some passengers, Allison said. He did not have details on the nature of the offenses.
Meanwhile, BART reported that it's trying to determine the cause of the derailment that cut off train service from the Pleasant Hill-Contra Costa Centre to Pittsburg-Bay Point stations most of Sunday. The wheels of two cars on a 10-car San Francisco-bound train came off the tracks at 9:20 a.m.
BART crews restored full service to the Pittsburg-Bay Point train line early Monday before the train system opened to riders.
BART's safety department and the California Public Utilities Commission are investigating the derailment. About 65 passengers were evacuated from the derailed train, and three sought medical attention for back pain, officials said.
