BART trains are back in service after a computer outage halted service earlier Monday evening.
Computers in BART's operations control center that monitor the location of the system's trains were back online just before 10 p.m., allowing the agency to fully restore service, according to the BART media hot line.
However, as of 10:15 p.m., 12 of 34 trains still were experiencing some residual, five- to 10-minute delays, BART spokesman Jim Allison said on the hot line.
The problem began around 7:30 p.m., and BART stopped trains at stations so that customers could get off. Though train operators remained in radio communication with train controllers at all times, BART officials halted service as a precaution, Allison said.
Shortly after 9 p.m., BART reported running "very limited service" and did not know when full service would be restored. Though trains continued to move slowly from station to station, regular BART users were advised to find alternate transportation.
MUNI and ACE Transit offered temporary aid, allowing customers to use their BART tickets to purchase rides on those systems while the problems persisted.
