BART trains are expected to be in full service during this morning's commute with no delays.
Service was in the process of being restored around 10 p.m. and after 11 p.m. BART was running with 30 trains, although about 10 of those trains were running late, Allison said.
The glitch started at 7:35 p.m.
After normal train service ends early this morning, BART officials are expected to continue trouble shooting the computer problem throughout the night. The glitch was never considered a safety issue with train control computers never failing, Allison said.
Nevertheless, control center managers decided to off-load passengers to prevent any incidents, Allison said.
Allison said an early diagnosis of the problem was a network router issue that was incorrectly displaying data at the operations control center.
Trains were moving, but the control center was not able to monitor trains. While information was being streamed to a certain point, it wasn't getting past routers and was not feeding control displays with real-time information, Allison said.
"We are working to pinpoint the cause of it," he said.
