BART spokesman Jim Allison said the unexplained 6:12 a.m. outage disabled some of the rail switches at the Berkeley station -- and, just as would happen at your home, affected BART computers. When the computers were reset, it "created a further problem at the Richmond yard." The switches at the maintenance yard could not be automatically shifted, and the trains were frozen in their tracks.
BART solved this problem using brawn: Workers physically moved the switches, and the trains were on their way.
After an hour of delays, BART has been back on schedule since 7:15 a.m.
