An equipment problem Thursday morning caused major delays on BART between Pleasant Hill and Walnut Creek and slowed commutes in both directions, officials said.

“We have train control equipment which provides information to the trains about what speed to go, and where to go and all of that,” said Jim Allison, a BART spokesman. “The equipment between Pleasant Hill and Walnut Creek stopped sending routing information at 6:22 a.m.”

The malfunction caused 12 trains to be delayed, for a maximum of 30 minutes, Allison said.

He noted the issue was resolved at 7:35 a.m., and by 8:40 a.m. all residual delays had been cleared and trains were running on time.
