A signal problem causedsystemwide Caltrain delays Wednesday morning, a Caltrain spokeswoman said.
The problem was first noted when Caltrain began running the early trains, spokeswoman Jayme Ackemann said.
Some trains were initially delayed by more than an hour, she said. At 8:30 a.m., the delays were averaging 15 to 45 minutes.
"It's the computer software that controls the signaling system that's the problem," Ackemann said.
She said Caltrain switched to its backup software, and hoped to have trains running on time again by the evening commute.
At 3 p.m. Caltrain updated its Facebook page with the following information: "Systems appear to be operating normally as we enter the afternoon commute. No delays are reported at this time."
