10:43 AM: Caltrain is back on schedule today after a broken train caused delays of up to an hour during the morning commute, a transit spokeswoman said.

The delays began at about 7:40 a.m. when a northbound train on its way to San Francisco broke down between Burlingame and Millbrae, Caltrain spokeswoman Christine Dunn said.

The disabled train, which had about 720 passengers on board, was back in service about 15 minutes later.

A second northbound train was delayed due to brake problems, and the two delays caused some trains to be an hour behind schedule, according to Caltrain.

By about 10 a.m., the issues had been resolved and trains were running on time throughout the system, Dunn said.
