A slide in the rain-soaked Feather River Canyon rumbled down on a 93-car Union Pacific freight train Thursday, derailing nine cars and knocking one into the Feather River, an official said.

No one was injured in the incident and the nine derailed cars were empty, a railroad spokesman said. The slide occurred near Camp Rogers between Oroville and Keddie at about 3 p.m., he said.Unusually heavy rains pelted northern California at midweek.
