A commuter train derailed in a rural part of northern California Monday, injuring 14 people, authorities said.
The Alameda County Fire Department said four people suffered serious but non-life threatening injuries while 10 sustained minor injuries when the train derailed in Sunol, with one of its cars tumbling into a creek.
It said all passengers had been removed from the train, which CBS San Francisco reported was traveling from San Jose to Stockton via Fremont and had 214 people on board.
Pictures from the scene posted on Twitter by the Alameda County Fire Department showed one of the train cars lying on its side and partially submerged in water.
CBS San Francisco, citing train operator officials, reported that the derailment was caused by a tree on the tracks.
