RIALTO, Calif. - A Metrolink commuter train sideswiped a freight train Thursday, causing no serious injuries but bringing back still-vivid memories of a deadly train wreck in the region just two months ago.

The commuter train, carrying 15 passengers and crew, was heading east from downtown Los Angeles toward San Bernardino at 11:30 a.m. when it collided with a westbound BNSF train pulling onto a side track, authorities said.
