From CBS News -
A Metrolink train derailed Tuesday morning after it collided with a tractor trailer on the tracks in Ventura County, injuring at least 30 people, officials said.
The VC Line 102 train, which was headed southbound to Los Angeles, hit the truck around 5:45 a.m. near 5th Avenue and Rice Street in Oxnard, according to the Ventura County Fire Department.
"For some reason there was a tractor trailer on the tracks there at Rice Avenue and Train 102 collided with it," Scott Johnson of Metrolink told CBS Los Angeles.
The truck caught fire and four train cars derailed.
Ventura County Fire Department spokesperson Capt. Mike Lindbery said via Twitter there were no fatalities.
The driver of the truck also apparently tried to flee the scene but was later arrested. Little was left of the truck but scorched and mangled wreckage - some debris was in a nearby intersection and some close to the tracks.
One toppled train car laid with one end on the tracks and another on the street after the accident. Another passenger car derailed but didn't topple, and the locomotive also remained upright.
Metrolink reports that all Ventura County trains will experience extensive delays due to the accident.
The cause of the accident is under investigation.
