San Diego County authorities have identified a tow truck driver who was killed by a train while helping a stalled vehicle at a railroad crossing.

The medical examiner's office says 27-year-old Shaun William Riddle was struck by an Amtrak train on Saturday at crossing in the Cardiff area of Encinitas.

Authorities say Riddle had stopped to help a stalled SUV just west of the tracks and was trying to hook it to his truck on the tracks when a train approached.

Riddle got back into his truck and tried to move it off the tracks but it was struck by the Amtrak Surfliner. He was thrown from the truck, which was demolished.

None of the 125 passengers aboard was seriously injured but several complained of minor pain.
