North Carolina officials are investigating a train accident in Durham that killed two children and injured their mother when their sport utility vehicle was stopped on the tracks.
Multiple media outlets report that Paul Worley of the N.C. Transportation Department says signal inspectors were checking Thursday to make sure everything was working properly.
Eyewitnesses told authorities the SUV was stopped by rush hour traffic and became trapped on the tracks when guardrails came down as the train approached.
Authorities say 9-year-old Calvin Brandon and 6-year-old Hasan Bingham were thrown from the SUV. Their mother, Deborah Peaks Bingham, was treated and released for non-life threatening injuries.
None of the 129 people on the train were injured.
