ACWORTH, Ga. -

Dashboard camera video captured the moment when an "unstoppable" train slammed into a truck driven by a Marion County man.

Police in Georgia say 29-year-old Richard Brown of Summerfield tried to drive his tractor-trailer over the train tracks. When the trailer became stuck on the tracks, officers received word that an oncoming CSX train would not be able to stop in time.

"Get across the street," an officer can be heard yelling in the dashboard camera video. "It will not be able to stop. It's going to hit your vehicle. Get out of the truck!"

Moments later, the CSX train smashed the trailer, dragging it about a half-mile before coming to a stop.

Brown was cited for failure to obey a railroad crossing. No one in the truck or on the train was hurt.
