Vision has emerged of a double-decker passenger train violently smashing into the back of a semi-trailer in Utah, narrowly missing the cab where two men were seated.
Authorities in the US state are investigating why railroad crossing arms were not down and lights and bells were off when the train ripped into the FedEx trailer on Saturday morning.
The dash-cam video, released by the North Salt Lake Police, shows pieces of cardboard boxes from inside flying into the snowy air after the collision.
The two people in the cab of the truck and the 82 passengers aboard the train were not seriously injured.

Utah Transit Authority spokesman Remi Barron said authorities were trying to determine what caused the railroad crossing to be disabled.
Mr Barron said the cold and ice earlier that day forced the arms down into a safety default mode before they popped back up.
