This is the terrifying footage capturing the moment of impact of an Amtrak train crashing into a semi-truck in Thackerville, Oklahoma on October 15.

Four train passengers suffered injuries and were taken by ambulance to a local hospital, an Amtrak spokesperson told CNN. There were 110 passengers and crew members on Amtrak Train 822, which was running between Fort Worth, Texas, and Oklahoma City.

"There were some injured passengers on the train, and the driver of the semi and his dog are shaken up but everyone is alive," the Love County Sheriff Office wrote in a Facebook post on October 15.

Semi got stuck on the train tracks right before a passenger train was due to come through. The driver escaped but is seen in the video screaming at the train trying to flag it down. The video is shot in Thackerville Oklahoma. The videographer was right behind the stuck semi at the point of impact
