About 5 minutes to the end, there is a close-up of the train just about to hit the car on the tracks. It then shows the car and the people in it obviously struggling to get out before collision. Then it goes back to the train and there is a split-second pause, before hearing the impact of the train to the car. Which is too small to be real. Then it goes back to the car and it is only a minor wreck, but with a train-car collision, there would be no car. Therefore, the stop-start camera work with the close-up of the train showed the point where the crew obviously replaced the good car with a wrecked car, representing the car wrecked by the collision.
