Here we see a medium wideshot of the group about tocross the bridge/train tracks. This shot shows you all of their surroundings and it shows how far it is to the other side of the bridge. Also in this shot gordy is holding the track to see if he can feel any vibrations of oncoming 2 trainz.
Here we see a close up of gordy. He is halfway across the bridge and he had bent down to feel the vibrationson the track and as he looked back he could see the steam coming out of the train. After all of this he yells "TRAIN" to his friends and they all gap it.
That is all
