Shot of a stream bank with train tracks, taken from the bank of the other side of the stream. The camera follows a single-car train moving quickly on these tracks. Suddenly, a second single-car train enters from the opposite side of the frame and the two collide. Black and white steam/smoke billows from the crash, blocking one car and most of the second from the camera. CU of the two cars. Worker walks toward the crushed fronts of the trains.
