The video shows a train moving through a tunnel. The train has a series of red lights on its side, which are reflected on the walls of the tunnel. The lights create a red glow that illuminates the tunnel. The train is moving at a moderate speed, and the lights create a blurred effect as they pass by. The tunnel appears to be empty, with no other objects or people visible. The train's exterior is dark, and the red lights stand out against the dark background. The video is shot from the side of the train, and the camera angle remains constant throughout the video.
