The image shows a train going through a tunnel at night. The tunnel appears to be made of concrete and has a curved shape. The walls of the tunnel are lit up with green and red lights, creating a tunnel-like effect. The train is moving towards the right side of the image, with its headlights on. The background is dark, making the colors of the lights stand out even more. The image is taken from a low angle, looking up at the train and the tunnel.
