The image shows a red and yellow train traveling through a tunnel. The train is on a railway track and is moving towards the right side of the image. The tunnel appears to be underground, as there is a concrete platform on the left side and a concrete wall on the right. The sky is foggy and there is smoke coming out of the train's engine, indicating that it is moving at a high speed. The front of the locomotive is visible, with the number "X522 003" written on it. There are two headlights on either side of it, and the train is emitting a plume of smoke. The image is taken from a low angle, looking up at the train.
