This image makes great use of leading lines to emphasize movement even though there is no smoke risking from the stack. The angle of the train is mirrored in the background hill which heightens the effect. The exposure of the image is rather good as well.
Items detracting from this image are slight overexposure in the clouds and on the side of the engine.
