Nice sense of the power of a steam engine, and great rendition of metallic textures. IMHO cropping out the bright background, including a little of the front of the locomotive, would strengthen the picture.
Strong wheels, but not going anywhere. Would be better if you didn't see the grate preventing kids from going under the train, nor the lack of tracks continuing on past the train. Also the blown out highlights at the top left draw the eyes up there and away from the power of the wheels.
