The image shows a close-up of the front wheel of a steam locomotive. The wheel is black and appears to be made of metal, with a large hub in the center. The hub is attached to a metal frame with two bolts and a bolt on the right side. On the left side of the wheel, there is a smaller wheel with a bolt and a nut. The background is blurred, but it seems to be a part of the locomotive's engine. The image is taken from a low angle, looking up at the wheel and the frame. The floor is made of concrete and there are some wires and cables visible in the background.
