The image shows a close-up of a steam locomotive engine. The engine is mounted on a green metal frame with a chain running along the bottom. The main focus of the image is the engine, which is visible in the center. The steam engine has two large wheels, one on each side, and a smaller wheel on the right side. The wheels are black and appear to be made of metal. There is a gold-colored valve in the middle of the engine and a small metal rod on the left side. Above the valve, there is a chain that runs along the frame. The background is blurred, but it appears to be a part of a larger machine or machinery.
